|Catabolic state in metabolic diseases||Metabolic disease, including mitochondrial disease, leads to a partial|
or complete disruption of the body’s normal chemical processes.
Certain chemicals are not turned over; these compounds build up and
create cellular toxicity; certain chemicals are not made, which
creates a cellular deficiency. When individuals with metabolic disease
undergo a normal or abnormal catabolic stress, they begin turning over
protein, carbohydrate and fat stores as they should – but due to the
inherent chemical disruption, create more than normal levels of toxic
substances and less than normal levels of the required product. In the
case of mitochondrial disease, cells are less efficient at creating
adequate energy from protein, fat and carbohydrate stores. In the
catabolic state, the cell’s need for more cellular energy is often not
met. It is during these times when the individual with mitochondrial
disease is more vulnerable to cellular injury in various organs,
including the brain. Certain organs can rapidly decompensate and enter
a state of organ failure.
|Cellular respiration||Cellular respiration is the process through which cells convert fuel|
into energy and nutrients. To create ATP and other forms of energy
that they can use to power their life functions, cells require both
fuel, and an electron acceptor which drives the chemical process of
turning energy from that fuel into a useable form.

|Common metabolic catabolic stressors in mitochondrial diseases||There are several catabolic stressors to the body, including prolonged|
fasting, illness, surgery and anesthesia. Of these, one that is faced
commonly in the pediatric and adult population is illness. Viral
illnesses are frequent occurrences in the growing child. And there is
currently no clear way to prevent a child or adult from acquiring
viral infections, though hand-washing and limiting exposures to sick
contacts/contagious persons have benefits. The patient with
mitochondrial disease is not more prone to life-threatening
infections. There is some anecdotal (experience-based) and small
study-based evidence that mitochondrial patients have more frequent
non-life-threatening viral infections such as colds, stomach-flues,
bronchitis, and ear infections. This vulnerability may be due to some,
yet unquantifiable, dysfunction of the immune system – though, to
date, all routine measures of immune function in mitochondrial
patients are normal. There is no specific treatment for mitochondrial
patients despite the potentially increased frequency of

respiratory electron transport chain of cells located in the membrane.
It receives an electron from each of four cytochrome c molecules, and
transfers them to one dioxygen molecule, converting the molecular
oxygen to two molecules of water. In this process it binds four
protons from the inner aqueous phase to make two water molecules, and
translocates another four protons across the membrane, increasing the
transmembrane difference of proton electrochemical potential which the
ATP synthase then uses to synthesize ATP.

and gender. Causes Failure to thrive may be caused by medical problems
or factors in the child’s environment, such as abuse or neglect.
|Fatty acid||A fatty acid is a carboxylic acid with a long aliphatic chain, which|
is either saturated or unsaturated. Most naturally occurring fatty
acids have an unbranched chain of an even number of carbon atoms, from
4 to 28. Fatty acids are usually not found in organisms, but instead
as three main classes of esters: triglycerides, phospholipids, and
cholesterol esters. In any of these forms, fatty acids are both
important dietary sources of fuel for animals and they are important
structural components for cells.
|Fatty acid oxidation disorder||When your body runs out of sugar, it usually breaks down fat for|

females with mild mental retardation.
|Free radical||Free radicals are formed naturally as products of metabolic processes|
and can also be introduced from outside the body through smoking,
inhaling environmental pollutants, or exposure to ultraviolet
radiation. They interact readily with nearby molecules and may cause
cellular damage, including genetic alterations. It has been theorized
that they are involved in degenerative disorders such as Alzheimer
dementia and parkinsonism, in plaque formation in atherosclerosis, and
in cancer. Natural enzymes such as superoxide dismutase and peroxidase
are thought to counteract free radicals, and there is evidence that
many nutrients, including vitamins C and E and beta-carotene, also
exert an antioxidant effect.
|Gastric dismotility||Gastric Dysmotility occurs when the intestinal tract loses its ability|
to coordinate the muscular contractions of the bowel. With intestinal
dysmotility, certain muscles, including the esophagus, stomach, small

from the stomach into the small intestine because of impaired stomach
motility, resulting in nausea, vomiting, and a feeling of fullness.
|Gene||Gene is one of the biologic units of heredity, self-reproducing, and|
located at a definite position (locus) on a particular chromosome.
Genes make up segments of the complex deoxyribonucleic acid (DNA)
molecule that controls cellular reproduction and function. There are
thousands of genes in the chromosomes of each cell nucleus; they play
an important role in heredity because they control the individual
physical, biochemical, and physiologic traits inherited by offspring
from their parents. Through the genetic code of DNA they also control
the day-to-day functions and reproduction of all cells in the body.
For example, the genes control the synthesis of structural proteins
and also the enzymes that regulate various chemical reactions that
take place in a cell. The gene is capable of replication. When a cell
multiplies by mitosis each daughter cell carries a set of genes that
is an exact replica of that of the parent cell. This characteristic of
replication explains how genes can carry hereditary traits through
successive generations without change.
|Genetic||Genetic – pertaining to reproduction, birth, or origin; pertaining to|
genetics or heredity; pertaining to or produced by a gene; inherited.
|Genetic Counseling||Genetic counseling aims to facilitate the exchange of information|
regarding a person’s genetic legacy. It attempts to: accurately
diagnose a disorder; assess the risk of recurrence in the concerned
family members and their relatives; provide alternatives for
decision-making; provide support groups that will help family members
cope with the recurrence of a disorder.
|Genetic disease||A genetic disease is any disease caused by an abnormality in the|
genetic makeup of an individual. The genetic abnormality can range
from minuscule to major — from a discrete mutation in a single base
in the DNA of a single gene to a gross chromosomal abnormality
involving the addition or subtraction of an entire chromosome or set
|Genome||Genome is the complete set of genes or genetic material present in a|
cell or organism.
|Genome sequencing||Genome sequencing is figuring out the order of DNA nucleotides, or|
bases, in a genome—the order of As, Cs, Gs, and Ts that make up an
organism’s DNA. The human genome is made up of over 3 billion of these
genetic letters. Genome sequencing is often compared to “decoding,”
but a sequence is still very much in code. In a sense, a genome
sequence is simply a very long string of letters in a mysterious
language. When you read a sentence, the meaning is not just in the
sequence of the letters. It is also in the words those letters make
and in the grammar of the language. Similarly, the human genome is
more than just its sequence. Imagine the genome as a book written
without capitalization or punctuation, without breaks between words,
sentences, or paragraphs, and with strings of nonsense letters
scattered between and even within sentences.
|Gastroesophageal reflux disease (GERD)||Gastroesophageal Reflux Disease is a condition in which acidic gastric|
fluid flows backward into the esophagus, resulting in heartburn.
|Global delay||A global developmental delay is when kids have delays in at least two|
areas. Many parents and caregivers worry that their child’s delays are
somehow their fault. But developmental delays are typically caused by
things beyond your control. For example, teaching a child more than
one language doesn’t lead to speech or language problems.

levels.Glucophage is used together with diet and exercise to improve
blood sugar control in adults with type 2 diabetes mellitus.
|Glucose||Glucose is a simple sugar with the molecular formula C₆H₁₂O₆. Glucose|
is the most abundant monosaccharide, a subcategory of carbohydrates.

used to make cellulose in cell walls, which is the most abundant
carbohydrate. In energy metabolism, glucose is the most important
source of energy in all organisms. Glucose for metabolism is partially
stored as a polymer, in plants mainly as starch and amylopectin and in
animals as glycogen. Glucose circulates in the blood of animals as
|Glutathione metabolism||Glutathione is an antioxidant in plants, animals, fungi, and some|
bacteria and archaea. Glutathione is capable of preventing damage to
important cellular components caused by reactive oxygen species such
as free radicals, peroxides, lipid peroxides, and heavy metals. It is
a tripeptide with a gamma peptide linkage between the carboxyl group
of the glutamate side chain and cysteine. The carboxyl group of the
cysteine residue is attached by normal peptide linkage to glycine.
|Gluten||Gluten is a group of proteins, called prolamins and glutelins, which|
occur with starch in the endosperm of various cereal grains. This
protein complex comprises 75–85% of the total protein in bread wheat.

degradation) is the metabolic pathway that converts glucose C6H12O6,
into pyruvate, CH3COCOO + H. The free energy released in this process
is used to form the high-energy compounds ATP (adenosine triphosphate)
and NADH (reduced nicotinamide adenine dinucleotide).
|Gross motor skills||Gross motor skills are movements that involve large muscle groups and|
are generally more broad and energetic than fine motor movements.
These include walking, kicking, jumping, and climbing stairs. Some
milestones for gross motor skills also involve eye-hand coordination,
such as throwing or catching a ball.
|Heat intolerance||Heat Intolerance is an uncomfortable feeling of being overheated in|
|Hemophilia||Hemophilia is caused by deficiency of clotting factors, a certain type|
of protein in the body. Major symptoms include unexplained bleeding,
blood in urine or stool. Treatment involves injections of the
insufficient clotting factors or plasma.

occurs when blood sugar (or blood glucose) concentrations fall below a
level necessary to properly support the body’s need for energy and
stability throughout its cells.
|Hypotonia||Hypotonia is reduced tension in any part, as in the eyeball;|
Relaxation of the arteries; A condition in which there is a diminution
or loss of muscular tonicity.
|Hypoxia||Hypoxia is diminished availability of oxygen to the body tissues; its|
causes are many and varied and includes a deficiency of oxygen in the
atmosphere, as in altitude sickness; pulmonary disorders that
interfere with adequate ventilation of the lungs; anemia or
circulatory deficiencies, leading to inadequate transport and delivery
of oxygen to the tissues; and finally, edema or other abnormal
conditions of the tissues themselves that impair the exchange of
oxygen and carbon dioxide between capillaries and tissues.
|Individuals with Disailities Act||The Individuals with Disabilities Education Act is a four-part piece|
of American legislation that ensures students with a disability are
provided with Free Appropriate Public Education that is tailored to
their individual needs. IDEA was previously known as the Education for
All Handicapped Children Act from 1975 to 1990. In 1990, the United
States Congress reauthorized EHA and changed the title to IDEA.
Overall, the goal of IDEA is to provide children with disabilities the
same opportunity for education as those students who do not have a
|Idiopathic||An idiopathic disease is any disease with an unknown cause or|
mechanism of apparent spontaneous origin. From Greek ἴδιος idios
“one’s own” and πάθος pathos “suffering”, idiopathy means
approximately “a disease of its own kind”. For some medical
conditions, one or more causes are somewhat understood, but in a
certain percentage of people with the condition, the cause may not be
readily apparent or characterized. In these cases, the origin of the
condition is said to be idiopathic. With some other medical
conditions, the root cause for a large percentage of all cases have
not been established—for example, focal segmental glomerulosclerosis
or ankylosing spondylitis; the majority of these cases are deemed
|Individual Family Service Place (IFSP)||An Individual Family Service Plan (IFSP) is a plan for special|
services for young children with developmental delays. An IFSP only
applies to children from birth to three years of age. The IFSP is
developed with service coordinator for a Part C eligible child and
family. The service is available “Part C” (formerly Part H) of the
Individuals with Disabilities Education Act (IDEA) The IFSP is set up
to identify individualized supports and services that will enhance the
child’s development. The IFSP is usually done at 6 month intervals but
can be done more often if necessary. The plan must include an
assessment of child’s present level of development, a statement of
goals, support services that will be put in place to achieve those
goals, date services will begin, name and identification of the
|Individualized Education Program (IEP)||Once a child turns 3 years old, an Individualized Education Program|
(IEP) is put into place. This program was created by US Public Law
99-457.1 An IEP strictly revolves around the student, because it’s the
child’s education which is being discussed.
|Insensible Fluid Loss||Insensible loss (insensible water loss) is the amount of fluid lost on|

second section of the small intestine. In many cases, a jejunostomy
tube will help to provide nutrition for a terminally ill patient.
|Jejunum||The jejunum is the second part of the small intestine in humans and|
most higher vertebrates, including mammals, reptiles, and birds. Its
lining is specialized for the absorption by enterocytes of small
nutrient molecules which have been previously digested by enzymes in
the duodenum. The jejunum lies between the duodenum and the ileum and
is considered to start at the suspensory muscle of the duodenum, a
location called the duodenojejunal flexure. The division between the
jejunum and ileum is not anatomically distinct. In adult humans, the
small intestine is usually 6-7m long, about two-fifths of which (2.5
m) is the jejunum.

promote the metabolism of fats into ketone bodies (rather than
carbohydrates into glucose) to provide the body’s main source of
|Kidney dysfunction||Kidney Dysfunction is disturbance, impairment, or abnormality of|
|Kreb’s Cycle||Kreb’s cycle (also known as Citric Acid Cycle or Tricarboxylic Acid|
Cycle) is a step wise cyclic process which is used to oxidize the
pyruvate formed during the glycolytic breakdown of glucose into Carbon
Dioxide (CO 2) and Water (H 2 O). It also oxidizes acetyl CoA which
arises from breakdown of carbohydrate, lipid, and protein
|Lactated ringer’s (LR)||Lactated Ringer’s solution, also known as sodium lactate solution and|
Hartmann’s solution, is a mixture of sodium chloride, sodium lactate,
potassium chloride, and calcium chloride in water. It is used for
replacing fluids and electrolytes in those who have low blood volume
or low blood pressure. It may also be used to treat metabolic acidosis
and to wash the eye following a chemical burn. It is given by
injection into a vein or applied to the affected area.
|Lactic acid||Lactic acid is an organic acid. It has a molecular formula|
CH₃CH(OH)CO₂H. It is white in solid state and it is miscible with
water. While in liquid state it is a colorless solution. Production
includes both artificial synthesis as well as natural sources. Lactic
acid is an alpha-hydroxy acid due to the presence of carboxyl group
adjacent to the hydroxyl group. It is used as a synthetic intermediate
in many organic synthesis industries and in various biochemical
industries. The conjugate base of lactic acid is called lactate.
|Lactic acidosis||Lactic acidosis is a medical condition characterized by the buildup of|
lactate in the body, with formation of an excessively low pH in the
bloodstream. It is a form of metabolic acidosis, in which excessive
acid accumulates due to a problem with the body’s oxidative
|Leber’s Hereditary optic neuropathy (LHON)||Leber’s hereditary optic neuropathy (LHON) or Leber hereditary optic|
atrophy is a mitochondrially inherited (transmitted from mother to
offspring) degeneration of retinal ganglion cells (RGCs) and their
axons that leads to an acute or subacute loss of central vision; this
affects predominantly young adult males.
|Leigh’s disease||Leigh’s syndrome (also called Leigh disease and subacute necrotizing|
encephalomyelopathy) is an under-recognized inherited neurometabolic
disorder that affects the central nervous system. It is named after
Archibald Denis Leigh, a British neuropsychiatrist who first described
the condition in 1951. Normal levels of thiamine, thiamine
monophosphate, and thiamine diphosphate are commonly found but there
is a reduced or absent level of thiamine triphosphate. This is thought
to be caused by a blockage in the enzyme thiamine-diphosphate kinase,
and therefore treatment in some patients would be to take thiamine
|Lethargy||Lethargy is a state of tiredness, weariness, fatigue, or lack of|
energy. It can be accompanied by depression, decreased motivation, or
apathy. Lethargy can be a normal response to inadequate sleep,
overexertion, overworking, stress, lack of exercise, improper
nutrition, boredom, or a symptom of an illness or a disorder. It may
also be a side-effect of medication or caused by an interaction
between medications or medication(s) and alcohol. When part of a
normal response, lethargy often resolves with rest, adequate sleep,
decreased stress, physical exercise and good nutrition.
Lethargy’s symptoms can last days or even months.
|Leukodystrophy||Leukodystrophy is one of a group of disorders characterized by|
degeneration of the white matter in the brain. The word
leukodystrophy comes from the Greek roots leuko, “”white””, dys,
“”abnormal””, and troph, “”growth””. The leukodystrophies are caused
by imperfect growth or development of the myelin sheath, the fatty
insulating covering around nerve fibers. When damage occurs to
white matter, immune responses can lead to inflammation in the central
nervous system (CNS), along with loss of myelin. The degeneration of
white matter can be seen in an MRI scan and used to diagnose
leukodystrophy. Leukodystrophy is characterized by specific symptoms
including decreased motor function, muscle rigidity, and eventual
degeneration of sight and hearing. While the disease is fatal, the age
of onset is a key factor as infants are given a lifespan of 2–8 years
(sometimes longer), while adults typically live more than a decade
after onset. Treatment options are limited, although hematopoietic
stem cell transplantations using bone marrow or cord blood seem to
help in certain types while further research is being done.
|Magnetic resonance imaging (MRI)||Magnetic resonance imaging (MRI) is a medical imaging technique used|
in radiology to form pictures of the anatomy and the physiological
processes of the body. MRI scanners use strong magnetic fields,
magnetic field gradients, and radio waves to generate images of the
organs in the body. MRI does not involve X-rays or the use of ionizing
radiation, which distinguishes it from CT or CAT scans and PET scans.
Magnetic resonance imaging is a medical application of nuclear
magnetic resonance (NMR). NMR can also be used for imaging in other
NMR applications such as NMR spectroscopy.
|Magnetic resonance spectroscopy (MRS)||Magnetic Resonance Spectroscopy (MRS) is a noninvasive technique that|
is similar to magnetic resonance imaging but uses a stronger field and
is used to monitor body chemistry (as in metabolism or blood flow)
rather than anatomical structures —abbreviation MRS.

the administration of general anesthesia.
|Malnutrition||Malnutrition definition is – faulty nutrition due to inadequate or|
unbalanced intake of nutrients or their impaired assimilation or
|Maternal mitochondrial DNA mutation inhertiance (mtDNA)||Mitochondrial DNA is never mixed with the father’s DNA, so the red|
circle pedigree line above remains unbroken and intact and is passed
from mothers to all of their children, as you can see in the brother
and sister at the bottom. Only females pass mitochondrial DNA on to
their children, so all children carry their mother’s mtDNA thus why
the term Maternal Mitochondrial DNA mutation inheritance (mtDNA)/.

life-threatening illness caused by a bacterium (especially the
meningococcus, Neisseria meningitides, or the serotype designated B of
Haemophilus influenzae). Note: Meningitis is often marked by fever,
headache, vomiting, malaise, and stiff neck, and if left untreated in
bacterial forms, may progress to confusion, stupor, convulsions, coma,

or other medications, but it is not for treating type 1 diabetes.
|Migrane||Migraine is a condition marked by recurring moderate to severe|
headache with throbbing pain that usually lasts from four hours to
three days, typically begins on one side of the head but may spread to
both sides, is often accompanied by nausea, vomiting, and sensitivity
to light or sound, and is sometimes preceded by an aura and is often
followed by fatigue.
|Mitochondrial recessive ataxia syndrome (MIRAS)||Ataxia neuropathy spectrum now includes the conditions previously|
called mitochondrial recessive ataxia syndrome (MIRAS) and sensory
ataxia neuropathy dysarthria and ophthalmoplegia (SANDO). As the name
implies, people with ataxia neuropathy spectrum typically have
problems with coordination and balance (ataxia) and disturbances in
nerve function (neuropathy).
|Mito cocktail||The mito cocktail refers to the group of vitamins and supplements used|
by patients with mitochondrial disease to help the body improve energy
production at the cellular level.
|Mitochondria||Definition of mitochondrion ( plural mitochondria) : any of various|
round or long cellular organelles of most eukaryotes that are found
outside the nucleus, produce energy for the cell through cellular
respiration, and are rich in fats, proteins, and enzymes.
|Mitochondrial diseases||Mitochondrial diseases are a group of disorders caused by|
dysfunctional mitochondria, the organelles that generate energy for
the cell. Mitochondria are found in every cell of the human body
except red blood cells, and convert the energy of food molecules into
the ATP that powers most cell functions.
|Mitochondiral neurogastrointestinal encephalopathy (MNGIE)||Mitochondrial neurogastrointestinal encephalopathy syndrome (MNGIE) is|
a rare autosomal recessive mitochondrial disease. It has been
previously referred to as polyneuropathy, ophthalmoplegia,
leukoencephalopathy, and POLIP syndrome. The disease presents in
childhood, but often goes unnoticed for decades.
|Mitochondrial oxidative stress||Mitochondrial oxidative stress is characterized by the overproduction|
of reactive oxygen species, which can induce mitochondrial DNA
mutations, damage the mitochondrial respiratory chain, alter membrane
permeability, and influence Ca2+ homeostasis and mitochondrial defense
|Molecular diagnosis||Molecular diagnosis is a technique used to analyse biological markers|
in the genome and proteome—the individual’s genetic code and how their
cells express their genes as proteins—by applying molecular biology to
medical testing. The technique is used to diagnose and monitor
disease, detect risk, and decide which therapies will work best for
|Genetic diagnosis||Preimplantation genetic diagnosis (PGD) is a procedure used prior to|
implantation to help identify genetic defects within embryos. This
serves to prevent certain genetic diseases or disorders from being
passed on to the child. The embryos used in PGD are usually created
during the process of in vitro fertilization (IVF).
|Moelcular DNA sequencing||DNA sequencing is the process of determining the nucleic acid sequence|
– the order of nucleotides in DNA. It includes any method or
technology that is used to determine the order of the four bases:
adenine, guanine, cytosine, and thymine.
|Molecular testing||Molecular testing (also called biomarker testing) looks for biological|
changes in genes or proteins, like EGFR or ALK, that may be associated
with your cancer. In most cases, this involves testing a piece of
tissue from the cancer (a biopsy).
|Motility||Motility is the ability to move spontaneously and actively, consuming|
energy in the process. Motility is genetically determined (see genetic
determinism) but may be affected by environmental factors.
|Motor delay||Motor Delay refers to children showing unusually slow development of|
fine-motor or gross-motor abilities. Fine motor abilities include
things like grasping a pencil or handling a spoon.
|Motor movement disorders||Motor movement disorders are disorders of the nervous system that|
cause abnormal and involuntary movements. They can result from damage
to the motor system. Motor disorders are defined in the fifth edition
of the Diagnostic and Statistical Manual of Mental Disorders –
published in 2013 to replace the fourth text revision – as a new
sub-category of neurodevelopmental disorders. The DSM-5 motor
disorders include developmental coordination disorder, stereotypic
movement disorder, and the tic disorders including Tourette syndrome.
|Muscle biopsy||A muscle biopsy is a procedure used to diagnose diseases involving|
muscle tissue. Your healthcare provider will remove tissue and cells
from a specific muscle and view them microscopically. Your provider
will only need to remove a small piece of tissue from the designated
muscle. Your doctor takes the tissue sample by inserting a biopsy
needle into your muscle. If a larger sample is required, your
healthcare provider may make an incision in your skin (open biopsy)
and remove a larger section of muscle. The muscle selected for your
biopsy depends on the location of symptoms, which may include pain or
weakness. The muscles often selected for sampling are the bicep (upper
arm muscle), deltoid (shoulder muscle), or quadriceps (thigh muscle).
|Genetic mutation||Some inherited genetic mutations can be good for the offspring. Some|
inherited genetic mutations cause few forms of cancer. Different
genetic mutations cause few forms of cancer. Somatic mutations can be
inherited from parents or acquired during life. Genetic mutations that
cause diseases are always passed on to offspring.
|Myasthenia gravis||Myasthenia gravis (my-us-THEE-nee-uh GRAY-vis) is characterized by|
weakness and rapid fatigue of any of the muscles under your voluntary
control. It’s caused by a breakdown in the normal communication
between nerves and muscles. There’s no cure for myasthenia gravis, but
treatment can help relieve signs and symptoms, such as weakness of arm
or leg muscles, double vision, drooping eyelids, and difficulties with
speech, chewing, swallowing and breathing. Though this disease can
affect people of any age, it’s more common in women younger than 40
and in men older than 60.

jointly involving or affecting nervous and muscular elements”.
|Neurontin||Neurontin is an anti-epileptic drug, also called an anticonvulsant.It|
affects chemicals and nerves in the body that are involved in the
cause of seizures and some types of pain. Neurontin is used in adults
to treat neuropathic pain (nerve pain) caused by herpes virus or
shingles (herpes zoster).. The Neurontin is also used to treat
seizures in adults and children who are at least 3 years old.
|Neropathic pain||Neuropathic pain is pain caused by damage or disease affecting the|
somatosensory nervous system. Neuropathic pain may be associated with
abnormal sensations called dysesthesia or pain from normally
non-painful stimuli. It may have continuous and/or episodic
components. The latter resemble stabbings or electric shocks. Common
qualities include burning or coldness, “pins and needles” sensations,
numbness and itching.
|Neuropathy||Neuropathy, or nerve damage, can result from a wide range of|
conditions such as diabetes and even treatments like chemotherapy. In
fact, neuropathy, which is sometimes referred to as peripheral
neuropathy, is not a single health condition but rather a term used to
describe a range of health problems involving damage to the peripheral
nerves, as well as the symptoms of those issues. While the group of
conditions is irreversible, you can take steps to help prevent
neuropathy or manage it through diet, lifestyle, and treatment.
|Neuropathy, ataxis and retinities pigemntosa (NARP)||Neuropathy, ataxia, and retinitis pigmentosa, also known as NARP|
syndrome, is a rare disease with mitochondrial inheritance that causes
a variety of signs and symptoms chiefly affecting the nervous system
Beginning in childhood or early adulthood, most people with NARP
experience numbness, tingling, or pain in the arms and legs; muscle
weakness; and problems with balance and coordination. Many affected
individuals also have vision loss caused by changes in the
light-sensitive tissue that lines the back of the eye. In some cases,
the vision loss results from a condition called retinitis pigmentosa.
This eye disease causes the light-sensing cells of the retina
gradually to deteriorate.
|Neuropsychological evaluation (NPE)||Neuropsychological or also known as Neuropsychological Evaluation|
(NPE) is an important component of the assessment and treatment of
brain injury, dementia, neurological conditions, and psychological and
psychiatric disorders. Neuropsychological testing is also an important
tool for examining the effects of toxic substances and medical
conditions on brain functioning.
|Neropsychological issue||Neuropsychological issues are the structure and function of the brain|
as they relate to specific psychological processes and behaviors. It’s
an experimental field of psychology that aims to understand how
behavior and cognition are influenced by brain functioning and is
concerned with the diagnosis and treatment of behavioral and cognitive
effects of neurological disorders.
|Neuropsychological testing||Neuropsychological testing (unlike bedside cognitive and behavioral|
neurologic screens) are standardized, meaning that they are given in
the same manner to all patients and scored in a similar manner time
after time. An individual’s scores on tests are interpreted by
comparing their score to that of healthy individuals of a similar
demographic background (i.e., of similar age, education, gender,
and/or ethnic background) and to expected levels of functioning. In
this way, a neuropsychologist can determine whether one’s performance
on any given task represents a strength or weakness.
|Neuropsychological||Neuropsychology studies the structure and function of the brain as|
they relate to specific psychological processes and behaviors. It’s an
experimental field of psychology that aims to understand how behavior
and cognition are influenced by brain functioning and is concerned
with the diagnosis and treatment of behavioral and cognitive effects
of neurological disorders.
|Neutropenia||Neutropenia is the presence of abnormally few neutrophils in the|
blood, leading to increased susceptibility to infection. It is an
undesirable side effect of some cancer treatments.
|NPO||Neutropenia means “nothing by mouth”. While meaning nothing by mouth|
it is derived from the Latin words, “nil per os”, thus why it is
|Nuclear DNA||Nuclear DNA, or nuclear deoxyribonucleic acid (nDNA), is DNA contained|
within a nucleus of eukaryotic organisms. Nuclear DNA encodes for the
majority of the genome in eukaryotes, with DNA located in mitochondria
and plastids coding for the rest.
|Obsessive compulsive disoder (OCD)||Obsessive-Compulsive Disorder (OCD) is a common, chronic and|
long-lasting disorder in which a person has uncontrollable,
reoccurring thoughts (obsessions) and behaviors (compulsions) that he
or she feels the urge to repeat over and over.
|Occupational therapy||Occupational therapy is the use of assessment and intervention to|
develop, recover, or maintain the meaningful activities, or
occupations, of individuals, groups, or communities. It is an allied
health profession performed by occupational therapists and
occupational therapy assistants. OTs often work with people with
mental health problems, disabilities, injuries, or impairments.
|Oculocraniosomatic disease||Oculocraniosomatic Disease, also known as, Kearns–Sayre syndrome (KSS)|
is a mitochondrial myopathy with a typical onset before 20 years of
age. KSS is a more severe syndromic variant of chronic progressive
external ophthalmoplegia (abbreviated CPEO), a syndrome that is
characterized by isolated involvement of the muscles controlling
movement of the eyelid (levator palpebrae, orbicularis oculi) and eye
(extra-ocular muscles). This results in ptosis and ophthalmoplegia
respectively. KSS involves a combination of the already described CPEO
as well as pigmentary retinopathy in both eyes and cardiac conduction
abnormalities. Other symptoms may include cerebellar ataxia, proximal
muscle weakness, deafness, diabetes mellitus, growth hormone
deficiency, hypoparathyroidism, and other endocrinopathies. In both
of these diseases, muscle involvement may begin unilaterally but
always develops into a bilateral deficit, and the course is
progressive. This discussion is limited specifically to the more
severe and systemically involved variant.
|OHI||OHI is a popular indicator developed in 1960 to determine oral hygiene|
status in epidemiological studies. The index consists of an oral
debris score and a calculus score. Six indicator teeth are examined
for soft deposits and calculus. Numerical values are assigned to the
six indicator teeth according to the extraneous deposits present. The
scores are added and divided by the number of surfaces examined to
calculate the average oral hygiene score.
|Optic nerve atrophy||Optic nerve atrophy also known as Optic Neuropathy is damage to the|
optic nerve from any cause. Damage and death of these nerve cells, or
neurons, leads to characteristic features of optic neuropathy. The
main symptom is loss of vision, with colors appearing subtly washed
out in the affected eye. On medical examination, the optic nerve head
can be visualised by an ophthalmoscope. A pale disc is characteristic
of long-standing optic neuropathy. In many cases, only one eye is
affected and patients may not be aware of the loss of color vision
until the doctor asks them to cover the healthy eye.
|Organelle||Organelle is a specialized cellular part (such as a mitochondrion,|
chloroplast, or nucleus) that has a specific function and is
considered analogous to an organ.
|Organic acidemia||Organic acidemia, is a term used to classify a group of metabolic|
disorders which disrupt normal amino acid metabolism, particularly
branched-chain amino acids, causing a buildup of acids which are
usually not present.
|Clinical trial||Clinical trial is a scientifically controlled study of the safety and|
effectiveness of a therapeutic agent (such as a drug or vaccine) using
consenting human subjects.
|Osmotic laxative||Osmotic Laxatives, purgatives, or aperients are substances that loosen|
stools and increase bowel movements. They are used to treat and
prevent constipation. Laxatives vary as to how they work and the side
effects they may have. Certain stimulant, lubricant and saline
laxatives are used to evacuate the colon for rectal and bowel
examinations, and may be supplemented by enemas under certain
circumstances. Sufficiently high doses of laxatives may cause
|Oxidative phosphorylation (OX-PHOS)||Oxidative phosphorylation (OX-phos) IS the synthesis of ATP by|
phosphorylation of ADP for which energy is obtained by electron
transport and which takes place in the mitochondria during aerobic
|Oxidative stress||Oxidative stress reflects an imbalance between the systemic|
manifestation of reactive oxygen species and a biological system’s
ability to readily detoxify the reactive intermediates or to repair
the resulting damage. Disturbances in the normal redox state of cells
can cause toxic effects through the production of peroxides and free
radicals that damage all components of the cell, including proteins,
lipids, and DNA. Oxidative stress from oxidative metabolism causes
base damage, as well as strand breaks in DNA. Base damage is mostly
indirect and caused by reactive oxygen species generated, e.g. O₂⁻, OH
and H₂O₂. Further, some reactive oxidative species act as cellular
messengers in redox signaling. Thus, oxidative stress can cause
disruptions in normal mechanisms of cellular signaling.
|Palliative Care||Palliative care is an interdisciplinary approach to specialized|
medical and nursing care for people with chronic conditions. It
focuses on providing relief from the symptoms, pain, physical stress,
and mental stress at any stage of illness. The goal is to improve
quality of life for both the person and their family. Evidence as of
2016 supports palliative care’s efficacy in the improvement of a
patient’s quality of life. Palliative care is provided by a team of
physicians, nurses, physiotherapists, occupational therapists,
speech-language pathologists and other health professionals who work
together with the primary care physician and referred specialists and
other hospital or hospice staff to provide additional support. It is
appropriate at any age and at any stage in a serious illness and can
be provided as the main goal of care or along with curative treatment.
Although it is an important part of end-of-life care, it is not
limited to that stage. Palliative care can be provided across multiple
settings including in hospitals, at home, as part of community
palliative care programs, and in skilled nursing facilities.
Interdisciplinary palliative care teams work with people and their
families to clarify goals of care and provide symptom management,
psycho-social, and spiritual support. Physicians sometimes use the
term palliative care in a sense meaning palliative therapies without
curative intent, when no cure can be expected (as often happens in
late-stage cancers). For example, tumor debulking can continue to
reduce pain from mass effect even when it is no longer curative. A
clearer usage is palliative, noncurative therapy when that is what is
meant, because palliative care can be used along with curative or
aggressive therapies.Medications and treatments are said to have a
palliative effect if they relieve symptoms without having a curative
effect on the underlying disease or cause. This can include treating
nausea related to chemotherapy or something as simple as morphine to
treat the pain of broken leg or ibuprofen to treat pain related to an
|Exocrine pancreatic insufficiency||Exocrine pancreatic insufficiency is the inability to properly digest|
food due to a lack of digestive enzymes made by the pancreas. EPI is
found in humans afflicted with cystic fibrosis and Shwachman–Diamond
syndrome, and is common in dogs. EPI is caused by a progressive loss
of the pancreatic cells that make digestive enzymes; loss of digestive
enzymes leads to maldigestion and malabsorption of nutrients from
normal digestive processes.

out of your blood.
|Pyruvate dehydrogenase complex (PDC)||Pyruvate dehydrogenase complex (PDC) is a complex of three enzymes|
that convert pyruvate into acetyl-CoA by a process called pyruvate
decarboxylation. Acetyl-CoA may then be used in the citric acid cycle
to carry out cellular respiration, and this complex links the
glycolysis metabolic pathway to the citric acid cycle.
|Pyruvate dehyrdogenase complex deficiency (PDCD)||Pyruvate dehydrogenase deficiency (also known as pyruvate|

(i.e. an epileptic seizure).
|Selective serotonin reuptake inhibitor (SSRI)||SSRI definition is – any of a class of antidepressants (such as|
fluoxetine) that inhibit the inactivation of serotonin by blocking its
reuptake by presynaptic neuron endings —called also selective
serotonin reuptake inhibitor.
|Sensorineural deafness, also known as Sensorineural Hearing Loss|
|Sensorineural Hearing Loss (SNHL) is due to problems of the inner ear,|
also known as nerve-related hearing loss.
|Sensory processing disorder or SPD, originally called Sensory|
|Sensory Processing Disorder or SPD (originally called Sensory|
Integration Dysfunction) is a neurological disorder in which the
sensory information that the individual perceives results in abnormal
responses. Sensory processing refers to the way the nervous system
receives messages from the senses and turns them into responses.
|Sensory peripheral neuropathy||Sensory peripheral neuropathy can make a simple task such as walking|
into a store or physician’s office a difficult one. Sensory peripheral
neuropathy impedes your ability to feel or “sense” your feet, making
it difficult to keep a steady gait. You may lose your balance and
become more prone to falls.
|Sensory processing disorder (SPD)||Sensory Processing Disorder is currently a symptom or an “other”|
(meaning SPD doesn’t exist) The DSM-5 lists sensory processing issues
as a symptom of a number of mental health conditions. The ICD book
lists “sensory integration disorder” under F88; however, this code is
classified as an “other condition”.
|Serum ALT/ AST||A normal serum ALT test result can range from 7-55 units per liter|
(U/L); levels are normally higher in men; slightly high ALT levels may
be caused by: Alcohol abuse, Cirrhosis (long-term damage and scarring
of the liver), Mononucleosis, and drugs such as statins, aspirin, and
some sleep aids. Aspartate aminotransferase (also known as AST or
glutamic-oxaloacetic transaminase) is an enzyme that promotes transfer
of an amino group from glutamic acid to oxaloacetic acid and that when
present in abnormally high levels in the blood is a diagnostic
indication of heart attack or liver disease.
|Short bowel syndrome||Short bowel syndrome is defined as malabsorption from the small|
intestine that is marked by diarrhea, malnutrition, and steatorrhea
and that results from resection of the small intestine.
|Smooth muscle dysfunction||Multisystemic Smooth Muscle Dysfunction Syndrome is a disease in which|
the activity of smooth muscle throughout the body is impaired This
leads to widespread problems including blood vessel abnormalities, a
decreased response of the pupils to light, a weak bladder, and
weakened contractions of the muscles used for the digestion of food
|Skeletal muscle||Skeletal muscle dysfunction is very common in patients with COPD, and|
may play an important role in limiting exercise performance in these
patients. Muscle strength and endurance are both decreased and the
muscle is more easily fatigued. Muscle atrophy is largely responsible
for the reduction in muscle strength.
|Soft signs||Soft signs are any of a number of signs that, considered collectively,|
are felt to indicate the presence of damage to the central nervous
system. These signs include incoordination, visual motor difficulties,
nystagmus, the presence of associated movements, and difficulties with
|Speech Delay||Speech delays in toddlers are common. In fact, language and speech|
problems are the most common type of developmental delay. Speech
refers to verbal expression, including the way words are formed.
Language is a broader system of expressing and receiving information,
such as being able to understand gestures.
|Speech, language, oral-motor therapy||Speech and language oral motor therapy is considered to be an|
effective approach when it comes to treating speech and language
disorders. Aside from being useful in improving speech production, it
is also capable of treating a lot of issues linked to feeding. If you
have a child who is facing difficulty in moving food around using his
tongue and chew it, then the therapy can work perfectly in improving
his condition. If provided by a competent and effective speech
language pathologist, the therapy can even be expected to offer a
great number of advantages.
|Stamina||Stamina is the bodily or mental capacity to sustain a prolonged|
stressful effort or activity : endurance
|Statins||Statins are any of a group of drugs (such as lovastatin and|
simvastatin) that inhibit the synthesis of cholesterol and promote the
production of LDL-binding receptors in the liver resulting in a
usually marked decrease in the level of LDL and a modest increase in
the level of HDL circulating in blood plasma. Statins are one of the
medications that should generally be avoided during times of illness
in individuals with mitochondrial disease.
|Stroke||A stroke is a sudden diminution or loss of consciousness, sensation,|
and voluntary motion caused by rupture or obstruction (as by a clot)
of a blood vessel of the brain; also called apoplexy, brain attach,
and cerebrovascular accident.
|Swallow dysfunction||Swallowing dysfunction is a late complication of nephropathic|
cystinosis, probably related to muscular dysfunction. Changes in the
consistency of foods, swallowing exercises, and long-term cysteamine
therapy should be considered for patients with cystinosis who have
difficulty in swallowing.
|Swallow study||Commonly referred to as the barium swallow study, swallow study is a|
radiological examination that helps in visualization of the esophagus
for diagnostic purposes. It involves swallowing a radio contrast agent
known as barium sulfate. Barium comes prepared in powder form.
|Synapse||Synapse definition is – the point at which a nervous impulse passes|
from one neuron to another.
|Tachycardia||Tachycardia is a relatively rapid heart action whether physiological|
(as after exercise) or pathological.
|Total prenanteral nutrition (TPN)||Parenteral nutrition (PN) is feeding a person intravenously, bypassing|
the usual process of eating and digestion. The person receives
nutritional formulae that contain nutrients such as glucose, amino
acids, lipids and added vitamins and dietary minerals. It is called
total parenteral nutrition (TPN) or total nutrient admixture (TNA)
when no significant nutrition is obtained by other routes.
|Toxicity||Toxicity is often a relative thing; in the words of a famous old|
saying, “The dose makes the poison”. Thus, it’s possible to die from
drinking too much water, and lives have been saved by tiny doses of
arsenic. Even though botulinum toxin is the most toxic substance
known, it’s the basic ingredient in Botox, which is injected into the
face to get rid of wrinkles. With some poisons, mere skin contact can
be lethal; others are lethal when breathed into the lungs in
microscopic amounts. To determine if a chemical will be officially
called a poison, researchers often use the “LD50” test: If 50
milligrams of the substance for every kilogram of an animal’s body
weight results in the death of 50% of test animals, the chemical is a
poison. But there are problems with such tests, and toxicity remains a
very individual concept.
|Toxins||Toxins are a poisonous substance that is a specific product of the|
metabolic activities of a living organism and is usually very
unstable, notably toxic when introduced into the tissues, and
typically capable of inducing antibody formation.
|Transcutaneous electrical nerve stimulations therapy (TENS)||Transcutaneous electrical nerve stimulation is the use of electric|
current produced by a device to stimulate the nerves for therapeutic
purposes. TENS, by definition, covers the complete range of
transcutaneously applied currents used for nerve excitation although
the term is often used with a more restrictive intent, namely to
describe the kind of pulses produced by portable stimulators used to
treat pain. The unit is usually connected to the skin using two or
more electrodes. A typical battery-operated TENS unit is able to
modulate pulse width, frequency and intensity. Generally TENS is
applied at high frequency with an intensity below motor contraction or
low frequency with an intensity that produces motor contraction. While
the use of TENS has proved effective in clinical studies, there is
controversy over which conditions the device should be used to treat.
|Treatment for catabolism in patients with mitochondrial diseases||Once a patient is already in a catabolic state, treatment should begin|
immediately. This treatment includes: – Stop the oral intake of a
toxic compound, including any applicable medications (usually by
making the patient NPO) – Provide IV fluids with dextrose – Give IV
fluids at a higher than maintenance rate – Insulin may be needed, not
only to prevent hyperglycemia but also to provide the body with a
hormonal signal to stop catabolism – Monitor routine chemistries,
glucose, ammonia, ketones and liver function for metabolic
derangements – Correct any metabolic derangements: (1) Hypoglycemia –
if hypoglycemic, administer 1-2 g/kg of glucose IV STAT; follow with
(at least) a 10% glucose solution; (2) Metabolic acidosis – administer
NaHCO3 as a bolus (1 mEq/kg) if acutely acidotic with pH < 7.22 or
bicarb level < 14, followed by a continuous infusion. (3) Hyperammonemia – the elevated ammonia reflects a secondary inhibition of the urea cycle. As treatment for the metabolic decompensation proceeds, the ammonia level should diminish. A level > 200 may require
treatment. – – Provide medications such as IV levo-carnitine (100
mg/kg/day, divided tid) to facilitate the removal of toxic metabolic
species – Treat any underlying infection and fever.
|Urinary retension||Urinary retention is an inability to completely empty the bladder.|
Onset can be sudden or gradual. When of sudden onset, symptoms include
an inability to urinate and lower abdominal pain.
|Vagal nerve stimulators (VNS)||Vagal nerve stimulators (VNS) are devices that stimulate the vagus|
nerve. They can be used for a variety of medical reasons. (1) They can
be used to treat epilepsy and seizures. (2) VNS have been proven to
ease Rheumatoid Arthritis. The study, of 17 adults with the painful
autoimmune disease, tested the effects of vagus nerve stimulation — a
technique long used to control seizures in some people with epilepsy.
It found that over six weeks, most of the patients showed some
improvements in joint swelling. (3) Electrical stimulation of the
vagus nerve has been shown to be helpful for chronic depression,
controlling intractable epileptic seizures, and now, when coupled with
sound therapy, has the potential to reduce noise levels in those with
tinnitus. (4) Vagus nerve stimulation (VNS) is a surgical procedure
that can be used to treat those with treatment-resistant depression. A
pacemaker-like device, implanted in the body, is attached to a
stimulating wire that is threaded along a nerve called the vagus
nerve. The vagus nerve travels up the neck to the brain, where it
connects to areas believed to be involved in regulating mood. Once
implanted, this device delivers regular electrical impulses to the
vagus nerve. (5) This non-invasive, FDA-cleared treatment option
decreases the likelihood of headaches. Recent clinical trials have
been evaluating vagus nerve stimulation (VNS) for the treatment of
various headache conditions, including migraine and cluster headaches.
In November 2018, the FDA cleared the VNS device for treatment of
|Valproic acid||Valproic acid is a synthetic crystalline compound with anticonvulsant|
properties, used (generally as salts) in the treatment of
epilepsy. Valproic acid is one of the medications that should generally
be avoided during times of illness in individuals with mitochondrial
disease. If valproic acid (valproate) be used for the first time
during an acute mitochondrial illness, liver enzymes, ammonia and
synthetic live function should be closely monitored.
|X-linked gene inheritance||Genes are inherited from our biological parents in specific ways. One|
of the basic patterns of inheritance of our genes is called X-linked
inheritance. X-linked gene inheritance means that the gene causing the
trait or the disorder is located on the X chromosome.
