Alphabetical list of currently known Human Neurological Conditions including short definitions for each disorder.
Neurological Disorders Main Document A neurological disorder is defined as any disorder of the body nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms.
Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain and altered levels of consciousness.
The specific causes of neurological problems vary, but can include genetic disorders, congenital abnormalities or disorders, infections, lifestyle or environmental health problems including malnutrition, and brain injury, spinal cord injury or nerve injury.
There are many recognized neurological disorders, some relatively common, but many rare. They may be assessed by neurological examination, and studied and treated within the specialties of neurology and clinical neuropsychology. Mental disorders, on the other hand, are "psychiatric illnesses" or diseases which appear primarily as abnormalities of thought, feeling or behavior, producing either distress or impairment of function.
Neurological disorders affect the brain as well as the nerves found throughout the human body and the spinal cord. These three parts of the body work together and are referred to as the central nervous system that control everything in the body.
Neurology is the medical science that deals with the nervous system and disorders that affect it. Conditions that are classed as mental disorders, or learning disabilities and forms of Intellectual disability, are not themselves usually dealt with as neurological disorders.
Neurological disorders can be categorized according to the primary location affected, the primary type of dysfunction involved, or the primary type of cause. The broadest division is between central nervous system disorders and peripheral nervous system disorders.
Neurological disorders can affect an entire neurological pathway or a single neuron. Even a small disturbance to a neuron's structural pathway can result in dysfunction.
According to the University of California, San Francisco, there are more than neurological disorders that strike millions each year. These diseases and disorders inflict great pain and suffering on millions of patients and their families, and cost the U. Social Security approves disability benefits for serious cases of epilepsy, cerebral palsy, Parkinson's disease, multiple sclerosis, ALS, and other nerve-based diseases.

Alphabetical glossary and definitions of medical terms and health conditions.
Children who are born without this membrane and also have other abnormalities, pituitary deficiencies and abnormal development of the optic disk have a disorder known as septo-optic dysplasia. Acid Lipase Disease - is a name used to describe two related disorders of fatty acid metabolism.
Acid lipase disease occurs when the enzyme needed to break down certain fats that are normally digested by the body is lacking or missing, resulting in the toxic buildup of these fats in the body's cells and tissues. These fatty substances, called lipids, include waxes, oils, and cholesterol.
Acid Maltase Deficiency - Glycogen storage disease type II also called Pompe disease or acid maltase deficiency is a rare genetic disorder caused by a deficiency in the enzyme acid alpha-glucosidase GAA EC 3.
Acquired Epileptiform Aphasia - Landau-Kleffner syndrome LKS is a rare, childhood neurological disorder characterized by the sudden or gradual development of aphasia the inability to understand or express language and an abnormal electro-encephalogram EEG. LKS affects the parts of the brain that control comprehension and speech.
The disorder usually occurs in children between the ages of 5 and 7 years. Acute Disseminated Encephalomyelitis - is an immune mediated disease of brain. It usually occurs following a viral infection or vaccination, but it may also appear spontaneously.
It is similar in some ways to multiple sclerosis, and is considered part of the Multiple sclerosis borderline. Adie's Pupil - is a neurological condition of unknown origin with an unusual, asymmetric presentation known as anisocoria, an inequality in the size of the pupils of the eyes.
It is believed to be a result of damage to the nerve innervating a muscle of the eye known as the ciliary body.A chromosome (/ ˈ k r oʊ m ə ˌ s oʊ m, -ˌ z oʊ m /; from Ancient Greek: χρωμόσωμα, chromosoma, chroma means colour, soma means body) is a DNA molecule with part or all of the genetic material of an monstermanfilm.com eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable.
Neurological disorders are medically defined as disorders that affect the brain as well as the nerves found throughout the human body and the spinal cord. Certain human diseases result from mutations in the genetic complement (genome) contained in the deoxyribonucleic acid (DNA) of chromosomes.
A gene is a discrete linear sequence of nucleotide bases (molecular units) of the DNA that codes for, or directs, the synthesis of a.
Genetic testing: Genetic testing, any of a group of procedures used to identify gene variations associated with health, disease, and ancestry and to diagnose inherited diseases and disorders. A genetic test is typically issued only after a medical history, a physical examination, and the construction of a family.
Childhood developmental disorders Developmental disorders of childhood are another large category of mental disorders caused by mutations, deletions, translocations (rearrangements of the arms of chromosomes) and other alterations in genes or chromosomes.
A Genetic Glossary Cells: The units that comprise living beings. The human body is made of about 60 trillion cells.
Nucleus: A membrane-bound structure inside cells that contains DNA. Chromosomes: DNA is packaged into units called chromosomes. Humans have 23 pairs of chromosomes, for a total of
