Although various neurological diseases occur in patients with inborn error of metabolism of amino acids, amino acids also act as neurotransmitters. Glutamic acid, aspartic acid and glycine play roles as an excitatory neurotransmitter, but exert a neurodegenerative effect in case of the excessive release. Extensive studies have recently been performed on glutamate receptors, especially N-methyl-D-aspartate (NMDA) receptor in the hippocampus. Alzheimer brain shows a decreased number of NMDA receptors in the frontal cortex. The parkinsonian changes caused by MPTP is abolished by the administration of a NMDA antagonist. gamma-Aminobutyric acid (GABA) acts as an inhibitory amino acid. The content of GABA is low in the striatum of patients with Huntington's disease. The number of NMDA receptor is decreased also in Huntington striatum. These observations may give a clue for the prevention of various neurodegenerative diseases.

UI	MeSH Term	Description	Entries
D010300	Parkinson Disease	A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

D006816	Huntington Disease	A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea.

D000544	Alzheimer Disease	A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.
