Speculations on disease states induced by excitatory amino acids.
There is much current interest in excitatory amino acids and their receptors because of their postulated involvement in several disorders of the nervous system. They function as neurotransmitters, but can act as neurotoxins in some situations. They have been implicated in the pathogenesis of cerebral hypoxic/ischemic and hypoglycemic damage, in epilepsy, in some degenerative diseases, and in so...

متن کاملExcitatory amino acids and Parkinson's disease.
SIR: Recently, Klockgether and Turski proposed that antagonists of excitatory amino acids may be beneficial in the treatment of Parkinson's disease 1. This suggestion , previously put torward by others 2-4, is supported by recent findings of animal experiments as weil as by clinical data. On the basis of these findings, a somewhat different conclusion can be drawn about the role of gluta-mate i...
متن کاملExcitatory amino acids and Alzheimer's disease.
Excitatory amino acids (EAA) such as glutamate and aspartate are major transmitters of the cerebral cortex and hippocampus, and EAA mechanisms appear to play a role in learning and memory. Anatomical and biochemical evidence suggests that there is both pre- and postsynaptic disruption of EAA pathways in Alzheimer's disease. Dysfunction of EAA pathways could play a role in the clinical manifesta...
متن کاملA Role for Excitatory Amino Acids in Diabetic Eye Disease
Diabetic retinopathy is a leading cause of vision loss. The primary clinical hallmarks are vascular changes that appear to contribute to the loss of sight. In a number of neurodegenerative disorders there is an appreciation that increased levels of excitatory amino acids are excitotoxic. The primary amino acid responsible appears to be the neurotransmitter glutamate. This review examines the na...
