Role of excitotoxicity in human neurological disease.

Author information

Massachusetts General Hospital, Boston.


An increasing body of evidence has implicated excitoxicity as a mechanism of neuronal death in both acute and chronic neurological diseases. A major recent advance has been the successful cloning and expression of the non-NMDA, NMDA, and metabotropic glutamate receptors. The cellular mechanisms responsible for cell death following activation of these receptors are still being clarified. A recent advance in conceptualizing excitotoxicity is the notion that a slow excitotoxic process may occur as a consequence of either a receptor abnormality or an impairment of energy metabolism. It is possible that such a mechanism may occur in neurodegenerative illnesses. Recent therapeutic studies have focused on glycine site antagonists and on the efficacy of non-NMDA antagonists in ischemia.
