Class of substances that damage neurons through paroxysmal overactivity. The best known excitotoxins are the excitatory amino acids, that can produce lesions in the CNS similar to those of Huntington\'s chorea or Alzheimer\'s disease. Excitotoxicity is thought to contribute to neuronal cell death associated with stroke.
