"A broad range of chronic neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's chorea, stroke (multi-infarct) dementia, amyotrophic lateral sclerosis and AIDS dementia are now believed to be caused, at least in part, by the excitotoxic action of glutamate/aspartate...Even the typical memory loss, confusion, and mild intellectual deterioration that frequently occurs in late middle age/old age may be caused by glutamate/aspartate excitotoxity...Acute diseases and medical conditions such as stroke brain damage, ischemic (reduced blood flow) brain damage, alcohol withdrawal syndrome, headaches, prolonged epileptic seizures, hypoglycemic brain damage, head trauma brain damage...are also believed to be caused, at least in part, by glutamate/aspartate excitotoxicity...Medical research is focusing more and more on ways to combat excitotoxicity. A drug called 'memantine' which blocks the main glutamate-excitotoxicity site in neurons – the NMDA glutamate receptor - has been used clinically in Germany...Yet the few available clinical or experimental excitotoxicity-blocking drugs so far discovered have significant side effect potential – they may block normal, essential glutamate neurotransmission, as well as excitotoxicity...In 1969, Dr. John Olney, a neuroscientist and neuropathologist...discovered that MSG also caused lesions of the various nuclei of the hypothalamus, a key brain region that controls secretion of hormones by the pituitary gland. They also found that the MSG-fed newborn mice became obese, were short in stature, and suffered multiple hormone deficiencies...Olney has continued to be a pioneer in excitotoxin research, and he coined the term 'excitotoxin' in the late 1970s to describe the neural damage that glutamate, aspartate, and other similar chemicals can cause...excitotoxin pioneer Olney has recently shown that there is a long, slow development of excitotoxic brain damage in Alzheimer's disease that occurs before the dramatic Alzheimer's symptoms of memory loss, disorientation, cognitive impairment, and emotional lability arise...So you must not assume that just because you don't notice any obvious symptoms when you consume MSG/aspartame -containing foods, there is no excitotoxic damage occurring...Only one book has tried to alert the public to the details of how excitotoxins gradually (or sometimes suddenly) destroy our brains: Blaylock's 1994/1997 Excitotoxins...This article has barely scratched the surface of excitotoxins and their role in our lives. The interested reader is strongly urged to read Blaylock's book. It is written by a neurosurgeon, is highly readable and understandable..."
