Drug-Induced Parkinsons

Honestly, I did not know that there was such a thing as drug-induced Parkinson's disease. I really don't know much at all about Parkinson's, but as I was thumbing through a book, The Complete Encyclopedia of Natural Healing by Gary Null, PhD, I came across a section about Parkinson's. Page 402 states that "older adults commonly develop drug-induced Parkinson's disease after having been prescribed antipsychotic durgs, such as Haldol, Thorazine, Mellaril and Stelazine. These antipsychotics are used to sedate nursing home patients with dementia and chronic anxiety, two nonpsychotic disorders. When these drugs are discontinued, most newly diagnosed Parkinson's patients return to normal." It also notes that commonly used pesticides are also linked to Parkinson's.

I find this information interesting and have to wonder if there might be other drugs or toxins that might be causeing Parkinson's disease.
