Dear Tom! Sorry to hear about the injury on duty! It is possible that Parkinson's Disease can follow head injury, if substantia nigra, a part of the brain where dopamin are produced, is injured. I found articals about the subject on pubmed's medline, an easy to use medical database. With Yahoo, search for: pubmed medline In pubmed's medline search for: parkinson accidental cerebral I think you find one artical. The press the button: find similar articals (or something like that). More then 100 articals will appair, but most of them are not interesting, but some are! If you need help with the professional medical languge, just ask me or the list! I ffound an interesting case from 1985. On pubmed's medline also search for:parkinson head injury Try to search other words from your hospital record. I am a male hospital nurse/perfusionist living in Copenhagen on medical treatment for PD for 18 months. I did also try to find the reason to my PD; but could not find anything. And even if you find a reason it might be very dificult to prove a connection to Parkinson's disease. In stead of looking backwards, I try to look forvard to find new possibilities with my life. But it is important to find out as much as possible about you parkinson, it is something we all have done, before we started to look forvard. I wish you welcome to the list and all the best for the future. If you think I can help, please ask!
