Camilla: << A study by the University of FLORIDA BRAIN INSTITUTE STATES THAT A BLOW TO THE HEAD CAN CAUSE DAMAGE FOR AS LONG AS A MONTH AFTERWARD---MUCH LONGER >> Camilla, Ted as a senior in college was hit on the head with a baseball and fracured his "head". After the hospital let him out with out doing anythng, it didn't look good in the paper so they put him back in and "straightened out" his forehead. I believe that was the start of his troubles since it was at the time penecillin was believed to be the panacea for infections and I suspect the operating room was not as sterile as it could have been. AFter that he had constant infections, colds, sinus infections, etc. After five years he had one so bad they had to go in and cut bone out or it would have gone into his brain. This was after an incompetent doctor only treated him with pain pills and he was not strong enough. I suspect there was a small virulent infection left. After another three years of infections, antibiotics, etc. he had a five hour operation which removed the outer bone structure so that an infection would not be "trapped". This was almost five hours of banging his head and was horrible. Many other things happened in the interim, however twice when coaching kids in baseball he was once again hit on the head. Then while riding his bicycle on a hot muggy day, he blanked out fell off (thankfully had a helmet on) and hit his head. This may have saved his life since it was ultimately felt it was due to an arythmic heart beat. About a year after that came the onset of Parkinson's. He may have gotten Parkinson's ultimately, but I believe it was the sum total of these incidents that caused it. Virginia Christiansen White Plains, NY [log in to unmask]
