To the group: But in light of previous postings, might it be that he was given Demerol at the time of the trauma? Health-care workers seeing a pain-reliever might well administer Demerol. If indeed a Demerol-Eldeprel interaction took place, it might indeed be the cause of the subsequent PD. Food-drug and drug-drug interactions are my personal soapbox, however, and I tend to jump on it at the slightest provocation. As a registered dietitian, I've seen too many people misdiagnosed with Alzheimer's and Parkinson's who were deficient in B12 or using powerful drug combinations. So I might not be completely objective! Best regards,
