10 Signs of Parkinson's Disease You're Most Likely to Ignore
Loss of sense of smell
This is one of the oddest, least-known, and often earliest signs of Parkinson's disease, but it almost always goes unrecognized until later. "Patients say they were at a party and everyone was remarking on how strong a woman's perfume was, and they couldn't smell it," says Illinois neurologist Michael Rezak, who directs the American Parkinson's Disease Association National Young Onset Center. Along with loss of smell may come loss of taste, because the two senses overlap so much.
