Woman 'smelled' Parkinson’s on her husband years before diagnosis

Scottish woman Joy Milne's acute sense of smell helped detect Parkinson's disease in her husband years early. She has been with her husband, Les, since she was 16. In his early thirties, Joy noticed an unusual, musky odour coming from his shoulders and neck. When Les was diagnosed with Parkinson's at 45, the significance of this scent became clear.
