MedPage Today (10/15, George) reported, “Signs of brain impairment appeared as early as nine years before people received a diagnosis for Alzheimer’s or other dementia-related diseases,” investigators concluded in a study that “assessed baseline cognitive and functional measures in 2,778 participants who subsequently developed Alzheimer’s, 2,370 who developed Parkinson’s, 211 who developed frontotemporal dementia,” 133 “who developed progressive supranuclear palsy,” 40 “who developed dementia with Lewy bodies,” and “73 who developed multiple system atrophy.” Next, the study team “compared these individuals against baseline data from 493,735 Biobank controls who were not diagnosed later with a neurodegenerative diagnosis.” The findings were published online in the journal Alzheimer’s & Dementia
