#Cognitive Activity and Onset Age of Incident #Alzheimer Disease #Dementia

To test the hypothesis that higher level of cognitive activity predicts older age of dementia onset in Alzheimer's disease (AD) dementia. Methods: As part of a longitudinal cohort study, 1,903 older persons without dementia at enrollment reported their frequency of participation in cognitively stimulating activities. They had annual clinical evaluations to diagnose dementia and AD, …

#Dementia risks identified by vocal features via #telephone conversations: A novel machine learning prediction model

Due to difficulty in early diagnosis of Alzheimer’s disease (AD) related to cost and differentiated capability, it is necessary to identify low-cost, accessible, and reliable tools for identifying AD risk in the preclinical stage. We hypothesized that cognitive ability, as expressed in the vocal features in daily conversation, is associated with AD progression. Thus, we …
