Scientists at the Douglas Mental Health University Institute, Centre for Addiction and Mental Health and University of Toronto have trained an artificial intelligence (AI) algorithm to accurately predict whether a person’s cognitive abilities are likely to lead to Alzheimer’s disease within five years. They designed the algorithm to learn from genetics, clinical data and magnetic resonance imaging (MRI) and trained it using data from more than 800 people who participated in the Alzheimer’s Disease Neuroimaging Initiative.
Researchers in Western Canada report that emotional exhaustion is on the rise among care aides working in nursing homes, and job satisfaction has not improved. The frequency of responsive behaviours experienced by care aides who work with residents living with dementia is also increasing.
Older adults who participate in dementia-prevention trials are most often motivated by altruism, according to researchers who conducted a Research Satisfaction Survey at 27 study sites in metropolitan areas in the United States. Respondents rated their overall satisfaction level as high, although they preferred interviews administered by staff rather than via automated technologies. They liked having an opportunity to volunteer and to challenge their cognitive abilities, but disliked repetitive assessments.
The odds of developing Alzheimer’s disease or a related dementia (ADRD) as an adult are higher for individuals who, as adolescents, demonstrate lower cognitive abilities in areas such as language and reasoning.
