Physical activity, nutrition and cognitively stimulating activities are all known to be good ways to prevent Alzheimer’s disease and dementia. And older adults at risk can access a variety of lifestyle services to that end, including diet regimes and exercises for their body and mind.
Now an international team of researchers led by Université de Montréal psychology professor Sylvie Belleville has determined how many of those intervention sessions are needed prevent cognitive decline in people at risk: only about a dozen.
Published in Alzheimer’s & Dementia : The Journal of the Alzheimer’s Association, the study by Dr. Belleville and colleagues at the universities of Toulouse and Helsinki show that 12 to 14 sessions are all that’s were needed to observe an improvement in cognition. Until now, the number of sessions or “doses” needed for optimal effect has been unknown.
