In a new study published by Alzheimer’s & Dementia, scientists from Rush University and Tufts University were the first to compare cognitive decline factors to vitamin D concentrations not only in the blood, but in the brain as well.
Researchers analyzed participants of the Rush Memory and Aging Project (MAP)—an ongoing longitudinal study that aims to identify risk factors for Alzheimer’s disease and other cognitive decline disorders—before and after death to see how their vitamin D levels impacted cognitive function in their later years.
Free of known dementia at the time of enrollment, all MAP participants agreed to participate in annual evaluations and organ donation when they died. In this study, the average age of participants was 92 at the time of death.
