Vassilaki M, Syrjanen MS, Kremers WK, et al. - Via performing a cohort study involving 3,460 participants (including 104 medical doctors [MDs]), aged ≥ 70 years, of the population-based Mayo Clinic Study of Aging, researchers determined the correlation between being an MD and the risk of incident dementia. Cognitive evaluations were performed in participants at baseline and approximately every 15 months to assess for diagnosis of dementia. MDs were older relative to the general population and were mostly males (93.3%). The researchers identified no significantly different risk for incident dementia in MDs without dementia at baseline vs the general population. Although there was a small number of older, mainly male, MDs, this study presents a preliminary insight on cognitive health later in life in MDs, while most previous studies examine the health of younger MDs.
