Earlier Diabetes Diagnosis May Be Associated with Dementia Risk: Study finds

People diagnosed with type 2 diabetes at a younger age are at a higher risk for developing dementia than those diagnosed later in life, according to a study led by researchers at the NYU Rory Meyers College of Nursing. The findings, published in PLOS ONE, show that the increased risk is especially pronounced among adults with obesity.
"Our study suggests that there may be cognitive consequences to earlier onset type 2 diabetes, and it points to the need for strategies to prevent dementia that consider both diabetes and obesity," said Xiang Qi, assistant professor at NYU Meyers and the study's first author.
To understand how the timing of a type 2 diabetes diagnosis relates to dementia risk, the research team analyzed data from 2002 to 2016 in the Health and Retirement Study, a longitudinal study conducted by the University of Michigan Institute for Social Research. The study included 1,213 U.S. adults aged 50 and over with type 2 diabetes confirmed by blood tests -- and no dementia upon joining the study. Following participants for up to 14 years, 216 (17.8%) developed dementia based on follow-up telephone interviews.
