Type 2 diabetes and cortical thickness in older Mexican Americans and non‐Hispanic Whites

Type 2 diabetes mellitus (T2DM) at midlife increases dementia risk. Metabolic factors contribute more to Alzheimer’s disease (AD) risk in Mexican Americans (MA) than in non‐Hispanic Whites (NHW). However, most work relating T2DM to brain structure in older adults has been performed in NHWs. We evaluated how T2DM related to regional cortical thickness in cognitively intact older MA or NHW adults. We hypothesized that T2DM would relate more to regional cortical thickness in MA.
