Type 2 diabetes mellitus (T2DM) has been linked with cognitive impairment and dementia. A new cross-sectional study reports that T2DM is also associated with dementia in Parkinson disease, and another study describes the long-term clinical course of diabetes-associated cognitive dysfunction; however, the mechanisms through which T2DM affects the brain are not completely understood.
