Diabetes duration and severity associated with brain atrophy

A study involving 614 patients with type 2 diabetes (mean age 62) has found that longer duration of diabetes was associated with more brain volume loss, particularly in the gray matter. Roughly, for every 10 years of diabetes, the brain was similar to that of a non-diabetic person who was two years older.

However, the study did not confirm any association of diabetes characteristics with small vessel ischemic disease.
