Effective screening is carried out routinely for diabetic retinopathy, neuropathy, and nephropathy. Of late, studies have reported that cognitive decline can occur in people with diabetes, which could go undetected for a long period, and hence routine screening could be warranted.

Seventy patients with type 2 diabetes mellitus were included in the study. Patients with MoCA scores ≥26 were considered to have normal cognition (NC) and those with
