Type 2 diabetes mellitus (T2DM) is a global disease that poses a significant threat to public health. The incidence of both diabetes and dementia has increased simultaneously. Researchers have found that a large proportion of dementia patients have T2DM. In recent years, increasing evidence has demonstrated a link between cognitive decline and T2DM. Although the exact pathogenesis of cognitive impairment in T2DM is still unknown, current studies suggest that hyperglycemia, cerebrovascular disease, brain insulin resistance, and changes in gamma-aminobutyric acid (GABAergic) neurons may mediate the association between T2DM and cognitive impairment. These potential mechanisms may become targets for the treatment of cognitive disorders in patients with T2DM. Glucagon-like peptide-1 (GLP-1), a widely used anti-diabetic drug, has been shown to not only effectively lower blood glucose but also improve neurological function. Previous research has confirmed that GLP-1 and its analogues are effective in the treatment of cognitive impairment in patients with T2DM. This review describes current evidence on the mechanisms underlying the association between T2DM and cognitive impairment. In particular, this review focuses on recent advances in GLP-1 and its analogues for the treatment of T2DM-related cognitive impairment.
