Diabetes Medication Linked to Lower Dementia Risk in Psychiatric Patients
New research suggests SGLT2 inhibitors may lower dementia risk and reduce emergency psychiatric visits for older adults with mood and psychotic disorders.
SGLT2 Inhibitors and Cognitive Protection
Recent findings from a target trial emulation study indicate that SGLT2 inhibitors, a class of medication traditionally prescribed for diabetes, may offer significant cognitive benefits for older adults living with severe mental health conditions. By focusing on patients diagnosed with major depression, bipolar disorder, or schizophrenia, researchers identified a connection between these drugs and a decreased likelihood of developing all-cause dementia.
Dr. Jaime Ramos-Cejudo of the NYU Grossman School of Medicine led the investigation, which utilized data from the Department of Veterans Affairs healthcare system spanning 2016 to 2024. The study highlights a crucial demographic—those with psychiatric disorders—who are statistically more prone to dementia but frequently omitted from preventative neurological research.
Data Insights and Clinical Outcomes
The study involved 112,725 participants with a median age of 74.1 years. Within this cohort, 86.9% were diagnosed with major depressive disorder. Over a median follow-up period of 3.3 years, 4.1% of the participants received a dementia diagnosis. The intention-to-treat analysis revealed that patients using SGLT2 inhibitors experienced an odds ratio of 0.61 for all-cause dementia compared to those who did not use the medication. Furthermore, these patients saw a reduction in psychiatric emergency department visits, with an odds ratio of 0.80.
In a per-protocol analysis, sustained use of the medication showed even stronger associations, with an odds ratio of 0.54 for dementia and 0.56 for psychiatric hospitalizations. These findings suggest that the metabolic pathways influenced by SGLT2 inhibitors—specifically those involving mitochondrial function, inflammation, and energy metabolism—may play a protective role in the brain.
Metabolic Pathways and Brain Health
Dr. Ramos-Cejudo emphasizes that SGLT2 inhibitors possess unique properties compared to other antidiabetic drugs, primarily their ability to induce ketogenesis. This metabolic shift is particularly relevant given recent interest in ketogenic diets for psychiatric symptom management. The medication may provide a pharmacological pathway to achieve similar neurological stabilization.
While the results are promising, the research team noted certain limitations. The study population was predominantly male, which may impact how these findings apply to the broader population. Additionally, because the study relied on ICD codes and medical records, there remains a possibility of residual confounding regarding the baseline severity of psychiatric illnesses or pre-existing cognitive function.

Frequently Asked Questions
What specific psychiatric conditions were included in the study?
The study focused on older adults diagnosed with major depressive disorder, bipolar disorder, or schizophrenia spectrum disorder. These groups were selected due to their statistically higher risk for developing dementia.
How do SGLT2 inhibitors potentially protect the brain?
These drugs induce ketogenesis, which helps optimize brain energy metabolism and reduces inflammation. By targeting these biological pathways, the medication may help mitigate the neurodegenerative processes associated with dementia.
Does this study prove that diabetes drugs prevent dementia?
While the study shows a strong correlation between SGLT2 inhibitor use and lower dementia rates, it is an observational trial emulation. Further clinical trials are necessary to confirm these findings and establish a direct causal relationship.
