Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 60 years or older with type 2 diabetes and a Mini-Mental State Examination score between 24 and 28.

Probably not a fit

Patients with type 1 diabetes, severe cognitive impairment, or other significant medical conditions may not benefit from this study.

What this trial studies

This exploratory pilot study evaluates the cognitive improvement effects of a combination therapy using cilostazol and ginkgo biloba extract in elderly patients diagnosed with type 2 diabetes mellitus. The study aims to determine if this combination can enhance cerebral blood flow and provide neuroprotection, potentially preventing cognitive decline. Participants will receive either the active treatment or a placebo, and their cognitive abilities will be assessed using standardized measures. The findings may lay the groundwork for future therapeutic strategies targeting cognitive impairment in this population.

Why it matters

Potential benefit: If successful, this study could lead to new preventive strategies for cognitive decline in elderly patients with type 2 diabetes.

How similar studies have gone: While the combination of cilostazol and ginkgo biloba has shown potential benefits individually, this specific combination approach is novel and has not been extensively tested in prior studies.
