This population-based retrospective cohort study aimed to evaluate the appropriateness of antiplatelet therapy use among older adults with all-cause dementia and across different dementia subtypes. Medical records of patients aged 65 years and older who were evaluated at a tertiary-level geriatric outpatient clinic were reviewed. Dementia subtypes were classified according to internationally accepted diagnostic criteria. Patterns of antiplatelet use were assessed in accordance with current guideline recommendations. The study sought to determine the appropriateness of antiplatelet use across dementia subtypes and to describe real-world prescribing practices in this population.

Inclusion Criteria:

• Age 65 years and older.
• Diagnosis of dementia based on internationally accepted diagnostic criteria.
• Evaluation at a tertiary-level geriatric outpatient clinic.

Exclusion Criteria:

• Patients with incomplete or inaccessible medical records.
• Individuals with missing data on antiplatelet therapy use.

The study population consists of older adults aged 65 years and older with a diagnosis of dementia who were evaluated in a tertiary-level geriatric outpatient clinic.
