Objective: To study the prevalence of dementia and related cognitive disorders in patients with stroke followed up at internal medicine and neurology outpatient clinics and to study its associating factors. Materials and Methods: The retrospective cross sectional cohort study was conducted in 98 patients with ischemic stroke, which has undergone cognitive assessments via Mini-mental status examination: Thai version (MMSE – Thai 2002) and Montreal cognitive assessment (MoCA). The diagnosis of cognitive disorders was based on these neuropsychological scores. Results: In 98 patients with ischemic stroke studied, the overall prevalence of vascular dementia (VAD) was 30.61%. Dementia was significant was associated with older patients (OR=1.06; 95%CI, 1.02-1.11; P<0.01) and hypertension (OR=3.55; 95%CI, 1.11-11.36; P=0.03). In the multivariate analysis, hypertension was not statistically significant (adjusted for age) (OR=2.64; 95%CI, 0.78-8.88; P=0.12). Conclusion: The prevalence of dementia in internal medicine and neurology outpatient clinic was about one-third. There is no statistically significant difference in clinical and neuroimaging characteristics between stroke patients with and without dementia, which should be further studied.
