Abstract
BackgroundCognitive impairment is an important aspect for stroke survivors. Little data are available about the frequency and risk factors of post-stroke dementia in Egypt.ObjectivesThe aim of this study is to evaluate the frequency and predictors of post-stroke dementia and its impact on outcome.MethodsA total of 380 patients with acute stroke were included. Patients were subjected to demographic data collection, neurological examination, and assessment of vascular risk factors. Furthermore, assessment of stroke severity by Barthel Index was done. After 6 months, patients were assessed for outcome and development of post-stroke dementia.ResultsPost-stroke dementia was detected in 20.8% of patient. It was recorded more in old ages, illiterates, unmarried, unemployed, and those with recurrent stroke and with cerebral infarction (significantly with cardio-embolic).ConclusionPost-stroke dementia is high in Egypt, especially in those with illiteracy, atrial fibrillation, brain atrophy, severe strokes, and those presented with hemiplegia, sphincter affection, abnormal gait, and psychotic features. Assessment for post-stroke dementia should be done during follow up of stroke patients.

Summary
Cerebrovascular stroke (CVS) is one of the leading causes of mortality and disability worldwide [1]. Post-stroke dementia (PSD) is the second most common cause of dementia [4] and one of the main causes of dependency in survivors [5]. About one-third of stroke survivors are found to have a significant degree of cognitive impairment within the first months after the event [6]. The prevalence of PSD in stroke survivors is about 30% and having a stroke doubles the risk of dementia [7]. The risk factors for PSD are multifactorial and. Cognitive impairment is an important aspect for stroke survivors. Little data are available about the frequency and risk factors of post-stroke dementia in Egypt
