Summary

Background

Post-stroke cognitive impairment and dementia are major public health problems.

Objectives

Construction of a cognitive assessment tool applicable to post-stroke dementia detection in the older population and suitable for both illiterate and educated Egyptians.

Methods

The new post-stroke Ain-Shams cognitive assessment (PSACA) test was scored out of 69 points. The validity and reliability of the PSACA test were assessed on a pilot sample of 30 older participants, comparing the test with the Mini-Mental State Examination (MMSE) test. Then a cross-sectional study for the detection of dementia was conducted recruiting 120 Egyptian older post-stroke participants aged 60years and over, from Ain-Shams University Hospital clinics.

Results

The mean age of the participants was 69.17 (±8.03). The test proved valid and reliable (Cronbach's Alpha was 0.72). The cutoff point of the PSACA test for post-stroke dementia diagnosis was≤54.5, with a sensitivity of 90% and a specificity of 78.7%.
