Aims To explore temporal patterns of change in cognitive impairments during the 2 years following stroke and to identify factors that affect these temporal changes. Background Despite the prognostic importance, temporal changes in post‐stroke cognitive impairment have not been systematically investigated. Design A non‐experimental, prospective, longitudinal descriptive study design. Methods Fifty‐two stroke patients were enrolled. Data were collected from April 2015 to September 2017. Cognitive function was evaluated at 5 different times (immediately, and at 3, 6, 12, and 24 months post‐stroke). Results Significant changes in cognitive function following stroke exhibited an “s‐shaped” curve, and the most rapid changes were observed between 3 and 6 months after stroke. The incidence of post‐stroke cognitive impairment ranged from 23.1% to 42.3% and was highest at 3 months and lowest at 6 months. Gender, educational level, pre‐stroke cognitive and functional abilities, haematoma, and brain surgery were associated with incidence of post‐stroke cognitive impairment. Conclusions The ongoing changes exhibited by patterns of cognitive impairment provide evidence that consistent efforts are required to achieve positive changes in post‐stroke cognitive function. Our findings may be helpful to develop nursing care strategies aimed at improving cognitive ability and consequently the quality of life of stroke patients.
