Stroke is the second leading cause of death in the world. It is often associated with various long-term physical and neuropsychological consequences. The aim of this article is to present the results of research on the occurrence of dementia and post-stroke depression. Using the keywords: post-stroke dementia, post-stroke depression, post-stroke cognitive impairment, stroke, Polish and foreign bibliographic databases were searched: PubMed, Science Direct, Wiley, Google Scholar. Documents that met the eligibility criteria were selected for inclusion in this review. After the conducted analyses, 7 Polish articles and 13 English-language articles were qualified for the review. In the group of people after stroke, there is an increased risk of depression and dementia. According to the data, up to every third person can deal with one of these neuropsychiatric disorders. The presented research analyses indicate that the results obtained by the respondents, at any time after the stroke, indicate the presence of mild cognitive impairment or slight degree dementia among the majority of respondents. It was also shown that people with a stroke in the dominant hemisphere are more likely to experience post-stroke depression. Depression and post-stroke dementia are a common and significant complication of stroke that negatively affects the functional outcome. The huge focus on neuropsychiatric disorders occurring after stroke in modern research is very important because of their negative impact on recovery, quality of life and survival after stroke.
