Dementia and depression after stroke
Journal Title: Rehabilitacja Medyczna - Year 2014, Vol 18, Issue 1
Abstract
Introduction: In addition to physical impairment, post-stroke patients also display emotional and cognitive disorders, e.g., depression and dementia, which may result from a stroke or occur independently of it. Because these disorders affect treatment outcome, the risk of a subsequent stroke, and mortality, they should be taken into account during rehabilitation.Aim: The aim of this study was to assess the prevalence of depression and dementia among post-stroke patients and to assess the correlation between these disorders and sociodemographic and clinical characteristics.Material and methods: Retrospective analysis of medical documentation of 124 post‑stroke patients hospitalised in a neurological rehabilitation ward from 1 January 2012 to 31 July 2013 was conducted. Depression and dementia were diagnosed by psychologists using the Mini-Mental State Examination, Short Test of Mental State, Hamilton Rating Scale for Depression, and Beck Depression Inventory.Results: a total of 46% of post-stroke patients rehabilitated in the Krzeszowice Rehabilitation Centre were diagnosed with dementia, and 39% were diagnosed with depression. Persons aged over 65 years had a higher chance of dementia compared to younger persons (OR=5.91, 95%CI: 2.52–13.89). Aphasia correlated with a five times higher chance of dementia (OR=5.74, 95%CI: 1.93–17.11). Sex, education, and other analysed clinical and sociodemographic characteristics did not correlate with dementia. No correlation was found between depression and dementia, age, sex, education, number of inhabitants, the type, location and number of strokes, time since stroke, hypertension, diabetes, or aphasia.Conclusions: Dementia and depression were diagnosed in a group of post-stroke patients. Dementia was more prevalent among persons aged over 65 years and persons with aphasia. Because depression and dementia increase the risk of a subsequent stroke and mortality in post-stroke patients, both disorders should be diagnosed and treated early to prevent their effects.
