Prevalence of Dementia and its Correlation with Cognitive Function in Elderly Post-Stroke Patients

BACKGROUND: Post-stroke dementia (PSD) is a clinical entity that encompasses all types of dementia following an index stroke, which may affect up to one third of stroke survivors. Unlike physical disability after stroke, cognitive function usually worsens over time and are often overlooked with detrimental impacts on the quality of life of survivors. MATERIALS AND METHOD: This work is a cross-sectional questionnaire-based study. Elderly post-stroke patients participated in this study. We adopted Dementia Severity Rating Scale (DSRS) and The Mini Mental State Examination (MMSE) we recorded the prevalence of dementia and its correlation with cognitive function in elderly post stroke patients. RESULT: Data of 46 participants was analysed. The mean age group was above 60years, as this study was conducted in elderly post-stroke patients. In this study 41% females and 59% males participated based on the inclusion and exclusion criteria. Two components were collected using Dementia Severity Rating Scale (DSRS) and The Mini Mental State Examination (MMSE). CONCLUSION: The study concluded that in present scenario of post stroke patient. the sub items of questionnaire (MMSE) and (DSRS) have increased values indicating towards risk factor of dementia and cognitive functions in post-stroke elderly patients in Pravara Rural Hospital is mostly when the age increases as shown significant correlation in Group B with age group of 60-70 years. whereas in Group A with age group of 71-80 years shows that there is no significant correlation. Hence, our study concluded that there is a co-relation of dementia and cognitive function in elderly post stroke patients. So, it determines that the correlation between dementia and cognitive function is more significant at age 71-80 hence, statistically proved.
