Insights
Post-stroke dementia (PSD) affects 30.2% of stroke survivors. Key risk factors include older age, atrial fibrillation, and initial cognitive and functional status, highlighting the need for early intervention.
Area of Science:
- Neurology
- Geriatrics
- Public Health
Context:
- Stroke is a leading cause of disability worldwide.
- Post-stroke dementia (PSD) is a significant complication, impacting patient quality of life and increasing societal burden.
- Understanding the prevalence and risk factors of PSD is crucial for effective management.
Purpose:
- To determine the prevalence of post-stroke dementia (PSD) 3 months after stroke.
- To identify clinical and sociodemographic risk factors associated with PSD development.
Summary:
- A study of 106 stroke patients found that 30.2% developed PSD within 3 months.
- Predictive factors for PSD included advanced age, atrial fibrillation, multiple brain lesions, and poorer cognitive and functional status at hospitalization.
- These findings underscore the commonality of PSD and the importance of early risk factor assessment.
Impact:
- Early identification and management of PSD risk factors can mitigate the long-term consequences of stroke.
- Reducing PSD prevalence can improve patient quality of life and lessen the societal impact of stroke.
- This research provides valuable data for healthcare providers in stroke rehabilitation and dementia care settings.
Objective:
The aim of this study was to determine the prevalence of post-stroke dementia (PSD) and its possible clinical and sociodemographic risk factors 3 months after the index stroke episode.
Methods:
Among 147 patients who were hospitalized in the inpatient neurology clinic of Dicle University Faculty of Medicine with a diagnosis of stroke, 106 that met the inclusion criteria were included in the study 3 months after the index stroke. All patients underwent a detailed systemic and neurological examination, as well as a clinical interview in an effort to determine the sociodemographic features, and both vascular and non-vascular risk factors of stroke. Routine laboratory examinations and cranial imaging (computed tomography [CT] or magnetic resonance imaging [MRI]) were also conducted. The functional, clinical, and cognitive status of the patients were evaluated at the time of hospitalization and 3 months later with the Barthel Index, NIH Stroke Scale (NIHSS), and Mini Mental State Examination (MMSE), respectively.
Results:
Of the 106 patients included in the study, 32 (30.2%) were diagnosed with PSD. Multivariate analyses revealed that increased age, presence of atrial fibrillation, multiple brain lesions, and cognitive and functional status during hospitalization predicted the development of PSD in this group of patients.
Conclusion:
The results corroborate previous findings that PSD is a common complication of stroke. Early recognition and treatment of PSD risk factors will definitely diminish the burden of stroke on society and help to improve patient quality of life.
