Abstract:
The aim of this 4-year follow-up study was to find out how often dementia appears after stroke in unselected material. All patients younger than 65 years (52) still alive 4 years after stroke in a stroke register (total 255 patients) were studied neurologically and neuropsychologically. Three patients with brain infarction filled the criteria for mild dementia. This is more than was to be expected. All 3 demented patients could be classified as multi-infarct dementia. The findings concerning dementia are discussed.
Insights
Dementia frequently develops after stroke, particularly multi-infarct dementia. This study tracked dementia incidence in younger stroke survivors over four years, finding a higher-than-expected rate.
Area of Science:
- Neurology
- Neuropsychology
- Geriatrics
Background:
- Stroke is a leading cause of disability.
- Dementia is a potential long-term consequence of stroke.
- Understanding post-stroke dementia incidence is crucial for patient care.
Purpose of the Study:
- To determine the incidence of dementia following stroke in an unselected population.
- To investigate the types of dementia observed after stroke.
- To assess dementia development in younger stroke survivors (under 65 years) over a 4-year period.
Main Methods:
- A 4-year follow-up study of patients from a stroke register.
- Neurological and neuropsychological assessments were performed on surviving patients younger than 65.
- Patients were evaluated for dementia criteria.
Main Results:
- Three out of 52 surviving patients younger than 65 years met criteria for mild dementia.
- The observed incidence of dementia was higher than anticipated.
- All three dementia cases were classified as multi-infarct dementia.
Conclusions:
- Stroke, particularly in younger individuals, carries a significant risk of developing dementia.
- Multi-infarct dementia is a notable outcome following stroke.
- Further research is warranted to explore the mechanisms and prevention of post-stroke dementia.
