Summary
Late-onset epilepsy in individuals over 50 is frequently linked to cerebrovascular disease and leukoaraiosis, particularly in older adults. Identifying the cause often requires further investigation, as some cases remain unknown initially.
Area of Science:
- Neurology
- Geriatrics
- Epidemiology
Background:
- Epilepsy in older adults presents unique etiological considerations.
- Understanding the specific causes and risk factors for late-onset epilepsy is crucial for effective management.
Purpose of the Study:
- To analyze the causes and seizure types in a cohort of 130 epilepsy patients over 50 years of age.
- To investigate the role of factors like cerebrovascular disease, leukoaraiosis, and other conditions in late-onset epilepsy.
Main Methods:
- Retrospective analysis of medical documentation and investigations of 130 epilepsy cases.
- Categorization of seizure types and identification of etiological factors.
Main Results:
- Partial seizures were most common (66.2%), followed by secondary generalization (33.8%).
- Cerebrovascular disease (50.8%) was the leading cause, especially in those over 74.
- Leukoaraiosis was a significant proepileptogenic factor in patients over 74 (56.5%).
- Alcohol-related craniocerebral trauma and neoplastic diseases were also identified causes.
- In 22.3% of cases, the epilepsy cause remained unknown, with some diagnoses made on follow-up.
Conclusions:
- Cerebrovascular disease and leukoaraiosis are key factors in late-onset epilepsy, particularly in the elderly.
- Thorough clinical examination and follow-up imaging are essential for diagnosing unknown epilepsy causes.
- Certain medications may also be implicated in seizure precipitation.
