Summary
Late-onset epilepsy, beginning after age 25, affects 25% of epilepsy patients. Common causes include alcoholism and stroke, with standard medications effectively controlling most cases.
Area of Science:
- Neurology
- Epileptology
Context:
- Late-onset epilepsy (LOE) is defined as epilepsy beginning in adulthood (after age 25).
- Approximately 25% of all epilepsy cases present after age 25, with incidence increasing with age.
- LOE presents unique etiological and diagnostic challenges compared to epilepsy in younger populations.
Purpose:
- To revise the current understanding of late-onset epilepsy.
- To outline the primary etiologies and diagnostic approaches for LOE.
- To evaluate the efficacy of common antiepileptic drugs in LOE.
Summary:
- Key etiologies for LOE include alcoholism (22%), stroke (18%), brain tumors (10%), and metabolic disturbances (10%).
- Diagnosis requires comprehensive clinical assessment, cardiovascular evaluation, metabolic tests, electroencephalography (EEG), and neuroimaging.
- Monotherapy with phenobarbital, carbamazepine, or valproate achieves seizure control in 80% of LOE patients.
Impact:
- This review provides a consolidated perspective on LOE, aiding clinicians in diagnosis and management.
- Identifying specific etiologies can guide targeted treatment strategies for LOE.
- Understanding treatment efficacy highlights the importance of addressing underlying cerebral damage in refractory cases.
