title: [Epilepsy in the elderly].
abstract: Although epilepsy was believed to have the highest incidence in childhood, recent epidemiologic studies revealed that the incidence increases markedly in elderly. At least 1% of elderly people are estimated to have epilepsy. Cerebrovascular disease is the most common underlying cause although 25% of new onset geriatric epilepsy cases have no obvious etiology. The most common seizure manifestation is atypical complex partial seizures with long-lasting postictal confusion which may lead to underdiagnosis and misdiagnosis. Factors complicating the treatment of geriatric epilepsy include comorbidities, drug interactions due to polytherapy, and aging-related changing of pharmacokinetics. Individualization of dosage and avoidance of unnecessary polypharmacy are essential for safe utilization of anti-epileptic drugs. New generation drugs such as gabapentin and levetiracetam are better tolerated for elderly people.
