Epilepsy in the elderly: Some clinical and pharmacotherapeutic aspects

The majority of epileptic seizures and epilepsies are no longer manifested in childhood and adolescence; instead their incidence is higher at the age of 65 years or older than during the first two decades of life. After cerebrovascular disorders and dementias, epileptic seizures and epilepsies now constitute the third most frequent neurologic problem encountered in the elderly. Important clinical features of epilepsy in the elderly related to the diagnosis include the most common seizure types and causes. Special features of drug treatment for epilepsy in the elderly result not only from the physiologic changes in the elderly but also from the particular pharmacology of the respective drugs. Because elderly patients very often require other long-term medication in addition to antiepileptic therapy, drug interactions between different antiepileptic drugs and between antiepileptics and other drugs can be of major significance. Other special features of pharmacotherapy for epilepsy in the elderly include the presence of liver and kidney diseases.
