ABSTRACT

The incidence of new-onset epilepsy is high among the elderly. This study presents the demographic characteristics, etiological factors, seizure types and response rates to treatment in a group of patients aged 65 years or over with delayed-onset epilepsy.

The study comprised a retrospective evaluation of the records of 43 patients aged 65 or older with a diagnosis of delayed-onset epilepsy who were admitted to the epilepsy clinic in the Neurology Department of Bezmialem University Faculty of Medicine.

Patient mean age was 74.9 (66–92 years). Underlying disease was found to be cerebrovascular disease in 37.2%. Based on seizure type, 67.4% (n=29) patients had partial-onset and 32.6% (n=14) had generalized seizure. Treatment protocol in 93% (n=40) of the patients was monotherapy antiepileptic drugs, the most commonly used being levetiracetam (53.5%). Assessment of drug side effects showed no complaint in 86% (n=37) of the patients. During the three months prior to the study, 95.3% of the patients had been seizure free.

The study found cerebrovascular disease to be the most common etiological factor in delayed-onset epilepsy. Partial-onset secondary generalized seizure was the most common seizure type. All patients responded well to monotherapy and have a good prognosis.
