Evaluation of clinical features of elderly epilepsy in China.
Recent data indicate that the prevalence and incidence of epilepsy are high among the elderly, many of whom will have concomitant neurodegenerative, cerebrovascular, or neoplastic disease. The aim of this study is to evaluate the clinical characteristics of elderly patients with epilepsy in China. We retrospectively reviewed the clinical records of 104 outpatients over 50 years of age (average: 63.8 years). The results showed that in the total 104 outpatients, 53 men and 51 women were studied. Twenty-seven (26.0%) patients had idiopathic epilepsy syndromes, and 15 (14.4%) patients were considered cryptogenic. Sixty-two (59.6%) patients had remote symptomatic epilepsy. According to the known etiological factors, cerebrovascular disease (53.2%) is the most common underlying cause, followed by craniocerebral trauma (16.1%), primary or metastatic neoplastic disease (16.1%), and others (14.5%). The most common type of seizure in the group studied was partial seizures (51.9%), followed by generalized seizures (37.5%). Forty-three patients (41.3%) were used combination medication and 61 patients (58.7%) were used single medication. In conclusions, this study provides important data for clinical and research purposes in China. Further research is indicated to confirm the clinical findings of the elderly people with epilepsy by a larger epidemiological study.
