Abstract
All inpatients aged greater than 55 years with dementia in the Dundee Psychiatric Service were surveyed for seizure occurrence by interviewing staff and reviewing records. Of 208 patients, 19 (9.1%) were recorded as having seizures. The seizures were major in 92% and occurred at a rate of approximately 2.3 seizures per patient per year. Patients with epilepsy were significantly younger than a control group of dementia inpatients and were significantly more cognitively impaired on the survey Clifton Assessment Procedure for the Elderly (CAPE), but not on the Mini Mental State Examination. Of 111 reported accidents, only 5 appeared to be associated with epilepsy. Although epileptic seizures are relatively common in patients with severe dementia, they rarely caused severe problems.
