Usefulness of prolonged video-EEG monitoring in the elderly.
The diagnosis of epilepsy in the elderly can be difficult. We sought to determine whether video-EEG monitoring (VEEG) is useful in the diagnosis and management of elderly patients with epilepsy. We reviewed the medical records of 20 consecutive patients, over 60 years of age, selected from a total of 1423 patients referred over a five year period for VEEG evaluation for epilepsy. The usefulness of VEEG was assessed by comparing changes in (a) the diagnosis and treatment of these patients before and after VEEG, and (b) the assessments made by an epileptologist who reviewed medical records before and after receiving results of VEEG. Compared to the initial diagnosis by the referring physician, VEEG resulted in changes in either the diagnosis or treatment in 11/20 patients based on the results of VEEG. The epileptologist was able to correctly assess the diagnosis and treatment of 16/20 patients without knowledge of the VEEG results. In 4/20 cases, the VEEG provided additional information to the epileptologist. In selected elderly patients, VEEG is useful in establishing the diagnosis of epilepsy, and may change the management of these patients.
