Prevalence of Epilepsy and Sleep Wake Disorders in Alzheimer Disease

Alzheimer disease is the most common of the neurodegenerative diseases. Epilepsy and sleep wake disorders are co-morbid conditions of Alzheimer disease. The investigators propose a prospective study using long-term EEG monitoring in combination with polysomnography to determine prevalence of epilepsy and sleep wake disorders in Alzheimer disease, and correlate these findings with clinical data, Alzheimer disease biomarkers and imaging studies (MRI and amyloid/tau-PET). In selected patients, the investigators will perform EEG studies with foramen ovale electrodes. The ultimate goal is to improve the outcome of patients with Alzheimer disease by early treatment of epilepsy and restoring sleep-wake disturbances.
