The major goals of the study are to 1) characterize hippocampal activity in patients with
mild cognitive impairment (MCI) due to Alzheimer's disease (AD) and AD who have suspected
hippocampal epileptic activity based on scalp EEG recordings from IRB # 21-001603; 2) study
the efficacy of brivaracetam to suppress epileptic activity and pathological high frequency
oscilations (pHFOs) during hippocampal depth electrode and scalp EEG in patients with MCI and
AD; and 3) investigate the effects of brivaracetam on cognition in an open-label pilot study.
