Epileptic Hippocampus in Alzheimer's Disease
University of California, Los Angeles
Summary
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.
Description
This is a prospective, single-center, open-label, pilot study. Individuals with mild cognitive impairment (MCI) and Alzheimer's disease (AD) who show epileptic activity as part of an overnight EEG from study IRB#21-001603 or as a part of a clinical EEG will be eligible. After informed consent, participants will undergo hippocampal depth electrode placement and full scalp electroencephalogram (EEG) recordings to characterize epileptic hippocampal activity and pathological high frequency oscilations (pHFOs). During recordings, the investigators will determine whether brivaracetam, given intraven…

Interventions
- DrugBrivaracetam
* Intravenous administration: 25 mg or 50 mg will be administered depending on its effects on epileptic activity during a hospital stay where simultaneous EEG and depth electrode recordings will be measuring epileptic activity. * Oral administration: Subjects will take 25mg or 50mg twice a day for 12 months. The dosage will depend on its effects on epileptic activity. Brivaracetam levels will be measured on months 3, 6 and 12.
