Gamma as high frequency brain activities are involved in attention, senses (smell, sight, and hearing), mental processing, and perception, which change in Alzheimer’s disease (AD). To unmask abnormal gamma power in healthy individuals at high-risk of developing AD, HMRI’s neurosciences researcher Xianghong Arakaki MD, PhD (NIA R56AG063857) led the electrophysiology core of a brain aging study that combined memory challenge with quantitative electroencephalography (qEEG). The pilot findings encourage further investigations in developing neurophysiology-based markers for identifying individuals at risk, to help improve our understanding of AD pathophysiology and were published in Frontiers In Aging Neurosciences. The brain aging study was led by Michael Harrington, MB, ChB, FRCP (L. K. Whittier Foundation).
