Title: Alpha desynchronization during simple working memory unmasks pathological aging in cognitively healthy individuals
Published: January 2, 2019
The brain is damaged more than ten years before any symptoms of Alzheimer’s appear. This is detected in spinal fluid chemistry, where brain stress shows up. We want to detect this pre-symptomatic stage, which would be important to test treatments before memories are lost. This study examined whether or not we could detect this early stage, having individuals wear an EEG hat while individuals performed simple computer tests. We found those who are cognitively healthy but have stressed chemistry in their spinal fluid had to use more of their brain EEG rhythms in the test compared to those with normal chemistry.
