WebAug 30, 2024 · Alpha waves are a common brainwave frequency. They occur whenever we are awake, but relaxed, with an internal attention. Moreover, an alpha wave is the opposite of beta waves. Unlike beta brainwaves, which tend to be associated with a state of arousal or activity in the brain, alpha tends to be associated with more of a quiet, internal state. WebMar 12, 2024 · A decrease in alpha band power is defined as a hallmark of electroencephalogram (EEG) in Alzheimer’s disease (AD).
