It has been clear for some time that a small percentage of people react badly to alpha-theta training. They may feel overly sedated, depressed or have increased pain after training. This appears to be a physiological effect in which they end up in a less functional brain state. It is different from the possible psychological effect of revisiting and working through past traumas. My response until now has been to train beta/SMR first to stabilize the control of physiological state and to keep training beta/SMR after alpha-theta sessions as needed for people with this sensitivity.
I have tried to figure out who these folks are and how to identify them before we get them into trouble. It is not so simple as looking at arousal level as indicated by the appropriate beta/SMR reward frequency. There is no obvious vulnerability in very high or low arousal individuals. There does seem to be some increased likelihood of a negative response in people with instability of brain states, which results in symptoms such as migraine, fibromyalgia, panic attacks and seizures. But this is not always a problem in such individuals. These negative effects have intrigued me for some while because I feel unpleasantly sedated when I train with a standard alpha-theta protocol. I am clearly missing the wonderful calming and clearing effects that people generally report with alpha training. Continue reading “Where is Alpha?”
