Hypnotherapy and Brain Activity in Generalized Anxiety Disorder
This study uses EEG (a brain wave test) to see how Ericksonian hypnotherapy, a gentle type of hypnosis, affects brain activity and anxiety symptoms in people with Generalized Anxiety Disorder (GAD) who are not currently in treatment or taking medication for anxiety.
