Neurofeedback.

In many cases, anxiety is associated with decreased alpha waves and increased beta waves. Neurofeedback teaches you to modify your brainwaves to achieve the desired brainwave state.

With consistent neurofeedback training, we can rewire our brain pathways. When it comes to using neurofeedback for anxiety, alpha-theta neurofeedback training, which reduces arousal, has been applied to reduce anxiety and create a generally relaxed state of well-being.
In a study of highly talented musicians performing under stressful conditions, only musicians who received alpha-theta neurofeedback training had enhanced musical performance under stress.
In another study, adolescents with self-reported attention and anxiety symptoms had enhanced alpha and SMR along with improved symptoms (by visual analog scales) after neurofeedback training of alpha, theta, and SMR twice a week for five weeks (SMR training commonly improves focus and attention by decreasing drowsy, mind-wandering theta waves and anxious or racing high beta waves while increasing the calm, focused SMR waves).
In one RCT of test anxiety, neurofeedback participants generated 33% more alpha and showed a significant anxiety reduction; by comparison, untreated participants and those receiving relaxation training experienced no significant symptom reduction.
