Generalized anxiety disorder (GAD) is a diagnosis listed in the DSM-IV-TR under anxiety disorders and is defined specifically by the excessive amount of worry the patient experiences (AP A, 2000). Many different treatments and treatment techniques are used to treat GAD symptoms including cognitive-behavioral therapy, psychotherapy, pharmacology, and complementary and alternative medications. The efficacy of these general treatments will be reviewed with an emphasis on neurofeedback. Finally, a study to demonstrate that neurofeedback training can reduce GAD symptoms is proposed. Previous studies have focused on training the alpha or theta brain wave to reduce anxiety. However, these studies have generated many conflicting results. In this study it is proposed that suppressing the beta brain wave, a brain wave found to be associated with anxiety. It is hypothesized that suppressing beta will significantly reduce anxiety symptoms in participants.
