Neurofeedback with Anxiety and Affective Disorders by Hammond DC Ph.D. ABEN/ECNS< Compelling evidence exists for a neurophysiologic basis for obsessive-compulsive disorder (OCD). A large number of positron emission tomographic and single photon emission computed tomographic studies have found increased blood flow and metabolism in the mediofrontal, anterior cingulate, right frontal, or orbitofrontal areas [1–14], which implicates a cortico-striato-thalamocortical network. Functional abnormalities also have been documented in a large number of quantitative EEG (qEEG) studies [15–22] and evoked potential studies [23–27]. OCD seems to be somewhat heterogeneous, however, with at least two qEEG subtypes that have been found [17–21]. read full text

A Review of EEG Biofeedback Treatment of Anxiety Disorders by Moore NC

Alpha, theta and alpha-theta enhancements are effective treatments of the anxiety disorders (Table 1). Alpha suppression is also effective, but less so (Table 2). Perceived success in carrying out the task plays an important role in clinical improvement. read full text

Case Study: Anxiety and Panic Attacks by The Biocybernaut Institute

This 29 year old woman was a victim of repeated panic attacks. She decided to try alpha brain wave training after the discouraging and ineffective experiences she had while seeking treatment for her condition through the modes of traditional medicine, which included medical doctors, therapists, even hypnotists. read full text

Treatment of Chronic Anxiety Disorder with Neurotherapy: A Case Study by Thomas JE Ph.D. and Sattlberger E B.A.

The objective of the present case study is to report the effects of alpha-decrease biofeedback training on a patient diagnosed with Anxiety Disorder Three Minnesota Multiphasic Personality Inventories (MMPI and MMPI-2) were used as objective measures of treatment efficacy. Following 15 sessions of slow wave inhibit/fast wave increase EEG feedback training, the patient reported a significant reduction in anxiety-related symptoms. read full text (pdf)  

Change Through Electroencephalographic Alpha Feedback Seen Only in High Anxiety Subjects by Hardt JV and Kamiya J

Subjects who were either high or low in trait anxiety used alpha feedback to increase and to decrease their electroencephalographic alpha activity. The alpha changes were tightly linked to anxiety changes, but only in high anxiety subjects (for whom anxiety was reduced in proportion to alpha increases, and was increased in proportion to alpha suppression). read full text  

Evaluating the Efficacy of a Biofeedback Intervention to Reduce Children’s Anxiety by Wenck LS, Leu PW, D’Amato RC

This study explored the reduction of anxiety with children using a combination of electromyograph and thermal biofeedback techniques. One hundred and fifty children (7th and 8th graders) were identified by teachers as anxious and randomly assigned to biofeedback intervention and no-intervention groups. read full text  

Anxiety Change Through Electroencephalographic Alpha Feedback Seen Only in High Anxiety Subjects by Hardt JV and Kamiya J

Biofeedback Treatments of Generalized Anxiety Disorder: Preliminary Results by Rice KM, Blanchard EB, Purcell M Forty-five individuals with generalized anxiety (38 with GAD as defined by DSM-III) were randomized to 4 treatment conditions or a waiting list control. Patients received 8 sessions of either frontal EMG biofeedback, biofeedback to increase EEG alpha, biofeedback to decrease EEG alpha, or a pseudo-meditation control condition. read full text
