- 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

- 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.

- Anxiety 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
- 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 pseudomeditation control condition. read full text
