Anxiety Disorders are a group of mental disorders characterized by significant feelings of anxiety and fear. Anxiety is a worry about future events, and fear is a reaction to current events.
How can an EEG help with Anxiety Disorders?
In the last 25 years, there has been an explosion of research concerning hemispheric brain asymmetries as they relate to certain dimensions of emotion, personality, and psychopathology. A substantial number of electroencephalographic (EEG) studies have found a link between hemispheric asymmetry in frontal regions of the cortex and depressive/anxiety symptoms.
Research StudyEEG Brain Scans Can be Used to Aid in the Diagnosis of Anxiety:
(Ryan Thibodeau, et al. Depression, Anxiety, and Resting Frontal EEG Asymmetry: A Meta-Analytic Review, Journal of Abnormal Psychology 2006, Vol. 115, No. 4, 715–729)
- This meta-analyses examined 26 different studies, with 1,673 participants ranging from 12-64 years of age.
- F3/F4 Alpha brain wave ratio was used as an indicator of anxiety. Values outside of normal (.8-1.2) were suggestive clinical anxiety.
Prevalence (From the Anxiety and Depression Association of America)
