QUANTITATIVE EEG CORRELATES OF PANIC DISORDER

Quantitative analysis of electroencephalographic (EEG) signals recorde d from multiple scalp sites was used to compare panic disorder patient s (n = 34) with normal healthy controls. Patients exhibited greater ov erall absolute power in the delta, theta, and alpha frequency bands;In d less relative power in the beta band. Discriminant analysis of absol ute power;indices correctly classified 75% of the subjects, while rela tive power indices exhibited a 69% correct-classification rate. Absolu te delta and theta power were positively correlated with observer rati ngs of anxiety, while relative beta power was related to self-ratings of anxiety.
