[EEG analysis of functional cerebral state during the inter-attack period in patients with vegetative crises (panic disorders)].

Compressive spectral EEG analysis of 30 patients with panic attacks and 24 healthy subjects was conducted. The patients had significantly lower mean total spectral density of a-band power and higher mean spectral density of beta and tau-band power in the right hemisphere vs. the controls. The results are interpreted as an increase in the activating effects of reticulothalamic (arousal 1 system) and temporolimbic (arousal 2) structures during the inter-attack period of panic disorders.
