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

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.
