Event-related potentials in panic disorder and generalized anxiety disorder.

To evaluate the neurophysiological differences between panic disorder (PD) and generalized anxiety disorder (GAD), 52 patients with PD and 34 with GAD were investigated using event-related potentials (ERP). The ERP were recorded using a tone discrimination task, and peak latencies for N1, P2, N2, and P3 at a Pz electrode site were measured. In addition to analyzing the peak latencies of the ERP, the interpeak latencies (IPL; N1-P2, P2-N2, and N2-P3) were also analyzed.
