Abstract:
Measuring of the amplitude of auditory cognitive evoked potentials P300 showed its changes (decrease and increase) in patients with panic disorders compared to healthy individuals. The authors hypothesize that the decrease in P300 amplitude reflects increased activity of the cerebral reticulothalamic structures, while its increase is associated with activation of the septohippocampal limbic system in patients with panic disorders. P300 recording can serve as a valuable diagnostic method.
