Nocturnal panic and trauma.

ABSTRACT

We examined the recollection of traumas in panic disorder patients with and without history of nocturnal panic attacks. From a sample of 154 patients seeking treatment for panic disorder, almost 85% of those with nocturnal panic reported a history of traumatic events in comparison to only 28% without nocturnal panic. Fear of loss of vigilance is considered as a potential mediator of the relationship between nocturnal panic and traumatic events.
