There is an increasing literature about the implementation of the staging model in many mental disorders. According to this approach, there are four stages of a psychiatric disorder: prodromal stage, acute manifestations, residual phase, chronic. In this study, we empirically investigate whether additional clinical variables such as clinical manifestations and comorbid disorders may be useful to modify the staging model to panic disorder (PD).

We distinguished inpatient sample (n = 79) with a diagnosis of “panic disorder” according to the DSM-IV criteria. We propose that the inclusion of prodromal stage of PD does not make clinical sense since the different unspecific neurotic symptoms may proceed to a variety of anxiety and depressive disorders. First stage was characterized by the situationally predisposed panic attacks (PA) with both somatic and cognitive symptoms. Comorbid disorders included somatoform disorders and generalized anxiety disorder (GAD). During second stage individuals experienced agoraphobic avoidance until traveling in public transport. On the other hand, spontaneous PA were accompanied by the only somatic but not cognitive symptoms. The most common patterns of comorbidity were GAD and alcohol misuse. Third stage was associated with the absence or limited symptom attacks and chronic agoraphobia. Major depression and obsessive-compulsive disorder might be an integral part of the clinical manifestations. This study supports that the staging model in PD might be updated by the detailed description of clinical manifestations and comorbid disorders at each stage that may help the practitioners to choose the best strategy for the treatment of a particular patient.
