[A clinical trap: acute and chronic psychogenic dyspnea].

Psychogenic dyspnea may be part of two main clinical pictures. The first one is acute with dyspnea in the foreground of a panic disorder with or without agoraphobia. The second one is chronic, dyspnea being a background symptom of a generalized anxiety disorder. The problems related to the diagnosis and the implementation of psychological or pharmacological treatments are reviewed with reference to evidence-based medicine.
