[Treatment of generalized anxiety].

It has been recently hypothesized that anxiety is heterogeneous. Generalized anxiety and panic disorders could be separate entities with specific treatments, as suggested by the fact that some clinical forms of anxiety can be distinguished by characteristic therapeutic responses. The generalized anxiety treatments include benzodiazepines, verbal psychotherapy and relaxation training; they are non mutually exclusive. Nevertheless, at the present time no rational criteria allow to select the best treatment for a particular patient.
