Among the forms of pathological anxiety, the DSM-IV-TR [1] distinguishes, in addition to generalized anxiety, phobias, panic attacks, posttraumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD). There are some theories that since OCD involves structural and functional organic deficits, it is questionable whether it can be classified as an anxiety or depressive disorder [2]. The ICD-10 [3] in fact classifies this disorder separately from the other manifestations often associated with it.
