Indeed, in It is not clear from these results that anxiety disorders those few instances where anxiety-depression comorbidity are causal.

In other cases, it is equally plausible that ders have early ages of onset, initial treatment must occur the physical condition helped promote the subsequent onset during childhood or adolescence to be maximally effective of anxiety. It is also possible that bidirectional causal influ­ in preventing adverse effects. The eventual resolution of this uncertainty is investigated speed of initial treatment contact after first important for an evaluation of the costs of anxiety disorders, onset of anxiety disorders (67,68). These studies considered as both the direct treatment costs and the indirect costs of three anxiety disorders: GAD, panic disorder, and phobias. Median delays between important because of evidence that anxiety disorders reduce first onset and initial treatment contact were found to be the quality of life of patients with physical disorders (62) more than a decade for some anxiety disorders. Further- and complicate the expression and course of physical disease more, delays were found to be inversely related to age at (63). The most plausible explanation for these findings is onset. This possibility active anxiety disorders receives treatment in a given year. Only about one out of every four people with an anxiety disorder sought any type MENTAL HEALTH TREATMENT of treatment and only 13.

However, a substantial part of the adverse effects of anxiety disorders are associated with Although anxiety disorders typically are not treated, it is a secondary effects that occur early in life (e.

Indeed, people with un­ high prevalence, early age at onset, high chronicity, and treated anxiety disorders make up a large proportion of the substantial role impairment.
