Overcoming Anxiety (Home) > Generalized Anxiety Disorder > Is Gad an Independent Nosologic Entity? Is Gad an Independent Nosologic Entity?In the light of the above, the validity of GAD as a separate entity has been widely discussed. The symptomatic profile of GAD fails to make a sharp distinction with other anxiety disorders, especially panic disorders (PD). GAD has been considered as a mild expression of PD. Alternatively, GAD has been said to represent a residual phase of chronic depression, or even a variant of an anxious personality disorder. Uhde and co-workers found that, in people who develop PD, generalised anxiety symptoms may appear before the first panic attacks or continue after resolution of these panic attacks. Adding to the unsatisfactory delineation of GAD at a cross-sectional level, such findings warrant a closer look at a number of studies on the validity of GADas an independent disorder. We will briefly report on a number of family, clinical and challenge studies that tried to compareGADwith PD, after a careful exclusion of any lifetime history of PD in the analysed GAD population.
