Comorbidity of generalised anxiety disorder with other conditions

Abstract

Comorbidity is common with GAD and the majority of patients presenting with GAD also have at least one other diagnosis. Analysis of data from Germany found that comorbidity for any depressive or anxiety disorder was 91.3% (Figure 4.1).¹⁵ This high level of comorbidity is similar to the estimate from the prospective naturalistic follow-up study of patients with anxiety disorders from the Harvard Brown Anxiety Disorders Research Program (HARP) where 83% of patients with GAD had another anxiety disorder.¹⁹
