What other anxiety disorders can occur with generalized anxiety disorder?

Social phobia, panic disorder, obsessive-compulsive disorder, and post-traumatic stress disorder are anxiety disorders that can occur in conjunction with generalized anxiety disorder (GAD).

People with social phobia have a persistent, intense and chronic fear that someone is watching and judging them and they will be embarrassed or humiliated by something they say or do. Panic disorder is characterized by repeated panic attacks, or episodes of intense fear that strike often and without warning. Panic attacks cause weakness, dizziness and a pounding heart, leaving one feeling like they are having a heart attack or dying.

Obsessive-compulsive disorder (OCD) leaves one obsessed and unable to control anxious thoughts (e.g. filled with doubt) or rituals (e.g. hand-washing). Post-traumatic stress disorder (PTSD) occurs after exposure to a terrifying event in which grave physical harm occurred or was threatened.

Left untreated, these comorbid anxiety disorders can significantly disrupt daily life and family routines.
