What’s the Difference Between Panic Disorder and GAD?


Updated June 25, 2014

Panic disorder and GAD are both anxiety-related illnesses identified in the DSM-IV-TR. Although they share some common symptoms, including excessive worry, they are distinct illnesses.

Panic Disorder

Recurring panic attacks are the hallmark features of panic disorder. Panic attacks are sudden and intense feelings of terror, fear or apprehension, without the presence of actual danger. The symptoms of a panic attack usually happen suddenly, peak within 10 minutes and then subside. However, some attacks may last longer or may occur in succession, making it difficult to determine when one attack ends and another begins.


The main feature of GAD is excessive and pervasive worry about many everyday life events. This worry is difficult to control, persists for more than 6 months and interferes with daily functioning.

The Focus of Worry

Panic disorder often causes excessive worry about having another panic attack. It is not unusual for one to become so consumed with worry and fear that he or she develops behavioral changes in the hopes of avoiding another attack. This may lead to the development of agoraphobia, which complicates recovery and limits one’s ability to function in usual daily activities.

The focus of worry in GAD generally surrounds many usual life circumstances. For example, excessive worry about finances, job issues, children, and other everyday life events is associated with GAD. This is in contrast to the worry of having a panic attack that is associated with panic disorder.

It should be noted that it is possible to have both panic disorder and GAD. In fact, it is not uncommon for GAD to co-occur with mood disorders or other anxiety disorders. But, in order for a distinct diagnosis of GAD to be made, excessive and pervasive worry about many everyday life events that persists for more than 6 months must be present.

The Importance of Getting Help

The symptoms of panic disorder and GAD can be potentially disabling. But, the vast majority of sufferers will find significant relief with treatment. The sooner treatment begins after the onset of symptoms, the more quickly symptom reduction or elimination will be realized. If you have symptoms of panic disorder, GAD or both, talk to your doctor or other healthcare provider.
