People with PD experience considerable distress during panic attacks.
As a result, they develop strong fears and anxieties about having more panic
attacks which can lead to significant behaviour change.
For instance, many people become so concerned about
panicking that they avoid everyday situations that could potentially cause
panic (e.g. going to the shops or exercising).
Repeated avoidance of situations often develops into agoraphobia, which refers to an
inability to go outside of known and safe surroundings because of intense fear
with agoraphobia avoid situations where escape might be difficult or help is unavailable
in the event of having a panic attack. The majority of people with agoraphobia
also have PD, but some do not and have never had a panic attack.
