Causes
The exact cause of panic disorder is not entirely understood. However,
researchers believe that panic disorder may be due to chemical imbalances in
the brain. Panic disorder also tends to run in families, so there is likely
a strong genetic connection. Excessive stress and trauma may also be linked
to the development of panic disorder.
Panic disorder may also be caused by certain medical conditions such as
an overactive thyroid (i.e., hyperthyroidism) and certain heart problems.
Things that may trigger a panic attack include:
- drinking large amounts of alcohol
- drinking excessive amounts of caffeine (e.g., coffee, tea, colas)
- taking stimulants or cocaine
- taking or suddenly stopping taking certain prescription medications
