| Panic attack A panic attack is a period of intense fear or psychological distress, typically of abrupt onset and lasting no more than thirty minutes. Symptoms may include trembling, shortness of breath, heart palpitations, sweating, nausea, dizziness, hyperventilation, paresthesias (tingling sensations), and sensations of choking or smothering. Repeated and apparently unprovoked panic attacks may be a sign of panic disorder, but panic attacks are associated with other anxiety disorders as well. For example, people who suffer from phobias may experience panic attacks upon exposure to certain triggers.
