Although how long a panic attack lasts can vary greatly, its duration is typically more than 10 minutes. A panic is one of the most distressing conditions that a person can endure, and its symptoms can closely mimic those of a heart attack. Typically, most people who have one panic attack will have others, and when someone has repeated attacks with no other apparent physical or emotional cause and it negatively changes their behavior due to the attacks or feels severe anxiety about having another attack, he or she is said to have panic disorder. A number of other emotional problems can have panic attacks as a symptom. Some of these illnesses include posttraumatic stress disorder (PTSD), obsessive-compulsive disorder, schizophrenia, and intoxication or withdrawal from alcohol and certain other drugs of abuse.
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
