There are long-term, biological, environmental, and social causes of panic attacks. In 1993, Fava et al. proposed a staging method of understanding the origins of disorders. The first stage in developing a disorder involves predisposing factors, such as genetics, personality, and a lack of wellbeing. Panic disorder often occurs in early adulthood, although it may appear at any age. It occurs more frequently in women and more often in people with above-average intelligence. Various twin studies where one identical twin has an anxiety disorder have reported a 31–88% incidence of the other twin also having an anxiety disorder diagnosis.
Panic disorder is a diagnosis given to people who experience recurrent unexpected panic attacks— that is, the attack appears to occur from out of the blue. The term recurrent refers to the fact that the individual has had more than one unexpected panic attack. In contrast, expected panic attacks occur when there is an obvious cue or trigger, such as a specific phobia or generalized anxiety disorder. In the U.S., roughly 50% of people with panic disorder experience both unexpected and expected panic attacks.
Panic attacks involve sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. People experiencing a panic attack may believe they are having a heart attack or they are dying or going crazy. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms:
Cognitive Behavioral Therapy (CBT) is an example of one type of psychotherapy that can help people with anxiety disorders. It teaches people different ways of thinking, behaving, and reacting to anxiety-producing and fearful objects and situations. CBT can also help people learn and practice social skills, which is vital for treating social anxiety disorder.
