Panic attacks are sudden periods of intense fear that may include palpitations, sweating, shaking, shortness of breath, numbness, or a feeling that something bad is going to happen. The maximum degree of symptoms occurs within minutes. Typically they last for about 30 minutes but the duration can vary from seconds to hours. There may be a fear of losing control or chest pain. Panic attacks themselves are not dangerous physically. Panic attacks can occur due to number of disorders including panic disorder, social anxiety disorder, post traumatic stress disorder, drug use disorder, depression, and medical problems. They can either be triggered or occur unexpectedly. Smoking and psychological stress increase the risk of having a panic attack. Before diagnosis, conditions that produce similar symptoms should be ruled out, such as hyperthyroidism, hyperparathyroidism, heart disease, lung disease, and drug use. Treatment of panic attacks should be directed at the underlying cause. In those with frequent attacks, counselling or medications may be used. Breathing training and muscle relaxation techniques may also help. Those affected are at a higher risk of suicide. In Europe about 3% of the population has a panic attack in a given year while in the United States they affect about 11%. They are more common in females than males. They often begin during puberty or early adulthood. Children and older people are less commonly affected.
