A person who experiences feelings of terror and fear at times when no actual danger is present may need to be evaluated for a panic disorder. Such panic attacks can last for about 10 minutes at a time and may be accompanied by a variety of symptoms such as sweating, shortness of breath, a racing heartbeat, nausea and dizziness, and they can occur out of the blue, with no advance indications. Although both men and women can have panic disorder, more women than men are diagnosed with it. Those with a family history of anxiety or panic disorders, those who abuse alcohol or drugs and people with certain brain abnormalities are all more likely to develop panic disorder. Thankfully, patients with panic disorder can be effectively treated via medications along with psychotherapy, cognitive behavioral therapy and instruction in relaxation techniques.
