Panic disorder
A person has panic attacks, which are intense, overwhelming and often uncontrollable feelings of anxiety combined with a range of physical symptoms. Someone having a panic attack may experience shortness of breath, chest pain, dizziness and excessive perspiration. Sometimes, people experiencing a panic attack think they are having a heart attack or are about to die. If a person has recurrent panic attacks or persistently fears having one for more than a month, they're said to have panic disorder.
