Panic Disorder is characterized by recurrent, unexpected panic attacks—sudden surges of intense fear or discomfort that peak within minutes—accompanied by persistent concern about future attacks or behavioral changes to avoid them. Symptoms may include palpitations, shortness of breath, dizziness, trembling, or fear of losing control or dying. While panic attacks can occur in other disorders, Panic Disorder is diagnosed when these episodes become recurrent and lead to avoidance or functional impairment. Treatment focuses on helping clients reinterpret bodily sensations, reduce fear of panic itself, and resume previously avoided activities.
