Panic disorder is a mental health condition characterized by recurrent and unexpected episodes of intense fear, known as panic attacks. These attacks can cause physical symptoms such as a racing heart, shortness of breath, and dizziness. Individuals may feel a sense of impending doom or loss of control during these episodes. People with panic disorder often worry about experiencing future attacks, which can lead to changes in behavior and avoidance of certain situations. Treatment options include therapy, such as cognitive-behavioral therapy, and medications that can help manage symptoms and reduce the frequency of attacks.
