Which syndrome is characterized by sudden onset of severe anxiety, panic attacks, and often physical symptoms?

The syndrome characterized by sudden onset of severe anxiety, panic attacks, and often physical symptoms is known as Panic Disorder. Panic Disorder is defined by the occurrence of recurrent unexpected panic attacks, which are sudden periods of intense fear or discomfort that peak within minutes. These attacks often include symptoms such as heart palpitations, shortness of breath, dizziness, or feelings of choking, which can lead to significant distress and avoidance behaviors. This sudden nature of the episodes and the physical manifestations are what distinctly classify it as Panic Disorder.

In contrast, Generalized Anxiety Disorder involves chronic and excessive worry about various topics, but it does not typically include the same pattern of acute panic attacks. Obsessive-Compulsive Disorder primarily involves intrusive thoughts and compulsive behaviors rather than sudden panic episodes. Social Anxiety Disorder is characterized by fear of social situations and the scrutiny of others, but it does not generally present with the sudden physical symptoms associated with panic attacks. Understanding these differences helps clarify why Panic Disorder aligns with the described symptoms.
