Panic attacks, on the other hand, are short bursts of intense fear often marked by increased heart rate, brief chest pain or shortness of breath. Typically lasting fewer than 30 minutes, they could occur once or repeatedly — sometimes without reason. These episodes can send patients to the emergency room, as they are sometimes mistaken for a heart attack.
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
