A panic attack is a sudden, intense episode of fear or discomfort that reaches its peak within minutes and is often accompanied by physical symptoms such as a racing heart, shortness of breath, chest pain, dizziness, or abdominal distress. These attacks can occur unexpectedly or be triggered by specific situations. During a panic attack, individuals may feel a sense of impending doom or a loss of control. The intensity and rapid onset of these symptoms can be so overwhelming that many people experiencing a panic attack may think they are having a heart attack or another serious medical issue.

An anxiety attack, on the other hand, is a period of excessive worry or fear that is often related to a specific stressor or situation. Unlike panic attacks, which are sudden and intense, anxiety attacks build up gradually and can last for a longer duration, from minutes to hours. Symptoms of anxiety attacks can include restlessness, muscle tension, fatigue, irritability, and difficulty concentrating. While anxiety attacks can be highly distressing and interfere with daily activities, they are generally less intense than panic attacks. The key difference between the two lies in the suddenness and severity of panic attacks compared to the more gradual and prolonged nature of anxiety attacks.
