A limited symptom attack (LSA) or limited symptom panic attack is a milder form of panic attack where a person experiences fewer than four of the standard DSM-5 panic symptoms. [1]

Key Characteristics

Symptom Count: Involves 1, 2, or 3 panic symptoms (such as a racing heart, trembling, dizziness, or a sudden fear of dying) instead of four or more. [1, 2, 3, 4]
Duration: Typically peaks within 10 minutes and can last from 1 to 5 minutes, or persist as part of a waxing and waning episode for several hours. [1]
Context: They frequently occur in people with panic disorder, phobias, or agoraphobia, and are commonly experienced by individuals recovering from or undergoing treatment for panic disorder as symptoms decrease in intensity. [1, 2]
Impact: Even though they involve fewer symptoms, they can still cause significant distress, physical discomfort, and worry. Learn more about symptom criteria through the Anxiety & Depression Association of America. [1, 2]
