Among patients I see with Panic Disorder, a striking number have symptoms in specific situations. Persons with Panic Disorder have spontaneous attacks of intense fear and discomfort that begin abruptly, almost like an adrenaline rush or flight or fight reaction, like palpitations, sweating, shaking, intense fear, tremor, inability to catch one’s breath. These sensations occur on spontaneously or when in specific situations such as a car or supermarket. Sensitivity to a car or market is so typical, it bolsters the diagnosis of a panic attack. Whenever I suspect panic disorder, I always ask specifically about reactions to being in a car or supermarket. Most of the time the person will mention it on their own. It is enough to make you wonder what’s so unusual about these particular situations?
