Panic disorder
Patient will present as → a 26-year-old first-year PA student with a medical history significant for GERD comes to your office because of frequent episodes of palpitations. The palpitations are sudden in onset and are accompanied by sweating and a sense that she is going to “pass out.” The episodes typically last no more than 10 minutes, and although the patient feels as if she may pass out, she never has. The episodes first appeared when she started PA school and have increased in frequency to the point where she is afraid to attend lectures out of fear of having an “attack.”

  • At least one of the attacks has been followed by one month (or more) of one or both of the following:
