A 30-year-old woman comes to the physician because she has become afraid to leave the house. The patient used to take the train to work every day, but she has experienced increasing anxiety about traveling in an enclosed space surrounded by people. Seven months ago, the patient had a panic attack in a public train station, and she reports feeling “terrified that might happen again.” Ever since that episode, the patient has avoided using public transportation, and she requested to work her job fully remote so that she no longer needs to leave her home. She has also started to avoid other public places where large crowds may be present, which has resulted in her no longer attending her place of worship. She states that she feels safe if she “just stays in the house.” She was diagnosed with major depressive disorder five years ago and was treated successfully with sertraline. She no longer takes any medications. Which of the following is the most likely diagnosis in this patient?

Agoraphobia is an anxiety disorder characterized by a fear of public places. People with agoraphobia often avoid leaving their homes or traveling alone and may feel panicked when confronted with unfamiliar environments. Agoraphobia can be caused by several factors, including previous traumatic experiences, genetic predisposition, and serotonin imbalance.
