The tremor is accompanied by sudden restlessness and nausea, which disrupts her daily work as a professional violinist. The symptoms worsen shortly before upcoming concerts but also appear when she goes for a walk in the city. She is concerned that she might have a neurological illness and have to give up her career. The patient experiences difficulty falling asleep because she cannot stop worrying that a burglar might break into her house. Her appetite is good. She drinks one glass of wine before performances to calm her nerves and otherwise drinks 23 glasses of wine per week. The patient takes daily multivitamins as prescribed. She appears nervous. Her temperature is 36.8C 98.2F, pulse is 92min, and blood pressure is 13580 mm Hg. Mental status examination shows a full range of affect. On examination, a fine tremor on both hands is noted. She exhibits muscle tension. The remainder of the neurological exam shows no abnormalities. Which of the following is the most likely explanation for this patients symptoms?? A: Generalized anxiety disorder, B: Essential tremor, C: Adjustment disorder, D: Panic disorder, E: Atypical depressive disorder,  <response>: This is a clinical case scenario about a 36-year-old female violinist presenting with an 8-month history of tremor, restlessness, and nausea that worsens before performances. The key findings are episodic tremor, anxiety about performances and other situations, difficulty sleeping due to worry, and fine tremor on exam. This presentation is most consistent with generalized anxiety disorder given the pervasive anxiety and worry across multiple situations leading to physical symptoms. Essential tremor would not explain the anxiety symptoms. Adjustment disorder may cause anxiety but is tied to an identifiable stressor and would not explain the longer timeline. Panic disorder may explain the episodic symptoms but not the persistent worry. Atypical depression may have anxiety but lacks the full criteria for GAD.A: Generalized anxiety disorder
