Review Question - QID 210868

A 59-year-old woman is referred to a neurologist for a hand tremor. Her symptoms began a few months prior to presentation and has progressively worsened. She noticed she was having difficulty drinking her coffee and writing in her notebook. The patient reports that her father also had a tremor but is unsure what type of tremor it was. She drinks 2-3 glasses of wine per week and only takes a multivitamin. Laboratory studies prior to seeing the neurologist demonstrated a normal basic metabolic panel and thyroid studies. On physical exam, there is a mid-amplitude 8 Hz frequency postural tremor of the right hand. The tremor is notable when the right hand is outstretched to the very end of finger-to-nose testing. Neurologic exam is otherwise normal. Which of the following is the best treatment option for this patient?
