A 54-year-old male with generalized anxiety disorder presents to the psychiatric urgent care clinic requesting refills of his medications. He reports that he has been taking alprazolam 2 mg three times daily for the past eight years, prescribed by a previous provider who has retired. He ran out of alprazolam four days ago and has been unable to obtain refills. He appears diaphoretic and tremulous. Vital signs reveal heart rate 112 bpm, blood pressure 162/98 mmHg, and temperature 37.9°C. He reports poor sleep, increased anxiety, and one episode of visual distortion described as 'the walls moving.' His last alcoholic drink was three weeks ago, and his urine drug screen is positive only for benzodiazepines at low levels. Which assessment finding constellation most accurately stratifies this patient's seizure risk?
