The patient was at an appointment to receive welfare when he began acting abnormally. The patient was denied welfare. Shortly afterwards, he no longer responded to questions and stared blankly off into space, not responding to verbal stimuli. Other than odd lip-smacking behavior, he was motionless. Several minutes later, he became responsive but seemed confused. The patient has a past medical history of drug abuse and homelessness and is not currently taking any medications. His temperature is 98.9F 37.2C, blood pressure is 12478 mmHg, pulse is 90min, respirations are 14min, and oxygen saturation is 99 on room air. Physical exam reveals cranial nerves II-XII as grossly intact with 55 strength in the upper and lower extremities and a stable gait. The patient seems confused when answering questions and has trouble remembering the episode. Which of the following is the most likely diagnosis?? A: Absence seizure, B: Complex partial seizure, C: Generalized seizure, D: Malingering, E: Transient ischemic attack,  <response>: Based on the information provided in the question stem, the key findings are:- 27-year-old homeless man with history of drug abuse - Became unresponsive and had odd lip-smacking behavior during a welfare appointment when he was denied welfare- After a few minutes became responsive but confused- Vital signs are normal- Physical exam is normal except for confusion- Trouble remembering the episodeThis presentation is most consistent with a complex partial seizure focal onset impaired awareness seizure. The unresponsiveness, lip smacking, and confusion afterwards point to a seizure. The lack of generalized convulsions makes generalized seizure unlikely. The normal neurologic exam makes TIA unlikely. Absence seizures are very brief and lack the lip smacking. Malingering may be a consideration in this population, but the lip smacking makes a true seizure more likely.B: Complex partial seizure
