36 year old male with numbness of right side head, neck, arm and leg. Cat scan is clear. Is he going to die? What is it? He has hypertension.

Loaded question. The potential diagnoses for the above depends on time(how long have the symptoms lasted), circumstances (when/how did they develop, did they appear concurrently or at different times, are they progressing or resolving), and severity. The possiblts run from migraine, small lacunar stroke that may later show up on mri, pinched nerve, autoimmune or infectious causes, etc...Outcome depends on cause.
