Elderly passenger flies 13 hours direct to Asia in business class. 24 hours after arriving has a headache, takes an aspirin and lies down. Wakes up a few hours later with no headache but side vision impaired in left eye. Goes to hospital, CT scan reveals an intracerebral hemorrage affecting the portion of the brain that controls vision (all other bodily functions 100% normal). Patients receives treatment (daily IV of 250 ml of Sodium Chloride 0.9% and 250ml of Glycerol & Fructose) and rest in hospital for 3.5 weeks. Weekly CT scans shows steady improvement and the patient walks 30 - 40 minutes daily in 5 - 10 minute intervals (could do more but wanted to not over exert) over the last several days. Passenger's weight, blood pressure, temperature, cholestrol levels fully normal prior/during/after the incident.

Is this passenger ready to fly home direct in business class with a nurse escort 3.5 weeks after the initial incident? Any general rules regarding recovering after a stroke and air travel?
