While some companies do adopt and indeed support working from home (via remote administration), many companies do not tend to make it perpetual. This is because they want their employees working in the offices where they can be seen working and earning their salary/wages. Very few companies support working from home for any real length of time, and even then it is only after you have worked for the company for a while and have proven you are a hard worker and are infact taking advantage of the opportunity responsibly.
I highly recommend you have your boyfriend consult with a neurologist (who, of course, specializes in epilepsy) and see what choices are available today. New things come out every year, and if it has been a while since he last saw one, he may be pleasantly surprised to see new things available. It definitely would not hurt.
