Hi fovaju

Welcome to NeuroTalk .

I am sorry to read about your brother.

As far as I can see Tegretol can be used to treat people with epilepsy or trigeminal neuralgia.

If either of these apply to your brother it might be an idea to post in either of these forums https://www.neurotalk.org/forum11/ or https://www.neurotalk.org/forum26/ ; you could get helpful responses from other members.

Best wishes.
