Helping..

Welcome to NeuroTalk.

Your brother should be limiting his Tylenol use. It is not good for a concussed brain. It is also rough on the liver. It would be better if he only took it when a head ache can not be resolved with rest. Head ache is not the only sign of fatigue. Needing to 'stop to think' or strain to focus or reread a line of text are also signs of fatigue.

Hopefully, he has been told to get plenty of quiet rest, meaning low intensity activities with minimal visual and auditory stimulation.

I hope you can help him decide to get the quiet rest his brain needs.

My best to you both.
