Everyone with PCS or a TBI reacts differently to caffeine. All of my doctors have said NO, absolutely NO!.

I know many who it does not effect, and some if helps.

For me, caffeine is a nightmare. With an injury your brain cells can become extra sensitive to chemicals, medications and the like. The last cup of coffee I had I was up for for days. It sent me into a manic episode I had a very dangerous crash from!

Caffeine in a brain injured individual can contribute to other symptoms, or add symptoms, such as sleep disruption and fatigue. It has also reported to deplete the bodies natural production of adrenaline.

Caffeine also inhibits glucose utilization in the brain. Glucose is one of the brains major tools for healing.

Learn how your reacts to it. But be careful. The medical community jury is on the fence on this one. So use your best judgment!
