In this brief segment, David Brimacombe explains that after a concussion or during post‑concussion syndrome the brain’s energy reserves are severely limited. Because the brain cannot generate sufficient new energy, even routine daily decisions—what to wear, what to eat, whether to socialize or stay home—consume a disproportionate amount of the remaining cognitive “battery.” This constant decision‑making quickly depletes the already‑reduced energy stores, leading to the persistent fatigue that many concussion patients experience.

Every decision you make in the day consumes energy. Now, understand that when you are recovering from a concussion or you have post-concussion syndrome, your energy stores are limited. Your brain's ability to actually create more and the sufficient amount of energy is limited as well. So, always thinking about what am I going to wear today? What should I eat? What should I do after work? Should I go and hang out with my friends? Should I stay home? All those small little choices that you have to make drain your energy, and as your battery is only getting charged halfway, they all drain quickly.
