In this segment, the speaker explains why individuals experiencing post‑concussion syndrome (PCS) often feel completely drained. He highlights that the brain, despite representing only about 2 % of body weight, consumes roughly 20 % of the body’s total energy. After a concussion, the brain’s metabolic needs increase while its capacity to generate energy diminishes, creating a paradox: the brain demands more fuel but cannot produce enough. This mismatch underlies the pervasive fatigue reported by PCS patients.
