Concussion

Better preconditioning is expected to produce a smaller voltage dip after injury and a faster return to baseline. Loss of consciousness is not required for concussion. Concussion is a broad sports medicine issue beyond football alone. Modern concussion care recognizes possible long-term effects rather than minimizing head injury. Concussion is described as a cascade of changes rather than a single simple event. The article frames mitochondrial dysfunction or death as especially important in concussion physiology. The article says WAVi data showed that brain voltage and signal processing may remain suppressed after conventional clearance. Voltage suppression after concussion is described as reaching as high as 80 percent. A concussion can produce frightening cognitive, sensory, physical, and emotional symptoms.
