Energy Crisis During Concussion

Find out what happens within the cells of the brain during a concussion.

During a concussive injury, Potassium ions (K+) exit the neuron, while Calcium ions (Ca) rush into the cell. When the Calcium enters, it causes the blood vessels to constrict, resulting in decreased blood supply to the brain. This diminished cerebral blood flow causes the increased demand for energy, hence the “energy crisis.”

The nerve cell is extremely vulnerable in this condition, and further injury or stress while impaired may cause cell death or serious cell damage.
