We often hear the term called "Concussion" during some sporting events especially during Cricket matches. When a high speed bowl just hits the helmet or head, the game is halted for few minutes and Physio runs into the field to do a Concussion test.
Inside the Skull of the brain there is a shock absorbing fluid protecting the brain. During Concussion, the brain bounces around in the skull, accelerating, decelerating or rotating. This creates a series of impact in the brain. The neurons in the brain are rattled and between those neurons there are axons - a thin fibre that transmits electrical impulse, stretches or breaks. This impact has severe affect on the blood flow to the brain and damages the energy producing mitochondria in the neurons. You can compare it with an earthquake within the brain. These are also called as Traumatic Brain Injury.
Symptoms of Concussion:
- Headaches

- Having Imbalance
