The Definition of Concussion

A concussion is a traumatic brain injury that can occur when you hit your head on a moving object or a hard object. It also affects how your brain works.

How Concussions Occur

Some concussions occur by athletic people that play sports like football,soccer and rugby where there is physical contact with your head. Football players get concussions from tackling each other. People that don’t play sports get concussions by hitting their head on a hard surface like another persons head, a brick building or slipping on ice.

  • 1.6 million to 3.8 million concussions occur each year.

  • Impact speed of a professional boxers punch is 20 mph

  • Impact speed of a football player tackling a standing player is 25 mph

  • Impact speed of a soccer ball being headed by a player: 70mph

How Does a Normal Brain Work

  • A normal brain should have no symptoms

  • The brain has tissues and when you have a concussion the tissues can tare

  • A normal brain has 15-100 billion neurons

  • A person with a concussion has 70% of brain cells are dead

  • The brain controls the temperature of blood and pressure

What Happens to your brain During a Concussion

When your head is hit the brain has a fluid that acts like a shock absorbent material but if it is a minor hit to the head it will happen to be a concussion. When your head is hit the brain goes faster into the skull and bruises the brain then it swells up and is damaged. The brain gets damaged by moving around the skull and tears the tissue of the brain.
