Did you know that car accidents are the primary cause of brain injuries? And so is falling from a height, domestic violence and a rise in crime-related attacks. The brain is responsible for almost all the activities going on in our bodies. So you can imagine how life-changing and difficult it is to cope with an injury that may never fully heal.

Furthermore, studies have compared brain injury at a young age versus in the mid 30s-40s. And it shows that school/college students who pursue higher education are more likely to recover and grow, unlike those who suffer TBI at an old age. People with TBI in their old age are at risk of developing neurodegenerative diseases like Parkinson’s, dementia, or Alzheimer’s disease.

However, due to insufficient research and proven experiments, most neurologists say that it’s nearly impossible to carry out a controlled experiment since all patients have different symptoms depending on the severity of their injury. Medically the severity of a brain injury is categorized into three main types:

1. Mild TBI
2. Moderate TBI
3. Severe TBI

Which is determined by the time a person stays in a coma as well as the damaged tissue in the brain. 

Mild TBI

A mild TBI, a.k.a. a concussion is a temporary head injury that can take up to a few weeks or months to heal. You might have experienced a jolt or knock to your head while falling, which causes your brain to move rapidly inside your skull. This results in dizziness and losing consciousness/blacking out for a few minutes. Another concussion in the near future can prove to be fatal.

Moderate TBI

A moderate TBI puts the person in a sensitive spot, which can either end up developing into severe TBI or get better with a lot of care. It can also be diagnosed as diffuse axonal injury in which the brain’ white matter is damaged. The white matter consists of multiple axons (nerves that transmit electrical impulses). Due to a hard blow or sports-related accidents, axons get stretched and tear apart. This can have an adverse effect on the entire body since the connection between body nerve cells is temporarily lost with the brain.

Severe TBI

Extreme car accidents, assaults, gunshot wounds, and sports injuries are some causes of severe TBI. The brain experiences sharp acceleration and deceleration within the skull that may lead to different types of hematoma, contusions, brain hemorrhage, and chronic fatigue and PTSD. Severe TBI needs extreme care and support; otherwise, it can develop into CTE that can result in the person taking their own life. Due to the harsh impact on the brain, tiny blood vessels get ruptured, which results in a lot of blood loss. It can also lead to blood clots or brain tumors to grow.
