An overview on Brain Injuries – and how it impacts you

In Canada, brain injuries are 30 times more common than breast cancer, 44 times more common than spinal cord injuries, and 400 times more common than HIV/AIDS.

Approximately 452 people suffer from a brain injury daily in Canada, which results in one person with a traumatic brain injury every 3 minutes. Brain damage is an injury that causes the deterioration or destruction of brain cells and can be categorized into two types.

Traumatic Brain Injury

This is type of injury is caused by an external force such as a blow to the head, which causes the brain to shift inside the skull or the external force damages the skull. 

Acquired Brain Injury 

This type of injury occurs at the cellular level and is associated with pressure on the brain, in such cases as a tumour or neurological illness.

Mild brain injuries may be temporary and cause headaches, confusion, nausea and memory problems. Symptoms can be more pronounced and can last longer with a moderate brain injury. With both types, most patients make a good recovery, although approximately 15% of people will have continual problems after one year.

Because of high-risk behaviours, men aged between 15 to 24 are most vulnerable to brain damage. Young children and the elderly are also at a higher risk. Causes of traumatic brain injury include car accidents, falls or accidents, sports injuries and physical violence. Tumours, heart attacks, abuse of illegal drugs and exposure to toxic substances cause acquired brain injuries.

The symptoms of brain damage fall into four categories — cognitive, behavioural/emotional, perceptual and physical.
