Brain Injuries

There are a variety of brain injuries, but some of the most common are:

• Anoxia: This is caused by oxygen deprivation such that the brain doesn’t receive any oxygen. Cell death occurs, which can result in serious functional damage to different brain systems and possible death. 
• Concussion: These are the most common type of traumatic brain injury and are caused by direct impact trauma to the head. Severe concussions can result in permanent damage.
• Contusion: Similar to concussions, they are also caused by direct impact trauma to the head. A contusion is basically bleeding in the brain in one specific area. Contusions may need to be surgically removed, as blood clot formation at the contusion site can be lethal. 
• Diffuse Axonal Injuries: These are caused by severe shaking or rotational forces, which creates tears in the brain when the skull grazes the edges of the brain. 
• Hypoxic Brain Injury: Similar to anoxia, there is oxygen deprivation, except that it is not absolute. With a hypoxic brain injury, the brain receives some oxygen, but the oxygen levels are still dangerously unsatisfactory. Like anoxia, cell death may still occur, though at a slower rate. The eventual cell death, if left untreated, may also result in functional damage and possible death.
• Penetration Injuries: Caused by sharp objects entering the skull and brain, there may be lost tissue, shearing, tearing, and rupturing of accessory tissue. This can be fatal or may cause significant and long-term effects.

There are numerous consequences of traumatic brain injury such as, loss of memory, depression, lack of concentration, headaches, anxiety, anger issues, and personality changes. The decreased ability to focus can also decrease your motivation.
