Traumatic brain injury (TBI) occurs when a blow or jolt to the head or a penetrating head injury disrupts brain function. TBI can result in short or long-term problems with independent function
Acquired brain injury (ABI) is defined as damage to the brain that occurs after birth and is not related to a congenital disorder or a degenerative disease. May be caused by a traumatic head injury or by non-traumatic cause (i.e. tumor, aneurysm, anoxia, infection, drugs or alcohol.)
Diffuse brain injury is brain damage that can affect many parts of the brain, often subtly; examples are diffuse axonal injury and inadequate blood flow.
Anoxic brain injury is when a brain does not receive adequate oxygen, usually resulting from a serious accident where heavy bleeding occurs
Symptoms Any brain function can be disrupted by brain trauma: excessive sleepiness, inattention, difficulty concentrating, impaired memory, faulty judgment, depression, irritability, emotional outbursts, disturbed sleep, diminished libido, difficulty switching between two tasks, and slowed thinking.

When to seek medical advice
Always get checked by a doctor if you have suffered a blow to the head. Anyone with signs of moderate or severe brain injury (such as convulsions, weakness or numbness in the extremities, repeated vomiting, or slurred speech) should receive immediate medical care. These types of brain injuries can quickly become life-threatening.
