What are Brain Injuries?
A brain injury that is not genetic, congenital, degenerative, or caused by birth trauma is known as an acquired brain injury (ABI). This is a sort of brain injury that occurs after a person is born. The brain’s neuronal activity changes as a result of the injury, affecting the physical integrity, metabolic activity, and functional ability of nerve cells in the brain.
Traumatic and non-traumatic are the two forms of acquired brain injury.
An external force that causes a traumatic brain injury (TBI) is defined as a change in brain function or other signs of brain pathology. There are two types of traumatic impact injuries: closed (or non-penetrating) and open (or penetrating).
A non-traumatic brain injury, also known as an acquired brain injury, occurs when the brain is damaged by internal factors such as a lack of oxygen, exposure to toxins, pressure from a tumor, and so on.
