What is a brain injury?

A brain injury may be caused by trauma or may be acquired due to a medical illness. A Traumatic Brain Injury is due to some force affecting the brain. This may include a blow to the head, a fall, a motor vehicle accident, or some other type of process. An Acquired Brain Injury may be due to a stroke or other neurological disorder. These type of brain injuries may alter one’s thinking, behavior, emotions, and physical state. These injuries impact not only the patient but also their caregivers.
