Brain Injury
A brain injury is a neurological condition in which the brain has sustained some form of an injury. There are two types of brain injury: traumatic brain injury and acquired brain injury.
A traumatic brain injury (TBI) is caused by an external physical force to the head such as a fall or a motor vehicle accident. An estimated 1.5 million Americans sustain a traumatic brain injury each year. An acquired brain injury (ABI) is caused by a neurological event that originates within the head such as a stroke, an aneurysm, or an infection. Approximately 600,000 Americans have a stroke every year.
Initially, a brain injury may cause an alteration or loss of consciousness that may last for a short time or even remain for a prolonged period of time. A person in a coma has been unconscious for a prolonged time and cannot be awakened by normal means. A person recovering from a coma may not be aware of his or her surroundings although his/her eyes might be open. Muscle jerking may also occur involuntarily, even in response to pain. The rehabilitation goal for a person emerging from a coma is to improve the person’s arousal and responsiveness by gently stimulating his or her senses.
The effect of a brain injury and the amount of time an individual will experience symptoms as a result of his or her brain injury will vary depending on several factors such as the location and the severity of his or her injury.
