Brain Damage: Symptoms, Causes, Treatments
What Causes Brain Damage?
When the brain is starved of oxygen for a prolonged period of time, brain damage may occur. Brain damage can occur as a result of a wide range of injuries, illnesses, or conditions. Because of high-risk behaviors, males between ages 15 and 24 are most vulnerable. Young children and the elderly also have a higher risk.
Causes of traumatic brain injury include:
- Car accidents
- Blows to the head
- Falls or accidents
- Physical violence
Causes of acquired brain injury include:
- Poisoning or exposure to toxic substances
- Strangulation, choking, or drowning
- Neurological illnesses
- Abuse of illegal drugs

How Are Brain Damage and Brain Injuries Treated?
Anyone who has a head or brain injury needs immediate medical attention.
A brain injury that seems mild -- referred to as a concussion -- can be as dangerous as clearly severe injuries. The key factor is the extent and location of the damage. Brain injury does not necessarily result in long-term disability or impairment. But the correct diagnosis and treatment is needed to contain or minimize the damage.
The extent and effect of brain damage is determined by a neurological exam, neuroimaging testing such as MRI or CT scans, and neuropsychological assessments. Doctors will stabilize the patient to prevent further injury, ensure blood and oxygen are flowing properly to the brain, and ensure that blood pressure is controlled.
Almost all patients will benefit from rehabilitation to assist in long-term recovery. That may include:
- Occupational therapy
- Speech and language therapy
- Psychological support
