What is a Traumatic Brain Injury?

A traumatic brain injury (TBI) occurs when a sudden, external force damages the brain. This can happen from a blow, bump, or jolt to the head, or when an object penetrates the skull.

TBIs can range from mild, like a concussion, to severe, involving extended periods of unconsciousness or amnesia. Traumatic brain injuries can have significant and lasting impacts on an individual’s life.

Understanding the causes, symptoms, and treatments can help manage and mitigate the effects of TBIs. If you or someone you know experiences a head injury, seeking prompt medical attention is crucial for the best possible outcome.

Causes of Traumatic Brain Injury

• Falls: Falling, especially among older adults and young children, is the leading cause of TBIs.
• Motor Vehicle Accidents: Crashes involving cars, motorcycles, bicycles, and pedestrians can result in TBIs.
• Sports Injuries: Contact sports such as football, boxing, and hockey can lead to TBIs.
• Assaults: Physical violence, including domestic abuse and gunshot wounds, can cause TBIs.
• Explosive Blasts: Common in military personnel, blasts can cause severe brain injuries.

Symptoms of Traumatic Brain Injury

• Headache: Persistent or severe headaches.
• Confusion: Feeling dazed or confused.
• Dizziness: Balance problems or dizziness.
• Nausea: Nausea or vomiting.
• Memory Issues: Trouble remembering the event or what happened before/after the injury.
• Sensitivity: Sensitivity to light or noise.
• Loss of Consciousness: Extended periods of unconsciousness or coma.
• Persistent Headaches: Worsening or constant headaches.
• Repeated Vomiting: Frequent nausea or vomiting.
• Seizures: Convulsions or seizures.
• Pupil Dilation: One or both pupils dilate (get bigger).
• Slurred Speech: Difficulty speaking or slurred speech.
• Weakness/Numbness: Weakness or numbness in fingers and toes.
• Agitation: Increased confusion, restlessness, or agitation.

Treatment of Traumatic Brain Injury

• Rest and over-the-counter pain relievers are often sufficient. Monitoring for worsening symptoms is crucial.
• Immediate medical attention is necessary. Treatments can include medications to reduce pressure in the brain, surgery to repair damage or remove blood clots, and rehabilitation therapies.
