Traumatic brain injury (TBI) is more than just a bump on the head. It’s an injury that affects how the brain works and can lead to short- or long-term health problems.
TBIs may be caused by a bump, blow, or jolt to the head, or by a penetrating injury to the head (such as from a gunshot).
Some injuries are mild, like a concussion. Others are moderate or severe injuries that may require hospitalization, rehabilitation, and ongoing support.
Common causes of TBIs include:
- Firearms
- Falls
- Motor vehicle accidents
- Being hit (sports injuries, assaults)
Falls are especially important to highlight because they account for a large share of TBI-related hospitalizations.
Traumatic Brain Injuries in Virginia
In 2024, Virginia had almost 6,000 hospitalizations for TBI.
Older adults are more likely to be hospitalized and die from a TBI compared with other age groups. TBIs may also be missed or misdiagnosed in older adults because symptoms can overlap with other conditions that are more common with aging, including dementia. If an older adult falls—especially if they hit their head or are taking blood thinners—getting checked by a healthcare provider is a smart and often time-sensitive step.
Concussion
A concussion is a mild type of TBI that changes the way the brain normally works.
A concussion is caused by a bump, blow or jolt to the head. It can also be caused by a blow to the body that causes the head and brain to move rapidly back and forth.
It’s important to know that a concussion can occur without a loss of consciousness.
Some symptoms may appear right away, while others may not appear for hours or days after the injury. Symptoms generally improve over time. Most people with a concussion feel better within a couple of weeks.
Common concussion symptoms can include:
- Headache
- Balance problems or dizziness
- Nausea/Vomiting (especially early on)
- Sensitivity to light or noise
- Blurred vision or double vision
- Feeling “dazed”, sluggish, foggy or groggy
- Difficulty concentrating or remembering
- Sleep changes (sleeping more/less, trouble falling asleep)
- Mood changes (feeling irritable, sad, nervous or more emotional
- Trouble thinking or concentrating
- Will not stop crying and are inconsolable (children only)
- Will not nurse or eat (children only)
With proper care, most people can return to work, school, and other activities within a few days or weeks, but some people will have symptoms for months or longer. Follow-uping up with a healthcare provider is critical if symptoms linger.
When to seek emergency care (Danger Signs)
Call 911 or go to the emergency department right away if someone has a bump/blow/jolt to the head and then develops danger signs such as:
- A headache that gets worse and does not go away
- Repeated vomiting
- Weakness, numbness, decreased coordination, seizures/convulsions
- Slurred speech or unusual behavior (confusion, agitation, inability to recognize people/places)
- One pupil larger than the other
- Increasing drowsiness, inability to wake up, or loss of consciousness
Small Actions Can Make a Big Difference
Everyday steps can help reduce the risk of brain injury:
In vehicles
- Wear a seat belt every trip and use the correct car seat/booster for children
In sports and recreation
- Wear a properly fitted helmet for biking and sports where helmets are recommended.
- Follow safety rules and learn the signs and symptoms of concussion.
Preventing falls—especially for older adults
- Make the home safer (remove tripping hazards, add handrails/grab bars, improve lighting).
- Stay physically active to maintain strength and balance.
- Review medications with a provider (some can increase fall risk).
- Keep vision prescriptions up to date.
