Mild traumatic brain injuries such as concussions are serious. Symptoms can take a few days to appear, so it is important to seek medical care right away even if you do not have symptoms after a head impact.
Learn more about TBI symptoms so you know when to get help for yourself or a family member.
Mild TBI symptoms
Symptoms of mild TBI and concussion can be physical, emotional or mental. They may include:
- Light or noise aversions
- Dizziness or balance problems
- Feeling tired or fatigued with no energy
- Headaches
- Nausea/vomiting
- Vision problems
- Concentration problems
- Issues with short-term or long-term memory
- Difficulty thinking clearly
- Anxiety
- Mood swings or irritability
- Sadness
- Difficulty sleeping
It may be hard to recognize a problem as people overlook many minor concussion symptoms.
Dangerous symptoms
A serious blood clot can develop with TBI. Seek immediate attention for:
- Headache that worsens
- Weakness
- Numbness
- Decreased coordination
- Convulsions or seizures
- Repeat vomiting
- Unusual behavior
- Slurred speech
- One pupil larger than the other
- Loss of consciousness or inability to awaken
Get children immediate medical attention for a bump, blow or jolt to the head or body. They may refuse to eat or nurse, cry uncontrollably, and experience any of the other symptoms listed above.
While not every TBI has long-lasting effects or requires medical treatment, delaying care can worsen outcomes. Call 911 or go to an emergency department if symptoms are present, or see a doctor after a head injury that does not result in symptoms. Doing so can prevent lifelong injury after a fall or auto accident.
