Traumatic Brain Injury (TBI)
A traumatic brain injury (TBI) after a car accident is damage to the brain caused by a blow, jolt, or rapid acceleration and deceleration of the head - it can occur without any visible head wound. TBIs range from mild concussions to severe, life-altering brain damage, and effects may not fully appear for days or weeks after the accident.

Some symptoms appear immediately; others develop hours or days after the accident. Seek medical evaluation promptly even if you feel okay.
- Headache or pressure in the head
- Loss of consciousness (brief or extended)
- Confusion, disorientation, or feeling 'foggy'
- Memory loss - before, during, or after the injury
- Nausea or vomiting
- Sensitivity to light and noise
- Sleep disturbances - difficulty sleeping or sleeping excessively
- Mood changes, irritability, anxiety, or depression
- Seizures in moderate-to-severe cases
Serious injuries can have lasting effects on your health, work, and daily life. Understanding these possibilities matters for your recovery and legal options.
- Post-concussion syndrome - symptoms persisting weeks or months
- Chronic traumatic encephalopathy (CTE) from repeated brain trauma
- Cognitive impairment affecting memory, attention, and executive function
- Personality changes and emotional dysregulation
- Increased risk of Alzheimer's disease and other neurodegenerative conditions
- Epilepsy or seizure disorder
- Permanent physical disability in severe cases
- Inability to return to work or maintain prior level of function
Treatment options vary based on severity. Follow your healthcare provider's recommendations and document all treatment - it is important evidence for your claim.
- Immediate emergency stabilization for severe TBI
- CT scan and MRI imaging to assess injury extent
- Cognitive rest and graduated return to activity for mild TBI
- Medication for symptoms including headache, nausea, seizures, and mood
- Cognitive rehabilitation therapy
- Speech and language therapy for communication impairments
- Occupational therapy for daily function recovery
- Psychological counseling for mood and emotional effects
- Long-term neurological monitoring and follow-up

Frequently asked questions
Symptoms of a TBI can include headache or pressure in the head, loss of consciousness (brief or extended), confusion or disorientation, and memory loss before, during, or after the injury. Nausea, sensitivity to light and noise, sleep disturbances, mood changes, and seizures in moderate-to-severe cases are also common. See a doctor promptly after any head impact, since some symptoms take hours or days to appear.
Among the most common causes of TBI are car, truck, and motorcycle accidents, pedestrian accidents involving vehicle impact, slip and fall accidents (especially head impacts), and construction site accidents from falls or struck-by objects. Sports and recreational head impacts and workplace accidents involving blunt force or falls are also common causes.
Treatment depends on severity. Severe TBI needs immediate emergency stabilization along with CT or MRI imaging to assess the injury, while mild TBI is often managed with cognitive rest and a graduated return to activity. Recovery can also involve medication for headache, nausea, seizures, or mood, plus cognitive rehabilitation, speech and language therapy, and occupational therapy.
Long-term effects of TBI can include post-concussion syndrome with symptoms lasting weeks or months, cognitive impairment affecting memory and attention, personality changes, and epilepsy or seizure disorder. Severe cases can result in permanent physical disability or the inability to return to work, and repeated trauma raises the risk of chronic traumatic encephalopathy (CTE).
