On Behalf of | Nov 7, 2022 | Personal Injury

Motor vehicle accidents are a leading cause of traumatic brain injuries (TBI). The Brain Trauma Foundation estimates that car crashes contribute to 20 percent of TBIs in the United States.

If you recently suffered from a car accident, continue reading to learn about the symptoms of a traumatic brain injury. Sometimes, it takes a few days for the signs to appear.

Mild TBI

Mild TBIs have signs you might initially dismiss. However, you should see a doctor immediately if you notice any of the following symptoms:

  • Nausea
  • Vomiting
  • Abnormal fatigue
  • Problems speaking
  • Headaches
  • Dizziness

Besides physical symptoms, the Mayo Clinic says to watch out for sensory signs. Ringing ears, blurred sight and an unpleasant taste in your mouth might indicate a TBI. Cognitive symptoms include feeling confused, losing consciousness, problems remembering, sudden mood changes, and problems sleeping or sleeping more than usual.

Severe TBI

Severe TBIs may include the same symptoms as mild TBI. However, you might have a severe brain injury if you notice the following:

  • Continuous and worsening headaches
  • Seizures
  • Convulsions
  • Dilated pupils
  • Pins and needles in your extremities
  • Lack of coordination

Cognitive symptoms include slurred speech, aggressive behavior or overwhelming confusion.


Seek medical attention immediately if you suffer from any of the symptoms described above. If you neglect medical treatment, you may experience several complications such as a vegetative state, coma, minimally conscious state or brain death.

Traumatic brain injuries are one of the worst outcomes of a motor vehicle accident. Do not assume that your symptoms will disappear, and find a medical practitioner specializing in head injuries.
