A brain injury is a serious injury that can put you at risk for disability or even death after a car accident. According to the Brain Trauma Foundation, among adults ranging in age from 1 to 44, traumatic brain injuries are the leading cause of death and disability. 

A brain injury can have a wide range of physical and mental effects. After the car crash, some of these symptoms may show up right away while others may take days or even weeks to develop. 

1. Sensory

Some of the sensory issues associated with a brain injury can include ringing in your ears, a bad taste in your mouth, blurred vision or alterations to your ability to smell. You may also experience a newfound sensitivity to sound or light. 

2. Physical

Physical brain injury symptoms that may occur following a car accident include loss of consciousness, a reoccurring headache, nausea or vomiting, problems speaking or ongoing fatigue and drowsiness. You may also experience problems sleeping, such as sleeping more than you normally do, as well as issues with your ability to balance. 

3. Cognitive

You may have a difficult time concentrating or remembering things if you have a brain injury from a car accident. Additionally, you may feel depressed or anxious and undergo multiple mood changes and mood swings. 

See a doctor right away about your cognitive, physical or sensory symptoms if they seem to be getting worse instead of better. You should also seek emergency medical care if you lose consciousness or cannot stay awake.
