When you get into a car accident, you could sustain a traumatic brain injury after a jolt or blow to your head. The Brain Trauma Foundation states that every year, approximately 2.5 million people sustain some type of brain injury. 

Depending on its severity, a TBI can result in death or long-term complications. You should familiarize yourself with the symptoms of a TBI, so you can seek treatment as soon as possible. 

Physical signs

If you have a brain injury from a car accident, you may lose consciousness for several seconds to a few minutes. You may also experience headaches, nausea, fatigue or drowsiness, problems sleeping or sleeping more than usual and loss of balance. Other physical complications can include seizures, fluid buildup in the brain and vertigo. 

Sensory signs

A brain injury can make you more sensitive to lights and sounds. Other sensory issues can include blurred vision, a bad taste in your mouth, changes with your ability to smell and persistent ringing in your ears. 

Cognitive signs

You may have a hard time remembering things and concentrating on tasks with a TBI. You may also experience sudden mood changes and feel continuously depressed or anxious after the accident. Additionally, it may be hard to do multiple activities at once, plan future activities or make decisions with a brain injury. 

You may notice these sensory, cognitive and physical signs immediately after the car accident. Other symptoms may show up several days or even several weeks following the traumatic event.
