Car accident injuries are not always evident. Some injuries have delayed symptoms and will only be observed days, weeks, or months after the accident. Not all the symptoms of a traumatic brain injury are not immediately seen.
If you experience any dizziness, headache, blurry vision, and nausea and vomiting within hours, days, or months of the accident, then you have a mild traumatic brain injury. Other symptoms include disorientation, incoherent speech, sleeping more than usual, difficulty sleeping, light sensitivity, memory problems, and mood swings.
After the accident, if you lost consciousness for 20 minutes to 6 hours, it is likely that you have a moderate traumatic brain injury. You may also experience repeated vomiting, escalating headaches, and convulsions or seizures. Some clear fluid may also drain from your ears and nose.
If you lost consciousness for more than 6 hours after the accident, with a Glasgow coma scale of 3 to 8, you have a severe traumatic brain injury. The other symptoms of severe traumatic brain injury are the same as the mild traumatic brain injury but are more serious in intensity and are experienced for longer time periods.
For your own safety, it is best to seek medical attention immediately if you experience any of the symptoms after getting in a car accident, no matter how much time has passed since.
