Traumatic brain injury symptoms you should never ignore

On Behalf of | Dec 26, 2025 | Car Accidents |

We often associate traumatic brain injuries (TBIs) with sports. Therefore, they’re one of the most overlooked injuries following a motor vehicle collision. 

TBIs can occur even when there’s no direct blow to the head, and their symptoms are frequently delayed, subtle or mistaken for stress or shock. Ignoring the warning signs of a TBI can lead to long-term health problems and delayed treatment can complicate an injury claim.

How car accidents cause brain injuries

A TBI occurs when a sudden, violent force disrupts normal brain function. Car crashes are one of the leading causes of TBIs and can happen when the head strikes a window, steering wheel or airbag. It can also result from the brain moving within the skull during rapid acceleration or deceleration. 

It’s crucial to understand that a TBI doesn’t always result in losing consciousness.

Symptoms of a TBI don’t always immediately appear. Instead, they can come on gradually over hours, days or weeks. You need to seek immediate medical attention if you experience any of the following:

  • Persistent headaches or a feeling of pressure inside the head
  • Dizziness
  • Nausea or vomiting
  • Bothered by light and sound
  • Fatigue

In addition to physical symptoms, a TBI can result in cognitive symptoms and behavioral changes, such as:

  • Difficulty concentrating
  • Memory problems
  • Confusion
  • Irritability
  • Mood swings
  • Difficulty controlling emotions

If these symptoms aren’t treated promptly, there could be lifelong consequences, including difficulty maintaining employment and a reduced quality of life. Furthermore, medical records show the direct link between the car accident and brain injury. Delaying treatment can give insurance companies an excuse to argue that your symptoms were unrelated or not serious.

After a car accident, you may be facing months of recovery. A legal professional can help ensure you get the care and compensation you deserve.
