Common Signs of a Traumatic Brain Injury

Anyone suffering a head injury runs the risk of developing traumatic brain injury. If you or anyone else has been in an accident where you suspect a brain injury might have been involved, don't forget to look for the signs of traumatic brain injury (TBI).

We’ve listed all the possible signs and symptoms of TBI for adults and children so you can take steps before anything goes wrong. But before that, let’s learn what exactly traumatic brain injury means.

What is a Traumatic Brain Injury?

A forceful or violent blow, strike, or jolt to the head or body may cause traumatic brain injury. TBI symptoms can differ for every person, and children usually experience or express these signs differently than adults.

Signs of a Traumatic Brain Injury

You might experience mild to moderate or severe symptoms of TBI. Typically, people with mild symptoms feel better after a few weeks, and their symptoms reduce gradually. On the contrary, serious to moderate injuries cause long-term complications or even death.

The signs of TBI aren’t limited to physical damages. The symptoms can also be sensory, behavioral, or mental. Below we’ve assembled all the potential traumatic brain injury symptoms for you.
