Traumatic Brain Injury

A Traumatic brain injury (TBI) is a brain injury caused by an outside force. A blow to the head, a bump, or jolt to the head or body can cause it, although not all bumps or jolts to the head cause a TBI. An object entering the brain can also cause a TBI. TBIs are sometimes called brain injuries or head injuries. TBIs can be serious injuries that negatively affect how the brain works and can make everyday tasks more difficult.

In 2023, TBIs were involved in nearly 13,300 emergency department visits, over 4,260 non-fatal hospitalizations, and about 1,500 deaths occurred among Wisconsin residents.
