Brain injuries have numerous causes, from car crashes to slip-and-fall accidents. No matter the underlying cause, a serious brain injury can affect you for years to come. Depending on the severity of the injury and where it occurs, there is also a risk of complications.

As explained by Brainline, some of the following complications can have a lasting effect on your health and wellness. Some are even life-threatening, which is why immediate medical attention is a must for all moderate to severe injuries.


When the brain is damaged, it may become active on its own. This is known as a seizure, which typically causes tremors and other effects throughout the body. Seizures can impact thinking, depending on what area of the brain was injured. Seizures are most likely to occur when a person experiences a penetrating head injury, but they can also result from closed injuries as well.

Blood clots

Head injuries also increase your risk of deep vein thrombosis (DVT), which is when a blood clot forms within the arms or legs. Further damage can occur if one of these clots breaks free and makes it to the lungs.


When signals going from the brain to other parts of the body are interrupted, spasticity can result. Affected muscles contract and are difficult, or even impossible, to straighten out. The result is a painful condition that also makes mobility challenging. People with spasticity usually require ongoing physical therapy, including stretching exercises, as well as medications for treatment.


The skull is unable to flex, so a build up of pressure is a major medical issue. Hydrocephalus occurs when fluid builds up in the brain, which leads to symptoms like head pain. When fluid build up is significant, surgeons may need to place a shunt in the brain to decrease pressure.
