Can traumatic brain injuries cause seizures?

Most people with brain injuries do not have seizures. However, seizures are a potential problem that some people who have suffered a traumatic brain injury (TBI) must deal with.

Seizures are an abnormal electrical disturbance in the brain. They can cause symptoms such as strange movements of your body, unresponsiveness, strange smells, sounds, tastes or visual images and not being able to speak. During a seizure, a TBI victim will be unable to control the symptoms and may bite his or her tongue or have a bowel or bladder accident. Seizures may be controlled with medications.

The cause of your brain injuries may affect your risk of having seizures later. Approximately 65 percent of people whose brains are injured by bullet wounds will have seizures, for example. About 20 percent of people suffer a seizure if they have a closed head injury that results in bleeding between the brain and the skull. More than 35 percent of brain injury victims who require two or more brain surgeries will have seizures.

In patients with TBI, the type of seizure is determined in part by when they occur. Seizures that occur in the first week after a brain injury are called early post-traumatic seizures. In most cases, they occur only once, but about ¼ of people will have another seizure later. Seizures that occur more than a week after a brain injury are called late post-traumatic seizures. About 80 percent of people with these seizures will experience another one.

Seizures can have a devastating impact on the life of a brain injury victim. If you or a loved one has suffered a seizure from a brain injury, an experienced Los Angeles attorney can help evaluate your situation and bring in experts to show the true impact of the brain injury on your life.
