Epilepsy Can Follow Traumatic Brain Injury
It’s Brain Injury Awareness Month and March 26 was Purple Day for Epilepsy Awareness! Did you know that traumatic brain injury (TBI) can cause epilepsy?
A traumatic brain injury (TBI) can happen to anyone, especially young children and older adults. TBIs can range from mild TBIs (such as concussions) to severe, life-threatening injuries. They can cause problems such as changes in:
- Thinking and memory;
- Sensations and balance;
- Language, such as talking and understanding; and
- Emotions, such as depression, anxiety, or aggression.1
TBIs can also cause epilepsy.
Epilepsy is a broad term used for a brain disorder that causes re-occuring seizures. There are many types of epilepsy and there are also many different kinds of seizures. TBIs can cause a seizure right after the injury happens or even months or years later. Researchers agree that the more severe the TBI, the greater the chance the person may develop epilepsy.2 Factors such as age and other medical conditions also influence the chance a person may develop epilepsy after a TBI.
The terms post-traumatic epilepsy (PTE) and post-traumatic seizures (PTS) are both used to describe seizures that happen because of a TBI.3 In 2013 there were over 280,000 hospitalizations for TBI in the US.4 A CDC-funded study found that among people aged 15 years and older, about 1 out of 10 developed epilepsy in the 3 years following a TBI that required hospitalization.2
- Learn the signs and symptoms of TBI and when to seek medical care.
- Take the CDC's HEADS UP training to learn how to recognize, respond to, and minimize the risk of concussion or TBI if you're a parent, coach, child care provider, or school professional.
If you or someone you care for has a head injury, here's what you need to know:
- Seek medical attention and share information about TBI signs and symptoms.
- Talk to the doctor about the risk for having seizures or developing epilepsy after a TBI.
- Learn to recognize the signs of a seizure. Sometimes it can be hard to tell. Some seizures cause a person to fall, cry out, shake or jerk, and become unaware of what's going on around them. Other seizures can make a person appear confused, make it hard for them to answer questions, twitch, or cause the person to feel like they taste, see or smell something unusual.
- Learn first aid so you are prepared if someone has a seizure.
To prevent TBIs that may cause epilepsy, protect your brain from injury. For example:
- Use seat belts and properly installed car safety seats every time you drive or ride in a motor vehicle.
- Never drive while under the influence of alcohol or drugs.
- Wear a helmet when playing certain sports and riding bikes, horses, motorcycles, or all-terrain vehicles.
- Prevent falls, especially in older adults and young children.
