Frontal Lobe Seizures
Medically reviewed by Drugs.com. Last updated on Oct 1, 2023.
What is a frontal lobe seizure?
A seizure is an abnormal burst of electrical activity in your brain. A frontal lobe seizure starts in the frontal lobe of the brain. This is located at the front of the brain, behind your forehead. This part of the brain controls many functions. A frontal lobe seizure is called a focal seizure because it starts in one part of your brain. The seizure may last under 30 seconds and may happen while you sleep. It may be simple or complex. Simple means you stay aware of your surroundings. Complex means you lose awareness. The seizure can become a generalized tonic-clonic (grand mal) seizure. This may cause you to have convulsions.
What increases my risk for frontal lobe seizures?
- Epilepsy (condition that causes repeated seizures)
- A family history of epilepsy, especially autosomal dominant nocturnal frontal lobe epilepsy
- A history of febrile seizures (caused by a high fever)
- A traumatic brain injury or a brain tumor
- An infection in your brain, such as meningitis
- Scarring in part of your brain from a past injury, including birth injuries
- Problems with blood vessels in your brain, or a stroke
What are the signs and symptoms of a frontal lobe seizure?
- Head and eye movement to one side
- Trouble speaking, or yelling profanities
- Laughing for no reason
- Body postures that are stiff or look like you are fighting someone
- Rocking your body or thrusting your hips
- Staring and not responding when spoken to
- Making motions like you are chewing or swallowing, or you taste something that is not real
- Fear or mood swings
How is a frontal lobe seizure diagnosed?
Your healthcare provider will ask about your health conditions and what medicines you take. Describe how you felt before and after the seizure. Include details about the side of your body that seemed more affected. Tell the provider how close together the seizures were if you had more than one. Your healthcare provider will ask for a detailed description of each seizure. If possible, bring someone with you who saw you have a seizure. You may also need any of the following:
- An EEG records the electrical activity of your brain. It is used to find changes in the normal patterns of your brain activity. A frontal lobe seizure may not show up on an EEG. Your healthcare provider may make a video recording while you sleep. The combination of EEG and video recording may help diagnose a frontal lobe seizure.
- CT or MRI pictures may be used to check for abnormal areas or tumors. You may be given contrast liquid to help your brain show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
- A PET scan is used to see activity in areas of your brain. You are given radioactive material that helps healthcare providers see the activity better.
- A SPECT scan uses radioactive material to find where the seizure started in your brain. This scan may be done if other scans do not show where the seizure started.
How is a frontal lobe seizure treated?
The goal of treatment is to try to stop your seizures completely. You may need any of the following:
- Medicines will help control your seizures. You may need medicine daily to prevent seizures or during a seizure to stop it. Do not stop taking your medicine unless directed by your healthcare provider.
- Surgery may help reduce how often you have seizures if medicine does not help. Ask your healthcare provider for more information about surgery.
What can I do to prevent a seizure?
You may not be able to prevent every seizure. The following can help you manage triggers that may make a seizure start:
- Take your antiepileptic medicine every day at the same time. This will also help prevent medicine side effects. Set an alarm to help remind you to take your medicine every day.
- Manage stress. Stress can be a trigger for seizures. Exercise can help you reduce stress. Talk to your healthcare provider about exercise that is safe for you. Illness can be a form of stress. Eat a variety of healthy foods and drink plenty of liquids during an illness. Talk to your healthcare provider about other ways to manage stress.
- Set a regular sleep schedule. A lack of sleep can trigger a seizure. Try to go to sleep and wake up at the same times every day. Keep your bedroom quiet and dark. Talk to your healthcare provider if you are having trouble sleeping.
- Limit or do not drink alcohol as directed. Alcohol can trigger a seizure, especially if you drink a large amount at one time. A drink of alcohol is 12 ounces of beer, 1½ ounces of liquor, or 5 ounces of wine. Talk to your healthcare provider about a safe amount of alcohol for you. Your provider may recommend that you do not drink any alcohol. Tell him or her if you need help to quit drinking.
What can I do to manage frontal lobe seizures?
- Keep a seizure diary. This can help you find your triggers and avoid them. Possible triggers include illness, lack of sleep, hormonal changes, alcohol, drugs, lights, and stress. Write down the dates of your seizures, where you were, and what you were doing. Include how you felt before and after the seizure.
- Record any auras you have before a seizure. An aura is a warning sign that you are about to have a seizure. The aura may happen seconds before a seizure, or up to an hour before. You may feel, see, hear, or smell something. Examples include part of your body becoming hot. You may see a flash of light or hear something. You may have anxiety or déjà vu. If you have an aura, include it in your seizure diary.
- Ask what safety precautions you should take. Talk with your healthcare provider about driving. You may not be able to drive until you are seizure-free for a period of time. You will need to check the law where you live. Also talk to your healthcare provider about swimming and bathing. You may drown or develop life-threatening heart or lung damage if you have a seizure in water.
- Carry medical alert identification. Wear medical alert jewelry or carry a card that says you had a seizure. Ask your healthcare provider where to get these items.
What do I need to know about stopping my medicine?
Your healthcare provider can help you understand and make decisions about continuing or stopping antiseizure medicines. Do not stop taking the medicine until your provider says it is okay. You may need to be seizure free for 18 to 24 months before you can stop your medicine. Seizures might happen again while you stop taking the medicine, or after you stop. Rarely, these seizures no longer respond to medicines. Tests such as an EEG may be useful in helping you and your provider make medicine decisions.
