Temporal lobe seizures begin in the temporal lobes of the brain. These areas process emotions and are important for short-term memory. Symptoms of a temporal lobe seizure often affect these functions . Some people have odd feelings during the seizure, such as joy, deja vu or fear.
Temporal lobe seizures are sometimes called focal seizures with impaired awareness. Some people are aware of what's going on during the seizure. People who have more-intense seizures might look awake but won't respond to what's around them. Their lips and hands may make motions over and over.
The cause of temporal lobe seizures often isn't known. But it may stem from a scar in the temporal lobe. Temporal lobe seizures are treated with medicine. Some people who don't respond to medicine may have surgery.
An odd feeling called an aura may happen before a temporal lobe seizure. An aura acts as a warning. Not everyone who has temporal lobe seizures has auras. And not everyone who has auras remembers them.
The aura is the first part of a focal seizure before a loss of consciousness.
Examples of auras include:
Sometimes temporal lobe seizures keep people from responding to others. This type of temporal lobe seizure most often lasts 30 seconds to 2 minutes.
Symptoms of a temporal lobe seizure include:
After a temporal lobe seizure, you may:
Sometimes, what starts as a temporal lobe seizure becomes a generalized tonic-clonic seizure. This type of seizure causes shaking, known as convulsions, and loss of consciousness. It also is called a grand mal seizure.
Call 911 or your local emergency number if:
For a first seizure, see a healthcare professional.
Seek medical advice if:
Often, experts don't know the cause of temporal lobe seizures. But they can be a result of the following factors:
During waking and sleeping, the brain cells have electrical activity. A burst of electrical activity in many brain cells may cause a seizure.
If this burst happens in just one area of the brain, the result is a focal seizure. A temporal lobe seizure is a focal seizure that starts in one of the temporal lobes.
There are several risk factors for temporal lobe seizure. They pose the most risk if they happen early in life. These risk factors include:
Over time, repeated temporal lobe seizures can cause the part of the brain involved in learning and memory to shrink. This area of the brain is called the hippocampus. The loss of brain cells in the hippocampus may cause memory problems.
After a seizure, your healthcare professional reviews your symptoms and medical history. You may have tests to find the cause of your seizure. Knowing the cause helps show how likely it is that you'll have another seizure.
Tests may include:
Not everyone who has a seizure has another one. Your healthcare professional may decide not to start treatment until you've had more than one.
Seizure treatment aims to find the best therapy to stop your seizures with the fewest side effects.
Many medicines treat temporal lobe seizures. But many people can't manage seizures fully with medicines alone. Side effects are common. They can include tiredness, weight gain and dizziness.
Discuss possible side effects with your healthcare professional when thinking about treatments. Also ask what effect your seizure medicines may have on other medicines you take. For instance, some antiseizure medicines can affect how well birth control pills work.
Following a ketogenic diet can improve seizure management. A ketogenic diet is high in fat and very low in carbohydrates. But it can be hard to follow because it allows only a very limited number of foods.
Other versions of a high-fat, low-carbohydrate diet also may be helpful but not work as well. These diets include low glycemic index and Atkins diets. Experts are still studying these diets.
When antiseizure medicines don't work, there are other treatments, including:
Surgery. Epilepsy surgery is a procedure to reduce seizures and improve the quality of life of people who have epilepsy. Surgeons often do this with open surgery to remove the area of the brain where seizures begin.
Sometimes, surgeons may be able to use MRI-guided laser therapy. This is a less- invasive way to destroy the area of tissue that causes seizures.
Surgery works best if you have seizures that always start in the same place in the brain. Most often, you won't have surgery if your seizures come from more than one area of the brain.
You also might not be able to have surgery if your healthcare team can't find where the seizures start. Surgery also may not be an option if your seizures come from a part of the brain that affects speech, thinking, movement, memories and other important functions.
People who've had seizures can most often have healthy pregnancies. But some medicines used to treat seizures sometimes can cause health conditions that are present at birth.
Valproic acid is a medicine for generalized seizures that has been linked with cognitive issues and neural tube defects, such as spina bifida, in babies. The American Academy of Neurology recommends against using valproic acid during pregnancy because of risks to babies.
Talk with your healthcare professional about the risks of antiseizure medicines, including the risk of health conditions present at birth. Make a plan with your health professional before you get pregnant. Pregnancy can change the way you need to take your medicine.
Some people may need to change the dosage of seizure medicine before or during pregnancy. The goal is to be on the lowest dose of the safest seizure medicine that manages seizures.
Some antiseizure medicines keep birth control from working as well. Check with your healthcare professional to see whether your medicine affects your birth control. You may need to try other forms of birth control.
Here are some steps you can take to help manage seizures:
Most often, seizures don't result in serious injury. But injury is possible if you have recurrent seizures. These steps can help you avoid injury during a seizure:
It's helpful to know what to do if you see someone having a seizure. If you're at risk of having seizures in the future, give this information to family, friends and co-workers. Then they'll know what to do if you have a seizure.
To help someone during a seizure:
Stress due to living with a seizure condition can affect your mental health. Talk with your healthcare professional about your feelings. Look for ways to find help.
Your family can provide much-needed support. Tell them what you know about your seizures. Let them know they can ask you questions. Ask them about their worries.
Talk with your supervisor about your seizures and how they affect you. Discuss what you need your supervisor or co-workers to do if you have a seizure at work. Talk with your co-workers about seizures. This will help them understand your condition and give you more support.
Reach out to family and friends. Ask your healthcare professional about local support groups or join an online support community. Don't be afraid to ask for help. Having a strong support system is vital to living with any medical condition.
Sometimes seizures need medical help right away. There isn’t always time to prepare for an appointment.
But you may see your main healthcare professional or be sent to a specialist. You might see a specialist trained in brain and nervous system conditions, called a neurologist. Or you might see a neurologist trained in epilepsy, known as an epileptologist.
Here's some information to help you get ready for your appointment.
For seizures, some basic questions to ask include:
Be sure to ask all the questions you have.
A healthcare professional is likely to ask you questions, such as:
