Have you ever heard of 'Frontal Lobe Seizure' or 'Frontal Lobe Epilepsy'? Maybe you or someone you know has had this type of epilepsy. Although this may seem a bit complicated, let's talk about it simply. Because it is very important to be aware of this.
What is 'Frontal Lobe Epilepsy'?
Simply put, frontal lobe epilepsy is a seizure disorder that affects the frontal lobes , the areas behind your forehead. These frontal lobes are the largest of the four main parts of our brain. There is one on the left side and one on the right side. These are our:
- Behavior and personality
- Thinking, learning and decision-making (Cognition)
- Movements
- Talking
Controls things like.
So, in 'frontal lobe epilepsy', there is an abnormal electrical activity in the 'frontal lobes' of the brain. It is like a 'short circuit'. We call the epileptic conditions that occur due to this 'frontal lobe seizures'. These belong to the type of 'focal seizure'. That is, the epileptic condition starts in one specific area of the brain. This can start in the left 'frontal lobe' of the brain or in the right one.
Because these symptoms often occur at night , they can sometimes be mistaken for a mental illness or sleep problem. Therefore, it is very important to get an accurate diagnosis.
Are there types of 'frontal lobe epilepsy'?
Yes, there is one specific type. It is called 'autosomal dominant sleep-related hypermotor epilepsy' . It was also previously called 'autosomal dominant nocturnal frontal lobe epilepsy'. This is a type of epilepsy that occurs during sleep. This type often runs in families, meaning it can be passed down through generations.
What symptoms can be seen in this condition?
The main symptom of frontal lobe epilepsy is a brief focal seizure that starts in one area of the brain. These seizures can cause symptoms such as:
- Unusual behaviors: Things like suddenly shouting, laughing, cursing, etc. Imagine how alarmed others would be if someone who was sleeping suddenly did something like this.
- Turning the head or eyes to one side.
- Kicking your legs or making movements like riding a bicycle.
- Thrashing or convulsions.
- Uncontrolled, repetitive movements (e.g., rapid shaking of arms and legs).
- Twitching or repetitive twitching.
- Loss of consciousness or awareness of surroundings (like staring at the sky).
- Urinary or fecal incontinence.
- Muscle weakness.
- Difficulty speaking.
- Personality changes.
- Sleep problems.
These 'seizures' often occur in clusters, meaning they can occur more than two times in 24 hours. They usually occur while you are sleeping , but they can also occur while you are awake. They are also usually short-lived, lasting less than a minute.
Sometimes, before a seizure starts, you may have an 'aura' , which is an unusual sensation. These can include:
- Sudden changes in emotions: such as fear, anxiety, anger, sadness, or happiness.
- Unusual sensations: Like numbness.
- Changes in sensory perception: altered sense of smell, hearing, sight, taste, or touch.
After a frontal lobe seizure, you may experience confusion, memory loss, or muscle pain . This is called the postictal state .
What are the causes of 'frontal lobe epilepsy'?
Frontal lobe epilepsy is caused by abnormal electrical activity in your frontal lobe. Normally, the nerve cells in our brain, called neurons , send signals to each other. But in a frontal lobe seizure, these neurons fire out of control.
Common reasons that can affect this are:
- Abnormal development of the brain during the embryonic stage.
- Brain infections.
- Stroke.
- Serious head injuries (Traumatic brain injury).
- Brain tumor.
- Genetic variations.
Sometimes you may not be able to find a reason.
Is this something that comes from generations?
Yes, one type of frontal lobe epilepsy can be passed down from parents to children, but it's a bit rare. The type of sleep-related hypermotor epilepsy we talked about earlier is an autosomal dominant condition. This means that if one of the parents has this genetic variation, the child is likely to inherit it.
Who is most at risk for this condition?
Frontal lobe epilepsy can affect anyone, at any age. However, you may be at increased risk for the following reasons:
- If anyone in your family has epilepsy (biological family history).
- If you had a brain infection as a child.
- If you have had a stroke, a serious head injury, or a tumor or other damage to the frontal lobe.
- If there is a developmental delay.
- If you were born with brain abnormalities at birth.
What are the triggers for the increase in frontal lobe seizures?
'Triggers' are things that increase the likelihood of epileptic seizures. Common 'triggers' include:
- Stress.
- Flashing lights.
- Sleep deprivation.
- Substance use.
These can vary from person to person . Keeping a record of what you were doing and how you felt before a seizure started can help you identify triggers that affect you.
Are 'frontal lobe seizures' dangerous?
Frequent frontal lobe seizures can cause the following:
- Increased risk of injury.
- Status epilepticus: Seizures lasting more than five minutes. This is a life-threatening emergency.
- Sudden unexplained death in epilepsy (SUDEP): This is very rare, but it can happen.
Having seizures can often have a significant impact on your mental health and emotional well-being. So, in addition to other treatments recommended by a doctor, consider talking to a mental health counselor .
If you are having suicidal thoughts, see a doctor immediately or talk to someone you trust . There are places in Sri Lanka where you can get help for this (e.g. Sumitrayo 0112682535). Remember, you are not alone, and don't be afraid to ask for help.
How is 'frontal lobe epilepsy' diagnosed?
To diagnose frontal lobe epilepsy, your doctor will review your medical history and perform a physical exam. In addition, several tests may be ordered to confirm the diagnosis.
Diagnostic tests
Here are the tests that help diagnose 'frontal lobe epilepsy':
- MRI (Magnetic Resonance Imaging) scan: This can take detailed pictures of your brain. This can help to see if there are any tumors, lesions, or other problems that could be causing your seizures.
- EEG (Electroencephalography): This records the electrical activity of your brain. This helps to find where the seizure is starting.
- Video EEG: This involves recording your brain activity as well as your movements and behaviors. This may require an overnight stay in the hospital. Since many frontal lobe seizures occur during sleep, a sleep study may also be done.
- Stereoelectroencephalography (SEEG): In this test, a surgeon inserts electrodes into your brain. These devices can detect seizure activity deep in the brain that is not picked up by an EEG. SEEG is usually done if your seizures are not controlled by medication and if brain surgery is being considered.
- Magnetoencephalography (MEG): This test records the magnetic activity caused by the brain's electrical activity, helping to identify areas of abnormal brain activity.
In addition, the doctor may also perform neuropsychological testing to determine if the seizures are affecting brain function.
What are the treatments for this?
The main goal of treatment for frontal lobe epilepsy is to reduce the number of frontal lobe seizures you have. Your doctor may recommend treatments such as:
- Antiseizure medications
- Epilepsy surgery
- 'Neuromodulation'
Additionally, your doctor may recommend changing your diet and switching to a high-fat, low-carbohydrate diet (e.g., a 'ketogenic diet for epilepsy' ).
Antiseizure Medications for Frontal Lobe Seizures
Antiepileptic drugs can help control frontal lobe seizures. These drugs regulate the brain's electrical activity and reduce the frequency of seizures. These are usually the first line of treatment.
Your doctor will review your symptoms and prescribe the right medication for you. Before starting a new medication, they will also explain the possible side effects. Your doctor may need to change the dosage or type of medication until you find the right one for you.
Surgery for 'Frontal Lobe Seizures' (Epilepsy Surgery)
If medications don't control your frontal lobe seizures, your doctor may consider surgery to treat epilepsy. Your doctor may recommend a frontal lobe resection . This involves removing the affected part of the frontal lobe where the seizures start. It may also remove a brain tumor or other damage in that area.
Before surgery, your surgeon will use various imaging scans to create detailed maps of your brain. He or she may also surgically implant electrodes for a special type of 'stereo-EEG (SEEG)' to record from inside the brain. All of this information will help your surgical team:
- Identify the specific areas of the brain that cause seizures.
- Take care not to damage the parts of the 'frontal lobe' that control important brain functions.
Neuromodulation for frontal lobe seizures
In some cases, surgery to treat frontal lobe seizures may not be safe. In that case, your doctor may recommend a treatment called neuromodulation. This treatment uses a device implanted in the body to send electrical impulses to the brain, trying to stop a seizure before it starts.
Commonly used types of neuromodulation devices are:
- Vagus Nerve Stimulation (VNS): A surgeon implants a small device under the skin of your chest. It is connected to a wire. The wire wraps around the vagus nerve in your neck and sends pulses to that nerve. Some VNS devices can detect changes in heart rate during a seizure and send additional electrical pulses to the vagus nerve.
- Responsive Neurostimulation (RNS): RNS is a device that is implanted in your scalp. The RNS monitors your brain activity and sends electrical pulses only when it detects that a seizure is occurring.
- Deep Brain Stimulation (DBS): A surgeon implants a DBS device in your chest. Its wires are connected to electrodes implanted in your brain. A doctor programs this device and sends electrical impulses to your brain.
What is the outlook for frontal lobe epilepsy? (Outlook)
Your doctor can give you the best information about your outlook. It varies from person to person, based on many factors, such as your general health and how often you have seizures.
Medications can help control seizures in the long term. But sometimes, medications don't work well for everyone. Surgery may be another option. Although there is no cure for frontal lobe epilepsy, many people experience a reduction in seizures or complete remission after a combination of medications or surgery.
Your doctor will tell you what treatment options will help you stay safe.
When should you see a doctor?
See a doctor if you develop new symptoms or if your symptoms get worse. Make sure your treatment is working properly, and keep your doctor appointments . Tell your doctor if you have any side effects after starting a new medication.
What should I ask my doctor?
If you have frontal lobe epilepsy, you may want to ask your doctor about:
- What kind of treatment do you recommend?
- What are the side effects of the treatment?
- Is it safe to take antiepileptic drugs if I'm thinking about starting a family?
- How do I stay safe during a 'seismic'?
- Am I eligible for surgery?
Summary and things to remember
The two largest parts of our brain, the frontal lobes, have a very important role to play. But unless something goes wrong in this part of the brain, we don't really understand its value. Fortunately, there are treatment options for frontal lobe epilepsy and the seizures that result from it.
Your doctor will help you choose one or more medications that are right for you. Don't worry if medications don't work. In some cases, surgery or neuromodulation may be a better option for your brain. No matter what treatment you choose, your medical team will be there to answer any questions you may have. If you'd like, they can also recommend a support group or counseling. Remember, you're not alone on this journey!
