Frontal Lobe Seizures

Your brain is divided into four sections (lobes) on each side. The front part, called the frontal lobe, is crucial for thinking, planning, and doing things on purpose. The parietal lobe helps you understand sensations like temperature, taste, touch, and movement. The occipital lobe is all about sight. Finally, the temporal lobe helps you remember things and connect those memories to what you taste, hear, see, and feel.

Sometimes, groups of brain cells send out sudden bursts of electrical signals. This is called epilepsy, and it can cause uncontrolled movements, known as seizures. When seizures start in the front part of the brain (the frontal lobe), we call them frontal lobe seizures, or frontal lobe epilepsy.

Since the frontal lobe is a big and important part of the brain, frontal lobe seizures can cause unusual symptoms. These symptoms might be mistaken for problems with mental health or even sleep disorders, especially since seizures can happen during sleep. For example, someone might seem confused or act strangely during a seizure, which could be misinterpreted.

A number of things can cause frontal lobe seizures, including changes in the brain tissue, infections, injuries, strokes, tumors, or other problems.

Thankfully, there are ways to manage frontal lobe seizures. Doctors often prescribe medicine to help control them. If medicine isn't enough, surgery or electrical stimulation of the brain might be considered. These treatments aim to reduce or stop the seizures.

Frontal lobe seizures are brief, usually lasting less than 30 seconds. Many people recover quickly afterward. These seizures can cause a variety of symptoms.

Possible symptoms include:

• Head and eye movement: The person's head and eyes might turn to one side.
• Communication problems: They might not respond to others or have trouble speaking. This could be temporary.
• Unusual sounds: Sometimes, people experience loud, sudden sounds like screams, which might include inappropriate words (like swear words) or even laughter.
• Unusual body positions: The person's body might take on unusual postures. A common example is one arm extended straight out while the other is bent in, similar to a person fencing.
• Repetitive movements: They might rock back and forth, pedal their legs like they're riding a bicycle, or thrust their hips.

If you or someone you know is experiencing any of these symptoms, it's important to see a doctor. If a seizure lasts longer than five minutes, call 911 or your local emergency number immediately. Seeking medical attention is vital for proper diagnosis and treatment. A doctor can help determine the cause of the seizure and recommend appropriate steps.

If you have symptoms that might be a seizure, see a doctor. If you see someone having a seizure that continues for more than five minutes, call 911 or your local emergency services immediately.

Problems in the frontal part of your brain can sometimes cause seizures. These problems can arise from various factors, including:

• Tumors: Growths in the brain can put pressure on the frontal lobes, leading to seizures.
• Strokes: Blocked blood flow to the frontal lobes can damage brain tissue, triggering seizures.
• Infections: Infections in the brain, like meningitis, can cause inflammation and seizures in the frontal lobes.
• Head injuries: A blow to the head can injure the frontal lobes and increase the risk of seizures.

A specific type of epilepsy, called autosomal dominant nocturnal frontal lobe epilepsy, is linked to problems in the frontal lobes. This type usually causes short seizures that happen mostly during sleep. If one parent has this condition, there's a 50% chance a child will inherit it. This means that if a parent has this specific type of epilepsy, there's a good chance their child could also develop it.

In about half of the cases of frontal lobe epilepsy, doctors don't know what caused the seizures. The underlying reason for these seizures remains unknown.

Things that can raise your risk of frontal lobe seizures:

• Family history: If someone in your family has had seizures or brain problems, you might have a higher chance of getting them too. This is because some types of seizures can run in families, meaning certain genes or patterns of brain development might be involved.

• Head injuries: A serious blow to the head can sometimes damage the frontal lobe, increasing the risk of seizures later on. This damage can affect how the brain works and make it more prone to abnormal electrical activity.

• Brain infections: Infections like meningitis or encephalitis can inflame the brain and cause damage, which can trigger seizures. Inflammation disrupts normal brain function and can lead to abnormal electrical activity.

• Brain tumors: Tumors growing inside the brain can put pressure on the frontal lobe and disrupt its normal activity. This pressure can trigger seizures.

• Blood vessel or tissue abnormalities: Sometimes, blood vessels or brain tissue might develop in unusual ways. These abnormalities can interfere with how the brain works, making seizures more likely. Examples could include blood clots, aneurysms, or malformations.

• Strokes: A stroke occurs when blood flow to the brain is interrupted. This can damage the frontal lobe and increase the risk of seizures. The damage from a stroke can affect the brain's electrical signals, leading to seizures.

Frontal lobe seizures can lead to several serious problems:

Prolonged Seizures (Status Epilepticus): Frontal lobe seizures often happen in groups or clusters. This can sometimes trigger a condition called status epilepticus, where the seizures go on much longer than normal. If seizures continue without stopping, they can cause lasting brain damage or even death. It's crucial to remember that any seizure lasting more than five minutes is a medical emergency. If you see someone having a seizure that lasts this long, call 911 or get immediate medical help.

Injury: The movements during a frontal lobe seizure can sometimes hurt the person having the seizure. These seizures can also lead to accidents. For example, if someone has a seizure while driving or swimming, there's a risk of injury or even drowning.

Sudden Unexpected Death in Epilepsy (SUDEP): People with epilepsy have a higher chance of dying suddenly than people without epilepsy. Doctors don't fully understand why this happens, but possible causes include problems with the heart or breathing, possibly linked to genetic factors. The best way to potentially reduce the risk of SUDEP is to effectively control seizures with medication as much as possible.

Diagnosing frontal lobe epilepsy can be tricky because its symptoms can be similar to mental health issues or sleep problems like night terrors. Sometimes, the symptoms might actually be caused by seizures starting in a different part of the brain.

To figure out if someone has frontal lobe epilepsy, a doctor will carefully review their symptoms and medical history. A physical exam is also necessary. Blood tests might be done to look for other health problems that could be causing the seizures.

Doctors will often perform a neurological exam. This exam checks different parts of the body to look for any problems. They'll test things like:

• Muscle strength: How strong are the muscles?
• Sensory skills: How well can the person feel things?
• Hearing and speech: Are there any issues with hearing or speaking?
• Vision: Is there any problem with vision?
• Coordination and balance: How well does the person coordinate their movements and balance themselves?

Several tests can help pinpoint the cause of the seizures:

• Brain scans (MRI): A detailed picture of the brain, called an MRI, can sometimes show where the seizures are originating. An MRI uses a powerful magnet and radio waves to create detailed images of the brain's soft tissues. The person lies on a narrow table that slides into a long tube. The test usually takes about an hour. Some people feel anxious in enclosed spaces, and medicine can be given to help them relax. The MRI itself is not painful.

• Electroencephalogram (EEG): An EEG measures the electrical activity in the brain. Small metal discs (electrodes) are attached to the scalp. EEGs can help diagnose some types of epilepsy, but they might not detect frontal lobe epilepsy.

• Video EEG: Sometimes, a video EEG is needed. This involves wearing an EEG machine and being videotaped, often overnight in a sleep clinic. This allows doctors to see what happens during a seizure and how the brain's electrical activity changes at the same time. This helps doctors match up the physical seizure events with the electrical activity on the EEG.

It's important to remember that these tests are used together to build a complete picture of the person's health and help doctors make the best diagnosis possible.

Treating Frontal Lobe Seizures: More Options Available

Over the past decade, more treatments are available for seizures that start in the frontal lobe of the brain. This includes newer medications and various surgical procedures, which can be helpful if medicine alone doesn't control the seizures.

Medications:

Currently available anti-seizure medications appear to be equally effective in controlling frontal lobe seizures. However, not everyone becomes seizure-free using medication alone. It's common to need to try different types of medications, or even a combination of drugs, to find what works best. Researchers are constantly searching for even more effective medications.

Surgery:

If medication doesn't control seizures, surgery might be an option. The goal before surgery is to pinpoint the exact area of the brain where the seizures originate. Doctors use various imaging techniques to locate this area. These include:

• SPECT (single-photon emission computed tomography): This creates images of brain activity.
• SISCOM (subtraction ictal SPECT coregistered to MRI): This combines SPECT with MRI to get a more detailed picture.
• Brain Mapping: Electrodes are placed in the brain to stimulate different areas. This helps determine which areas are important for function, so doctors can avoid damaging crucial parts of the brain during surgery. Functional MRI (fMRI) is particularly useful for mapping areas related to language.

After frontal lobe seizure surgery, patients often still need anti-seizure medication, but sometimes the dosage can be reduced.

Surgical procedures for epilepsy might include:

• Removing the Focal Point: If the seizures always begin in a specific part of the brain, surgeons can remove that small area of brain tissue. This may reduce or even eliminate seizures.
• Isolating the Focal Point: If the seizure-causing area is too important to remove, surgeons may create cuts to isolate it. This prevents the seizures from spreading to other parts of the brain.
• Vagus Nerve Stimulation: A device similar to a pacemaker is implanted to stimulate the vagus nerve. This often reduces the number of seizures.
• Responsive Neurostimulation: This newer technology involves an implanted device that only activates when a seizure starts, stopping the seizure.
• Deep Brain Stimulation (DBS): An electrode is implanted deep in the brain and connected to a stimulator device under the skin. The device sends signals to the electrode to stop seizure activity.

Important Note: It's crucial to discuss all treatment options with a doctor to determine the best approach for individual needs. Surgery is often a last resort, and various factors, including the individual's overall health and the specifics of their seizures, are considered.

Epilepsy can be frustrating for some people. Sometimes, seizures, especially those affecting the frontal lobe of the brain, can cause unusual behaviors like shouting or unusual movements. This can be very upsetting for the person experiencing the seizure and their family.

For families facing this, support groups can be a valuable resource. They provide information about the condition, practical tips, and importantly, emotional support. Support groups can also help children with epilepsy. It's a place where parents can connect with others going through similar experiences, share advice, and feel less alone.

Talking to a counselor can also be helpful. Counseling can provide strategies for managing stress and anxiety related to the seizures and the condition.

Adults with epilepsy can find support in both in-person and online groups. These groups offer a sense of community and understanding, helping them cope with the challenges of living with epilepsy.
