Epilepsy Surgery

What this procedure is

Epilepsy surgery is a medical procedure used to treat seizures. It involves a surgeon working on the specific area of the brain where seizures begin. The main goal of the procedure is to stop seizures or make them happen much less often.

There are different types of surgery depending on the patient's needs. Some procedures involve removing a small piece of brain tissue where seizures start, which is called a resection. Other types involve "disconnecting" the nerve pathways that allow seizures to spread through the brain. Your clinician may also discuss neuromodulation, which uses a small device to send electrical pulses that help control brain activity.

Before any surgery, doctors perform detailed tests to find the exact spot in the brain causing the trouble. This helps ensure the procedure is as safe as possible and does not affect important functions like speech or movement.

What it treats or fixes

This surgery is primarily used for people with drug-resistant epilepsy. This means that at least two different anti-seizure medications have been tried but were not able to stop the seizures. For many people in this situation, surgery may offer a better chance at seizure control than trying more medications.

The procedure is most effective for focal epilepsy. This is a type of epilepsy where seizures start in one specific, identifiable part of the brain. If that spot can be safely reached without harming vital brain functions, surgery may be an option to help "fix" the source of the electrical storms that cause seizures.

The goals of the procedure include:

• Reducing the number or severity of seizures.
• Improving quality of life, such as the ability to drive or work.
• Lowering the risk of injuries or health complications caused by frequent seizures.
• Potentially reducing the side effects caused by high doses of seizure medications.

How common it is & where it's done

While many people manage epilepsy with medicine, about one-third of people find that drugs do not work well enough. For these individuals, surgery is a standard and well-studied treatment option that has been used for decades. It is performed on both children and adults.

These procedures are typically done at specialized hospitals known as Comprehensive Epilepsy Centers. These centers have teams of experts, including neurologists (doctors who treat the brain), neurosurgeons (surgeons who operate on the brain), and specialized nurses who work together to plan the care.

Your clinician may refer you to one of these centers for a surgical evaluation. This is a series of tests used to determine if surgery is the right path for your specific type of epilepsy. These evaluations are common for patients whose seizures remain uncontrolled after trying initial treatments.

Recovery: What to Expect

After surgery, most people stay in the hospital for 1 to 3 days. During this time, your care team will monitor your healing and manage any discomfort. It is common to feel tired or have a mild headache for the first few weeks. Your clinician may suggest a gradual return to your normal routine, which often takes about 4 to 6 weeks.

While you recover at home, it is important to continue taking your anti-seizure medications exactly as prescribed. Your clinician will decide if or when these medications can be changed in the future. You should contact your care team if you notice any of the following:

• A fever or chills.
• Redness, swelling, or fluid leaking from the incision (the area where the surgery was performed).
• A sudden change in your mood or a new, severe headache.

Risks & Possible Complications

Every surgery carries some risks, such as infection, bleeding, or a reaction to anesthesia (the medicine that puts you to sleep during the procedure). Because epilepsy surgery involves the brain, there is also a small risk of changes in your memory, speech, or vision. These changes depend on which part of the brain is being treated.

To keep you safe, your surgical team uses advanced brain mapping to identify and protect the areas that control your movement and senses. Many side effects that do occur are temporary and often improve as the brain heals and you participate in follow-up care.

Outcomes & Long-Term Results

The primary goal of surgery is to stop seizures or significantly reduce how often they happen. For many people, this leads to a better quality of life, including more independence and the potential to return to activities like driving or working. While many patients see a major improvement, some may still need to take medication to keep seizures under control.

Long-term success is most common when the area causing the seizures is small and clearly defined. Your clinician may perform follow-up tests, such as an EEG (a test that records brain wave patterns), to monitor your progress over the months and years following the procedure.

Emotional Support & Reassurance

Choosing to have surgery is a big decision, and it is natural to feel a mix of hope and nervousness. You are not alone in this process. Many patients find it helpful to speak with a counselor or join a support group to share their experiences with others who have had similar procedures.

Focusing on the potential for fewer seizures and a safer daily life can help you stay positive. Your healthcare team is dedicated to supporting your physical and emotional well-being throughout your recovery and beyond.

Why doctors recommend it

Doctors usually suggest epilepsy surgery when anti-seizure medications do not provide enough control. This is often called drug-resistant or refractory epilepsy. If a person has tried two or more different medications at the right doses and still has seizures, the chance of a third medication working is often very low. In these cases, your clinician may suggest surgery as a more effective path forward.

Surgery is most commonly recommended for people with focal epilepsy. This means the seizures start in one specific, identifiable area of the brain. Before recommending the procedure, your medical team will perform tests to ensure that the area causing seizures can be safely treated without affecting vital functions like your speech, movement, or memory.

Urgent vs planned treatment

Epilepsy surgery is almost always a planned, or elective, procedure. It is not typically performed as an emergency treatment. Because the brain is very complex, the process leading up to surgery is very thorough and can take several months to complete.

During this planning phase, patients undergo a series of evaluations. These may include brain scans (MRI), video monitoring of brain waves (EEG), and memory tests. This careful preparation allows the surgical team to map the brain precisely. Because it is a planned process, you and your family have time to ask questions and feel comfortable with the treatment plan before moving forward.

Goals of treatment

The primary goal of epilepsy surgery is to stop seizures entirely or significantly reduce how often they happen. When seizures are better controlled, many people find they have a much better quality of life and more independence in their daily activities.

Other important goals of treatment include:

• Reducing medication: While some people still need medicine after surgery, many are able to lower their dosage, which can reduce side effects like fatigue or mood changes.
• Improving safety: Fewer seizures mean a lower risk of seizure-related injuries or other health complications.
• Supporting development: In children, stopping seizures early can help the brain develop more normally and improve learning and social growth.
• Better mental health: Reducing the frequency of seizures often helps lower the stress and anxiety that can come with living with epilepsy.

Who may benefit

Surgery is often considered for people with drug-resistant epilepsy. This means that at least two different anti-seizure medications have not been able to control the seizures. Your clinician may suggest surgery if your seizures start in one specific area of the brain, which is called a focal point. When seizures are limited to one spot, doctors can sometimes safely treat that area to stop or reduce the number of seizures.

This option is also common for people whose seizures are frequent or severe enough to interfere with daily life, safety, or work. For children, surgery might be considered early on to help the brain develop more normally and improve their long-term quality of life.

When it may not be the right option

Surgery may not be the best choice if your seizures are well-controlled by medication. It is also usually not recommended if your seizures come from many different parts of the brain rather than one single spot. In these cases, removing one area might not stop the seizures from happening elsewhere.

Your care team will also look at where the seizures start. If the seizures come from a part of the brain that controls vital functions—like speech, movement, or vision—surgery might be too risky. Additionally, if a person has other serious health conditions that make any surgery unsafe, your clinician may look into other treatments like specialized diets or nerve stimulation devices.

Questions to ask your care team

Deciding on surgery is a big step. It is helpful to bring a list of questions to your next appointment to help you and your family make an informed choice. You might consider asking:

• What type of epilepsy surgery do you recommend for me?
• Where exactly in my brain do the seizures start?
• What are the chances that I will be seizure-free after the procedure?
• Will I still need to take anti-seizure medications after surgery?
• How long is the typical recovery time before I can return to work or school?
• What are the most common risks for this specific procedure?

In the procedure room

When you arrive in the operating room, you will be cared for by a specialized team. This group usually includes your neurosurgeon (a doctor who operates on the brain), an anesthesiologist, and several nurses. The room is filled with advanced technology designed to monitor your health and guide the surgeon with precision.

You will be placed in a comfortable position on the surgical table. The team will set up various monitors to track your heart rate, blood pressure, and oxygen levels throughout the entire process. This ensures you stay safe and stable while the doctors work.

High-level steps

The procedure begins with the surgical team clipping a small amount of hair in the area where the surgery will happen. The surgeon then makes an opening in the skull, a step called a craniotomy. This allows them to reach the specific part of the brain that needs treatment.

Using detailed maps of your brain created during your earlier tests, the surgeon will either remove the small area where seizures start or interrupt the nerve pathways that allow seizures to spread. Once the work is complete, the piece of bone is carefully put back in place and secured. The skin is then closed with stitches or staples, and a sterile bandage is applied to the area.

Anesthesia and pain control

Most epilepsy surgeries are performed under general anesthesia. This means you will be in a deep sleep and will not feel any pain or have any memory of the procedure. Your anesthesiologist will stay by your side the entire time to manage your comfort and safety.

In some specific cases, your clinician may suggest an "awake" surgery. During this version, you are given medicine to keep you relaxed and pain-free, but you are woken up for a short time to speak or move. This helps the surgeon identify and protect important areas of the brain, like those used for speech. Local numbing medicine is also used on the scalp to ensure you remain comfortable as you wake up after the procedure.

Monitoring and safety steps

Your safety is the main focus during the surgery. The team often uses intraoperative EEG, which involves placing small sensors directly on the brain to monitor electrical activity in real-time. This helps the surgeon confirm they are targeting the correct area.

The surgical team also uses "brain mapping" or navigation systems, which act like a GPS for the brain. These tools help the surgeon avoid areas responsible for your movement, senses, and language. Constant monitoring of your vital signs ensures that your body is responding well to the procedure at every step.

Immediately after the procedure

After the surgery is finished, you will be moved to a recovery room or an intensive care unit (ICU) for close observation. As the anesthesia wears off, it is normal to feel very sleepy, groggy, or even a bit confused for a short time. You may also have a mild headache or some soreness around the incision site.

You will have a large bandage, sometimes called a head wrap, to keep the area clean and protected. Your care team will check your strength, vision, and speech frequently. They will also provide medicine to help with any discomfort or nausea you might feel as you wake up.

Typical procedure length

Epilepsy surgery is a very careful and detailed process. While the exact time depends on the type of surgery being performed, the procedure typically takes several hours. Most surgeries last between 3 and 7 hours.

Your surgical team will keep your family or loved ones updated during the procedure. Because the brain is so complex, the surgeons take their time to ensure every step is completed with the highest level of safety and precision.

Common approaches (open vs minimally invasive)

Your surgical team will recommend a procedure based on where your seizures start and how easy it is to reach that area safely. The goal is always to stop or reduce seizures while protecting your ability to speak, move, and think.

• Open surgery: This is the traditional method. The surgeon makes an opening in the skull, known as a craniotomy, to view the brain directly. This allows them to remove the specific area of tissue causing the seizures. It is often used for procedures like a lobectomy (removing a lobe of the brain) or a lesionectomy (removing a tumor or scar).
• Minimally invasive surgery: These newer techniques use very small openings. For example, laser interstitial thermal therapy (LITT) uses a laser probe guided by MRI to destroy the seizure-causing tissue with heat. Because the opening is smaller, recovery time is often shorter than with open surgery.

Minimally invasive options are not right for everyone. They are typically chosen when the source of the seizure is small, deep inside the brain, or hard to reach with open surgery.

Partial vs total

Surgeries are also categorized by how much tissue is removed or disconnected. Most epilepsy surgeries are focal, meaning they target a specific spot, but some procedures involve larger areas to stop seizures from spreading.

• Partial (Focal) Resection: This is the most common type of epilepsy surgery. The surgeon removes a small, defined section of the brain where seizures begin, such as the temporal lobe. The rest of the brain is left untouched.
• Total or Extensive Disconnection: In severe cases, especially in children, a larger area may need to be treated. A hemispherectomy involves removing or disconnecting one half (hemisphere) of the brain. Another procedure, a corpus callosotomy, cuts the band of nerve fibers connecting the two halves of the brain. This does not remove brain tissue but stops seizure signals from traveling from one side to the other.

These extensive procedures are generally reserved for patients who have severe seizures affecting a large portion of the brain and who have not improved with other treatments.

Revision or repeat procedures

In some cases, a first surgery may not fully stop the seizures. If this happens, your doctor may evaluate you to see if a second, or revision, surgery could help. This might be considered if tests show that a small piece of the tissue causing the seizures remains.

Revision procedures can be more complex than the first surgery because of scar tissue. Your care team will repeat tests, such as an MRI or EEG, to ensure that a second operation is a safe and practical option for your specific situation.

Tests and imaging that may be done

Before surgery is scheduled, your care team must identify the exact area of the brain where seizures begin. This process is often called a pre-surgical evaluation. It helps the team plan a safe procedure that is tailored to your specific needs.

• Video EEG (Electroencephalogram): You may stay in the hospital for several days while a video camera and sensors on your scalp record your seizures. This helps confirm where the seizures start.
• MRI (Magnetic Resonance Imaging): This scan uses magnets to create detailed pictures of the brain’s structure to look for any abnormalities.
• PET or SPECT scans: These imaging tests look at blood flow and brain metabolism (activity) to help locate the seizure focus.
• Neuropsychological testing: These are tasks that check memory, language, and thinking skills. They help doctors predict how surgery might affect your brain function.

Medication adjustments

Managing your medications correctly is a key part of safety. Your doctor will give you a specific plan for your anti-seizure medicines and any other prescriptions you take.

• Follow instructions exactly: Only stop or change your medicines if your clinician instructs you to do so. Stopping suddenly on your own can be dangerous.
• During testing: If you are having a monitoring session (Video EEG) before surgery, your doctor may lower your medication dose temporarily to allow seizures to happen so they can be recorded. This is done under close medical supervision.
• Other medications: Tell your surgical team about all vitamins, supplements, and over-the-counter drugs you use. You may need to stop taking blood thinners or certain supplements days or weeks before the procedure to reduce the risk of bleeding.

Day-before and day-of instructions

As your surgery date approaches, the hospital will provide a checklist to help you get ready. Following these steps helps prevent infection and complications with anesthesia.

• Hygiene: You may be asked to wash your hair with a special soap or shampoo the night before or the morning of surgery. Do not use hairsprays, gels, or oils after washing, as these can interfere with the equipment.
• Fasting: You will likely need to stop eating and drinking for a set time, usually after midnight the night before surgery. This keeps your stomach empty for anesthesia.
• Clothing and items: Wear loose, comfortable clothing that is easy to change out of. Leave jewelry and valuables at home.
• Arrival: Plan to arrive at the hospital or surgery center early to complete paperwork and meet with the anesthesia team.

General surgical risks

Like any major operation, epilepsy surgery carries some general risks. These are not specific to the brain but can happen with many types of surgery. Your surgical team takes standard precautions to lower the chance of these issues occurring.

• Infection: This can happen at the site of the incision or deeper inside the body.
• Bleeding: Doctors monitor you closely to manage bleeding during and after the procedure.
• Anesthesia reactions: Some people may have an allergic reaction or other side effects from the medication used to put them to sleep.

Procedure-specific complications

Because this surgery involves the brain, there are specific risks related to brain function. The likelihood of these complications depends on which part of your brain is being treated. Extensive testing is done before surgery to identify and avoid critical areas.

• Memory and language: You may experience changes in your memory or ability to find words. These issues are often temporary but can sometimes be permanent.
• Vision changes: Some procedures may affect your visual fields, such as losing part of your peripheral (side) vision.
• Mood changes: It is common to feel depression or anxiety after surgery as the brain heals and adjusts.
• Physical weakness: You might notice weakness or numbness on one side of your body.

More serious complications, such as a stroke, are rare. Your doctor will discuss the specific risks relevant to your case based on your test results.

How complications are treated

Most complications can be managed with medication, therapy, or time. Your care team will monitor you closely in the hospital to catch and treat any issues early.

• Medication: Doctors may prescribe antibiotics for infections or steroids to reduce brain swelling. Pain relievers are used to manage headaches.
• Rehabilitation: If you experience weakness, speech problems, or vision changes, therapies such as physical, occupational, or speech therapy can help you recover function.
• Counseling: Psychological support and medication can help manage mood changes like depression or anxiety during your recovery.

Many side effects improve over time as the swelling goes down and the brain heals. Regular follow-up appointments allow your clinician to track your progress and adjust your care plan.

Pain control medicines

Keeping you comfortable after surgery is a top priority for your care team. Your clinician may use a combination of different medicines to manage pain. This often includes common options like acetaminophen or prescription-strength medications if needed. Using a mix of medicines can often help provide better relief with fewer side effects.

Your medical team will tailor the plan based on your health history and how you feel during recovery. It is important to tell your doctors about any past reactions to pain medicine or if you have a history of sensitive stomach. They will monitor you closely to help manage any side effects, such as sleepiness or nausea, while ensuring you stay comfortable.

Antibiotics

Antibiotics are medicines used to prevent or treat infections caused by bacteria. To help keep the surgical site healthy, your clinician may give you antibiotics through an IV (a small tube in your vein) just before the procedure starts and for a short time afterward. This is a standard safety step for most surgical procedures.

Before surgery, be sure to mention any known drug allergies, such as an allergy to penicillin. Your team will choose the safest antibiotic for your specific needs to help ensure a smooth recovery. They will also check for any potential interactions with your current seizure medications.

Blood thinners and clot prevention

Because you will be resting in bed for a while after surgery, your clinician may take steps to prevent blood clots from forming in the legs. This is often called clot prophylaxis. Preventing these clots is important for a safe recovery while your activity is limited.

• Medications: You may receive a low dose of a blood thinner, also called an anticoagulant, to keep your blood flowing smoothly.
• Mechanical methods: Your team might also use compression boots or special stockings that gently squeeze the legs to help circulation.

Your doctors will carefully balance these treatments to prevent clots while making sure your surgical site heals properly. Always tell your clinician if you have a history of bleeding issues or if you have taken blood thinners in the recent past.

Emergency warning signs

Although serious complications are rare, it is important to act quickly if a medical emergency occurs. You or a caregiver should call 911 (or your local emergency number) or go to the emergency room if you experience:

• Trouble breathing or chest pain.
• A seizure that lasts longer than 5 minutes, or seizures that happen back-to-back without recovery in between.
• Sudden, severe confusion or difficulty staying awake.
• Sudden weakness on one side of the body or sudden trouble speaking.

Call your surgeon or clinic if…

Your surgical team will give you specific instructions on when to contact them. generally, you should call your surgeon or clinic if you notice signs of infection or other changes, such as:

• Fever (often defined as higher than 101°F or 38.3°C, or as directed by your doctor).
• Incision issues, such as increased redness, swelling, warmth, or pus leaking from the wound.
• Severe headache that gets worse or does not improve with pain medicine.
• New vision changes, such as double vision or loss of side vision.
• Mood changes, such as feeling deeply sad, depressed, or anxious.

Expected vs concerning symptoms

Recovering from brain surgery takes time, and your body will go through many changes as it heals. Knowing what is typical can help you feel more prepared.

Most people have:

• Headaches: It is common to have a headache for several days after surgery. This usually gets better with rest and medication.
• Swelling and bruising: You may have swelling or bruising on your face or around your eyes. This is a normal reaction to surgery and usually fades on its own.
• Fatigue: You will likely feel very tired and need extra rest for several weeks.

Call if you notice:

• Clear fluid leaking: If clear, watery fluid drips from your incision or nose, it may be a sign of a brain fluid leak.
• Stiff neck: A very stiff neck, especially if you also have a fever, can be a sign of a serious infection.
• Worsening weakness: While some temporary weakness can occur, new or worsening loss of strength should be checked by your clinician.

Non-surgical treatments

Before considering surgery, your clinician may recommend several other treatments. The most common approach is using anti-seizure medications. Many people find that the right drug or combination of drugs can successfully control their seizures. If one medication does not work or causes too many side effects, your doctor might try a different one.

Other non-surgical options include:

• Dietary therapies: Special diets, such as the ketogenic diet or the modified Atkins diet, can sometimes help reduce seizures, especially in children. These diets are high in fats and low in carbohydrates.
• Neuromodulation: These are devices that use mild electrical pulses to help control brain activity. Examples include Vagus Nerve Stimulation (VNS), which uses a small device under the skin of the chest, or Deep Brain Stimulation (DBS). While these involve a procedure to place the device, they do not involve removing brain tissue.

Watchful waiting

In some cases, your medical team may suggest a period of watchful waiting. This means they will closely monitor your condition while continuing with current treatments. This approach allows clinicians to see if your seizures change over time or if a new medication might be effective.

During this time, you might keep a seizure diary to track how often seizures happen and what they feel like. This information helps the team decide if your current plan is working or if it is time to explore other options. Watchful waiting is often used when seizures are infrequent or when the risks of surgery are being carefully weighed against the benefits of waiting for more data.

When surgery becomes the best option

Surgery is usually considered when "drug-resistant epilepsy" is diagnosed. This typically happens after a person has tried two or more different anti-seizure medications at the right doses without success. Research shows that if the first two medications do not work, the chance of a third one providing complete seizure control is often quite low.

Your clinician may recommend surgery if:

• The seizures start in a single, well-defined area of the brain (called a seizure focus).
• The area where seizures start can be safely treated without affecting vital functions like speech, movement, or vision.
• The seizures are frequent enough to interfere with your safety, education, or daily life.

The goal of surgery is to improve your quality of life by stopping or significantly reducing the number of seizures you experience. For many, this path offers the best chance at long-term relief when other treatments have not provided enough help.

Hospital services that commonly perform this surgery

Epilepsy surgery is typically performed at specialized medical facilities known as Comprehensive Epilepsy Centers. These centers are equipped with advanced technology to monitor brain activity and identify the exact location where seizures begin. Because this surgery requires specific expertise, it is rarely done at general community hospitals.

At these centers, a multidisciplinary team (a group of specialists from different fields) works together to plan the procedure. This team usually includes an epileptologist, which is a neurologist who specializes in treating epilepsy. It also includes a neurosurgeon, who is a doctor trained to perform brain surgery. Other experts, such as neuroradiologists and neuropsychologists, help map out brain functions like memory and speech to ensure the surgery is as safe as possible.

Patient resources and support services

Many hospitals provide dedicated support services to help patients and their families through the surgical process. This often includes access to epilepsy coordinators or specialized nurses. These professionals act as a main point of contact to answer questions about testing, scheduling, and what to expect during recovery.

Support services may also include:

• Social Workers: These professionals can help with the logistics of care, such as finding local lodging for family members or navigating insurance and disability paperwork.
• Support Groups: Many centers host groups where patients can talk with others who have undergone similar procedures. Sharing experiences can help reduce anxiety and provide practical tips for life after surgery.
• Educational Materials: Hospitals often provide videos, brochures, and classes to explain the different types of surgery and the monitoring process in plain language.

Questions for choosing where to have surgery

Choosing the right facility is an important part of the process. Your clinician may recommend looking for a center that is recognized by national organizations for meeting high standards of care. You may want to use the following checklist when speaking with a surgical team:

• How many epilepsy surgeries does this hospital perform each year?
• Does the center have a dedicated Epilepsy Monitoring Unit (EMU) to study my seizures before surgery?
• Will I have access to a team that includes both neurologists and neurosurgeons who specialize only in epilepsy?
• What kind of emotional and social support is available for me and my family during the hospital stay?
• What are the long-term follow-up procedures to monitor my progress after I go home?

Your clinician may also suggest asking about the specific success rates for the type of surgery they are recommending for your specific condition.

Conditions commonly treated by this procedure

Epilepsy surgery is most often considered for people with drug-resistant epilepsy (also called refractory epilepsy). This means that seizures continue to occur even after a person has tried at least two different types of anti-seizure medications at effective doses.

Clinicians may also recommend surgery for specific conditions, including:

• Focal epilepsy: Seizures that start in one specific area of the brain.
• Temporal lobe epilepsy: The most common type of focal epilepsy treated with surgery.
• Brain lesions: Physical issues like small tumors, scars from old injuries, or abnormal blood vessels that trigger seizures.
• Pediatric syndromes: Certain conditions in children, such as Lennox-Gastaut syndrome or Sturge-Weber syndrome, may be managed with specialized surgical techniques.

Related symptoms people search for

People exploring surgical options often deal with symptoms that affect their independence and safety. These may include frequent seizures that cause a temporary loss of awareness or "staring spells."

Other symptoms and concerns that can be associated with epilepsy include:

• Auras: Warning signs or unusual sensations (like a strange smell or a "rising" feeling in the stomach) that happen right before a seizure.
• Memory and thinking issues: Difficulty with focus or remembering things, which can sometimes be caused by frequent seizure activity.
• Medication side effects: Challenges like extreme fatigue, dizziness, or mood changes caused by high doses of anti-seizure drugs.
• Physical injury: Concerns about falls or other injuries that may happen during a seizure.

If you or a loved one are experiencing these symptoms, it is important to have a thorough evaluation by a clinician to determine the best path forward.

Evidence overview

Epilepsy surgery is a well-established medical treatment, not an experimental procedure. It is widely recognized by medical experts as an effective option for people whose seizures are not controlled by medication alone (often called drug-resistant epilepsy). Research and clinical experience show that for carefully selected candidates, surgery can significantly reduce the frequency of seizures or stop them altogether.

The success of the surgery depends on the specific type of epilepsy and where the seizures start in the brain. While some procedures aim for complete seizure freedom, others are designed to reduce the severity of attacks. Studies indicate that successful surgery can lead to improvements in quality of life, such as the ability to drive, work, and participate more fully in daily activities.

Safety notes and individualized care

Every surgery carries some level of risk. Your care team will weigh these risks against the dangers of ongoing, uncontrolled seizures. General risks associated with any surgical procedure include infection, bleeding, or reactions to anesthesia. Because these procedures involve the brain, there are also specific risks related to brain function.

Depending on the area of the brain being treated, potential side effects may include:

• Changes in memory or language skills
• Visual disturbances
• Changes in mood, such as depression or anxiety
• Temporary or permanent weakness in part of the body

To maximize safety, doctors perform a comprehensive pre-surgical evaluation before recommending an operation. This involves detailed testing—such as video-EEG monitoring and advanced MRI scans—to pinpoint the exact source of the seizures. This process helps the surgical team create a personalized plan intended to target the seizure focus while protecting healthy brain tissue responsible for movement, speech, and vision.
