Surgery Decision

Epilepsy surgery evaluation reviews the diagnosis, previous medication treatment, EEG or Video EEG findings and brain imaging to understand whether surgery may be an appropriate option. Dr. Abhishek Gohel and Dr. Rutul Shah provide clinical presurgical assessment at both Gujarat Epilepsy & Neuro Clinic and KD Hospital. A multidisciplinary hospital team considers the findings, alternatives, risks and your preferences. Any operation is performed by the KD Hospital surgical team. Evaluation does not mean that surgery will be recommended, and outcomes vary.

Expected Outcomes After Epilepsy Surgery

Outcomes are individual and uncertain. Some selected patients achieve seizure freedom; others have fewer seizures or continued seizures. Expectations depend on epilepsy type, MRI and EEG findings, the proposed procedure and follow-up duration. These are not clinic-specific outcome claims.

If you're considering epilepsy surgery in Ahmedabad, our neurologists can assess whether further pre-surgical evaluation is appropriate; the hospital team considers candidacy and any surgical plan.

Who is a Candidate for Epilepsy Surgery?

Referral for evaluation is different from a decision to operate. The 2022 ILAE expert consensus supports timely referral once drug resistance is established, even when a seizure focus has not yet been identified. Assessment considers:

  • Have drug-resistant epilepsy: Two adequately tried, appropriately chosen and tolerated medication schedules, alone or in combination, have not achieved sustained seizure freedom
  • Seizure type: Focal seizures may suggest a potential target, but other epilepsy types can also warrant specialist evaluation
  • Localization: Testing assesses where seizures start; an unclear focus does not exclude referral
  • Seizure burden: Frequency, severity, injuries and effects on quality of life inform decisions
  • Patient preferences: Willingness to undergo assessment and informed discussion of testing and treatment risks
  • Medication review: Diagnosis, drug choice, tolerability, dose and adherence are checked without delaying referral for repeated additional trials

Specific Conditions That May Benefit from Surgery

  • Temporal lobe epilepsy with hippocampal sclerosis
  • Focal cortical dysplasia (FCD)
  • Cavernous malformations causing seizures
  • Low-grade tumors associated with epilepsy
  • Post-stroke or traumatic epilepsy with clear lesions
  • Tuberous sclerosis complex with dominant tubers

What is the Pre-Surgical Evaluation Process?

The journey toward epilepsy surgery begins with a thorough evaluation to determine if you are a suitable candidate. Tests are selected to answer the questions relevant to your case.

In practical terms, pre-surgical evaluation tries to answer four questions: are the events definitely epileptic, where do they start, is there a structural target, and can that target be treated without unacceptable risk to memory, language, movement or vision?

The work-up usually begins with history, seizure videos, Video EEG and high-resolution epilepsy MRI. PET, ictal SPECT, MEG, functional mapping or neuropsychology are added only when they answer a specific localization or safety question.

1

Initial Consultation & History

Detailed seizure history, medication trials, impact on quality of life, and thorough neurological examination. We review all previous medical records and imaging studies.

2

Video-EEG Monitoring

Long-term video-EEG monitoring to capture and analyze seizure events, localize the seizure focus, and characterize seizure semiology in detail.

3

High-Resolution Brain MRI

Epilepsy-protocol MRI planning and review to look for structural abnormalities, hippocampal sclerosis or subtle lesions. The protocol and scanner arrangements should be confirmed with the imaging facility.

4

Neuropsychological Testing

Complete cognitive assessment to evaluate memory, language, and other brain functions, helping predict surgical outcomes and plan rehabilitation.

5

Functional Brain Imaging

PET or ictal SPECT may add localization information when needed; neither is required for every patient. Test arrangements depend on clinical need and confirmed facility availability.

6

Multidisciplinary Team Review

A multidisciplinary hospital team, with relevant neurology, neurosurgery, radiology and neuropsychology input, considers the findings, alternatives and individual risks before recommending any surgery.

Functional MRI and Cognitive Risk Assessment

The 2017 AAN fMRI guideline supports selected uses of functional MRI for language lateralization and prediction of some language or memory outcomes. Evidence varies by epilepsy type and task; fMRI is not required for every patient and cannot assure preservation of function. Neuropsychological assessment and, where appropriate, other mapping tests inform counselling. Availability should be confirmed with the treating facility.

A Wada-test case report in Dyke-Davidoff-Masson syndrome, co-authored by Dr. Rutul Shah and Dr. Abhishek Gohel, provides research context for presurgical language assessment. It is not evidence of mesial temporal sclerosis surgical outcomes or confirmation of local Wada-test availability. The hospital team decides whether any additional functional testing is appropriate.

Phase 2 Evaluation: Advanced Monitoring

Some patients require additional invasive monitoring to precisely locate the seizure focus before surgery can be recommended:

Stereo-EEG (sEEG)

When non-invasive testing leaves a specific localization question unresolved, the hospital team may consider stereo-EEG. It is not required for everyone and does not assure a subsequent operation. Availability and risks should be confirmed with the treating facility. This technique involves:

  • Precise electrode placement: Multiple depth electrodes are placed directly into brain tissue using stereotactic guidance
  • Detailed brain mapping: Direct recording from deep brain structures and cortical areas not accessible with surface electrodes
  • Seizure localization: Precise identification of seizure onset and spread patterns
  • Functional mapping: Testing of brain functions (language, memory, motor) to avoid critical areas during surgery
  • Safety profile: Depth electrode implantation is invasive and carries risks, including bleeding and infection, requiring individual counselling

When is Stereo-EEG Needed?

  • Multiple possible seizure foci identified on non-invasive testing
  • Seizures appear to originate from deep brain structures
  • Complex seizure patterns requiring detailed mapping
  • Need to evaluate both hemispheres of the brain
  • Previous surgery with recurrent seizures

What Types of Epilepsy Surgery May Be Considered?

These are general educational examples, not a list of procedures confirmed available locally. A hospital team considers the approach, suitability and individual risks after evaluation; availability must be confirmed with the treating facility.

Surgery Type Description Potential Candidates Individual Outcome Considerations
Temporal Lobectomy Removal of part of the temporal lobe, often including the hippocampus Temporal lobe epilepsy with hippocampal sclerosis Seizure freedom may be possible; benefit and memory risks depend on individual findings
Focal Resection Removal of specific brain area where seizures originate Well-defined lesions causing epilepsy Outcome depends on localization and whether treatment can be performed safely
Radiofrequency Ablation (RF) Minimally invasive destruction of seizure focus using radiofrequency heat Small, deep lesions; previous surgery candidates Benefit varies with the target and treatment extent; seizures may persist
Corpus Callosotomy Disconnection of brain hemispheres to prevent seizure spread Generalized epilepsy with drop attacks Aims to reduce disabling drop attacks; seizure freedom is not assured
Hemispherectomy Disconnection or removal of one brain hemisphere Severe epilepsy affecting one hemisphere in children Seizure benefit and neurological consequences require individualized assessment

What Happens During Epilepsy Surgery?

Understanding the surgical process can help ease anxiety for patients and families. The details depend on the chosen procedure and treating hospital:

Before the Operation

The neurosurgical team reviews all pre-surgical evaluation data — video-EEG findings, MRI scans, neuropsychological test results, and the surgical plan. The patient receives a detailed counselling session where the surgical approach, expected outcomes, and specific risks are explained. Written informed consent is obtained.

In the Operating Room

The procedure is performed under general anaesthesia in most cases. For surgeries near critical brain areas that control speech, language, or movement, an awake craniotomy may be used — the patient is kept conscious during specific portions so the team can test brain function in real time.

For an open resection or disconnection, steps may include the following. Not all steps apply to every procedure:

  • Craniotomy: A section of the skull bone is carefully removed to access the brain
  • Neuronavigation: Computer-guided imaging helps the surgeon precisely locate the epileptogenic zone identified during pre-surgical evaluation
  • Electrocorticography (ECoG): Electrodes placed directly on the brain surface record electrical activity to help guide selected procedures
  • Cortical stimulation mapping: Small electrical currents identify areas controlling speech, motor function, and sensation — these areas are carefully preserved
  • Resection or disconnection: The epileptogenic tissue is removed or disconnected based on the surgical plan
  • Intraoperative neuromonitoring: Somatosensory evoked potentials (SSEP) and motor evoked potentials (MEP) may help monitor relevant pathways; monitoring does not eliminate neurological risk
  • Closure: The bone flap is replaced and secured, and the scalp is closed

Procedure duration and admission arrangements depend on the surgical plan and hospital. SEEG implantation and monitoring are separate from any later therapeutic surgery; recorded findings may support surgery, further assessment or non-surgical treatment.

Recovery After Epilepsy Surgery

Recovery is individualized according to the procedure, neurological status and hospital team's advice. The following describes care needs, not a fixed timetable:

Hospital Stay

  • Early monitoring: The level and duration of monitoring depend on the procedure and recovery. The team reviews neurological status, vital signs, seizures and pain, with additional treatment as needed.
  • Ward care: Mobilisation progresses as advised. The surgical team monitors wound healing and adjusts medications.
  • Discharge: Once neurologically stable, patients are discharged with detailed instructions for home care, medication schedules, and follow-up appointments.

Early Home Recovery

Follow the discharge plan for rest, wound care, activity restrictions and warning symptoms. Report new or worsening symptoms rather than assuming they are expected. Restrictions on lifting, exercise and other activities are individualized.

Gradual Return to Activity

Resume daily activities gradually when the treating team advises. Wound review and seizure assessment are scheduled according to recovery, not a universal interval.

Ongoing Rehabilitation

Return to work or school depends on recovery, seizures, cognitive function and activity demands. EEG, MRI or neuropsychological reassessment may be arranged when clinically indicated.

Medication After Surgery

Continue anti-seizure medicines as prescribed after surgery. Whether and when to reduce them depends on seizure outcome, the procedure, investigations and recurrence risk. Any taper requires the treating neurologist's supervision; abrupt discontinuation can trigger seizures.

Follow-Up Schedule

The hospital team provides an individualized schedule for wound review, seizure monitoring, medication management and any further tests. Seek earlier review for concerns identified in the discharge instructions.

Driving

Do not assume surgery or an interval without seizures permits driving. Discuss medical fitness with your treating neurologist and confirm applicable licensing requirements with the licensing authority before considering a return to driving.

Risks and Complications of Epilepsy Surgery

Like any brain surgery, epilepsy surgery carries certain risks. Continued uncontrolled seizures also carry risks, including injury and sudden unexpected death in epilepsy (SUDEP). The balance between seizure-related and surgical risks must be assessed individually; surgery is not necessarily the safer option for every patient.

General Surgical Risks

  • Infection at the surgical site (uncommon with modern sterile techniques)
  • Bleeding (haematoma formation)
  • Adverse reactions to anaesthesia
  • Blood clots (deep vein thrombosis)

Neurological Risks

  • Memory changes: Particularly with temporal lobe surgery. Memory changes can be significant or persistent. Neuropsychological testing and selected functional mapping help assess risk but cannot eliminate it.
  • Speech and language difficulties: May occur if surgery is near language areas. Cortical mapping during surgery helps protect these zones. Difficulties may be temporary or permanent.
  • Visual field deficits: A partial visual field cut (superior quadrantanopia) can occur after temporal lobe surgery. This can affect daily activities and medical fitness for driving.
  • Weakness or numbness: Weakness or sensory changes may be temporary or permanent, depending on the surgical location and complications.
  • Mood changes: Mood or behavioural changes may occur after surgery. Discuss assessment and support needs with the treating team.

The specific risks depend on the type of surgery and the brain region involved. Your epileptologist and neurosurgeon will discuss the individual risk profile specific to your case during the pre-surgical counselling session.

This information is for educational purposes. Individual risk profiles vary — consult your treating neurologist for a personalised assessment.

Life After Epilepsy Surgery — What to Expect

Surgery may improve seizure control and quality of life in selected patients, but outcomes and recovery cannot be predicted with certainty.

Seizure Outcomes

  • Temporal lobe epilepsy surgery: Seizure freedom is possible in selected cases; outcome depends on localization, pathology and the planned procedure
  • Extratemporal epilepsy surgery: Outcomes depend on how well the seizure-generating area is identified and can be treated safely
  • Lesional epilepsy (surgery for tumours, cavernomas, or cortical dysplasia): An MRI lesion can help identify a target, but concordance with seizure and EEG findings and safe treatment remain important

Some patients have fewer or less severe seizures without becoming seizure-free; others continue to have disabling seizures. Follow-up assesses seizure burden, cognition and quality of life rather than assuming benefit.

Returning to Work and Daily Life

Return to work, school and social activities is planned individually according to recovery, seizure control, cognitive needs and occupational risks. Some patients need rehabilitation or ongoing support.

Marriage and Family Planning

Surgery does not assure a safer pregnancy or allow automatic medication reduction. Discuss pregnancy plans with your neurologist and obstetric team in advance so seizure control and medication-related risks can be reviewed. Do not change medicines without advice.

Emotional Well-Being

Changes in seizure burden can affect confidence, independence and emotional well-being. Adjustment may take time; persistent anxiety, depression or behavioural changes deserve assessment. Counselling or support groups may help.

Long-Term Follow-Up

Even after achieving better seizure control, regular follow-up with your epilepsy specialist in Ahmedabad remains important. The review schedule is individualized to monitor late seizure recurrence, medication needs, cognition and well-being.

Frequently Asked Questions About Epilepsy Surgery Evaluation

Persistent seizures after two adequately tried, appropriately chosen and tolerated medication schedules warrant specialist assessment for drug resistance and timely consideration of surgical evaluation. A visible MRI lesion or an already identified focus is not required for referral. Our neurologists assess your situation; a multidisciplinary hospital team considers whether surgery is appropriate. Evaluation does not assure surgery or seizure freedom.
Epilepsy surgery carries risks including infection, bleeding, memory or language changes, visual field loss and other neurological deficits. Effects may be temporary or permanent. Risks and possible benefits depend on the proposed procedure and individual findings. The treating hospital team discusses these alongside non-surgical alternatives before any decision.
Stereo-EEG uses depth electrodes to record brain activity when a specific localization question remains after non-invasive tests. It may be considered for deep or multiple possible seizure origins. It is invasive, with risks including bleeding and infection, and does not assure subsequent surgery. The hospital team assesses need and confirms availability.
There is no fixed duration. Timing depends on the required tests, capturing typical events, facility scheduling and multidisciplinary review. Additional or invasive monitoring may extend assessment. Confirm an individualized plan before arranging travel.
Evaluation can still help clarify diagnosis and improve treatment planning if surgery is not appropriate. Options may include medication optimization, supervised dietary therapy or assessment for neuromodulation, depending on the epilepsy type and confirmed availability. Reassessment may be appropriate if clinical information changes.
Coverage depends on your policy, proposed tests, hospital and insurer authorization. Obtain a case-specific estimate and confirm coverage and any pre-authorization directly with the hospital and insurer before booking. Coverage or cashless treatment must be confirmed with the hospital and insurer.
Neurologist assessment can begin in Ahmedabad. The tests and any hospital-based surgical assessment depend on your needs. Confirm the required services, treating team and procedure availability with the facility, including KD Hospital if proposed. Some patients may need referral elsewhere; evaluation does not assure local surgery.
