Epilepsy surgery is a treatment for people with epilepsy whose seizures do not improve with medication. This surgery aims to reduce or eliminate seizures by targeting the part of the brain where they originate. Doctors use special tests and scans to locate the source of the seizures in the brain precisely. Once they identify the spot, they can determine the best approach to treat it. Sometimes, the surgery involves removing the part of the brain that causes seizures. In other cases, doctors may use techniques to reduce the activity in this area or prevent it from sending signals that trigger seizures. Before the surgery, doctors conduct a thorough evaluation of the patient to ensure it's the right option. They also discuss potential risks and benefits with the patient. Afterward, patients may need some time to recover and adjust to their new situation. Overall, the goal is to help people live a more normal life by reducing the frequency and severity of seizures.
Epilepsy is marked by recurrent seizures, which can differ in type and severity:
Generalized seizures involve the entire brain and may result in loss of consciousness, muscle stiffness, and jerking movements.
Focal seizures originate in one area of the brain and can cause unusual sensations, movements, or emotions. They may or may not result in a loss of consciousness.
Additional symptoms can include:
Confusion or disorientation after a seizure.
Unusual behaviors or sensations before a seizure (aura).
Memory loss related to seizure episodes.
Various factors can cause epilepsy:
Genetic factors: Family history or genetic mutations may contribute to the development of this condition.
Brain injury: Trauma, stroke, or infection can lead to epilepsy.
Brain tumors: Growths in the brain can cause seizures.
Developmental disorders: Conditions affecting brain development, such as cortical dysplasia.
Neurological conditions: Conditions like neurodegenerative diseases can be linked to epilepsy.
Seek medical attention if:
Seizures are frequent: If seizures occur despite medication.
Seizures are worsening: Increasing in frequency or severity.
Seizures are uncontrolled: Medication doesn't seem to help.
New symptoms develop: Changes in seizure patterns or the emergence of new symptoms.
To determine if epilepsy surgery is appropriate, doctors use various tests:
Electroencephalogram (EEG): Measures electrical activity in the brain to locate seizure focus.
Magnetic Resonance Imaging (MRI): Provides detailed images of brain structures to identify abnormalities.
Functional MRI (fMRI): Assesses brain activity and helps in planning surgery.
PET scan: Shows how brain tissues use glucose and can identify areas involved in seizures.
Stereoelectroencephalography (SEEG): Involves placing electrodes in the brain to pinpoint seizure origins.
Do's:
Follow pre-surgery instructions: Adhere to guidelines provided by your healthcare team.
Discuss all options: Understand the risks, benefits, and expected outcomes of the surgery.
Prepare for recovery: Arrange for post-surgery care and follow-up appointments.
Engage in rehabilitation: Participate in therapy to aid recovery and adaptation.
Don'ts:
Avoid skipping medications: Continue taking prescribed medications until advised otherwise.
Don't ignore symptoms: Report any new or worsening symptoms to your doctor.
Avoid making rash decisions: Ensure you understand all options and implications before proceeding with surgery.
Don't overlook lifestyle adjustments: Follow recommendations for lifestyle changes that may support recovery and seizure management.
