Epilepsy is a non-communicable brain illness that affects approximately 50 million individuals globally. Recurrent seizures are brief episodes of involuntary movement involving a section of the body (partial) or the whole body (generalized).
Epileptic episodes are occasionally accompanied by loss of awareness and control of bowel or bladder function. Excessive electrical discharges in a set of brain cells cause seizure episodes.
Such discharges can occur in many areas of the brain. Seizures can range from minor attention lapses or muscle jerks to severe and lengthy convulsions. Seizures can occur at any time of year, ranging from once a year to multiple times a day.
Dr. Gurneet Singh Sawhney is committed to offering excellent epilepsy treatment in Mumbai to patients suffering from seizures. He is one of the best neurosurgeon in Mumbai. Moreover, he performs safe, advanced, and result-oriented epilepsy surgery in Mumbai. Hence, patients consider him as one of the top epilepsy surgeon in Mumbai.
Now, let’s know,
Symptoms of Epilepsy
During epilepsy, a person exhibits abnormal behaviour, symptoms, and sensations, including loss of consciousness. Epilepsy has only a few symptoms.
Patients may experience the following symptoms:
- Fainting or exhaustion throughout the body.
- Muscle contractions or spasms that are rhythmic.
- Forgetfulness, anxiety, depression, or staring spells are also prevalent.
Causes of Epilepsy
Epilepsy is not spreadable. Although various underlying conditions can cause epilepsy, the aetiology of the disease is still unknown in around half of all cases worldwide.
The following are the several types of epilepsy causes:
- Immunological and unknown
Epilepsy also occurs in the following conditions:
- Brain damage from prenatal or perinatal causes such as low birth weight, loss of oxygen, or trauma during birth)
- Genetic conditions or congenital abnormalities with associated brain malformations
- Severe head injury
- Stroke that reduces the amount of oxygen to the brain
- Brain infection such as meningitis, encephalitis, or neurocysticercosis
- Specific genetic syndromes
- Brain tumor
Why is Epilepsy Surgery Performed?
Dr. Gurneet Sawhney, an experienced epilepsy surgeon in Mumbai, may perform epilepsy surgery to:
- Stop the seizures or make them less severe
- Reduce the number and frequency of seizures
- Control seizures when medications fail
- Treat severe side effects of epilepsy medicines
- Prevent seizures that spreads to other areas of the brain
- Treat seizures that occur on account of scar tissue, brain tumor, birth defect, or arteriovenous malformation (AVM)
Types of Epilepsy Surgery
1. Curative Epilepsy Surgery
Curative epilepsy surgeries are performed to remove the seizure focus area without causing damage to the brain or loss of brain function. Curative epilepsy procedures include lobectomy, cortical excision, and hemispherectomy that focus on removal of the area of the brain that causes seizures.
Dr. Gurneet Sawhney, one of the top neurosurgeon in India, may suggest curative procedures only if the diagnostic tests pinpoint the exact origin of the seizure in the brain.
2. Temporal lobectomy
Neurosurgeons perform this surgery on patients suffering from temporal lobe epilepsy. There is a nearly 70% to 80% reduction in the intensity of the seizure or complete control. The patient’s memory and language can be affected if the surgery is performed on the dominant hemisphere.
3. Cortical excision
This surgery focuses on removing the outer layer of the brain at the focal area of the seizure. The cortical excision surgery has promising results with significant improvement in seizure control in nearly 50% of the patients.
The neurosurgeon will remove the outer layer and the anterior temporal lobe in one section of the brain. Surgeons perform hemispherectomy on children in most cases. It is performed on patients who suffer from intractable seizures and are weak on one side of the body.
These patients usually have a damaged hemisphere in the brain. Post hemispherectomy, the patients show remarkable improvement in attention span, behaviour, and cognitive functioning.
5. Palliative Epilepsy Surgery
Palliative epilepsy procedures focus on reducing the frequency of seizures and/or their severity. The patients have to undergo in-depth testing to locate the exact source of the seizure and the impact of its removal.
Palliative epilepsy procedures are critical procedures as they could affect the quality of life, especially mobility and speech. Palliative procedures include corpus callosotomy, multiple subpial transections, vagus nerve stimulation (VNS), and deep brain stimulation (DBS).
6. Deep brain stimulation (DBS)
During the DBS procedure, the surgeon places a pair of electrodes in the brain. The generator that controls it is implanted in the chest. The frequency and its levels are customized as per the patient while the stimulation remains continuous.
7. Corpus callosotomy
This procedure is a preventive surgery that focuses on preventing the spread of generalized seizures from their original location by disconnecting a section of nerve fibres across the corpus callosum. In the first surgery, the front area of the corpus callosum is sectioned. If the patient does not improve, then the rear area of the corpus callosum is treated in the same manner.
There have been instances of the issue in left-right motor coordination, mutism, and apathy in patients who have undergone total corpus callosotomy. This procedure is a curative and preventive procedure done to prevent the spread or the intensity of seizures.
8. Multiple subpial transections
This procedure involves the creation of small incisions in the brain, especially in the seizure focus area, so that they interfere with the spread of the seizure. This procedure is done in combination with lobectomy or alone. Surgeons perform multiple subpial transections in the seizure focus area in the brain's vital area, which cannot be removed.
9. Vagus Nerve Stimulation (VNS)
In this procedure, the neurosurgeon implants a device that performs functions similar to a heart pacemaker. This device produces electric signals to prevent seizures. The patient can switch on the device indicating the onset of a seizure, and electric signals will be sent to the brain through the vagus nerve.
Neurosurgeons perform VNS on patients who cannot undergo brain surgery. It is not a cure for epilepsy and is not successful in all patients. It can reduce the seizure frequency to about 30%.
The patient could suffer from mild hoarseness in the voice and tingling sensation in the neck in the event of stimulation.
