Epilepsy Surgery in Dubai: All You Need To Know

Epilepsy is a challenging brain condition that can affect how people live, especially when drugs fail to control seizures. Many individuals see epilepsy surgery as a real chance for seizure control. In the UAE, patients now have access to skilled neurosurgeons like Dr Arun Rajeswaran, who offer advanced treatment options. These include functional neurosurgery and modern neuromodulation therapy, such as DBS for epilepsy and vagus nerve stimulation Dubai. 

What Is Epilepsy Surgery? 

Epilepsy surgery involves specific brain operations aimed at either removing or interrupting the part of the brain that causes seizures. It can also use implanted devices to adjust irregular brain activity. Doctors usually suggest surgery when drugresistant epilepsy continues even after trying at least two effective seizure medications. 

Major types of procedures for epilepsy include: 

• Doctors perform temporal lobe surgery to take out the seizure focus located in the temporal lobe. 

• They may also do seizure control surgery, like removing lesions or specific areas of the cortex causing seizures. 

• Functional neurosurgery involves neuromodulation therapy such as deep brain stimulation (DBS) for epilepsy, responsive neurostimulation, or treatments delivered through vagus nerve stimulation Dubai. 

When Is Epilepsy Surgery Suggested? 

Not everyone with epilepsy needs surgery. Doctors often suggest it in certain cases. 

• People often struggle with seizures because they disrupt work, school, or social activities. These episodes can be frequent and life-altering. 

• At least two antiseizure drugs have not worked well enough to provide proper seizure control. 

• Scans or monitoring highlight a clear epileptic focus in the brain that can be treated with surgery. 

• Surgery carries fewer risks when compared to the long-term dangers of persistent seizures, such as injuries, memory issues, or even sudden unexpected death in epilepsy (SUDEP). 

An expert team, which includes a neurosurgeon like Dr Arun Rajeswaran, along with a neurologist-epileptologist and a neuropsychologist assesses each case to decide if epilepsy surgery in Dubai could be the right solution. 

Temporal Lobe Epilepsy and Surgery for Temporal Lobe Issues 

Temporal lobe epilepsy happens to be the most frequent type of focal epilepsy. It starts in the inner areas of the temporal lobe, like the hippocampus or amygdala. Key signs include: 

• Auras, which might feel like déjà vu, a weird sensation in the stomach, or sudden fear. 

• Episodes of staring or small repetitive movements, like lip-smacking or fumbling. 

• Regular spikes called interictal epileptiform discharges are found in the temporal region when using EEG. 

Doctors often perform temporal lobe surgery to address this condition. 

• Surgeons perform anterior temporal lobectomy or selective amygdalohippocampectomy to take out the area causing epilepsy. 

• They use tools like high-resolution MRI, FDG-PET, and sometimes intracranial EEG to pinpoint the exact spot triggering seizures. 

• During the procedure, teams actively monitor brain activity to protect language and memory abilities when working near the temporal lobe in the dominant hemisphere. 

DBS for Epilepsy 

Deep brain stimulation (DBS) helps treat epilepsy using implanted electrodes. These electrodes send electrical pulses to deep areas of the brain tied to seizure activity. 

How DBS for epilepsy works: 

• Doctors place electrodes in parts like the centromedian thalamic nucleus or other areas connected to epileptic network connectivity. 

• A small device under the skin in the chest acts like a pacemaker, sending pulses that adjust abnormal brain rhythms. 

• This is known as neuromodulation therapy. It can lower both how often and how severe seizures are over time, even when the seizure’s origin cannot be removed. 

Unlike resective surgery, doctors can reverse and adjust DBS electrode placement. This feature makes it a good option to treat patients who have widespread or multiple epileptic networks. 

Vagus Nerve Stimulation Dubai  

Another technique seen in epilepsy surgery UAE programs is vagus nerve stimulation (VNS). It is a type of neuromodulation approach. Here’s how it works: 

• A small device is implanted in the chest, sending consistent electrical signals to the left vagus nerve. 

• The stimulation changes how the brain functions through the vagus nucleus and its connected areas, which can help stop seizures from spreading. 

Here are some advantages of using vagus nerve stimulation Dubaibased treatments: 

• People can consider it when resective surgery isn’t an option, like in temporal lobe epilepsy that affects both sides or has multiple focal points. 

• It may help lower seizure rates by around 30–50% for many, and some could see lasting benefits over time. 

• Doctors pair it with medications since it doesn’t work as a complete cure on its own. 

Other neuromodulation methods include responsive neurostimulation (RNS). This system uses implanted electrodes in the brain to sense seizures starting and stop them. 

Functional Neurosurgery  

Functional neurosurgery treats brain disorders by adjusting or altering specific brain circuits. In cases of epilepsy, this involves techniques like resective surgery, DBS, and other forms of neuromodulation therapy. 

Seizure focus localization: 

• Doctors use high-resolution MRI scans to find hippocampal sclerosis, cortical dysplasia, or other structural problems. 

• EEG and video-EEG monitoring can record seizure events and detect interictal epileptiform discharges. 

• FDG-PET scans, and sometimes SPECT, help locate areas with abnormal metabolism in the brain. 

• In tricky or uncertain cases, invasive tools like depth electrodes or devices for responsive neurostimulation are used to study epileptic network connectivity. 

How Epilepsy Surgery Works in the UAE 

Epilepsy care in the UAE is becoming more advanced and now often matches the standards seen at Level 4 epilepsy centres. Patients can access: 

• Cutting-edge brain imaging and pinpointing seizure origins. 

• Neurosurgical procedures like placing DBS electrodes, stimulating the vagus nerve in Dubai, and resective surgeries. 

• Adjusting medicines, ensuring proper recovery, and giving ongoing care to improve seizure management. 

People thinking about epilepsy surgery UAE or Dubai should consult a skilled neurosurgeon. Dr Arun Rajeswaran, with more than 13 years of expertise in handling complex brain and spine surgeries, provides tailored care focused on patients who experience drug-resistant epilepsy.
