Once seizures are captured and analyzed, the team will study the intracranial monitoring results to guide the next steps of care. Patients often worry about any potential neurological deficits following surgery, which is largely determined by the extent of the resection: the larger the resection, the more potential for post-surgical complications and/or deficits. The goal is to minimize the resection volume as much as possible while including the entire epileptogenic zone. If the epilepsy focus is deep, the required access to resect this region can be technically and surgically challenging. However, if the area is confined to a specific region, LITT (Laser Interstitial Thermal Therapy) treatment may be a viable option. This technique involves a small incision coupled with the ROSATM robotic arm to deliver carefully monitored pulses of heat to "burn" and obliterate the epileptogenic zone while protecting the surrounding healthy tissues. This minimally invasive approach provides for a faster recovery time and shorter hospital stay.Another recent technological advance is RNS (Responsive Neurostimulation) technology that allows certain patients to become the surgical candidate who was previously deemed, non-surgical candidates. As previously discussed, there may be neurological deficits following surgery, especially if the epileptogenic zone includes eloquent cortex where resection of these regions will cause undesirable functional outcomes. Other patients may have multiple brain areas that are causing seizures, making resection of all these regions a challenge. With the availability of RNS, these patients now have a surgical option that can be curative and not suffer any neurological deficits. Briefly explained, the epileptogenic zones are covered by implanted EEG electrodes and connected to a small EEG detection device implanted in the skull. This device continuously monitors EEG activity and can be programmed to detect EEG seizure activity at which time, it will deliver an electrical impulse to stop the seizure. As the device continues to learn the patient's seizure pattern, the detection becomes more precise over time. In patients where the epileptogenic zone is too broad for surgical resection, other treatment options include VNS (Vagal Nerve Stimulation) where a neurostimulator is implanted in the chest and connected to the vagus nerve in the neck. Another recently approved medical device, DBS (Deep Brain Stimulation), involves placing electrodes in the anterior thalamus (deep part of the brain) and connected to a neurostimulator in the chest. In both devices, electrical stimulation is sent directly to the brain to reduce seizure frequency and severity. Epilepsy is one of the most common neurological problems, and up to 20-40 percent of patients with epilepsy can become refractory to conventional medications. Seizures negatively impact these patient's lives in several aspects from cognitive skills to mental health, employment, relationships, and social interactions. Hence the goal of treatment is to eliminate them and if this is not possible, minimize the seizure burden to afford patients optimal quality of life. Innovative technology has propelled epilepsy treatment into new frontiers, allowing more people to live seizure-free and have a greater degree of control over this debilitating disease.
