El 99 % de pacientes epilépticos no saben que hay cura” – ELHERALDO.CO

A significant gap in medical communication is leaving many individuals with drug-resistant epilepsy unaware of surgical options that can lead to long-term seizure freedom. Reports highlighting the perspectives of neurology specialists, including Dr. Nadin Abdala, suggest that a vast majority of patients suffering from refractory epilepsy are not informed that surgical intervention may be a viable path to ending their seizures.

While epilepsy is often managed with anti-seizure medications, these treatments are not effective for everyone. For a substantial portion of the patient population, medications fail to provide adequate control, a condition known as drug-resistant or refractory epilepsy. In these cases, the focus of treatment often shifts toward surgical evaluation to identify a specific seizure focus in the brain that can be safely removed or deactivated.

The Awareness Gap in Epilepsy Treatment

The disparity between available surgical treatments and patient awareness is a central concern for neurologists. According to reporting by El Heraldo, the lack of information regarding these options means that many patients continue to endure debilitating seizures and the side effects of multiple medications without knowing that a more definitive solution might exist.

Dr. Nadin Abdala has emphasized that the lack of awareness is a systemic issue. Many patients are treated by general practitioners or neurologists who may not specialize in epilepsy surgery, leading to a failure in referring candidates to specialized epilepsy centers where surgical evaluations take place.

The American Academy of Neurology provides frameworks for the management of epilepsy, emphasizing that for patients who do not respond to two appropriately chosen and tolerated anti-seizure medications, the probability of achieving seizure freedom with further medication is low. At this juncture, the guidelines suggest a referral to an epileptologist for a surgical evaluation.

Understanding Surgical Options for Seizure Freedom

Surgery for epilepsy is not a universal solution, but for those who are eligible, it can be transformative. The primary goal of epilepsy surgery is to remove the area of the brain where seizures originate—the epileptogenic zone—without damaging critical functions such as speech, movement, or memory.

Common surgical approaches include:

• Resective Surgery: The removal of a small, well-defined area of brain tissue, such as in temporal lobe epilepsy, which has some of the highest success rates for seizure freedom.
• Laser Interstitial Thermal Therapy (LITT): A minimally invasive procedure that uses a laser to destroy the seizure-causing tissue, resulting in shorter recovery times.
• Neuromodulation: For patients who are not candidates for resection, devices such as Vagus Nerve Stimulation (VNS) or Responsive Neurostimulation (RNS) can be implanted to reduce seizure frequency and severity.

The process of determining candidacy is rigorous. It typically involves a comprehensive evaluation including high-resolution MRI scans, prolonged video-EEG monitoring and neuropsychological testing to map the brain’s functions and pinpoint the exact origin of the electrical storms.

The Importance of Specialized Care

The transition from medication management to surgical consideration requires a multidisciplinary team. This team usually consists of an epileptologist, a neurosurgeon, a neuropsychologist, and specialized nursing staff.

The American Academy of Neurology advocates for a standardized approach to treating refractory epilepsy to ensure that patients are not left in a cycle of ineffective medication trials. By identifying drug-resistant epilepsy earlier, patients can access surgical evaluations sooner, potentially reducing the long-term cognitive and physical tolls of uncontrolled seizures.

Medical experts stress that while surgery is often referred to in patient-facing contexts as a cure, in clinical terms, This proves described as achieving seizure freedom. This distinction is important because while the seizures may stop, the underlying cause of the epilepsy may remain, and some patients may still require low-dose medication to maintain stability.

Challenges to Access and Information

Beyond the lack of awareness, access to specialized epilepsy centers remains a barrier for many. These centers are often located in major urban hubs or academic hospitals, making it difficult for patients in rural or underserved areas to receive the necessary evaluations.

The goal for the neurological community is to bridge the gap between the existence of these life-altering procedures and the patients who could benefit from them. Increasing the prevalence of surgical referrals and educating patients on the possibility of seizure freedom is considered a priority for improving the public health outcomes of those living with epilepsy.
