The global subdural electrodes market size was valued at USD 32.4 million in 2021. The market is projected to grow from USD 37.4 million in 2022 to USD 66.5 million by 2029, exhibiting a CAGR of 8.6% during the forecast period. The global COVID-19 pandemic has been unprecedented and staggering, with subdural electrodes experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. Based on our analysis, the global market exhibited a decline of 14.1% in 2020 as compared to 2019.
These devices are primarily used for intracranial monitoring carried out in patients experiencing seizures and epileptic episodes in the pre-surgical phase of epilepsy. These procedures are carried out in patients who fail to respond to medications and require surgery. It facilitates locating the lobe of origin of seizures, which will help guide the surgical procedure. Based on seizure location, a particular type of electrode is recommended. For instance, if the focus of a seizure is believed to be in the brain, then a depth electrode is recommended for intracranial monitoring.
An increasing number of epilepsy surgeries, the rising adoption of intracranial monitoring, and the prevalence of epilepsy are anticipated to boost the subdural electrodes market growth during the forecast period. For instance, as per a study published in 2022 by ScienceDirect, 65 million people worldwide are affected by epilepsy, and almost 80.0% are from developing countries. Furthermore, a considerable proportion of patients with epilepsy have Drug-Resistant Epilepsy (DRE), affecting 30-40% of epileptic patients. This prevalence represents higher growth for intracranial monitoring, which signifies a higher demand for these products during the forecast period.
Closure of Specialized Epilepsy Care Centers due to COVID-19 has led to Slower Growth of the Global Market
The COVID-19 pandemic has negatively influenced market growth due to a multitude of factors. Some of the factors include the reduction of visits to healthcare professionals for in-person visits, cancellation of elective intracranial monitoring procedures, closure of specialized epilepsy care centers, and the diversion of resources into pandemic-centric procedures. According to the published article in the journal Neurology in May 2022, the total procedure volume in 2020 for intracranial monitoring was lower as compared to 2019. This was attributed to the fact that Epilepsy Monitoring Units (EMUs) were closed for more than 15% of the year in 2020, limiting the demand for these products and leading to a strong adverse impact on the global market.
Furthermore, the pandemic has negatively impacted the sales of these products across the globe. Prominent companies in the market reported strong sales declines in their annual revenues for FY2020. For instance, Natus Medical Incorporated witnessed a decline of -14.8% in its sub-segment of its neuro segment.
However, after the lifting of the COVID-19 restrictions, such as the reopening of EMUs, there was a resurgence in the market’s growth prospects which is expected to return to its pre-pandemic level at a steady rate.

Increased Expansion of Pipeline Studies into Newer Application Areas to Determine Market Growth
The subdural electrodes market trends can be determined by the steadily increasing demand for these products across the globe, which has significantly increased the market growth in the forecast period. As the demand for these technologies is expected to grow over the next few decades, the need for the launch of novel products across diverse clinical indications apart from the primary indication of epilepsy has led to the engagement of several established and emerging companies and institutions to increase R&D initiatives for the development.
For instance, in October 2020, Hospices Civils de Lyon in France initiated clinical trials to implant cortical electrodes in patients with head trauma, subarachnoid hemorrhage, and brain lesions. This study is considered to be an essential step in studying the clinical benefit of individualized management on the basis of such monitoring. The rising number of clinical trials in technologies is expected to strongly move forward the commercialization process of these critical medical devices. Furthermore, the large patient population base who necessitates these technologies and for whom conventional treatment options are not viable are expected to strongly boost the sales of these upcoming products.
Increasing Demand for Intracranial Monitoring as Surgical Planning for Epilepsy to Drive Market Growth
The prevalence of epilepsy is growing across the globe leading to the increasing number of surgeries; hence, intracranial monitoring is a pre-surgical planning process for epilepsy surgery. This factor is also driven by the substantial boost in the number of level 3 and level 4 dedicated specialized epilepsy centers, which exclusively provide intracranial monitoring procedures, including the implantation of these products. For instance, according to estimates published by the Centers for Disease Control and Prevention (CDC) in September 2020, in the U.S., the number of adults suffering from epilepsy stood at 3 million in 2015. Furthermore, according to the Centers for Disease Control and Prevention (CDC), the prevalence of epilepsy is increasing, primarily driven by the increase in population growth rates.
Furthermore, there is a gradual shift in the preference of epileptic patients from Anti-Epileptic Drugs (AEDs) to epilepsy surgery. According to the World Health Organization, in 2022, around 30.0% of patients on anti-epileptic medications across the globe will fail to get desired treatment outcomes for epilepsy seizure control. The failure of AEDs for seizure control is leading to an increasing number of epilepsy surgeries, which is expected to result in increased intracranial monitoring procedures for epilepsy.
Superior Procedural Outcomes of Subdural Electrodes for Locating Seizure Focus in Epilepsy to Drive Adoption
Intracranial monitoring is recommended for patients failing to get seizure control by anti-epileptic medications. To locate seizure focus and perform brain mapping, these devices are implanted in the patient's brain. Subdural electrodes enable visual mapping of seizure patterns which surgeons analyze. Moreover, they allow detailed mapping of several areas in the brain to accomplish superior procedural outcomes, eventually leading to greater adoption of intracranial monitoring and driving market growth.
There is a gradual shift in preference for depth electrodes from strip & grid electrodes. Certain benefits offered by depth electrodes, such as minimal invasion, superior visualizations, and lower postoperative complications, are expected to fuel the growth of depth electrodes, which is expected to boost the growth of the global market during the forecast period. For instance, according to a study conducted by the majority of the Epilepsy Centers in Europe in 2018, the complication rates for depth electrodes ranged between 0.5% to 5.0% during the course of intracranial monitoring.
Lack of Product Awareness in Emerging Countries to Impede Market Growth Prospects
Despite the higher prevalence of epilepsy in emerging nations, there is a huge treatment gap due to the lack of infrastructure and product availability in emerging nations. Moreover, certain factors, such as lack of awareness about surgical planning of epilepsy, social stigma about epilepsy, widespread misconceptions, and the reluctance of government authorities to promote treatment programs in emerging nations, are expected to restrain the market growth during the forecast period.
For instance, according to a study published in a Brain Science journal in 2018, in Sub-Saharan countries and Latin America, an estimated 90% of the patients don’t get access to any kind of epilepsy treatment or intracranial monitoring facility. Such limiting factors are anticipated to restrict the market growth in the forecast period.
Higher Bio-Compatibility to Boost the Adoption of Platinum Electrode
By material, the global market can be bifurcated into platinum and stainless steel.
The platinum segment is estimated to dominate the market due to various benefits it offers such as better compatibility with the organic environment, low risk of infection among patients, and better electrical conductivity over stainless steel. The stainless steel segment is expected to lose market share from 2022-2029 due to changing preference of healthcare professionals from stainless steel to platinum. Some factors of stainless steel material, such as oxidation properties and high infection rate, have impacted the segment's growth during the forecast period. Hence, healthcare professionals' preference for subdural electrodes is shifting from stainless steel to platinum.
