Subdural Electrodes Market Growth Factors

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 an article published by the World Health Organization (WHO) in February 2023, around 5.0 million people worldwide are diagnosed with epilepsy annually. In high-income countries, 49 per 100,000 people are diagnosed with epilepsy yearly. Whereas in low- and middle-income countries, 139 per 100,000 people are diagnosed with epilepsy yearly.

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 of the Product

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 an article published by the National Institutes of Health (NIH) in 2022, a pilot study was conducted to investigate the feasibility of ECoG monitoring via a less invasive burrhole approach using a Spencer-type electrode array, which was implanted subdurally rather than in the depth of the parenchyma. The study found that no adverse events related to electrode implantation were noted. The product efficacy and safety will result in strong product adoption and positively impact the market growth.

RESTRAINING FACTORS

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 an article published by the World Health Organization (WHO) in 2023, in low-income countries, around three-quarters of people with epilepsy don’t get access to any epilepsy treatment. Also, in many parts of the world, epileptic patients and their families suffer from stigma and discrimination. These factors are reducing the number of intracranial monitoring procedures in emerging countries, which will eventually reduce the product usage. Such limiting factors are anticipated to restrict the market growth in the forecast period.
