EEG device market seen reaching $1.91 billion by 2030

The electroencephalography devices market reached $1.3 billion in 2025 and is projected to hit $1.91 billion by 2030, driven by rising neurological disorders, aging populations and wider use of portable and wearable brain monitors. North America held the largest share in 2025, according to The Business Research Company.

Why it matters: - The EEG devices market is growing as neurological disorders rise and more health systems invest in earlier diagnosis and monitoring. - Demand is shifting toward portable, wearable and home-based testing, which could change how clinicians track brain activity outside hospitals. - The market’s projected climb to $1.91 billion by 2030 signals sustained spending on neurodiagnostic tools.

What happened: - The Business Research Company said the electroencephalography devices market reached $1.3 billion in 2025. - The market is projected to rise to $1.41 billion in 2026 and $1.91 billion by 2030. - The company said the market is forecast to grow at a 7.9% CAGR from 2026 to 2030. - North America held the largest market share in 2025. - The report also covers Asia-Pacific, South East Asia, Western Europe, Eastern Europe, South America, the Middle East and Africa. - A free sample of the market report is available. - The full electroencephalography devices market report is available online.

The details: - EEG devices record the brain’s electrical activity through electrodes placed on the scalp. - Clinicians use EEG technology to diagnose and monitor epilepsy, sleep disorders, brain injuries and other neurological diseases. - Growth over the historical period was supported by rising neurological disorder incidence, more hospital-based neurodiagnostic procedures, expansion of neurology departments and greater access to EEG diagnostic systems. - The company said future growth will be supported by an aging global population, rising demand for early neurological diagnosis, more wearable brain-monitoring devices, more diagnostic centers and higher healthcare spending on neurological care. - Key forecast-period trends include portable and wearable EEG devices, longer-duration brain monitoring, broader use in sleep and neurological diagnosis, home-based and ambulatory testing, and multi-channel systems.

Between the lines: - The report points to a market moving from traditional hospital equipment toward lighter systems that can be used for longer periods and outside clinical settings. - That shift suggests EEG testing may become more accessible for patients who need repeated monitoring or who live far from specialty centers. - The report cited a World Federation of Neurology study published in October 2023 saying more than 40% of the global population currently has a neurological condition, with the share projected to nearly double by 2050.

What's next: - The EEG market’s next growth phase will likely depend on how quickly hospitals, diagnostics providers and consumers adopt wearable and ambulatory monitoring tools. - The report’s forecast implies continued competition around portability, channel count and remote-testing capability. - Broader neurological-care spending and aging populations are likely to keep demand elevated through 2030.

The bottom line: - EEG devices are moving from a niche diagnostic category toward a larger, more flexible monitoring market with clear room for growth through 2030.
