Electroencephalography (EEG) Devices for Early Diagnosis of Brain Disorders

Geriatric populace is highly susceptible to neurological disorders. Electroencephalography systems & devices play a vital role in detecting such disorders. Advancements in these medical equipment can expand their reach to other fields.

What are EEG Devices?

Electroencephalography (EEG) can record electrical impulses emitted by the brain. According to a World Health Organization (WHO) study, more than 50 million people are suffering from epilepsy. EEG devices and systems can be utilized to detect the early signs of epilepsy and other neurological disorders such as brain tumor, Motor Neurone Disease (MND), Alzheimer’s disease, and others.


Communication Using BCI

Brain computer interface (BCI) technology acts as a communicator between the brain and an external device. Recently, scientists have conducted an experiment on a group of paraplegics to test their responses to BCI. These patients of spinal cord injuries were taught to walk with the help of a robotic exoskeleton and their responses were recorded with EEG devices. Another study conducted by BrainScope Company Inc. showed the efficiency of its EEG device, AHEAD 300. It can predict the severity of head injuries with nearly 90% accuracy.

Portable Devices

According to a recent study by a team of scientists from Germany, China, and U.S., a brain-reading machine was able to interpret blinking signals into appropriate brain waves in patients with MND. The success of such trials could culminate in the use of EEG machines for other disorders as well. Corporations are keen on manufacturing portable EEGs to target small scale researchers. NeuroSky Mindwave and Emotiv Epoc are some examples of such handheld devices.

Market Overview

The worldwide electroencephalography (EEG) systems/devices market is projected to attain nearly USD 1.4 billion by 2025, according to Grand View Research, Inc. It is anticipated to expand at around 7.6% CAGR over the forecast period (2014 to 2025). The market is driven by the effectiveness of EEG devices and high prevalence of neurological disorders.

The 32-channel EEG devices are expected to continue dominating the global market over the forecast period due to technological breakthroughs and rising adoption. Portable EEG devices are expected to register a lucrative growth till 2025. In 2015, North America led the global market, followed by Asia Pacific and Europe. Notable market players are Natus Medical, Inc.; Cadwell Laboratories, Inc.; Noraxon U.S.A., Inc.; and Medtronic.
