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.

The neurovascular diseases include hemorrhage stroke, ischemic stroke, brain tumors, and more. The genetic disorders, lifestyle habits, related chronic conditions may cause the development of neurovascular diseases. During the last few years, the predominance of neurological disorders has increased significantly. For instance, epilepsy is one of the neurovascular diseases that is rising significantly across the globe.

The rising cases of brain tumors worldwide is the primary factor for the EEG devices market growth. For instance, as per the data of Lancet Neurol 2019; approximately 330 000 cases of central nervous system (CNS) cancer were reported in the world in 2016. The most regular type of essential CNS cancer is Glioma, which is a group of malignant brain tumors that includes high-grade Glioma or glioblastoma and low-grade Glioma (astrocytoma, oligodendroglioma). Thus, it is anticipated that the increasing prevalence of neurovascular diseases is likely to fuel the growth of the market during the forecast period.
