Advancement in Medical Devices Takes Patient Care to New Heights, Electroencephalography Devices Gain Prominence for Brain Monitoring Needs


Published Date : Feb 24, 2016

Electroencephalography refers to a neurological test, wherein electrical signals generated from the brain are recorded and deciphered. Neurological disorders such as Parkinson’s and epilepsy, among others are diagnosed through electroencephalography. Typically, an electroencephalography (EEG) setup comprises data display and data storage components using connecting wires, amplifiers, software, display device, and electrodes. Being low in cost and non-invasive for brain monitoring, EEG is gaining prominence for imaging needs.

Presently, the increasing demand for efficient brain monitoring devices is the foremost reason for the advancement of EEG and advancement of devices that are needed for this technique. Currently, EEG is available in several modalities, however, ambulatory and portable EEGs are slated to be a game changer for companies involved in the manufacture of EEG devices. Ambulatory and portable type EEG devices are utilizable for brain monitoring during surgical procedures and at the time of transfer for critical care patients. 

The opportunities that will result in business growth will benefit the top manufacturers of EEG devices, namely Cadwell Laboratories Inc., EB Neuro S.P.A., BrainScope Company Inc., Natus Medical Inc., Neurowave Systems Inc., Jordan NeuroScience Inc., Nihon Kohden Corp. Compumedics Limited, Elekta A.B., Electrical Geodesics Inc., Lifelines Neurodiagnostic Systems Inc., Bio-Signal Group Corp., and Neurosoft Ltd.

North America is the leading market for EEG devices due to high awareness among individuals for brain monitoring treatments. Nevertheless, Asia Pacific will emerge as a significant market for EEG devices displaying the highest growth rate among other geographical regions for EEG devices market.

Conventionally used for diagnosis of reasons that led to impaired brain function, EEG is finding a way for understanding animal physiology. In experiments carried out at the University of Chicago in the mid-2000, EEG devices were used on birds to find out if these creatures dreamed. However, the results obtained were inconclusive due to interference with the sleep pattern of birds as a result of sedating them with drugs to attach the necessary paraphernalia. 

Due to inconclusive results obtained using this technique, researchers set out to develop a new type of EEG in the bid to bring a revolution in reading minds using these devices. This resulted in the development of ‘Single-channel EEG’, the device that can collect signals from the brain of birds using a single electrode.
