Such damage is often overlooked or misdiagnosed, even with an advanced imaging technique like computed tomography (CT), say the researchers at New York University (NYU) Medical Center, who developed the device.
The device, called BrainScope, is based on the studies of E. Roy John, Ph.D., Professor of Psychiatry and Director of the Brain Research Laboratories (BRL) at NYU School of Medicine. In the late 1970s, Dr. John discovered how to translate EEG tracings — recordings of the brain’s electrical activity on an electroencephalograph — into numbers called quantitative EEGs, or QEEGs.
A significant advance, QEEGs gave scientists an objective and standardized way to assess cognitive functions. John has then established normal ranges for QEEGs across the life span and correlated deviations from these norms with a wide variety of neurological disorders, including concussions. This evidence provides the scientific basis for BrainScope.
BrainScope consists of an adhesive strip, containing six electrodes, which are connected to a mini-computer that resembles an oversized iPod. After a suspected head injury, a first responder affixes the electrode strip to the patient’s forehead. The device automatically collects a sample of the patient’s EEG and computes a large number of QEEG featureseach of which are compared to a databank of normal scores. Within minutes, BrainScope’s colour display indicates whether any of the patient’s brain functions deviate from normal.
The device is intended to be used as a triage instrument in a variety of settings, including battlefields, sporting events, emergency rooms, and clinics. BrainScope is currently in preclinical testing at three hospitals. In these tests, emergency room doctors are determining whether the device is useful in making rapid assessments of whether brain dysfunction is present.
