Head injuries can be quite dangerous if not dealt the right way. The AHEAD 300 is an EEG handheld device that was recently tested to determine whether a person with a head injury has brain bleeding. It was accurate to 97%. The device measures electrical activity in the brain and uses an algorithm to decide if a patient is having brain bleeding.
This technology is not meant to replace the CT scan in patients with mild head injury, but it provides the clinician with additional information to facilitate routine clinical decision-making. If someone with a mild head injury was evaluated on the sports or battlefield, then this test could assist in the decision of whether or not he or she needs rapid transport to the hospital.
explained Daniel Hanley Jr., M.D., the Legum Professor of Neurological Medicine and director of the Brain Injury Outcomes Program at the Johns Hopkins University School of Medicine. Of the 720 patients who tried this, 564 turned out not to have traumatic brain injuries. The cost is expected to be a faction of that of a CT scanner.
