A New Tool for Detecting Brain Injury: Music Videos
What do music videos have to do with brain injuries? A new study has found that music videos can be an effective tool for detecting brain injury, because they provide an excellent media source for scientists to track eye movements.
Researchers from New York University observed brain injured and healthy subjects as they watched a 3 minute music video. The healthy subjects showed a one to one ratio of vertical to horizontal eye movements, while the brain injured subjects showed a skewed ratio (depending on which part of the brain was affected.) Using this data the researchers were able to pinpoint the location of the brain injury.
According to the CDC, around 1.4 million Americans experience a brain injury every year, and brain injuries are the number one cause of death and disability for Americans under 35. This tool’s efficiency and efficacy could be a big step in diagnosing people with brain injuries.
One of the lead scientists, Uzma Samadani, said, “When a person falls and hits their head, it can be difficult to determine whether the injury is life-threatening… eye tracking is potentially a simple, non-invasive and cost-effective way to determine quickly which patients need immediate attention.”
