David Ims, a graduate student at Towson University, presented his findings, “Riding the Wave to Recovery: sLORETA QEEG in Sport Related Concussions,” at the ISNR 24th Annual Conference held in Orlando. Ims said the sLORETA analyzes electrical patterns at the surface of the scalp which reflect cortical activity, or brain waves. Working alongside neurologist Harry Kerasidis, MD, Ims used sLORETA (Standardized low-resolution brain electromagnetic tomography) three-dimensional current source density analysis to look at the effects of concussion injury in youth sports. Also known as neurofeedback measuring brain waves of activity, the study showed three patterns among the high school age student athletes within the first few days after concussion injury:
- Regionally increased slow activity usually in the temporal, parietal and frontal lobes
- Variably reduced mid-range activity in the occipital and parietal lobes
- Deregulated fast activity in a generalized pattern throughout most of the brain
“By tracing concussions impact on the brain, we can spot potential trouble from a brain functionality perspective, and assist with detection and healing timelines,” said Dr. Kerasidis. “This will lead to better outcomes for student-athletes both on and off the field of play.”
