October essay: Advance assessment of concussion
Concussion diagnosis is assessed through a variety of subjective clinical assessment tools (ex: SCAT3, SAC, BESS, Symptom checklists).17 These clinical assessment tools are often subjective in nature and largely rely on the patients’ test performance. Researchers are currently seeking out appropriate advanced concussion assessment approaches that are more objective. The following essay will outline Functional Magnetic Resonance Imaging (fMRI), Magnetic Resonance Spectroscopy (MRS), Diffusion Tensor Imaging (DTI) and Electroencephalography (EEG) as advanced imaging tools that researchers have used to outline the effects of concussion on the brain.
Functional Magnetic Resonance Imaging (fMRI):
Functional Magnetic Resonance Imaging (fMRI) is a task-based neuroimaging technique that measures brain activity by detecting changes in blood flow using blood-oxygen-level dependent (BOLD) contrast.19 Researchers have used fMRI to assess brain function following a concussive injury. Overall, researchers have found an increase in brain activation patterns in concussed patients following injury.14 12,15 Lovell et al14 used fMRI in older teens to measure the effect of brain activation patterns on concussion recovery timelines. Lovell et al14 found concussed patients who displayed an initial hyper activation following concussion demonstrated a prolonged recovery. McAllister et al15 found abnormal increases in BOLD activation…
