Williams Draft 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…show more content…
Additionally, Keightley et al12 examined 15 concussed youth and matched controls and compared working memory and brain activity. Keightley et al12 found concussed athletes performed worse on working memory tasks, and showed significantly reduced task-related activity during performance compared to controls. Overall, fMRI has shown that increased brain activation following injury with and without performance task deficits. This can be attributed to concussed patients able to score well on tasks, but demonstrate that the simpler tasks are harder to perform. Magnetic Resonance Spectroscopy (MRS): MRS is an imaging technique used to assess metabolic changes in the brain. MRS following concussion has been used to assess the metabolite, N-acetyl Aspartate (NAA), during metabolic changes. Researchers have noted metabolic dysfunction in concussed patients.4,21,22 Cimatti et al4 examined six concussed athletes and found a decrease in NAA in most of the concussed patients. Similarly, Henry et al11 examined 12 concussed athletes and found decreased NAA in the dorsolateral prefrontal cortex and M1 areas following concussion. Additionally, Vagnozzi et al22 studied 13 concussed athletes at 3, 15, 30 and 45 days post injury and found decreased NAA in the frontal lobes that resolved within
