How To Measure a Concussion | A Physician Neuroscientist Explains

Concussions and brain injuries are notoriously difficult to objectively measure. CT scans and MRIs simply take pictures of large structures in the brain, and they can only detect bleeding, bruising, or fractures; but they cannot measure whether the cells are damaged. IMPACT testing doesn't give you a picture at all.
However, there is a machine called a WAVi that uses EEG to measure a brain's performance. The wonderful part about a WAVi is it uses EEG, which have been around forever, it's a quick test, and how portable it is. This is my preferred method of measuring a concussion or mTBI. Any brain injury for that matter. I also use it on my neurodegenerative disease patients with Alzhiemers, Parkinsons, MS, and ALS.
It is a wonderful tool.
