> Imaging > MRI neuroimaging was obtained in all 21 patients. Most patients had conventional imaging findings, which were within normal limits, at most showing a few small nonspecific T2-bright foci in the white matter (n =9, 43%). There were 3 patients with multiple T2-bright white matter foci, which were more than expected for age, 2 mild in degree, and 1 with moderate changes. The pattern of conventional imaging findings in these cases was nonspecific with regard to the exposure/insult experienced, and the findings could perhaps be attributed to other preexisting disease processes or risk factors. Advanced structural and functional neuroimaging studies are ongoing. The study concludes that "These individuals appeared to have sustained injury to widespread brain networks without an associated history of head trauma." but its not clear to me whether that is to say the study identified specific signs of injury (the imaging section certainly doesn't indicate that) or whether it is saying the symptoms would usually be explained by injury that is as-yet unidentified https://jamanetwork.com/journals/jama/fullarticle/2673168 https://jamanetwork.com/journals/jama/fullarticle/2673168
