'A new study comparing magnetic resonance imaging (MRI) images of patients with
long COVID, fully recovered COVID-19 survivors, and healthy controls shows
microstructural changes in different brain regions in the long-COVID patients.
The findings will be presented next week at the annual meeting of the
Radiological Society of North America.
The research is the first to use diffusion microstructure imaging (DMI), a
novel MRI technique, which looks at the movement of water molecules in tissues.
DFI can detect smaller brain changes than traditional MRI.
MRIs have thus far failed to compare microstructural differences in the brain
of patients with long COVID, frustrating clinicians searching for a
pathophysiologic explanation of the disorder, which affects up to 10% to 15% of
COVID-19 patients.
"Diffusion microstructure imaging (DMI) is a promising approach to fill this
gap, as it detects even small volume shifts between microstructural
compartments of a neural tissue model," the authors of the study said.
The study included images from 89 patients with long COVID, 38 COVID-19
patients who didn't report long-term symptoms, and 46 healthy controls with no
history of COVID-19 infection.
Among participants with long COVID, 53% of patients could not return to their
previous level of independence and/or employment due to infection. Cognitive
performance was impaired in 41%, 78% said they had fatigue, and 73% had
impaired olfaction.'
