Clinical Report: Investigating Microstructural Changes in Brain Tissue of ME/CFS and Long COVID
Overview
This study investigates microstructural brain changes in individuals with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and long COVID using Diffusion Tensor Imaging (DTI) and Diffusion Kurtosis Imaging (DKI). Distinct alterations were identified in brain regions associated with both conditions.
Background
ME/CFS and long COVID share debilitating symptoms such as fatigue and cognitive impairment, significantly impacting patients' quality of life. Neuroimaging techniques, particularly MRI, have been employed to explore brain dysfunction in these conditions. However, no prior studies have directly compared microstructural differences between ME/CFS and long COVID using DTI and DKI.

Key Findings
ME/CFS participants exhibited microstructural alterations in the cingulum and corpus callosum.
Long COVID participants showed changes in the fusiform gyrus and precentral gyrus.
Statistical analysis revealed significant differences in the left corona radiata between ME/CFS and long COVID groups.
All findings were statistically significant with p-values < 0.05.
The study utilized advanced imaging techniques (DTI and DKI) to assess brain microstructure.
Clinical Implications
Clinicians should consider the identified microstructural changes when evaluating patients with overlapping symptoms.
Conclusion
This research identifies distinct microstructural differences in brain tissue between ME/CFS and long COVID.
