Unveiling the Brain's Response to Long COVID: Insights from MRI Study
A new MRI study comparing patients with long COVID, fully recovered COVID-19 survivors, and healthy controls reveals microstructural changes in different brain regions in long-COVID patients. The study, which used diffusion microstructure imaging (DMI), a novel MRI technique, detected smaller brain changes than traditional MRI. The findings suggest a pathophysiological basis for long COVID symptoms and provide insight into the impact of COVID-19 on the brain. However, the study does not explain why some patients develop long COVID while others do not.
