Investigators have uncovered brain changes in patients up to six months after they recovered from COVID-19.by using a special type of MRI. This is according to a study that will be presented at the annual meeting of the Radiological Society of North America next week.
For this study, researchers used susceptibility-weighted imaging to analyze the effects that COVID-19 has on the brain. Magnetic susceptibility denotes how much certain materials, such as blood, iron, and calcium, will become magnetized in an applied magnetic field. This ability aids in the detection and monitoring of a host of neurologic conditions including microbleeds, vascular malformations, brain tumors, and stroke.
The researchers analyzed the susceptibility-weighted imaging data of 46 COVID-recovered patients and 30 healthy controls. Imaging was done within six months of recovery. Among patients with long COVID, the most commonly reported symptoms were fatigue, trouble sleeping, lack of attention, and memory issues.
“These brain regions are linked with fatigue, insomnia, anxiety, depression, headaches, and cognitive problems,” Mishra said.
