According to the U.S. Centers for Disease Control and Prevention (CDC), about one in five adults have a health condition that might be related to having previously been infected with COVID-19. In addition to cardiovascular and respiratory conditions, blood clots and vascular issues, kidney failure, and musculoskeletal conditions, these individuals may also experience changes in their neurological and mental health conditions.

Researchers shared how their use of a special type of MRI revealed brain changes in patients up to 6 months after they have recovered from COVID-19 at the 2022 Radiological Society of North America (RSNA) annual meeting.

For their study, a team led by researchers at the Indian Institute of Technology used susceptibility-weighted imaging (SWI) 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,” the authors noted in an RSNA statement summarizing the findings. “This ability aids in the detection and monitoring of a host of neurologic conditions including microbleeds, vascular malformations, brain tumors, and stroke.”
