Research Shows COVID-19 Affects the Brain 6 Months After Symptoms

According to a forthcoming publication to the Radiological Society of North America, researchers have discovered that COVID-19 still results in “abnormalities” in the brain six months after symptoms have subsided.

In regions of the brain linked to exhaustion, sleeplessness, anxiety, depression, headaches, and cognitive problems, they discovered abnormalities to the brain stem and front lobe.

The CDC estimates that COVID-19 will have long-term impacts in about 20% of individuals. Poor focus, migraines, and sleep issues are among the neurological symptoms of extended COVID. According to the RSNA, prolonged COVID can alter the heart, lungs, and other organs.

To identify and track neurological diseases such microbleeds, vascular malformations, brain tumours, and stroke in this study, researchers used a specialised MRI.

Despite numerous case reports indicating such abnormalities, group-level studies on COVID-19 changes in the brain’s magnetic susceptibility have not yet been conducted, according to study co-author Sapna S. Mishra, a Ph.D. candidate at the Indian Institute of Technology in Delhi, in SciTechDaily. Our research describes a novel aspect of COVID-19’s neurological effects and documents significant abnormalities in COVID survivors.

Researchers examined the imaging of 30 healthy individuals and 46 COVID recovery patients. Within six months of the recovery, the pictures were taken.

According to Mishra, variations in the susceptibility levels of different brain areas may be a sign of local compositional alterations. Lower susceptibilities may result from anomalies such calcification or a lack of iron-containing paramagnetic molecules, whereas higher susceptibilities may represent the existence of abnormal numbers of paramagnetic compounds.

To see whether the COVID-19 effects last over time, the researchers will carry out comparable investigations on the same subjects.
