Nine of these study participants had COVID infection severe enough to require prior hospitalisation. "While our study doesn't prove that COVID caused these brain changes, there appears to be a strong association with these changes and lingering neuropsychiatric symptoms," she added.įor the study, the team performed functional magnetic resonance imaging (MRI) scans on 29 patients who had COVID an average of seven months earlier and had at least one ongoing neuropsychiatric symptom like memory loss, depression, or anxiety. Deficits in the default mode network of the brain lead to increased activity in other regions to help maintain brain function," said Linda Chang, professor of diagnostic radiology and nuclear medicine at the University of Maryland School of Medicine (UMSOM). We often see such changes in patients with brain injury. "The greater activity occurred outside of the normal working memory brain network. These patients could benefit from neurorehabilitation or psychiatric treatments, and the researchers recommend that doctors consider these approaches to help manage this condition. People in the post-COVID group who have more remarkable changes in their brain activity are more likely to have poorer scores in many of these symptom domains. In addition, they have higher scores for depression, anxiety, fatigue and pain than the control group. They also report more negative feelings, such as anger and sadness, and higher stress levels, and have lower scores for life satisfaction than those who never had COVID. The study, published in the journal Neurology, also showed that people with long COVID have poorer scores on dexterity and motor endurance tests than those without COVID.
