Researchers at Karolinska Institutet have identified biomarkers in the blood associated with symptoms of long COVID, particularly severe respiratory disorders. The discovery can pave the way for future diagnosis and treatment. The results are published in the top-ranking scientific journal Nature Immunology.
Finding has implications for treating common neuropsychiatric disorders
Depression, schizophrenia and other mental health conditions affect 1 in 4 people in their lifetime, but mechanisms underlying these conditions are poorly understood. New research led by researchers at the University of Bristol has linked the body’s immune response with schizophrenia, Alzheimer’s disease, depression, and bipolar disorder. The study demonstrates mental health conditions might be affected by the whole body as well as changes in the brain. The findings could pave the way for better treatments of some mental health conditions.
