|Scientists may have found an explanation for some long COVID-19 symptoms. |
Some people who’ve had COVID-19 in the past go on to suffer memory issues and other cognitive problems long after they’ve recovered from other symptoms of the disease. Now, new research suggests that remnants of the COVID-19 virus lingering in the gut may be responsible.
Researchers think those viral remnants affect our ability to produce serotonin in the gut, where about 95% of the body’s supply of it is produced.
Serotonin is an important neurochemical that is key to several brain functions, including short-term memory. While this is one possible explanation for some long-COVID symptoms, the research study was rather small, only looking at 58 patients, so more research is still needed.
