A new study published in The Journal of Physiology found that, compared with healthy controls, healthy young people diagnosed with COVID-19, regardless of the severity of symptoms, their nervous system There are problems
Specifically, in recently diagnosed COVID-19 patients, the sympathetic nervous system that monitors the fight or flight response appears to be abnormal (overactive in some cases, inactive in other cases)
These results are especially important considering the new evidence of symptoms such as rapid heartbeat associated with "long-term covid
This change in the "fight or flight" response, especially if prolonged, means that many processes in the body may be disrupted or affected
Understanding what happens in the body shortly after the diagnosis of COVID-19 is an important first step in understanding the potential long-term consequences of contracting the disease
Importantly, if the elderly suffer from similar flight or fight response interruptions after being infected with COVID-19, as found in young people, it may have a significant adverse effect on cardiovascular health
Researchers studied lung function, exercise capacity, blood vessel function, and neurocardiovascular control (the brain controls the heartbeat)
They used a technique called microneuroimaging.
Through these neural activities, they can evaluate the function of the sympathetic nervous system through a series of tests
Then, the subjects performed a "cold pressure test" in which they placed their hands in a mixture of ice and water (~0°C) for 2 minutes
Finally, the participants were moved to an upright position (the bed they were lying on can be tilted up and down) to observe their body's response to changes in position
Like all research on humans, this research has limitations
These findings are consistent with increasing reports of long-term covid symptoms related to fight or flight response issues
Abigail Stickford, the senior author of the study, said: “Through our collaborative project, we have followed up 6 COVID-19 subjects after they tested positive.
