In the primary study, 31 adults underwent a lumbar puncture, also referred to as a lumbar puncture, and blood tests to search for changes of their immune systems and likewise for changes in nerve cells that would affect signaling to the brain.
Among the participants, 25 people had neurocognitive symptoms of long-COVID, akin to memory loss or attention problems. Six participants had fully recovered from COVID and 17 people had never had COVID.
Those who had COVID were diagnosed between March 2020 and May 2021. Your fluid samples were collected not less than three months after the primary symptoms.

According to a Summary According to the study from the University of Gothenburg in Sweden, where the researchers work, “there were no significant differences between groups when analyzing blood and cerebrospinal fluid for immune activation or brain injury markers.” The results due to this fact suggest that the Post-COVID condition just isn't the results of persistent infection, immune activation or brain damage.”
In the second study, Norwegian researchers compared the likelihood of getting 17 different long COVID symptoms based on whether an individual was infected with COVID or not. The evaluation included 53,846 people diagnosed with COVID between February 2020 and February 2021, in addition to greater than 485,000 individuals who weren't infected.

Study results showed that folks with COVID were greater than twice as more likely to experience shortness of breath or fatigue. They were also more more likely to experience memory loss or headaches in comparison with individuals who had never had COVID. Researchers only checked out symptoms that occurred not less than three months after a COVID diagnosis.
They also found that hospitalization increased the chance of experiencing long-term COVID symptoms akin to shortness of breath, fatigue and memory loss.
