📖 What we now know about Long COVID and our brains
❦ Globally, millions of people have contracted COVID-19 over the past few years, and some have even caught the virus two or more times.
Of more than 665 million cases worldwide, nearly one in two people with COVID-19 is at risk of developing Post-COVID-19 Neurological Syndrome (PCNS).
Symptoms of Post-COVID-19 Neurological Syndrome (PCNS) mimic some of the symptoms we see after a stroke, and younger adults seem to be at particular risk.
It’s worth noting that a link between brain health and Coronavirus infections has been known since 2006, so in this context the long-term impact of COVID-19 on the brain may arguably be the expectation rather than the exception.
Nearly one in two people who have reportedly recovered from acute COVID-19 cite disabling fatigue – that is, fatigue lasting more than twelve weeks – coupled with a series of attention and cognitive deficits similar to persistent post-stroke neurological symptoms.
We have already reported on the shared pathobiology between stroke and COVID-19 at a cellular level.
So, it should not be surprising to see the long-term impact on the brain with a persistent inflammatory response (potentially due to viral persistence, immune dysregulation or autoimmunity).
