Transcript for The latest on COVID-19 long-term effects on the brain
And let's start with the Johns Hopkins university numbers, right now more than 100.3 million confirmed coronavirus cases in the world and 25.4 million in the U.S. And now 425,000 American lives lost to this virus. Jen, we've been focusing so much on the case counts, on the variants, and the vaccines but we're also learning about the long-term effects covid-19 may have on the brain. Head to toe, Amy. And it's so important, when we talk about case counts, we have never had to -- we can never lose sight of the individual. So let's look at the neurology right now, because we're learning more about the long-term effects of covid-19 in the brain. By observation, we know that people who have had covid-19 tend to complain, even for weeks or months, of fatigue, memory problems, anxiety, depression, even in some cases you guys, psychosis and stuttering. This study it is called neurogenic stuttering, it can occur after brain trauma. Obviously, it can occur during childhood, and then can return and we are seeing some sporadic cases of that, either a worsening of someone who has an existing stutter, or in some cases again, if they had had it in childhood. Then when you talk about these real neurologic effects, theories right now -- I have to emphasize that that's all they are. We don't know for sure is it an inflammatory response in the brain to the covid-19, and there is a theory that the virus can cross the blood/brain barrier and stimulate this reaction. But to be clear, so much unknown and this again is just one body part. Dr. Ashton, we appreciate you as always.
