A former neuroscientist and respected health and science reporter has revealed an alarming, potential long-term symptom of COVID-19.

Paris is preparing to return to maximum coronavirus restrictions today as alarming COVID-19 infection numbers appeared to leave the French government little choice but to tighten restrictions in and around the capital.
Health minister Olivier Veran threatened Pariss trademark bars and cafes with complete closure, admitting that only improved COVID-19 infection rates could prevent such a step.
If recent trends were confirmed well have no choice, he warned late last week, saying new restrictions would mean no more family gatherings, no more evenings out, and a total closure of bars.
But a reprieve looked unlikely after France reported a 16,972 new coronavirus cases on Saturday alone, the highest daily number since the country began widespread testing.
There is no justification for denial, said the ARS director for the Paris region, Aurelien Rousseau, on Sunday. The numbers are what they are, and they are weighing heavily, he tweeted.
Interior minister Gerald Darmanin acknowledged that the looming closure of bars and cafes would be tough for everyone concerned.
We are French, we love to drink, to eat, to live, to smile and to kiss each other, he told broadcasters LCI and Europe 1 on Sunday.
But were also doing this because the people want us to, he added.
BFM television published a poll saying that 61 percent of people living in Paris and its suburbs were in favour of a complete closure of bars, which are currently authorised to remain open until 10 pm.
Paris mayor Anne Hidalgo told reporters on Sunday that its not a done deal, there is still work being done, were still talking.
But she also conceded that the health situation was very serious.
The government has said it will target primarily establishments that serve alcoholic drinks without food.
Restaurant owners are still hoping that they can dodge a similar fate, at least for now.
France’s total death toll from Covid-19 is 32,198 after recording 49 more fatalities on Saturday.
