NIH launches clinical trials to treat long COVID after months of delays

Long COVID affects millions worldwide with debilitating symptoms like fatigue, brain fog, and cardiac issues.
The NIH has faced criticism for slow action, but is now launching trials on treatments like Paxlovid and devices for cognitive issues.
Additional studies will target sleep disturbances, nervous system problems, and exercise intolerance.
The initial studies are small with only hundreds of participants, but are designed flexibly to allow for expansion.
Advocates say more urgency and funding are still needed to help long COVID patients return to normal lives.
