There is no specific treatment for long COVID. Instead, the current approach is to deal with each symptom individually.
For example, someone who experiences brain fog may be referred by their doctor for cognitive rehabilitation, akin to physical therapy for the brain. During the rehab they might be taught ways to improve concentration or memory, or they may learn strategies to compensate for problems thinking, such as by consciously marking their place in a work task when the phone rings.
People with long COVID can be treated by their general practice physician or by individual specialists for the body parts affected by their condition, such as a cardiologist for heart issues.
Another option is to visit a clinic dedicated to long COVID care. These long COVID clinics are opening around the country, and many are affiliated with large community or academic hospitals; the website of the patient support group Survivor Corps offers a list of long COVID clinics across the United States. Still, the ratio of clinics to people grappling with symptoms is low, so many clinics have patient wait lists.
Experts agree that much more research is needed on long COVID in order to enable better care. To that end, President Biden signed an executive order in April 2022 directing a coordinated research and treatment effort by the federal government. Among other things, the order builds on a long COVID research study, called RECOVER, that is underway at the National Institutes of Health.
