A 2024 study found that SARS-CoV-2 is able to infect dopaminergic neurons, triggering an inflammatory and cellular senescence response. Such an infection in the brain's dopamine neurons may potentially explain long COVID symptoms such as brain fog and depression, an article about the study states.
The study then demonstrated that three FDA-approved drugs can reverse the senescence in these COVID infected dopamine neurons. These three drugs are:
Metformin is generally well-tolerated, but quite a few ME/CFS patients have reported a major worsening of symptoms and a major crash after just one or two tablets of metformin. So clearly some ME/CFS patients react badly to metformin, and thus anyone thinking of trying this drug might want to start with very low test doses.

- Metformin (treats diabetes)
- Riluzole (treats amyotrophic lateral sclerosis, a motor neuron disease)
- Imatinib (treats cancer)
The metformin dose was titrated over 6 days: 500 mg on day 1, 500 mg twice daily on days 2–5, then 500 mg in the morning and 1000 mg in the evening up to day 14.
