Recent neuroimaging and cellular studies link long COVID to structural damage in the dopamine system rather than widespread brain inflammation. Researchers are now exploring whether these changes, which mirror aspects of neurodegenerative disease, could be treated with dopamine-targeting therapies.

Neurological research suggests that specific anti-inflammatory and antioxidant-rich foods can support brain function and mitigate cognitive decline. Experts are also investigating how dopamine system damage contributes to long COVID symptoms.
