Dopamine's Double Edged Role in Long COVID A recent study published by researchers at the Centre for Addiction and Mental Health (CAMH) suggests that dopamine releasing neurons may be injured in individuals with long COVID, potentially explaining symptoms such as persistent fatigue, brain fog, and loss of motivation.
This discovery is significant because it highlights a pressing need to reevaluate our understanding of the complex interplay between dopamine, inflammation, and other physiological responses in the brain.
The study used positron emission tomography (PET) scans to examine a specific marker associated with the health and integrity of dopamine neurons in individuals with long COVID.
