Another exciting study providing validation to those living with the horrific cognitive difficulties as part of long c0v!d (LC). Liu et al used PET imaging to examine dopamine neuron markers in the brains of healthy people and those affected by LC. Findings showed reduced dopamine markers in the areas responsible for motivation, memory, learning and cognition. Previous studies showed that inflammation was also present in the same area. Therefore, it is hypothesised that inflammation from LC causes damage to the dopamine system in the brain, driving the cognitive symptoms in LC, such as poor memory, lack of motivation and brain fog.
