An image of a scientific news card from AuntMinnie.com displaying three brain PET scans side-by-side to highlight dopamine neuron density in the striatum. From left to right, the scans represent: • Long COVID: Shows the smallest, least intense areas of bright red and yellow, indicating a reduction in dopamine transporter binding. • Healthy, No COVID-19 History: Shows larger, highly intense crescent-shaped regions of bright red and yellow. • Healthy, COVID-19 History: Displays vibrant, thick crescent shapes of intense red and yellow, very similar to the healthy control with no history. Below the scans, a text headline reads: "Brain PET scans reveal neuron loss in long COVID". This is followed by a caption stating: "The findings suggest that treatments aimed at boosting dopamine release could be repurposed to treat long COVID."
