Study Links Long COVID Symptoms to Dopamine Neuron Injury in Brain
A recent study published in eBioMedicine provides strong evidence that long COVID may involve injury to dopamine-producing neurons in the brain. Researchers at Canada's Centre for Addiction and Mental Health used PET imaging to compare 24 long COVID patients with 43 healthy individuals, finding reduced dopamine markers linked to symptoms like motivation loss, slowed movement, and memory issues. This suggests long COVID could partly be a dopamine-related brain disorder, shifting focus from inflammation to new treatment possibilities targeting these neurons.
