Asymmetric Loss of Brain Neurons Tied to Different Symptom Severity

The asymmetric loss of dopamine-producing, or dopaminergic, neurons in the brains of people with Parkinson’s disease may determine the severity of patients’ motor and cognitive symptoms, a study suggests. Such differences in the loss of these dopaminergic neurons — a characteristic feature of Parkinson’s — may explain the contrast in symptoms experienced by patients, the researchers said. Particularly, a more pronounced dopaminergic neuron loss on the right side, or hemisphere, of the brain was associated…
