Scientific discovery may change treatment of Parkinson’s disease
When monitoring Parkinson’s disease, SPECT imaging of the brain is used for acquiring information on the dopamine activity. A new study conducted in Turku, Finland, shows that the dopamine activity observed in SPECT imaging does not reflect the number of dopamine neurons in the substantia nigra, as previously assumed. One of the most significant changes...
