Dopamine Transporter Levels May Predict Parkinson’s Earlier

Lower levels of dopamine transporter protein in the striatum — a brain region affected significantly in Parkinson’s — may predict the development of the neurodegenerative disease up to eight years earlier in older adults carrying the most common genetic risk factor, a small study suggests. However, the observed variability in the rate of decline in dopamine transporter protein (DaT) over time, even in the same individual, may limit its use as a biomarker or a predictor…
