Dopamine Clues in Autism May Signal Parkinson's Risk Later
A small study using DaT SPECT scans in 12 young adults with autism found abnormal dopamine transporter behavior in a subset, suggesting disrupted dopamine processing could be linked to a higher Parkinson's risk decades later, though no current signs of disease or IQ differences were found. Researchers caution against drawing conclusions and aim to study larger groups to verify whether these transporter abnormalities could serve as an early biomarker for Parkinson's and inform preventative strategies.
