December 10, 2014…:1340-1349; free full text at www.ncbi.nlm.nih.gov/pmc/articles/PMC3934188/pdf/JCI71640.pdf). PD patients with LIDs demonstrate higher synaptic levels of dopamine compared to non-dyskinetic patients due to abnormal release and clearance of striatal dopamine, and it was hypothesized that this may be due in part to dopamine storage and release by non-dopaminergic terminals. Serotonergic terminals were a candidate for having a role in mishandling exo…
