New Publication on SPECT Imaging and Executive Function

A new study using PPMI data was published in the journal Movement Disorders exploring the relationship between cognitive impairment and dopaminergic deficits in unmedicated Parkinson’s patients.  Researchers used the SPECT imaging data to find evidence supporting an association with dopaminergic deficits and cognitive executive function, but not with memory and visuospatial impairment in de novo PD patients.  For the full abstract and access to the journal article, visit PubMed.
