We wished to evaluate if resting state fMRI could identify individuals with Parkinson disease (PD_. Analyzing the resting state and using a cross-validation approach, we were able to separate individuals with PD from controls with a 92% sensitivity and 86% specificity. Our work shows proof of concept for use of fMRI as a biomarker technique for identification of PD.
