Based on the evidence, a pre-post test pilot study design will be implemented to clarify the benefits of an acupuncture intervention before and after treatment. The initial assessment will contain a brief demographic interview and a review of medical records, and both pre and post-intervention evaluations will comprise an imaging protocol that includes RS-fMRI, pCASL, diffusion kurtosis imaging (DKI), and a brief cognitive assessment, as described in greater detail below. Several quantitative measures within DMN regions will be generated and compared between pre- and post-acupuncture therapy. These include 1) RS-fMRI measures such as connectivity strength and fractional amplitude of low frequency fluctuations (fALFF); 2) regional CBF measured with pCASL; 3) water diffusion measures for microstructural changes with DKI.
