An examination of white matter integrity and functional network organization in Subjective Cognitive Decline using Diffusional Kurtosis Imaging‐based tractography resting state fMRI

Subjective Cognitive Decline (SCD) may increase the risk of Alzheimer’s Disease and related dementias (ADRD). Brain network changes may occur at both the functional and structural levels in SCD. To better understand these network changes, diffusional kurtosis imaging (DKI) and functional connectome (FC) measures were examined in SCD and healthy controls (HC). We hypothesized that DKI and FC measures in the medial temporal lobe would be sensitive to differences between SCD and healthy controls (HC).
