In addition, MD was associated with the levels of neurofilament light chain (NfL) in serum (r \> 0.22) and α-synuclein (right putamen r = 0.31), Amyloid-β 1 to 42 (Aβ42) (left hippocampus r = -0.30), phosphorylated tau at 181 threonine position (P-tau) (r \> 0.26) and total tau (T-tau) (r \> 0.23) in cerebrospinal fluid (CSF) at baseline (all P \< 0.05, FDR corrected). Furthermore, the β coefficients derived from MD and annual rate of changes in clinical score recapitulated the spatial distribution of dopamine (DAT, D1 and D2), glutamate (mGluR5 and NMDA), serotonin (5-HT1a and 5-HT2a), cannabinoid (CB1) and GABAneurotransmitter receptors/transporters (P \< 0.05, FDR corrected) derived from positron emission tomography scans in the brain of healthy volunteers.Discussion In this cohort study, cortical and subcortical MD values at baseline were associated with clinical progression and baseline fluid biomarkers, suggesting microstructural properties could be useful for stratification of patients with fast clinical progression.}, issn = {0028-3878}, URL = {//www.ez-admanager.com/content/early/2023/05/18/WNL.0000000000207408}, eprint = {//www.ez-admanager.com/content/early/2023/05/18/WNL.0000000000207408.full.pdf}, journal = {Neurology} }
