Correlations of clinical variables and ALFF values in the AD patients.

MMSE, MoCA scores showed positive correlations with ALFF values of the SCC. Negative correlations were shown between AVLT scores and ALFF values of the hippocampus and the right ITG (P<0.05). ALFF, amplitude of low-frequency fluctuations; AD, Alzheimer’s disease; MMSE, Mini-Mental State Examination; MoCA, Montreal Cognitive Assessment; SCC, subgenual cingulate cortex; AVLT, Auditory verbal learning test; ITG, inferior temporal gyrus.
