Abbreviations: AD, Alzheimer's disease; CDR, Clinical Dementia Rating; CDR-SOB, CDR Sum of Boxes; MMSE, Mini-Mental State examination.

The AD cohort included four patients with CDR = 0.5 and nine patients with CDR = 1; Values for age are mean ± SD.

Age ranges are 49.36–77.45 and 56.22–75.56, for Alzheimer's disease patients and control participants respectively. Statistical tests were unpaired t-tests for age, education, CDR, CDR-SOB, MMSE; Fisher Exact test was used for sex, race, and handedness. Race was self-reported; one control participant and 1 patient with AD withheld from reporting race. Scores on the MMSE range from 0 to 30, with higher scores denoting better cognitive function.
