Distributions of NDD risk classifications that are color coded and tallied based on diagnostic agreement, overt disagreement, and trending toward agreement (i.e., NDD groups classified as Likely Normal with indications consistent with the clinical diagnosis) for: (a) control group, (b) Alzheimer’s disease dementia, (c) Lewy Body dementia, (d) REM sleep behavior disorder, (e) Parkinson’s disease, and (f) mild cognitive impairment. NDD groups classified as Likely Normal with indications consistent with their clinical diagnosis were considered borderline cases and classified as trended-toward-disagreement.
