Group Last MMSE Global cognition Episodic memory Semantic memory Working memory Perceptual speed Visuospatial ability

  1. AD differed from the other groups with regard to last MMSE score, global cognition, episodic memory, semantic memory, working memory, and perceptual speed. Visuospatial ability was different only between AD and AN subjects. Data are expressed as means ± SEM. Abbreviations: AD, Alzheimer's disease; AN, aged normal subjects; MCI, subjects with mild cognitive impairment; MMSE, minimental state examination. (ap < 0.05 vs. AN and MCI; bp < 0.05 vs. AN)
