Abbreviations: MCI = Mild Cognitive Impairment; BMI = Body Mass Index; IPAQ-E = International Physical Activity Scale for Elderly; FDDNP: 2-(1-(6-[(2-[F18]fluoroethyl)(methyl)amino]-2-naphthyl)ethylidene)malononitrile; PET: positron emission tomography.

^#MCI and SMI groups significantly different in FDDNP-PET binding levels: F(1.42) = 5.73, p = .02.
