MAPT and memory impairment: A recent cross-sectional study of individuals with MCI or subjective memory impairment (N = 44) reported a relationship between greater frequency of following a Mediterranean-type diet and less brain Aβ/tau burden as assessed by 2-(1-(6-[(2-[F-18]fluoroethyl)(methyl)amino]-2-naphthyl)ethylidene)malononitrile (18F-FDDNP); a pan-amyloid PET tracer that binds to both Aβ plaques and tau deposits.
