Greater average late life physical activity relates to higher synaptic protein in brain tissue at death, with the exception of complexin-II.

Note. Dashed lines represent 95%CI. Average late life physical activity represents actigraphy levels averaged across available study visits. All models adjusted for age at death, sex, education, and average late life motor10 performances. Synaptic protein levels are expressed in log10 units, standardized, and averaged across six brain regions within each participant (z-score units).
