The authors propose a novel mechanism, termed Activity‐DEPendent Transpositon (ADEPT), in which epigenetic drift and the preferential use of homologous‐directed repair allows transposable elements to hijack activity‐induced double‐strand breaks in aged neurons, contributing to neurodegenerative disease.[Image: see text]

In a sample of 948 younger and older adults, we investigated whether a common Val66Met missense polymorphism (rs6265) in the BDNF gene affects the serial position curve--a fundamental phenomenon of associative memory identified by Hermann Ebbinghaus more than a century ago. We found a BDNF polymorphism effect for backward recall in older adults only, with Met-allele carriers (i.
