Some studies reported large positive associations between accelerated epigenetic age and poorer
structural brain integrity (Davis et al., 2017; Hillary et al., 2021; Proskovec et al., 2020), while others
reported small positive associations (Milicic et al., 2022; Raina et al., 2017), and still others reported null
> associations or even associations in the opposite direction (Cheong et al., 2022; Chouliaras et al., 2018).
