Brain aging is a relative process characterized by a progressive decline in homeostasis, stress responses and cognitive functions. At cellular level, it is associated with molecular markers such as telomere length and DNA methylation clocks, which are believed to capture different aspects of relative aging. Additionally, changes in histone modifications and gene transcription also occur. However, a complete description of epigenetic changes in middle- to old-aged brains is still missing. Here, we provide a comprehensive characterization of age-associated DNA methylation changes in the healthy
