A k-means clustering approach allowed us to look for subsets of loci with transient or 'imprinted' changes in promoter methylation, looking for seven clusters, one in which no changes occur, and three each for gain and loss of DNA methylation, reasoning that this would allow us to discriminate between early, late, and transient changes between the acute and recovery stages.
Alzheimer's disease (AD) is a neurodegenerative disorder that is characterized by global cognitive decline including a progressive loss of memory, orientation and reasoning.
