Age and disease-specific clusterings of the hippocampus and its similarity to functional differentiation into head, body and tail parcellation. In younger age the hippocampal differentiation was reminiscent of the differentiation between subiculum versus cornu ammonis (CA) 1–4 and dentate gyrus subfields. With increasing age, the lateral subregion decreased from the tail, whereas the differentiation in dementia was reminiscent of the functional differentiation into head, body and tail also suggested by the similarity estimation. Clusterings were compared using adjusted Rand Index.
