Cerebellar aging is spatially heterogeneous and supports cognitive resilience in later life

Nature Neuroscience, Published online: 10 June 2026; doi:10.1038/s41593-026-02289-x

The cerebellum ages unevenly, with some regions showing preservation that may help protect the brain from decline. The authors show that large cerebellar volume is associated with stronger cognitive resilience in healthy aging and Alzheimer’s disease.
