Which part of the brain appears to be relatively spared in aging adult?

The cerebellum appears to be relatively spared in aging adults compared to other brain regions. While some age-related changes do occur in the cerebellum, such as a reduction in the number of Purkinje cells and a decline in certain neurotransmitter systems, these changes are generally less pronounced compared to other brain regions, such as the hippocampus or prefrontal cortex. As a result, the cerebellum's functions, including motor coordination, balance, and cognitive functions such as timing and sequence learning, are relatively preserved in aging adults.
