By the age of 70, the human brain can shrink by about 10% from its peak size, with more significant changes often seen in specific areas like the prefrontal cortex and hippocampus. This shrinkage is associated with natural aging processes, including the loss of neurons and synapses. Factors such as genetics, lifestyle, and health conditions can influence the extent of brain shrinkage. However, cognitive function can remain intact in many individuals despite these physical changes.
