As we age, we tend to accumulate “senescent cells”: these are cells that should be dead but somehow linger around. We know how to kill them selectively with some success. Recent research suggests that brain neurodegeneration might be caused by senescent brain cells. Neurons themselves do not become senescent, as far as I know, but supporting cells like astrocytes do. This suggests that we may improve brain health in older people with therapies to remove senescent cells. Similarly, senescent cells might cause osteoporosis, the phenomenon whereas the bones of older people become brittles.
