Sure enough, when the researchers examined the brains of PD patients, they found more cells exhibiting signs of senescence than in people without the disease — and especially astrocytes, as they had expected.7 This was true even after matching patients for age, meaning that PD subjects had even more senescent astrocytes in their SNcs than is typical for people their age (ranging in this case from 50 — 92 years at autopsy)-- and remember, aging already drives an increase in the burden of these cells as compared with young people, even in those who have yet to develop Parkinson's disease.7
