Aging and Neurodegeneration
The greatest risk factor for neurodegenerative diseases is aging. Mitochondrial DNA mutations as well as oxidative stress both contribute to aging. Many of these diseases are late-onset, meaning there is some factor that changes as a person ages for each disease. One constant factor is that in each disease, neurons gradually lose function as the disease progresses with age.

Famous quotes containing the word aging:
“The politics of the exile are fever,
revenge, daydream,
theater of the aging convalescent.
You wait in the wings and rehearse.
You wait and wait.”
—Marge Piercy (b. 1936)
