Degenerative disease is the result of a continuous process based on degenerative cell changes, affecting tissues or organs, which will increasingly deteriorate over time.
[1] In neurodegenerative diseases, cells of the central nervous system stop working or die via neurodegeneration.
[1] Many degenerative diseases exist and some are related to aging.
Normal bodily wear or lifestyle choices (such as exercise or eating habits) may worsen degenerative diseases, depending on the specific condition.
