It is the most common neurodegenerative disease. [1] Even with billions of dollars being used to find a treatment for Alzheimer's disease, no effective treatments have been found. [15] Within clinical trials stable and effective AD therapeutic strategies have a 99.5% failure rate. [16]
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 .
Arthritis, cancer, diabetes, obesity, and cognitive issues are among the most common issues faced by Americans over the age of 65. [55] Older adults who have worked in the construction industry have shown high rates of chronic diseases. [157] [163]
