Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS) are three of the major neurodegenerative diseases.
Even though neurodegenerative diseases have varied rootsâand affect distinct cell types in different brain regionsâthey do share something in common. In most of these disorders, we see some type of toxic protein accumulating in the brain. Itâs as if the brainâs garbage disposal system is blocked, letting the waste pile up. In Huntingtonâs disease, huntingtin is the disease-causing protein. In spinocerebellar ataxia, itâs the ataxins.
