September 2023—Neurodegenerative diseases are a broad group of disorders characterized by progressive loss of nerve cells in the central or peripheral nervous system. These diseases are often chronic and incurable, with symptoms ranging from cognitive decline to motor or sensory dysfunction. There are many types of neurodegenerative diseases, with various underlying etiologies. One group of diseases, the synucleinopathies, are associated with the misfolding and aggregation of the protein α-synuclein. This group includes disease entities such as Parkinson disease, dementia with Lewy bodies, and multiple-system atrophy.
