Parkinson's Disease
What Causes Parkinson's Disease?
Many brain cells of people with Parkinson's contain Lewy
bodies. Lewy bodies are unusual deposits or clumps of the brain
protein alpha-synuclein, along with other proteins, which
are seen upon microscopic examination of the brain. Researchers do
not yet know why Lewy bodies form or what role they play in the
development of Parkinson's. The clumps may prevent the cell from
functioning normally, or they may actually be helpful, perhaps by
keeping harmful proteins "locked up" so the cells can function.
