Parkinson's disease. Artwork of the silhouettes of people who have Parkinson's disease superimposed on a nerve cell (neuron) with Lewy bodies (red). Lewy bodies are deposits of a brain protein, and are found in the brain neurons of those who have Parkinson's disease. It is thought that the Lewy bodies cause the degeneration of these neurons and so cause the muscle tremors and rigid posture of those with Parkinson's disease. The disease is progressive and, though medication can control the symptoms, ultimately disabling.
