Infections are usually caused by an external "bug," a virus or bacteria, that grows and spreads, and is often contagious. Autopsies have shown that Lewy bodies can be in many parts of the brain but they aren't contagious. You can't catch LBD from another person. Lewy bodies occur when a normally occurring protein, alpha synuclein, "misfolds" and clumps together into sticky masses that damage nerve cells. Damage to nerve cells in different parts of the brain cause different symptoms. As the symptoms change, we can track the spread of the Lewy bodies. For example, as a person with PD begins to have hallucinations, we can see that the Lewy bodies are migrating from an area of the brain that controls mobility to one that controls visual perception.The Whitworths of Arizonahttps://www.blogger.com/profile/04887677292107869890noreply@blogger.com
