The Review Article On Parkinsons Disease

Parkinson's disease is a complicated brain condition that causes the nerves to slowly break down. The exact causes and ways the disease starts are not fully understood. While a small number of cases are linked to a single gene mutation, most people with Parkinson's likely don't have a specific genetic problem. Instead, the risk for the disease is probably caused by a mix of several genes that make someone more likely to develop it. Environmental factors might also play a role in increasing the chance of getting Parkinson's, although it's not clear exactly how things like smoking, drinking coffee, or being exposed to pesticides affect the disease. In terms of how the disease affects the brain, it happens because the cells that make dopamine are lost, especially in a part of the brain called the substantia nigra. Other areas of the brain can be involved too. A key sign of Parkinson's is the presence of Lewy bodies, which are clumps made mostly of a protein called alpha-synuclein. It's not clear exactly how these clumps lead to the death of brain cells. Understanding these processes could help find new ways to treat the disease and, in the future, maybe even stop it from happening.
