Washington: Smoking for a greater number of years may reduce the risk of Parkinson`s disease, but smoking a larger number of cigarettes per day may not cut the risk, says a new study. The study has been published in the March 10, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology.
People who smoked for 40 or more years were 46 percent less likely to develop Parkinson`s disease than people who never smoked. Those who smoked for 30 to 39 years were 35 percent less likely to have the disease than nonsmokers. In contrast, those who smoked for one to nine years were only eight percent less likely to get the disease. The risk of developing Parkinson`s disease did not change based on how many cigarettes a person smoked per day. ANI
