Still unknown, is the cause of Parkinsons disease. 9 different genetic defects have been found. Each of these nine cause the disease in 1 or a few more familes with extremely high incidences of the disease. This unfortunately hasnt take geneticists further as these familes are so rare to find. Although strong inheritance patterns are extremely rare, an person who is infected with PD is 3 to 4 times more likely to have a close relative who also has PD. Today the strongest theory for the cause of Parkinsons disease is from the combination of a subtle genetically-determined vulnerability to environmental toxins along with even limited exposure to those toxins. The toxins most strongly suspected at present are certain pesticides and industrial metals. I wish that I had an answer like many others do to the cause of Parkinsons. One thing that we know though, is that as science and technology increases, so will mans understanding of diseases such as Parkinsons. |
