Introduction paragraph

Parkinson’s Disease (PD) cannot be cured or reversed in its course. The long-term goal is to manage the symptoms, remain healthy and active, and live a relatively normal life for as long as possible. There are more that a million of people who suffer from PD in the US.

There are many ways to manage the PD, such as drug therapy. However, one has to be careful with generic drugs, especially older patients, because the differences between generic and branded drugs can be especially critical in certain circumstances. Despite the cost savings, generic tablets may not be worth it in this particular disease because what one can loose in terms of controlling PD, could be a much higher price to pay. There are also other ways to manage PD effects like exercise, diet and physical therapy. However, when treatment options fail to adequately control the symptoms of advancing PD, surgical treatment may be an option for some patients. Surgical options are still under research that’s why it’s important to do studies on animal models. There are benefits of transplanting fetal cells into brains of PD patients, but again, these techniques are still experimental and need more research. For instance, pallidotomy, is a surgical procedure that has recently increased interests because of the new animal studies that have resulted in better understanding of the pathways involved in PD, and led to new, improved surgical techniques.

There is some evidence exists that PD could have genetic trait to it when one Italian family was studied.

Studying Animal Model could be a very crucial part of understanding PD and how it works. However, it could be difficult to superimpose these studies into a human due to various distinctive factors that stand between humans and animals.
