Simply put, no.
Currently there is little known about the origins of this disease, or how to cure it. There are no blood or laboratory tests that effectively help in diagnosing PD. Diagnosis is therefore often made based on a patient’s medical history and a neurological exam. Although there is no cure as of now, there are a variety of medications that provide dramatic relief from the symptoms. Often times these medications work to restore the body’s dopamine replenishment mechanism. The most common of these medications is levodopa, or L-Dopa for short. L-Dopa is a legume-derived amino acid that has been considered the gold standard for PD treatment since the 1960s. In its time, it was one of the most important breakthroughs in the history of medicine. It has not only served to treat the 1 million people in the US who suffer from PD, but additionally research of this drug has helped in scientific advancement and understanding of neurotransmission, in particular the role of dopamine in regulating central motor function.  Unfortunately, with increased dosing and prolonged use of L-Dopa, patients experience other side effects such as dyskinesias, or spontaneous/involuntary movements when the medication unpredictably stops working for a certain amount of time. Patients need to decide at a certain point of their sickness when they wish to undergo treatment using this medication (if they so choose), knowing that they will experience a “honeymoon” phase where symptoms cease, followed by a progressive loss of motor control and other issues.
In June of 2015, the FDA approved an implantable deep brain stimulation (DBS) device known as the Brio Neurostimulation System, manufactured by St. Jude Medical Inc. DBS is a therapeutic treatment for PD, where electrical stimulators are surgically implanted into the brain and connected by electrodes to a battery-powered rechargeable pulse generator that is implanted under the skin of the upper chest.  Unfortunately, DBS is effective on a case to case basis and is not for every person with PD.
