Parkinson’s disease is a progressive degenerative disorder that affects the motor or movement pathways in the brain. It is often difficult to diagnose, relying on symptoms that may appear in a number of different diseases. Early clinical symptoms may be mild such as trembling, rigidity and a general slowing down in movement. Many patients eventually have difficulty walking, talking, or completing other simple tasks, leading to a severe disruption of the body’s ability to move.

It is estimated that over 1 million Americans have Parkinson’s disease. It affects 1 in every 100 persons over the age of 60. Parkinson’s disease is not fatal, but it is progressive over time. The trend toward longer life expectancy makes it seem as if Parkinson’s disease is becoming more common because more and more people are living with its sometimes dreadful course.

More people suffer from Parkinson’s disease than suffer from Multiple Sclerosis and Muscular Dystrophy combined.

While there is currently no cure for this condition, progressive and appropriate therapy allows some patients to maintain a good function throughout their lives. Because Parkinson’s has a wide range of early symptoms that are similar to other neurological conditions, diagnosis is often difficult.

Parkinson’s disease starts in the cells of the brain that transmit the impulses that cause movement into the neurologic pathways. Dopaminergic therapy at a relatively early stage may be most effective in alleviating the symptoms of Parkinson’s disease, and may even have a long-term impact on patient mortality. Because much of the brain’s movement pathways will be compromised before symptoms even show, the disease will remain undetected and untreated for a significant period of time.

Accurate, early diagnosis of Parkinson’s disease is important to determine optimum treatments and to give the patient the best possible outcome – and PET scanning can help.
