What is Parkinson's disease?

Submitted by Emma Hamilton on Sat, 10/09/2011 - 11:09pm

Parkinson's disease is a progressive disorder that causes problems with movement and balance, muscle rigidity and tremor.

It commonly occurs in people over 50 but can occur in younger age groups. 1 in 100 ageing Australians over 60 are estimated to have Parkinson’s disease (Brain Foundation Australia, 2008).

What causes Parkinson's disease is not fully known. Research is looking into the role of many risk factors including genetics, head injury and the environment.

The disorder damages nerve cells or neurons in a part of the brain that makes the important brain chemical called dopamine. Dopamine assists in movement and coordination.

Damage to cells and loss of dopamine mean there are fewer messages to and from the brain causing many of the movement problems associated with Parkinson's disease.

Parkinson's disease is a progressive degenerative disorder. This means that for most people symptoms of Parkinson's disease will get worse over time. Some common symptoms of Parkinson's disease include tremor, rigidity, poor balance and slow movement (bradykinesia).

It is important to remember that everyone experiences Parkinson's disease in their own way. The progression of Parkinson's disease is different for everyone.

There is no cure for Parkinson's disease but the symptoms of Parkinson's disease can be managed. Treatment of Parkinson's disease includes medication, surgery and other supportive therapies.
