About Parkinson's disease

There is a broad range of movement disorders, with Parkinson’s disease being one of the most prevalent. Globally, there are over 6 million people who have Parkinson’s disease. 10% of people who are diagnosed with Parkinson’s disease are younger than 50 years.

Parkinson’s disease is a progressive disorder of the frontal lobe of the brain, the part of the brain that controls impulsive and non-impulsive movement. People with Parkinson’s have less dopamine, a chemical ‘messenger’ in the brain that sends messages to the body on how to control movement.

The main motor (or movement) related symptoms of Parkinson’s disease are bradykinesia, rigidity, tremors, postural instability. Other non-movement symptoms may be experienced such as speech and swallowing difficulties, cognitive impairment or behavioural change and sleep disturbance.

The most common treatment for Parkinson’s disease, levodopa, aims to increase the amount of dopamine in the brain. Treatment doesn’t cure the disease, but can improve symptoms to enable people with Parkinson’s to live independently and enjoy a better quality of life. Parkinson’s disease is a challenging illness and each person may experience different symptoms with varying severity.

Other Movement Disorders include Parkinsonian Tremor, Restless Legs Syndrome, Dystonia, Huntington’s disease, Progressive Supranuclear Palsy (PSP) or Wilson’s Disease.
