Parkinson's disease occurs when there is a loss of brain cells that secrete dopamine- a chemical that helps to control and coordinate body movements. This leads to body tremors, muscle rigidity and slow movements.
Parkinson’s disease (PD) is most commonly diagnosed in elderly people, the average diagnosis is 65 years old but young people can also have PD. Unfortunately, the cause of Parkinson’s disease is currently unknown but a lot of researches have been done to provide better understandings of PD.
The symptoms of PD is related to the decline of dopamine in the brain. Dopamine is an important chemical that functions as a messenger, allowing information to be passed between brain cells. The decline in dopamine in patients mean they can have difficulty moving and controlling their limbs.
There is no known cure for the disease but many medications and treatments are available that can manage and ease symptoms.
