Parkinson disease

Parkinson disease is a condition of the nervous system. It affects 1% of people over 60, but it can affect younger people as well.

In Parkinson disease, the cells that produce the chemical dopamine are destroyed. Dopamine helps with quick, co-ordinated movement. When dopamine is reduced, movements can become slow and stiff.

Parkinson disease causes shaking or tremor. It can also make it hard to start movements like walking. Later in the disease it can cause depression and dementia. If you develop a tremor or difficulty with movement, you should see your doctor.

There is no cure for Parkinson disease but medication can help with movement. It is also important to stay active. This helps to keep your muscles strong and improves your balance.

As with other conditions, it is important to have a healthy balanced diet. It can be hard to avoid losing weight if you have Parkinson disease. Swallowing can also give problems.
