[2015] Bryan Nguyen (Sem 2 McAdam Geo Pd 4): Parkinson's Disease

Parkinson's Disease

The two types of movement disorders are ones that cause excess movement, and ones that slow or prevent movement. Parkinson’s disease is one of the latter. Parkinson’s disease affects the nervous system, and in particular the brain (Goldstein, 2008). It damages nerves that create dopamine. Dopamine is a chemical that carries signals between the nerves in the brain that controls smooth and balanced movement (Lava, 2015).

As of 2015, there is no definite known cause of Parkinson’s Disease. There are however different factors that researchers theorize to be the cause of it. Some think that Parkinson's is because of genetics. However, only a small percentage have had a genetic abnormality identified within them. The majority have no genetic abnormalities.Another factor may be external and internal toxins, like carbon monoxide for example, that destroy dopaminergic neurons.

Oxidative stress has also been linked to parkinson’s disease. Oxidative stress refers to unstable molecules lacking a single electron, known as radicals, reacting with other molecules to replace the electron. There are mechanisms that get rid of these radicals, but for those with parkinson’s disease, the mechanisms are ineffective, or too many radicals are produced for the mechanism to handle.Finally, a combination of different medications and conditions can lead to people to getting symptoms similar to Parkinson’s Disease (Lava, 2015).

The Cause

There is no known cure to Parkinson’s disease. The symptoms are treated with medication. There is also different therapies to help with different symptoms. It is important to find a knowledgeable neurologist: one that is able to recognize your specific needs, because with a proper health team, a treatment plan can be formed (Lava, 2015).

Treatment Options

Parkinson’s disease is a progressively degenetive disease, which means it continually gets worse (Natalie, 2008). The nervous system will progressively decline as a result of it. As Parkinson's develops, more brain cells die, the symptoms get progressively worse, and non-motor symptoms begin to appear.


Examples of Therapiesphysical therapy helps mobility, flexibility and balanceoccupational therapy helps daily activitiesspeech therapy helps with voice control

Stooping posture is a common symptom for people with Parkinson's Disease.
