The Parkinson disease can affect one’s capacity of controlling the movements of their body. Some nervous cells inside the brain normally produce a chemical substance called dopamine. Dopamine is a chemic mediator or neurotransmitter through which the nervous cells control the movement of the body.



In Parkinson disease, these nervous cells which produce dopamine, self destruct and lead to low amounts of dopamine. When this starts to happen, the body can start showing sign of difficulty in even the simplest movements. The Parkinson disease comes with a wide range of symptoms and complications.



Treatment of the Parkinson disease can control the symptoms in the early stages of the disease and it is applied as soon as the symptoms are affecting the daily activities and an ill person’s ability to work. For example, a right handed person who starts trembling on the left side might not feel bothered by this symptom and they might not feel the need for treatment until the symptoms start to worsen and start growing in intensity.

A person who is not able to fulfill their daily tasks because of the symptoms of Parkinson disease will want to start treatment faster than a person who does not work or who is not affected in their daily tasks by the symptoms of Parkinson disease. The symptoms of Parkinson disease are usually found on people aged 50 to 60 year old. The affection evolves slowly and sometimes can not be noticed by family, friends or even the person who has the Parkinson disease. A small number of people develop the Parkinson disease symptoms on one side of the body and most of them usually do not cross to the other side of the body.

Medication can somewhat control the symptoms of Parkinson disease, but it becomes more and more inefficient as the disease evolves. The Parkinson disease can cause a wide range of complications as the disease evolves. The connection between the Parkinson disease and the risk factors is still in question. Some of these factors can be: genetic factors, age, toxins from the environment or antioxidants. Even if research is about to reveal some answers, the experts do not know for sure what is it that causes the Parkinson disease.

There are studies, which are still in development, and that are trying to identify a cause for the Parkinson disease. Only a small percentage of the people diagnosed with the Parkinson disease have a parent, brother or sister who have this disease. However, the transmission of some abnormal genes seems to be the cause of the Parkinson disease which starts precocious in some families on which this affection is discovered at younger ages.



The low levels of dopamine- the chemic mediator- involved in the control of movements lead to the symptoms of Parkinson disease. The lack of this neurotransmitter shows up when the nervous cells from one side of the brain- the black substance- which produce dopamine start to self destruct or deteriorate. The exact cause of this affection of the nervous cells is unknown to specialist and researchers.
