-General

Parkinson's disease can affect a person's ability to control body movements. Certain nerve cells in the brain occur normally, a chemical called dopamine. Dopamine is a neurotransmitter or chemical mediator, through which nerve cells control body movements. In Parkinson's disease, these nerve cells that produce dopamine, are destroyed leading to low levels of it. When this happens, problems may arise in body movement.

Parkinson's disease gives a range of symptoms and complications. This article only covers the general treatment of disease rather than individual symptoms.
Treatment can control Parkinson disease symptoms in the early evolution of the disease and is started as soon as symptoms affecting daily activity and ability to work sick person. For example, a right-handed person that installs tremor on the left side may not feel embarrassed by the appearance of this symptom and cannot feel the need for treatment until symptoms are worse. A person that cannot fulfill their assignments because of the sign may want to start treatment much faster than a person who works or not or if the daily activities are not affected by of any of the symptoms.



Symptoms of the disease usually occur at people aged between 50 and 60 years. The condition develops slowly and can sometimes go unnoticed by family, friends and even the person concerned. A small number of people develop symptoms only on one side, these not progressing on the other side. Drugs can control symptoms to some extent, but along with the disease, they become increasingly ineffective. Parkinson's disease can cause a variety of complications as they evolve. The link between Parkinson's disease risk factors is still under research. These risk factors include: genetic factors, age, environmental toxins or free radicals (antioxidants). Although this research is about to reveal some answers, experts do not know for sure the cause of this disease.

-Causes

Ongoing studies are seeking to determine if there is a genetic cause of Parkinson's disease. Only a small percentage of those with Parkinson's disease have a parent, brother or sister with the disease. However, the transmission of genes (the basic unit of heredity composed of deoxyribonucleic acid) appears to be abnormal because of early-onset Parkinson's disease within families where the disease is found at much younger ages.Low levels of dopamine (mediators) involved in movement control give the symptoms of this disease. The lack of this neurotransmitter occurs when nerve cells in a certain part of the brain (black substance), which produce dopamine deteriorate or are destroyed. The exact cause of the damage to nerve cells is unknown.



-Parkinson disease symptoms

The type and severity of symptoms varies from one patient to another and according to disease stage. Symptoms that may occur in a patient in the early stages may not develop until in late stages of the disease to other patients or may not appear at all.
