Parkinson’s disease is a disease in the nervous system that affects your body movement. It belongs in the motor system disorders group (About Parkinson’s Disease). This disease can impair the person’s motor skills, speech, and writing skills (All About Parkinson's Disease). It can start off with small tremors in just one of the person’s hands, and progress to the other hand as well. Parkinson’s can affect the person’s whole body. Parkinson’s disease does not only cause tremors it could also cause stiffness or slower movements in your limbs (Dementia). Parkinson’s disease is caused by the slow deterioration of nerve cells in your brain (Causes). These nerve cells produce dopamine that helps control muscle movements throughout the body (All About Parkinson's Disease). With the death of these cells, there may not be an adequate supply of dopamine for the brain. Dopamine is a major neurotransmitter in the brain and is important in motor control, which is why Parkinson’s patients display the tremors (About Parkinson’s Disease). They do not have enough dopamine to accurately control their motor movements (Causes).
Parkinson’s disease has been around longer than we know it. Parkinson’s disease is said to date all the way back to ancient Egypt, and it has also made an appearance in the Christian Bible. There is no clear evidence of it until the 17th century (All About Parkinson's Disease). Even though it has been here for a while now, the disease was not always called Parkinson’s. In fact it was called paralysis agitans or shaking palsy when James Parkinson wrote an essay on it. It is thought that he was the first to discuss Parkinson’s disease and it was later renamed to Parkinson’s disease after him. James was not the only one to contribute to better understanding Parkinson’s disease there were many others involved. Jean-Martin Charcot, Frederic Lewy, Konstantin Nikolavitch Tretiakoff, Rolf Hassler, Arvid Carlsson, and Kazlmierz Funk all found or discovered different links, symptoms, or treatments for Parkinson’s disease. (All About Parkinson's Disease)
Parkinson’s is very hard to diagnose in younger patients (Parkinson's Disease Overview). It’s also very hard to diagnose in its early stages as well. It could take years to get the diagnosis of PD or Parkinson’s disease. Usually the patient is diagnosed first by their family doctor and referred a neurologist. There is no designed testing for PD. The diagnosis is usually dependent on clinical information and additional neurological exams if needed. Some of the test might include checking your expression, looking for tremors in your arms, stiffness in your limbs, or even regaining your balance (Diagnosis). These symptoms can determine whether someone has Parkinson’s disease or not.
Parkinson’s disease has many symptoms or characteristics. Parkinson’s is described as motor system disorder, a...

Parkinson’s disease was first discovered more than 180 years ago which now is affecting more than tens of millions people in the world (Filippo et al., 2008, para. 1). The brain can no longer control the body and people begin to experience “weakness, tremors, rigidity of the limbs, poor balance, and difficulty in initiating movements” (Carlson, 2010, p. 89). The loss of function is “caused

This is probably due to the fact the Parkinson?s disease also severely affects the patient?s motor control.Also, research is being conducted in the

The idea to study genetic disease mechanisms (e.g. Parkinson´s disease, Alzheimer´s disease, amyotrophic lateral sclerosis) is based on the generation of disease-specific induced pluripotent stem cell lines from patient´s somatic cells. These cells should have a phenotype and properties of that particular disorder enabling us to broaden our knowledge about phenotype, genetics and progression of the disease.
