7 Important Facts to Know About Parkinson’s Disease


Most people have heard of Parkinson’s disease, but other than the mobility and tremor issues patients suffer from, they know very little about the condition. We’ve put together a list of facts about Parkinson’s disease using information from health.com and the National Parkinson Foundation.


There are more than one million people living with Parkinson’s disease in the U.S. and between 50,000 and 60,000 new cases are diagnosed each year. The disease tends to affect men more often than women.

Early Symptoms

Some of the very early symptoms of Parkinson’s disease include constipation, loss of smell, vivid dreams, and small handwriting. Later as the disease progresses, patients will suffer mobility problems and tremors.

Loss of Dopamine

Parkinson’s disease develops when cells in the substantia nigra part of the brain start to die. These cells produce dopamine which helps the brain to control movement. It’s this loss of dopamine which leads to the typical symptoms of the condition.

No Known Cause

Scientists have been unable to determine the exact cause of the disease, but it is thought that both environmental and genetic factors are involved.


Parkinson’s disease is difficult to diagnose in the early stages as there are no specific tests for the condition. Doctors will need to perform various tests and conduct a physical exam. There needs to be two of the main four symptoms of Parkinson’s disease present: shaking or tremors, slowness of movement, rigidity of the limbs or trunk, and balance issues.

Age of Onset

The average age of onset of Parkinson’s disease is 62, however many younger people develop the disease. It is called young-onset or early-onset Parkinson’s disease if the patient is younger than 50.


Treatment for Parkinson’s disease includes medications which mimic or replace dopamine in the brain and in some cases deep brain stimulation surgery. Exercise is considered an important part of treatment for the disease.

    As mother, aged almost 53 years, of twin-girls, aged 17 years, and being diagnosed already 8,5 years with Parkinson, had to give up my dreamjob…being department secretary….my live recepy is as follows… as I almost reached the top of the hill, I suddenly lost power and lost control all over…then as I saw what I acchieved in my live…I had to thank God for it…I had to live and go on for my girls and my partner….so instead of taking the highway by terms of meaning, where I was “living on”… I took a deviation/side road … which brings me also to my destination..it only takes a little more time to get there, but the things you see or come accross is worthwhile driving on that local road
