Parkinson's disease is mostly observed and is more common in the persons under and above the age group of 50 years. The emergence of Parkinson's disease is idiopathic that is the cause of it is unknown. Some experts however opine that genetic factors may be responsible for this syndrome. It is estimated that the Parkinson's disease affects worldwide about five million people and in the United States, it is around one million people.

In majority of cases, the people developing Parkinson's disease are individuals aged 60 years in about 1% of the case and about 4% of those are aged 80 years. Parkinson's disease may also occur to persons aged from 21 to 40. In addition, juvenile onset of Parkinson's disease also exists in case of those whose age is below 21 years.

  • Aging is one of the riskiest factors in progression and development of Parkinson's disease with people who cross the age of 60 years are found to be afflicted by this disease.
  • Men are affected about one and half times more than women are.
  • Family history of the disorder also contributes to the development of this disease.
  • Other risk factors include exposure to pollution such as chemicals, toxins, pesticides, herbicides and any head injury or trauma and illness also results in the emergence of Parkinson's disease in some persons.(Read more on Risk Factors of Parkinson's Disease)

Demographics affected by Parkinson's Disease

The amount of research conducted by doctors and genetic biologists has led people to determine a broad spectrum of people who are most likely to be affected by Parkinson's. It is to be kept in mind that the demographics affected by Parkinson's is something that has been intensely researched. However, this is not the say- all- do- all. There are chances that anybody can develop Parkinson's. However, research has proven that people who develop Parkinson's belong to particular demographics, which helps them determine a lot of things about curing the disease.

  1. Age: There is an obvious and a direct correlation when it comes to age and Parkinson's disease. There are very few cases of people of a young age getting this disease. Usually, this disease starts affecting people who are above 50 years of age. The average age of the demographic affected by Parkinson's happens to be 60 years old. Less than 10 percentage of the reported cases of Parkinson's involves people under the age of 40.
  2. Gender and ethnicity:Parkinson's disease is said to be found more in men than in women. However, it has been found that this disease does not really have any geographic borders or even economic one. Environmental factors do not play a large role when it comes to the disease. A person could grow up in a perfect environment and still develop Parkinson's.

    However, research done on the ethnicity of the people who develop Parkinson's points towards the fact that more White Caucasians are likely to develop Parkinson's than Asians or African Americans. Why does this happen so? Scientists have not been able to determine the exact reason yet.

These are the rough demographics of people affected by Parkinson's as it has been found by the scientists. White men over the age of 40 are most likely to get the disease, whereas women are less likely to get the disease. However, this is not a bulletproof demarcation. There might be some genetic problems that might cause a young man or woman to develop the disease as well.
