People with hepatitis C are nearly 30% more likely to develop Parkinson's disease than the people who did not have hepatitis.

‘Hepatitis caused specifically by the hepatitis C virus may increase the risk of developing Parkinson's disease. People with hepatitis C were nearly 30% more likely to develop the disease than people who did not have hepatitis.’

The World Health Organization estimates that 130 to 150 million people have hepatitis C worldwide. While hepatitis C can lead to serious illness, many people have few symptoms and do not realize they have the virus, especially at first. 




The virus is transmitted through sharing needles, needle stick injuries in health care providers and passed on at birth from infected mothers. In Taiwan during the time of the study, blood transfusions were the most common cause of the virus. In the United States, all donated blood has been screened for the virus since 1992.
The study involved 49,967 people with hepatitis and 199,868 people without hepatitis. Participants with hepatitis were placed into three groups: those infected with the hepatitis B virus (71%), those with hepatitis C (21%), and those who had both viruses (8%).
The participants were followed for an average of 12 years to see who developed Parkinson’s disease. Of those with hepatitis, 270 developed Parkinson’s disease, including 120 people with hepatitis C. Among those who did not have hepatitis, 1,060 developed Parkinson’s disease.
Once researchers controlled for factors such as age, sex, diabetes and cirrhosis, they found that people with hepatitis C were nearly 30% more likely to develop Parkinson’s disease than the people who did not have hepatitis.
