The study compared 159 people with newly diagnosed Parkinson’s disease to 99 people of similar ages who did not have the condition. Participants were asked whether they experienced any of the 30 non-motor symptoms screened for, including sexual problems, sleep problems and gastrointestinal problems.
Those with Parkinson’s disease had an average of eight of the non-motor problems, compared to three for the people who did not have the disorder. Among the most common symptoms for those with Parkinson’s disease were drooling, urinary urgency, constipation, anxiety and a reduced sense of smell. These likely represent other symptoms of Parkinson’s that may be present even before the diagnosis is made.
A total of 56 percent of the people with Parkinson’s had problems with excess saliva or drooling, compared to 6 percent of those without the disease. A total of 42 percent of those with Parkinson’s had constipation, compared to 7 percent of the control group. For anxiety, it was 43 percent compared to 10 percent.
“These results show that Parkinson’s affects many systems in the body, even in its earliest stages,” Khoo said. “Often these symptoms affect people’s quality of life just as much if not more than the movement problems that come with the disease. Both doctors and patients need to bring these symptoms up and consider available treatments.”
The study was supported by Parkinson’s UK, Newcastle University Lockhart Parkinson’s Disease Research Fund, and the UK National Institute for Health Research.
