Parkinson鈥檚 Can Lead to Anxiety and Other Non-Motor Symptoms, Even Early On
MINNEAPOLIS -
While movement problems are the main symptom of Parkinson鈥檚 disease, a new study shows that even early in the course of disease people frequently experience many non-motor symptoms such as drooling, anxiety and constipation. The study is published in the January 15, 2013, print issue of Neurology庐, the medical journal of the . 鈥淥ftentimes people with early Parkinson鈥檚 don鈥檛 even mention these symptoms to their doctors, and doctors don鈥檛 ask about them, yet many times they can be treated effectively,鈥 said study author Tien K. Khoo, PhD, of Newcastle University in the United Kingdom. The study compared 159 people with newly diagnosed Parkinson鈥檚 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鈥檚 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鈥檚 disease were drooling, urinary urgency, constipation, anxiety and a reduced sense of smell. These likely represent other symptoms of Parkinson鈥檚 that may be present even before the diagnosis is made. A total of 56 percent of the people with Parkinson鈥檚 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鈥檚 had constipation, compared to 7 percent of the control group. For anxiety, it was 43 percent compared to 10 percent. 鈥淭hese results show that Parkinson鈥檚 affects many systems in the body, even in its earliest stages,鈥 Khoo said. 鈥淥ften these symptoms affect people鈥檚 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.鈥 The study was supported by Parkinson鈥檚 UK, Newcastle University Lockhart Parkinson鈥檚 Disease Research Fund, and the UK National Institute for Health Research.
