“We’ve known for some time that these behaviors are more common in people taking certain Parkinson’s medications, but we haven’t known if the disease itself leads to an increased risk of these behaviors,” said study author Daniel Weintraub, MD, of the University of Pennsylvania Perelman School of Medicine in Philadelphia.
The study involved 168 people who had recently been diagnosed with Parkinson’s disease and had not yet taken any medications for the disease. They were compared to 143 people of similar ages who did not have the disease.
The participants were given a questionnaire asking how often they had impulse control symptoms such as compulsive gambling, shopping, sexual behavior or eating. Participants were also asked about aimless wandering, punding (which is excessive repetition of non-goal directed activity, such as continual handling and sorting of common objects) and hobbyism (the compulsive pursuit of a hobby such as collecting, cleaning or excessive Internet use).
Those with Parkinson’s disease were no more or less likely to have the impulse control symptoms than those without the disease, with about 20 percent of each group having symptoms.
“These results provide further evidence that impulse control disorders that occur in people with Parkinson’s disease are related to the exposure to the dopamine-related drugs, not just the disease itself,” Weintraub said. “More long-term studies are needed to determine if the 20 percent of people who have some symptoms of these disorders are more likely to develop impulse control disorders once they start treatment for Parkinson’s.”
The study was supported by the Parkinson’s Progression Markers Initiative, a public-private partnership funded by the Michael J. Fox Foundation for Parkinson’s Research and funding partners including Abbott, Biogen Idec., F. Hoffman-La Roche Ltd., GE Healthcare, Genentech and Pfizer Inc.

The American Academy of Neurology, an association of more than 25,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

A genetic defect protects mice from infection with influenza viruses
A new study published in the scientific journal PLOS Pathogens points out that mice lacking a protein called Tmprss2 are no longer affected by certain flu viruses.
The discovery was made by researchers from the Helmholtz Centre for Infection Research (HZI) in Braunschweig in collaboration with colleagues from Göttingen and ...
The Light: Global study gets underway with online user survey
Light has a fundamental impact on our sense of well-being and performance. In cooperation with Zumtobel, a supplier of lighting solutions, Fraunhofer IAO has launched a global user survey of lighting quality in offices. The objective is to identify the best lighting conditions for a variety of spaces and lighting ...
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
But here’s the catch: One couldn’t actually ...
A star is formed when a large cloud of gas and dust condenses and eventually becomes so dense that it collapses into a ball of gas, where the pressure heats the matter, creating a glowing gas ball – a star is born.
New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was initially about 100 times brighter than it is now. The results are published in the scientific journal, Astrophysical Journal Letters.
The young ...
