“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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
