“By identifying risk factors, it may help guide treatment decisions, allow for early intervention and possibly reduce disability,” said study author Kevin Biglan, MD, MPH, with University of Rochester School of Medicine in Rochester, NY, and member of the American Academy of Neurology.
For the study, researchers reviewed the results of a four-year clinical trial involving 301 people with an average age of 61 who had early Parkinson’s disease. Half of the group received the drug levodopa; the other half took pramipexole. No one reported having hallucinations at the beginning of the study.
The study found nearly one-fifth developed hallucinations, more than one-third of the participants developed sleepiness, and nearly half developed swelling within four years of starting treatment. Multiple health problems, along with age, gender, initial type of treatment and cognitive status were identified as risk factors.
“In contrast to other studies, we found being male, having multiple health problems and taking pramipexole were independently associated with developing sleepiness,” said Biglan. “This is the first time a patient’s other health problems have been identified as a risk factor for drowsiness.”
The study also found being older, having more multiple health problems and the presence of slight memory problems were associated with an increased risk of hallucinations; type of treatment did not affect the risk.
Being female, having heart disease and pramipexole treatment was associated with an increased risk of swelling.
“Our results suggest that other illnesses are important, yet overlooked risk factors for the development of sleep problems, swelling, and hallucinations in early Parkinson’s disease and should be considered when talking to patients about the risks of treatment,” said Biglan. “When beginning pramipexole, doctors should explain the risks and monitor patients closely for sleep issues and swelling.”

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
