The 12-year study included 230 people with Parkinson’s disease, of whom 211 died by the end of the research. “Remarkably, time to death for these people took anywhere from two to 37 years from diagnosis so it’s important we try to identify those risk factors that lead to an early death so we can find ways to increase a person’s life expectancy,” said Elin Bjelland Forsaa, MD, with Stavanger University Hospital in Norway and a member of the American Academy of Neurology.
The average time from the appearance of movement problems to death was 16 years. The average age at death was 81.
The study found that the risk of earlier death was increased about 1.4 times for every 10-year increase in age when symptoms began. People with psychotic symptoms, such as delusions and hallucinations, were also 1.5 times more likely to die sooner compared to those without these symptoms.
The odds of dying earlier were nearly two times higher for people who had symptoms of dementia in the study compared to those without memory problems. In addition, men were 1.6 times more likely to die earlier from the disease compared to women. Participants who scored worst on movement tests also had a higher risk of earlier death compared to those with the highest scores.
“Our findings suggest that treatments to prevent or delay the progression of movement problems, psychosis and dementia in people with Parkinson’s disease could help people live longer,” said Forsaa.
The study also found that taking antipsychotic drugs or drugs for Parkinson’s disease had no negative effect on survival.
It is estimated that about one million people in the United States have Parkinson’s disease.
The American Academy of Neurology, an association of more than 22,000 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 epilepsy, dystonia, migraine, Huntington’s disease, and dementia.For more information about the American Academy of Neurology, visit http://www.aan.com.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
