New Clues to Easing Side Effects From Parkinson's Drug

Posted 10 days ago by

WEDNESDAY, Nov. 18, 2015 – The drug levodopa is a leading treatment for Parkinson's disease, but for most patients the medication also brings debilitating side effects. Now, scientists say animal studies are pointing to a compound that might reduce those unwanted effects. "If clinical trials confirm our preliminary findings, the eventual drug developed could make a significant improvement in the quality of life for people with Parkinson's disease," lead researcher D. James Surmeier, chair of physiology at Northwestern University School of Medicine in Chicago, said in a university news release. According to the researchers, Parkinson's disease affects more than one million Americans, and that number is expected to double by 2030. Levodopa is widely used to treat the stiffness, tremors and poor muscle control caused by the illness. But the drug can also trigger uncontrolled movement – ... Read more

Coffee Drinkers May Live Longer

Posted 12 days ago by

MONDAY, Nov. 16, 2015 – Coffee lovers may live longer than those who don't imbibe – with lower risks of early death from heart disease and neurological conditions such as Parkinson's disease, a large U.S. study finds. Researchers said the study, published online Nov. 16 in Circulation, adds to a large body of evidence on the good side of coffee. People often think of coffee-drinking as a bad habit that they need to break, said study leader Dr. Frank Hu, a professor of nutrition and epidemiology at Harvard School of Public Health in Boston. But, Hu said, many studies have linked moderate coffee intake to lower risks of developing various diseases – from heart disease and diabetes, to liver cancer, to neurological diseases such as Parkinson's, multiple sclerosis and Alzheimer's. His team's study, funded by the U.S. National Institutes of Health, adds another layer of evidence. It found ... Read more

Parkinson's Drug Shows Promise Against Macular Degeneration

Posted 16 days ago by

THURSDAY, Nov. 12, 2015 – A common Parkinson's disease medication might hold potential for preventing or treating macular degeneration, the leading cause of vision loss in the elderly, new research suggests. At this stage, no one is recommending that patients take the drug, levodopa (L-dopa), to thwart eye disease. But the findings are intriguing, researchers said. "Patients taking L-dopa for any reason are much less likely to develop age-related macular degeneration. If they do, they develop the disease much later in life than those not taking L-dopa," said study lead author Brian McKay, an associate professor of ophthalmology and vision science at the University of Arizona. However, the study doesn't actually prove that levodopa causes a lower incidence of age-related macular degeneration. It only uncovered an association between the two. Age-related macular degeneration affects ... Read more

FDA Medwatch Alert: Entacapone: Drug Safety Communication - FDA Review Found No Increased Cardiovascular Risks

Posted 28 Oct 2015 by

Including Comtan (entacapone) and Stalevo (entacapone, carbidopa, and levodopa) ISSUE: An FDA safety review has found no clear evidence of an increased risk of heart attacks, stroke, or other cardiovascular events associated with the use of entacapone for the treatment of Parkinson’s disease. As a result, recommendations for using Comtan (entacapone) and Stalevo (a combination of entacapone, carbidopa, and levodopa) will remain the same in the drug labels. FDA alerted patients and health care professionals about a possible increased risk for cardiovascular events and death with Stalevo in August 2010. This possible safety issue was observed in a clinical trial called the Stalevo Reduction in Dyskinesia Evaluation in Parkinson’s Disease (STRIDE-PD) and in a meta-analysis that combined the cardiovascular-related findings from 15 clinical trials comparing Stalevo to carbidopa/levodopa.

Finding Disease Cures Can Take Up to a Century: Analysis

Posted 24 Sep 2015 by

THURSDAY, Sept. 24, 2015 – A team of scientists has looked back over decades of discovery to conclude that it can take dozens of years, even a century, for cumulative research to lead to a cure for a single disease. The finding is disheartening given the current U.S. government underfunding of the basic science needed to investigate diseases, said a team led by Dr. R. Sanders Williams, president of the San Francisco-based Gladstone Institutes, a biomedical research organization. "As shown by our analysis, new treatments depend upon a broad base of scientific knowledge plus special contributions from a few exceptional scientists," Williams said in an institute news release. For anyone suffering from an illness, the dream word is "cure." True cures for disease remain rare, though. But, in the new study the Gladstone team traced the long investigative paths linking generations of ... Read more

Researchers Explore Memory Problems Related to Parkinson's

Posted 4 Sep 2015 by

FRIDAY, Sept. 4, 2015 – Many people with Parkinson's disease have memory problems, researchers report. The study included 40 people with early stage Parkinson's disease and 40 healthy older adults. While the disease is generally viewed as a movement disorder, about half of the Parkinson's patients had difficulty with some aspect of memory, such as learning and retaining information, or recalling spoken information, the investigators found. "And then half of those participants, or nearly one-quarter of all participants with Parkinson's, were really having a difficult time consistently with their memory, enough that it would be noticeable to other people," said study author Jared Tanner. Tanner is an assistant research professor in the department of clinical and health psychology at the University of Florida at Gainesville. Still, there was good news: Most of the Parkinson's patients did ... Read more

Common Diabetes Meds Tied to Lower Risk for Parkinson's

Posted 21 Jul 2015 by

TUESDAY, July 21, 2015 – A class of diabetes meds that include widely used drugs such as Actos and Avandia may help protect users against Parkinson's disease, a new study suggests. The study included nearly 44,600 British diabetes patients who took what are known as glitazone drugs – Avandia's generic name is rosiglitazone, while pioglitazone is the generic name for Actos. Researchers compared the medical records of those diabetes patients against the records of more than 120,000 diabetes patients who did not take a glitazone. The investigators tracked these records from 1999 – when glitazones were introduced to treat diabetes – until 2013. During that time, patients who used glitazones were 28 percent less likely to be diagnosed with Parkinson's disease than those who never took one of the meds, the study found. This association between glitazones and lower risk of Parkinson's ... Read more

Brain Chemical Dopamine May Boost Risk-Taking in Healthy People

Posted 7 Jul 2015 by

TUESDAY, July 7, 2015 – Higher levels of the brain chemical dopamine may increase risk-taking behaviors in healthy people, much like dopamine-boosting drugs have been shown to do in people with Parkinson's disease, a small new study finds. British researchers discovered that raising dopamine levels in healthy adults led to them taking greater risks when gambling. Dopamine is a neurotransmitter associated with reward-based learning. Previous research has linked drugs that increase dopamine, such as L-DOPA, with compulsive gambling in Parkinson's disease patients. The new study included 30 people. They were asked to choose between safe and risky gambling options that resulted in monetary gains and losses. They did this after receiving L-DOPA and again after receiving an inactive placebo. The participants took more risks to get bigger rewards after receiving L-DOPA, but not the placebo. ... Read more

Exercise Benefits People With Parkinson's Disease: Study

Posted 24 Jun 2015 by

WEDNESDAY, June 24, 2015 – Parkinson's disease patients who begin regular exercise earlier have a much slower decline in quality of life than those who start exercising later, a new study finds. National Parkinson Foundation (NPF) researchers looked at information from nearly 3,000 patients. More than 1,300 reported doing little regular exercise before taking part in the study. Over two years, 500 of the inactive patients began to exercise more than 2.5 hours a week. The researchers compared patients who exercised regularly for the entire two years to people who were inactive at the start of the study, but then began a regular exercise routine. The study didn't note the type of workouts, just the total amount of exercise. After two years, scores on a questionnaire that measured the impact of Parkinson's on daily life in a number of areas – including mood, movement and social ... Read more

Brain Stimulation Device Approved for Parkinson's and Essential Tremor

Posted 15 Jun 2015 by

MONDAY, June 15, 2015 – The Brio Neurostimulation System has been approved by the U.S. Food and Drug Administration to treat tremors, difficulty walking and other symptoms of Parkinson's disease and essential tremor. The implanted stimulation device is sanctioned when medication alone doesn't provide adequate relief of symptoms, the FDA said in a news release. Some 50,000 Americans are diagnosed annually with Parkinson's, and the neurological disorder affects a total of about 1 million Americans, the agency said. Typically diagnosed among people aged 60 and older, it's caused by the death or impairment of brain cells that produce the chemical dopamine. A similar condition, essential tremor, affects several million people and is usually diagnosed among people aged 40 and older. The new product consists of a battery-powered small transmitter implanted in the upper chest that's connected ... Read more

Depression Tied to Some Risk of Parkinson's Disease

Posted 20 May 2015 by

WEDNESDAY, May 20, 2015 – People with a history of depression seem to have a higher risk of developing Parkinson's disease, a large new study reports, adding to the growing body of research linking the two conditions. The Swedish study found that people diagnosed with depression were more than three times as likely as people without a history of the mood disorder to develop Parkinson's disease within the first year of depression. By 15 to 25 years later, those with depression were about 50 percent more likely to develop Parkinson's disease. "There's substantial evidence of an association with depression in the last years before a diagnosis of Parkinson's disease," said study author Peter Nordstrom, professor and chief physician in the department of Community Medicine and Rehabilitation at Umea University in Sweden. But Parkinson's experts warned that the study does not prove a ... Read more

Parkinson's Protein May Spur Immune Response

Posted 12 May 2015 by

TUESDAY, May 12, 2015 – A protein known to accumulate in Parkinson's disease and other degenerative brain disorders activates the brain's immune defenses, researchers say. The protein is called a-synuclein. The researchers noted that diseases such as Parkinson's and Lewy body dementia are characterized by the abnormal accumulation of this protein. The immune response appears to increase inflammation. The researchers said the high blood pressure drug candesartan and an experimental drug both reduce the immune response triggered by the protein. But much more research is needed on these findings. "We have made important progress in understanding how a-synuclein sets up the chronic brain inflammation that is a hallmark of these diseases," study senior author Kathleen Maguire-Zeiss, an associate professor in the department of neuroscience at Georgetown University Medical Center in ...

Ex-Baseball Star Kirk Gibson Has Parkinson's Disease

Posted 28 Apr 2015 by

TUESDAY, April 28, 2015 – Kirk Gibson, who played 17 seasons of Major League Baseball and is perhaps best known for a dramatic pinch-hit, ninth inning home run to win a World Series game in 1988, said Tuesday he has Parkinson's disease. Gibson, 57, a Michigan native who played 12 seasons with the Detroit Tigers, said in a statement that "I have faced many different obstacles in my life, and have always maintained a strong belief that no matter the circumstances, I could overcome those obstacles. "While this diagnosis poses a new kind of challenge for me, I intend to stay true to my beliefs," he added. "With the support of my family and friends, I will meet this challenge with the same determination and unwavering intensity that I have displayed in all of my endeavors in life. I look forward to being back at the ballpark as soon as possible." According to the U.S. National Institutes of ... Read more

Deep Brain Stimulation May Ease Some Parkinson's Pain for Years

Posted 23 Mar 2015 by

MONDAY, March 23, 2015 – People with Parkinson's disease who undergo deep brain stimulation may experience long-term pain relief, a small, new study from Korea suggests. However, three-quarters of the patients developed new pain in muscles and joints eight years after the procedure was performed, the researchers found. "It is potentially important that some pain types improved, but also important to understand why other types of pain did not benefit from stimulation," said Dr. Michael Okun, national medical director for the National Parkinson Foundation. Deep brain stimulation involves surgically implanting a battery pack called a neurostimulator in the brain. This sends out tiny electrical pulses to targeted areas of the brain, to block signals that cause the tremors and other motor symptoms of Parkinson's, according to the foundation. While this and other advances have helped ease ... Read more

Skin Test for Alzheimer's, Parkinson's Shows Early Promise

Posted 24 Feb 2015 by

TUESDAY, Feb. 24, 2015 – A small, early study hints that a skin test may someday be able to help diagnose people with Alzheimer's and Parkinson's diseases. Researchers found that skin biopsies can reveal elevated levels of abnormal proteins associated with the two disorders. The study is being released ahead of its presentation in April at the annual meeting of the American Academy of Neurology (AAN) in Washington, D.C. As it stands now, a definite diagnosis of Alzheimer's disease in a living person has not been possible, so the illness is often "unrecognized until after the disease has progressed," Dr. Ildefonso Rodriguez-Leyva, of the Central Hospital at the University of San Luis Potosi in Mexico, explained in an academy news release. "We hypothesized that since skin has the same origin as brain tissue while in the embryo, that they might also show the same abnormal proteins," he ... Read more
