Gene therapy shows promise in model of Parkinson's disease
Scientists at the Ecole Polytechnique Federale de Lausanne (EPFL) in Lausanne, Switzerland, have conducted novel experiments that might one day lead to gene therapy treatment options for patients with Parkinson's disease. In research published this week in the Proceedings of the National Academy of Sciences, the research team, led by EPFL... view more... (2004-11-24)
New Guidelines Improve Diagnosis and Quality of Life for People with Parkinson Disease
New guidelines developed by the American Academy of Neurology aim to educate physicians on the diagnosis and treatment of Parkinson disease and provide people with Parkinson disease an improved quality of life. view more (2006-04-03)
MIT research holds promise for Huntington's treatment
Researchers at MIT and Harvard Medical School have identified a compound that interferes with the pathogenic effects of Huntington's disease, a discovery that could lead to development of a new treatment for the disease. view more (2006-03-09)
Blood urate levels associated with the progression of Parkinson's disease
Higher blood levels of the compound urate, a salt derived from uric acid that is associated with gout, may be associated with a slower progression of Parkinson's disease. view more (2008-04-15)
Prenatal cocaine's lasting cellular effects
Although the "crack baby" hysteria of the 1980s was greatly exaggerated, cocaine use during pregnancy can cause subtle but disabling cognitive impairments — attention deficits, learning disabilities and emotional problems. view more (2007-01-15)
Discoveries may advance stem cell therapy for Parkinson's, cancer patients
Two studies in the Jan. 27, 2006 Cell have yielded evidence that could prove a boon for stem cell therapies aimed at patients with Parkinson's disease and those with compromised immune systems due to intensive cancer therapy or autoimmune disease, according to researchers. view more (2006-01-27)
Meth exposure in young adults leads to long-term behavioral consequences
Young adults who use methamphetamine may be more vulnerable to age-related brain degeneration when they grow older, new animal research suggests. view more (2007-08-15)
Did the gene for ADHD help our nomadic ancestors?
An ADHD-associated version of the human gene DRD4 is linked to better health among nomadic tribesmen, but may cause malnourishment in their settled cousins, according to new research by a team directed by an anthropologist at the University of Wisconsin-Milwaukee (UWM). view more (2008-06-17)
Sugar can be addictive, Princeton scientist says
A Princeton University scientist will present new evidence today demonstrating that sugar can be an addictive substance, wielding its power over the brains of lab animals in a manner similar to many drugs of abuse. view more (2008-12-10)
Dissecting the machinery of nicotine's reward
Understanding what makes people crave the high of nicotine is a key to developing treatment for this highly addictive drug. And that understanding involves tracing the neural machinery by which nicotine switches on the brain's reward machinery. view more (2006-06-15)
Brain imaging and genetic studies link thinking patterns to addiction
Scientists have for the first time identified brain sites that fire up more when people make impulsive decisions. In a study comparing brain activity of sober alcoholics and non-addicted people making financial decisions, the group of sober alcoholics showed significantly more "impulsive" neural activity. view more (2007-12-26)
Gene therapy 'turns off' mutation linked to Parkinson's disease
A group of Northwestern University researchers is developing a novel gene therapy aimed at selectively turning off one of the genes involved in the development of Parkinson's disease. view more (2006-01-19)
Parkinson's Disease Mechanism Discovered
Howard Hughes Medical Institute researchers have pinpointed defects in a critical cellular pathway that can lead to the death of dopamine-producing nerve cells and ultimately symptoms of Parkinson's disease. view more (2006-06-23)
Do 'light' cigarettes deliver less nicotine to the brain than regular cigarettes?
For decades now, cigarette makers have marketed so-called light cigarettes - which contain less nicotine than regular smokes - with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain. view more (2008-09-29)
Zinc supplements could help treat ADHD
As attention deficit hyperactivity disorder (ADHD) affects around 1 in every 25 school-aged children, managing this condition is of huge social importance. An article published in BMC Psychiatry this week shows that zinc supplements could increase the effectiveness of stimulants used to treat children with the disease. The effects of ADHD on... view more... (2004-04-06)
Out-of-whack protein may boost Parkinson's
A single change in a protein may play a role in whether someone develops Parkinson's disease, say University of Florida Genetics Institute researchers writing in a recent issue of the Proceedings of the National Academy of Sciences. view more (2008-02-27)
Great expectations -- Study looks at why placebo effect varies from person to person
Why do some people experience a "placebo effect" that makes them feel better when they receive a sham treatment they believe to be real - while other people don't respond at all to the same thing, or even feel worse" view more (2007-07-19)
Drug protects brain cells in Huntington's disease model, researchers find
A drug used in some countries to treat the symptoms of Huntington's disease prevents death of brain cells in mice genetically engineered to mimic the hereditary condition, UT Southwestern Medical Center researchers have found. view more (2007-07-25)
Parkinson's approach with stem cells a promising first step
Brain cells derived from human embryonic stem cells improved the condition of rats with Parkinson's-like symptoms dramatically, but the treatment caused a significant problem - the appearance of brain tumors - that scientists are now working to solve. view more (2006-12-04)
Researchers find brain cell transplants help repair neural damage
A Swiss research team has found that using an animal's own brain cells (autologous transplant) to replace degenerated neurons in select brain areas of donor primates with simulated but asymptomatic Parkinson's disease and previously in a motor cortex lesion model, provides a degree of brain protection and may be useful in repairing brain lesions... view more...
