Penn research probes genetic underpinnings of nicotine addiction
A new study from the Abramson Cancer Center and Department of Psychiatry in the University of Pennsylvania School of Medicine shows that smokers who carry a particular version of a gene for an enzyme that regulates dopamine in the brain may suffer from concentration problems and other cognitive deficits when abstaining from nicotine - a problem... view more...

Dementia induced and blocked in Parkinson's fly model
Parkinson's disease is well-known for impairing movement and causing tremors, but many patients also develop other serious problems, including sleep disturbances and significant losses in cognitive function known as dementia. view more (2009-08-03)
Energy supplement under study for Parkinson's disease
Whether a supplement used by athletes to boost energy levels and build muscle can slow progression of Parkinson's disease is the focus of a North American study. view more (2007-03-22)
Alcoholism, smoking and genetics among Plains American Indians
Alcoholism and smoking have a high rate of co-occurrence in the general population. Yet little is known about the co-morbidity of alcoholism and smoking among American Indians. view more (2006-02-23)
Widely used cholesterol-lowering drug may prevent progression
Simvastatin, a commonly used, cholesterol-lowering drug, may prevent Parkinson's disease from progressing further. Neurological researchers at Rush University Medical Center conducted a study examining the use of the FDA-approved medication in mice with Parkinson's disease and found that the drug successfully reverses the biochemical, cellular and... view more...

Lancet study shows gene therapy for Parkinson's disease is safe and some patients benefit
A novel gene therapy technique is safe and may be effective at staving off worsening symptoms of Parkinson's disease. view more (2007-06-25)
Michigan hospital launches gene therapy study for Parkinson's disease
A Michigan hospital is embarking on a research study for advanced Parkinson's disease using a state-of-the-art treatment called gene transfer. view more (2009-10-07)
Avian influenza strain primes brain for Parkinson's disease
At least one strain of the H5N1 avian influenza virus leaves survivors at significantly increased risk for Parkinson's disease and possibly other neurological problems later in life. view more (2009-08-11)
A fading sense of smell may signal onset of Parkinson's disease
Many individuals with Parkinson's disease are able to recall losing their sense of smell well before the onset of more commonly recognized symptoms such as tremors, impaired dexterity, speech problems, memory loss and decreased cognitive ability. view more (2008-12-12)
UBC researchers develop new method to study gambling addictions
UBC researchers have created the world's first animal laboratory experiment to successfully model human gambling. view more (2009-06-17)
Brain region central to placebo effect identified
Researchers have pinpointed a brain region central to the machinery of the placebo effect-the often controversial phenomenon in which a person's belief in the efficacy of a treatment such as a painkilling drug influences its effect. view more (2007-07-19)
Stress-induced changes in brain circuitry linked to cocaine relapse
Stress-evoked changes in circuits that regulate serotonin in certain parts of the brain can precipitate a low mood and a relapse in cocaine-seeking, based on mouse studies published online this week in the Proceedings of the National Academy of Sciences. view more (2009-10-30)
Penn study finds way to prevent protein clumping characteristic of Parkinson's disease
Researchers at the University of Pennsylvania School of Medicine have identified a protein from a most unlikely source -- baker's yeast -- that might protect against Parkinson's disease. view more (2008-08-15)
Looking beyond the drug receptor for clues to drug effectiveness
Antipsychotic drugs that are widely used to treat schizophrenia and other problems may not work as scientists have assumed, according to findings from Duke University Medical Center researchers that could lead to changes in how these drugs are developed and prescribed. view more (2008-08-26)
Parkinson's mutation stunts neurons
Mutations in a key brain protein known to underlie a form of Parkinson's disease (PD) wreaks its damage by stunting the normal growth and branching of neurons, researchers have found. view more (2006-11-27)
Mouse model of Parkinson's reproduces nonmotor symptoms
The classic symptoms of Parkinson's disease involve tremor, stiffness and slow movements. Over the last decade, neurologists have been paying greater attention to non-motor symptoms, such as digestive and sleep problems, loss of sense of smell and depression. view more (2009-06-23)

Basic research into Parkinson's
Parkinson's disease was first described in 1817 by the London physician James Parkinson. A great amount of research has been carried out since that time but the fundamental causes of the disease remain unresolved. Some time ago now researchers found that a neurotransmitter, dopamine, played a key role in this illness. This is why the majority of... view more... (2004-05-07)
Daily alcohol use causes changes in sexual behavior, new study reveals
A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition. view more (2008-01-03)
UI Study Reveals Value of Schizophrenia-Related Gene Variation
University of Iowa researchers have learned more about a genetic variation that is a small risk factor for a mild form of schizophrenia, yet also is associated with improved overall survival. view more (2007-02-14)
