Immune system activated in schizophrenia
Researchers at the Swedish medical university Karolinska Institutet have discovered that patients with recent-onset schizophrenia have higher levels of inflammatory substances in their brains. Their findings offer hope of being able to treat schizophrenia with drugs that affect the immune system. view more (2009-11-18)
ISU researchers' findings bring hope for possible Parkinson's disease cure
Researchers at Iowa State University have found an essential key to possibly cure Parkinson's disease and are looking for others. view more (2009-11-04)
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...

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)
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...

Changes in brain chemicals mark shifts in infant learning
When do you first leave the nest? Early in development infants of many species experience important transitions-such as learning when to leave the protective presence of their mother to start exploring the wider world. view more (2009-10-27)
Cocaine exposure during pregnancy leads to impulsivity in male, not female, monkeys
Adult male monkeys exposed to cocaine while in the womb have poor impulse control and may be more vulnerable to drug abuse than female monkeys, even a decade or more after the exposure, according to a new study by researchers at Wake Forest University School of Medicine. The findings could lead to a better understanding of human drug abuse. view more (2009-10-23)
Fine-tuning treatments for depression
New research clarifies how neurotransmitters like norepinephrine, serotonin, and dopamine, are regulated - a finding that may help fine-tune therapies for depression. view more (2009-10-19)
Investment in Parkinson's disease data bank yields potential therapy
Individuals with Parkinson's disease who have higher levels of a metabolite called urate in their blood and in cerebrospinal fluid (CSF) have a slower rate of disease progression. view more (2009-10-13)
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)
Worth the effort? Not if you're depressed
New research indicates that decreased cravings for pleasure may be at the root of a core symptom of major depressive disorder. The research is in contrast to the long-held notion that those suffering from depression lack the ability to enjoy rewards, rather than the desire to seek them. view more (2009-08-13)
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)
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)
Hitting cell hot spot could help thwart Parkinson's disease
The latest work to 'turn off the taps' in the brain and stop a chemical being released in excess amounts - which can lead to Parkinson's Disease - will be presented at The British Pharmacological Society's Summer Meeting in Edinburgh. view more (2009-07-08)
Rutgers Research: Parkinson's Disease Alters Patient's Ability to Learn from Rewards while Treatment Affects Ability to Learn from Negative Outcomes
A new neuropsychological memory test is helping to uncover how Parkinson's disease can alter people's ability to learn about the consequences of the choices they make. view more (2009-07-01)
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)
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)
Could hormones explain gender differences in neurological disease?
Neurological diseases including Parkinson's, Tourette's, attention deficit hyperactivity disorder (ADHD), Alzheimer's, and schizophrenia are all associated with alterations in dopamine-driven function involving the dopamine transporter (DAT). view more (2009-06-16)
PET Scans May Improve Accuracy of Dementia Diagnosis
A new study shows that the use of positron emission tomography (PET) scans may improve the accuracy of dementia diagnoses early in disease onset for more than one out of four patients. view more (2009-06-16)
Wii-hab may enhance Parkinson's treatment
The Nintendo Wii may help treat symptoms of Parkinson's disease, including depression, a Medical College of Georgia researcher says. view more (2009-06-12)
