New genetic link to high blood pressure found
A new genetic discovery made by a University of Michigan team may help explain why some people develop high blood pressure and others don't - and why some people's blood pressure increases as they age. view more (2005-10-18)
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)
Dopamine drug leads to new neurons and recovery of function in rat model of Parkinson's
In preliminary results, researchers have shown that a drug which mimics the effects of the nerve-signaling chemical dopamine causes new neurons to develop in the part of the brain where cells are lost in Parkinson's disease (PD). view more (2006-07-05)
Brain protein central to both Parkinson's, drug addiction identified
Scientists have identified a protein that appears not only to be central to the process that causes Parkinson's disease but could also play a role in muting the high from methamphetamine and other addictive drugs. view more (2009-05-05)
Interaction between gene variants may alter brain function in schizophrenia
A collaborative study led by investigators from Massachusetts General Hospital (MGH) is giving what may be the first look at how interactions between genes underlie a key symptom of schizophrenia, impaired working memory. view more (2008-11-10)
Abuse of painkillers can predispose adolescents to lifelong addiction
No child aspires to a lifetime of addiction. But their brains might. In new research to appear online in the journal Neuropsychopharmacology this week, Rockefeller University researchers reveal that adolescent brains exposed to the painkiller Oxycontin can sustain lifelong and permanent changes in their reward system - changes that increase the... view more...

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)
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)
Change in neurons' responsiveness marks newly formed sensory associations during learning
During our waking hours, our brains are inundated with sensory information that shifts from one moment to the next. view more (2005-11-08)
Disruption of gene interaction linked to schizophrenia
Disruption of the normal interaction between the genes PRODH and COMT contributes directly to major symptoms of schizophrenia by upsetting the balance of the brain chemicals glutamate and dopamine. view more (2005-12-02)
Psychopathic behaviour linked to brain chemical imbalance
Psychopathic behaviour seems to be linked to an imbalance in critical brain chemicals, reveals a study of violent and sexual offenders, reported in the Journal of Neurology Neurosurgery and Psychiatry. The findings are based on 28 men up to the age of 45, all of whom had committed violent crimes, including murder, attempted murder, aggravated... view more... (2003-06-18)
Cell-Based Therapy Shows Promise in Patients with Parkinson's Disease
A novel cell therapy using retinal pigment epithelial (RPE) cells attached to tiny gelatin bead microcarriers implanted in the brain can improve the symptoms of patients with moderate to advanced Parkinson's disease (PD). view more (2008-04-29)
Genes may make some people more prone to anxiety
Inborn differences may help explain why trauma gives some people bad memories and others the nightmare of post-traumatic stress. Scientists in Germany and the United States have reported evidence linking genes to anxious behavior. The findings appear in the August issue of Behavioral Neuroscience, published by the American Psychological... view more... (2008-08-11)
Moderate prenatal exposure to alcohol and stress in monkeys can cause touch sensitivity
A new study on monkeys has found that moderate exposure to alcohol and stress during pregnancy can lead to sensitivity to touch in the monkeys' babies. view more (2008-02-07)
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)
UCLA Find Yields Further Insight Into Causes of Parkinson's Disease
In humans, a dearth of the neurotransmitter dopamine has long been known to play a role in Parkinson's disease. It is also known that mutations in a protein called parkin cause a form of Parkinson's that is inherited. view more (2007-02-02)
The dopamine transporter gene influences alcohol withdrawal seizures
The physiological component of alcoholism is defined by tolerance and/or withdrawal: the more severe the dependency on alcohol, the more severe the clinical complications, such as greater intensity and/or complications of alcohol withdrawal. view more (2008-01-04)
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)
New treatment mechanisms for schizophrenia
The field of schizophrenia research has come alive with many exciting new potential approaches to treatment. From the introduction of chlorpromazine to the current day, all treatments approved by the U.S. Food and Drug Administration have had, at their core, a single treatment mechanism, the blockade of the dopamine D2 receptor. view more (2008-01-09)
UT Southwestern researchers discover brain's memory 'buffer' in single cells
Individual nerve cells in the front part of the brain can hold traces of memories on their own for as long as a minute and possibly longer, researchers at UT Southwestern Medical Center have found. view more (2009-01-26)
