UNC researchers are the first to identify brain abnormalities in children at high risk for schizophrenia shortly after birth. The finding could lead to earlier detection of schizophrenia and enable better prevention and treatment. Schizophrenia is a debilitating mental disorder affecting one in 100 people worldwide. Most cases aren't detected until a person starts experiencing symptoms like delusions and hallucinations as a teenager or adult. By that time, the disease has often progressed so...

Defects in insulin function "“ which occur in diabetes and obesity "“ could directly contribute to psychiatric disorders like schizophrenia. Vanderbilt University Medical Center investigators have discovered a molecular link between impaired insulin signaling in the brain and schizophrenia-like behaviors in mice. The findings, reported June 8 in PLoS Biology, offer a new perspective on the psychiatric and cognitive disorders that affect patients with diabetes and suggest new...

Exposure to the common virus that causes cold sores may be partially responsible for shrinking regions of the brain and the loss of concentration skills, memory, coordinated movement and dexterity widely seen in patients with schizophrenia, according to research led by Johns Hopkins scientists. "We're finding that some portion of cognitive impairment usually blamed solely on the disease of schizophrenia might actually be a combination of schizophrenia and prior exposure to herpes simplex...

TITUSVILLE, N.J., May 24 /PRNewswire/ -- According to a new survey sponsored by Janssen,® Division of Ortho-McNeil-Janssen Pharmaceuticals, Inc, 80 percent of patients with schizophrenia, a chronic, severe and disabling brain disorder, say their psychiatrists do well or very well in treating them with courtesy and respect. This positive relationship is particularly important in treating schizophrenia as patients and psychiatrists must work closely together to determine...

-- Study Finds Deletions and Repeats in DNA Sequences -- PHILADELPHIA, May 10 /PRNewswire-USNewswire/ -- By analyzing the genomes of patients with schizophrenia, genetics researchers have discovered numerous copy number variations -- deletions or duplications of DNA sequences -- that increase the risk of developing schizophrenia. Significantly, many of these variations occur in genes that affect signaling among brain cells. "When we compared the genomes of patients with schizophrenia to...

Like patients, engineered mice falter at working memory tasks The strongest known recurrent genetic cause of schizophrenia impairs communications between the brain's decision-making and memory hubs, resulting in working memory deficits, according to a study in mice. "For the first time, we have a powerful animal model that shows us how genetics affects brain circuitry, at the level of single neurons, to produce a learning and memory deficit linked to schizophrenia," explained Thomas R. Insel,...

NEW YORK, NY "“ In what may provide the most compelling evidence to date, researchers at Columbia University Medical Center have illuminated how a genetic variant may lead to schizophrenia by causing a disruption in communication between the hippocampus and prefrontal cortex regions of the brain, areas believed to be responsible for carrying out working memory. Findings are published in the current online edition of Nature. This discovery coincides with the 15th anniversary of the first...

In one of the first such studies involving human patients with schizophrenia, researchers at UC Davis have provided evidence that deficits in a brain chemical may be responsible for some of the debilitating cognitive deficits "” poor attention, memory and problem-solving abilities "” that accompany the delusions and hallucinations that are the hallmarks of the disorder. The study, published online March 10 in the Journal of Neuroscience, suggests an important avenue of inquiry for...

Gene network-based analysis reveals unexpected results The underlying causes of the debilitating psychiatric disorder schizophrenia remain poorly understood. In a new study published online in Genome Research March 2, 2010, however, scientists report that a powerful gene network analysis has revealed surprising new insights into how gene regulation and age play a role in schizophrenia. Researchers are actively working to identify the direct cause of schizophrenia, likely rooted in...
