A new study conducted at the Duke Institute for Genome and Sciences Policy suggests schizophrenia is in part caused by large, rare structural changes in DNA commonly called copy number variants, or CNVs. These new findings dismiss two decades of research that pointed to single letter alterations in DNA (SNPs) as possible candidates. Researchers at Duke scanned the genome of schizophrenia patients and healthy controls for SNPs and CNVs. None of the SNPs appeared significant, but several CNVs...

Researchers at the Johns Hopkins University School of Medicine are one gene closer to understanding schizophrenia and related disorders. Reporting in the Jan. 9 issue of the American Journal of Human Genetics, the team describes how a variation in the neuregulin 3 gene influences delusions associated with schizophrenia."Neuregulin 3 is clearly one more gene to add to the few currently known to contribute to schizophrenia," says David Valle, M.D., director of the McKusick-Nathans Institute of...

Schizophrenia may blur boundaries in the brain, causing an exaggerated focus on self, U.S. researchers suggest. A brain imaging study by researchers at the Massachusetts Institute of Technology and Harvard University found schizophrenia may blur the boundary between internal and external realities by overactivating a brain system that is involved in self-reflection -- thus causing an exaggerated focus on self. The traditional view of schizophrenia is that the disturbed thoughts, perceptions...

MIT study links schizophrenia to key 'default mode' brain systemSchizophrenia may blur the boundary between internal and external realities by overactivating a brain system that is involved in self-reflection, and thus causing an exaggerated focus on self, a new MIT and Harvard brain imaging study has found.The traditional view of schizophrenia is that the disturbed thoughts, perceptions and emotions that characterize the disease are caused by disconnections among the brain regions that...

U.S. researchers hypothesize that changes in stress hormones that occur in at-risk teenagers influence gene expression in the brain linked to mental illness. A five-year, $25-million study joins the resources of Emory University in Atlanta and seven other major research universities, with the goal of identifying more precise predictors for psychosis. "This is a critical, watershed study," Elaine Walker of Emory University said in a statement. "To date, no one has systematically studied...

People who have ongoing psychotic incidents after smoking marijuana might exhibit premature signs of schizophrenia, researchers said Monday in the Archives of General Psychiatry. "Cannabis-induced psychosis," where the person is out of touch with reality and the symptoms continue for 48 hours, is an already recognized psychiatric diagnosis, but it is divisive, Dr. Mikkel Arendt of Aarhus University in Risskov, Denmark, concludes. There has not been much research done on the condition, and...

Japanese researchers say they have found an area of the brain critical for memory is immature in mice bred to have a schizophrenic-like disorder. Professor Tsuyoshi Miyakawa of Kyoto University and Fujita Health University led the team of researchers with support from the Japan Science and Technology Agency. The scientists used mice bred to have genetic mutations that result in a range of abnormal behaviors similar to those of people with schizophrenia. The team found dentate gyrus...

By JUDY SIEGEL Women who are in the second month of pregnancy when exposed to psychological stress in a war zone or other extreme traumatic events are significantly more likely to give birth to children who eventually develop schizophrenia, according to a just-published New York University School of Medicine study of babies born in Jerusalem seven months after the Six Day War. The mental disorder, found in 1 percent of Israelis, is characterized by paranoid or bizarre delusions,...

Women pregnant in a war zone are more likely to give birth to a child who develops schizophrenia, New York researchers said. Lead author Dr. Dolores Malaspina, Anita Steckler and Joseph Steckler of the New York University School of Medicine said that the finding supports a growing body of literature that attributes maternal exposure to severe stress during the early months of pregnancy to an increased susceptibility to schizophrenia in the offspring. "The stresses in question are those...

British, German and Chinese researchers say they've determined schizophrenia is an unfortunate consequence of the rapid evolution of the human brain. The researchers, led by Philipp Khaitovich of the Max-Planck-Institute for Evolutionary Anthropology and the Shanghai branch of the Chinese Academy of Sciences, examined the brains of humans with and without schizophrenia and compared them with chimpanzee and rhesus macaque brains. Khaitovich said the scientists searched for differences in...

  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
