REYKJAVIK, Iceland, July 1 /PRNewswire-FirstCall/ -- The largest study of the genetics of schizophrenia ever undertaken has revealed several new common single-letter variants in the sequence of the human genome (SNPs) linked to risk of the disease. The study, by a multinational consortium of scientists led by a team from deCODE genetics (Nasdaq:DCGN), analyzed the genomes of more than 50,000 patients and control participants from fourteen countries. It is published today in the online...

U.S. researchers suggest brain white matter may help predict schizophrenia development. The study, published in Biological Psychiatry, used diffusion tensor imaging -- a form of brain imaging that detects movement of water molecules along white matter tracts -- to map brain pathways. We found that healthy subjects showed a normal and expected increase in measures indexing white matter integrity in the temporal lobe as they age, but young people at high-risk for psychosis showed no such...

White matter 'integrity' may be predictive of functional outcomeSchizophrenia, a chronic and debilitating disorder marked in part by auditory hallucinations and paranoia, can strike in late adolescence or early adulthood at a time when people are ready to stand on their own two feet as fully independent adults.Now scientists at UCLA think they are beginning to understand one important piece of this puzzle. In the first study of its kind, the researchers used a novel form of brain imaging to...

People with schizophrenia die from cancer four times as often as people in the general population. That was the conclusion of a new study published in the August 1, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study's results suggest that extra efforts should be made to improve cancer prevention and early detection in patients with schizophrenia.Schizophrenia is associated with an increased incidence of premature death, in part due to a high rate of...

When mothers become infected with influenza during their pregnancy, it may increase the risk for schizophrenia in their offspring. Influenza is a very common virus and so there has been substantial concern about this association. A new study in the June 15th issue of Biological Psychiatry, published by Elsevier suggests that the observed association depends upon a pre-existing vulnerability in the fetus.Specifically, Dr. Lauren Ellman and colleagues determined that fetal exposure to influenza...

Insight into early problems may aid understanding of disease development, diagnosis and treatment WASHINGTON "” Significant and widespread cognitive problems appear to exist in schizophrenia in its earliest phase, making it very hard for people with the disorder to work, study or be social, according to a new study published by the American Psychological Association. Understanding the early and central role of cognitive problems may help clinicians to more accurately diagnose incipient...

A U.S. study has linked a potassium brain channel gene to schizophrenia, suggesting a molecular treatment target for the mental illness. Researchers at the National Institute of Mental Health, led by Dr. Daniel Weinberger, found the expression of a previously unknown form of a potassium channel gene was 2.5 times higher than normal in the brains of people with schizophrenia. The NIMH scientists and colleagues at the National Institute on Child Health and Human Development said they found...

Blocking errant protein could stem runaway brain activity in psychosis A study on schizophrenia has implicated machinery that maintains the flow of potassium in cells and revealed a potential molecular target for new treatments. Expression of a previously unknown form of a key such potassium channel was found to be 2.5 fold higher than normal in the brain memory hub of people with the chronic mental illness and linked to a hotspot of genetic variation. An extensive series of experiments...

U.S. geneticists say they've identified a specific DNA change that is likely to increase the risk of some people developing schizophrenia. The researchers, led by Rutgers University Professor Linda Brzustowicz, said the gene, NOS1AP (previously known as CAPON) provides a potential mechanism that might be a point of entry for drug therapy, consistent with the growing trend of personalized medicine. Brzustowicz, a psychiatrist, said the research has demonstrated a functional DNA change that...

Patients with schizophrenia are able to correctly see through an illusion known as the "Ëœhollow mask' illusion, probably because their brain disconnects "Ëœwhat the eyes see' from what "Ëœthe brain thinks it is seeing', according to a joint UK and German study published in the journal NeuroImage. The findings shed light on why cannabis users may also be less deceived by the illusion whilst on the drug. People with schizophrenia, a mental illness affecting about...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
