Brain Scans Reveal How Gene May Boost Schizophrenia Risk
Clues about how a suspect version of a gene may slightly increase risk for schizophrenia* are emerging from a brain imaging study by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH). The gene variant produced a telltale pattern of activity linked to production of a key brain messenger chemical. The study found that increased activity in the front of the...Scientists move forward understanding of schizophrenia
A Scots-led medical research team has identified a new gene linked to major mental illness that links back to a previously discovered gene known to increase the risk of schizophrenia and depression. Scientists from the Universities of Edinburgh and Glasgow, together with scientists from the pharmaceutical company Merck, Sharp & Dohme Limited, report the discovery of the second gene, phosphod...Prenatal exposure to famine increases risk of schizophrenia
People born during a famine in China have an increased risk of schizophrenia, consistent with previous research suggesting a link between fetal nutritional deficiency and schizophrenia, according to a study in the August 3 issue of JAMA, a theme issue on violence and human rights. Schizophrenia is a common form of severe mental illness characterized by thought disorder, hallucinations, and...Engineered mouse mimics cognitive aspects of schizophrenia
Researchers have developed a mouse strain in which the abnormal activity of the dopamine machinery in a specific part of the brain causes cognitive and behavioral impairments mimicking those in human schizophrenics. The achievement is important, because creating an animal model of any schizophrenic characteristics has not been done before. And schizophrenia's genetic and physiological comp...Studies suggest new brain protein may help in treating schizophrenia, insomnia and anxiety
A small protein in the brain that has only recently been discovered and, paradoxically, induces both profound wakefulness and a less anxious state, may represent a novel target for the treatment of psychotic behavior and schizophrenia, according to new research presented at the 6th International Congress of Neuroendocrinology (ICN 2006). ICN 2006 is being held at the David L. Lawrence Convention...Older men 'father' schizophrenics
Older fathers are more likely to have children with schizophrenia, research suggests. Men aged 50 or over are three times more likely to father a child with the illness compared to men of 27 or under. And men aged between 45 and 49 are twice as likely to have a child with schizophrenia. The scientists behind the research estimate that as many as one in four cases of schizophrenia cou...Sex exploitation connected to Schizophrenia
According to researchers linking childhood sexual abuse and schizophrenia will further confuse patients of the mental illness. According to a research in the American Journal, half of the women admitted for psychiatric care in the study// were victims of sexual abuse. The principal researcher, John Fred from Arizona University, says the figures do not prove that abuse causes schizophrenia...No explanation on schizophrenia gene
Many scientists have drawn another blank in their search for a universally applicable genetic explanation for schizophrenia, binding the case for new approaches to researching the illness. A paper by Douglas F. Levison and colleagues report that despite earlier findings to the contrary, there is no close link between schizophrenia and genes on the long arm of chromosome 1.// The resear...Gene glitches connecting pot with Schizophrenia
According to Japanese researchers, genetic abnormalities bound with marijuana-activated brain chemicals appear connected to schizophrenia. Hiroshi Ujike, a lead researcher, of the Okayama University, observed that this result supplies genetic evidence that marijuana// use can result in schizophrenia or a considerablelly increased risk of schizophrenia. Schizophrenia is one of the great...Investigational Study Evaluates the Effectiveness of Aripiprazole in Adolescents With Schizophrenia
