The gene variants weaken the same receptors that some hallucinogenic drugs block New genetic factors predisposing to schizophrenia have been uncovered in five families with several affected relatives. The psychiatric disorder can disrupt thinking, feeling, and acting, and blur the border between reality and imagination. Dr. Debby W. Tsuang, professor of psychiatry and behavioral sciences, and Dr. Marshall S. Horwitz, professor of pathology, both at the University of Washington in...

Research from the University of North Carolina has shown that children at risk of developing schizophrenia have brains that function differently than those not at risk. Brain scans of children who have parents or siblings with the illness reveal a neural circuitry that is hyperactivated or stressed by tasks that peers with no family history of the illness seem to handle with ease. Because these differences in brain functioning appear before neuropsychiatric symptoms such as trouble...

Since the 1960s, psychiatrists have been hunting for substances made by the body that might accumulate in abnormally high levels to produce the symptoms associated with schizophrenia. In particular, there was a search for chemicals that might be related to the hallucinogens phencyclidine (PCP) or lysergic acid diethylamide (LSD), which could explain the emergence of psychotic symptoms in schizophrenia. This "auto-intoxication" hypothesis led investigators on a wild goose chase where...

Many lines of evidence indicate that schizophrenia is a disorder of neurodevelopment. For example, genes implicated in the heritable risk for schizophrenia are also implicated in the development of nerve cells and their connections. Numerous findings in brain imaging studies describe the changes in brain structure and function associated with schizophrenia as emerging early in the course of the disorder. Some early brain imaging studies even found little or no evidence of progression of...

Some of the dramatic differences seen among patients with schizophrenia may be explained by a single gene that regulates a group of other schizophrenia risk genes. These findings appear in a new imaging-genetics study from the Centre for Addiction and Mental Health (CAMH). The study revealed that people with schizophrenia who had a particular version of the microRNA-137 gene (or MIR137), tended to develop the illness at a younger age and had distinct brain features — both associated...

Researchers at Karolinska Institutet in Sweden have found an explanation for why the level of kynurenic acid (KYNA) is higher in the brains of people with schizophrenia or bipolar disease with psychosis. The study, which is published in the scientific periodical Molecular Psychiatry, identifies a gene variant associated with an increased production of KYNA. The discovery contributes to the further understanding of the link between inflammation and psychosis — and might pave the way for...

Birmingham Maple Clinic recently reported that a new video game under development may help treat Schizophrenia. Birmingham, MI (PRWEB) February 23, 2013 Michigan mental health providers at the Birmingham Maple Clinic recently published a blog post discussing a new project that is looking at the effectiveness of treating schizophrenia with video brain training in the form of a computer game. As noted in the post, which discusses clinical trials of brain training software currently underway...

Findings could help in early detection and intervention for people with the illness A study of eye movements in schizophrenia patients provides new evidence of impaired reading fluency in individuals with the mental illness. The findings, by researchers at McGill University in Montreal, could open avenues to earlier detection and intervention for people with the illness. While schizophrenia patients are known to have abnormalities in language and in eye movements, until recently...

Researchers at the Institute for Comprehensive Medical Science, Fujita Health University and the National Institute for Physiological Sciences, Japan, along with colleagues from 9 other institutions, have identified an exceptional mouse model of schizophrenia. After screening over 160 mutant mouse strains with a systematic battery of behavioral tests, they identified a mutant mouse lacking the Schnurri-2 protein (Shn-2 KO) that exhibits behavioral deficits and other brain features consistent...

Magnetic fields produced by the naturally occurring electrical currents in the brain could potentially be used as an objective test for schizophrenia and help to better understand the disease, according to new research published today. A team of researchers from Plymouth and Spain have used the non-invasive magnetoencephalogram (MEG) technique to find two spectral features that are significantly different in schizophrenia patients compared to healthy control subjects. Furthermore, they...
