Multiple genes contribute to risk for schizophrenia and appear to function in pathways related to transmission of signals in the brain and immunity, according to an international study led by Virginia Commonwealth University School of Pharmacy researchers. By better understanding the molecular and biological mechanisms involved with schizophrenia, scientists hope to use this new genetic information to one day develop and design drugs that are more efficacious and have fewer side effects....

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...

Gamma-aminobutyric acid (GABA) deficits have been implicated in schizophrenia and depression. In schizophrenia, deficits have been particularly well-described for a subtype of GABA neuron, the parvalbumin fast-spiking interneurons. The activity of these neurons is critical for proper cognitive and emotional functioning. It now appears that parvalbumin neurons are particularly vulnerable to oxidative stress, a factor that may emerge commonly in development, particularly in the context of...

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...

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...

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...

New computational analysis identifies gene networks affected in schizophrenia and shows that schizophrenia and autism share related genetic networks, each composed of hundreds of genes Although schizophrenia is highly genetic in origin, the genes involved in the disorder have been difficult to identify. In the past few years, researchers have implicated several genes, but it is unclear how they act to produce the disorder. A new study by researchers at Columbia University Medical Center...

Key Genes And Prototype Predictive Test For Schizophrenia Identified
2012-05-15 10:17:22

An Indiana University-led research team, along with a group of national and international collaborators, has identified and prioritized a comprehensive group of genes most associated with schizophrenia that together can generate a score indicating whether an individual is at higher or lower risk of developing the disease. Using a convergent functional genomics approach that incorporates a variety of experimental techniques, the scientists also were able to apply a panel of their top genes...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
