VOL. Share on Pinterest A new study uses a mouse model to probe the links between cannabis and schizophrenia. Physical exam. The new study included more than 62,000 people in Finland who had received a schizophrenia diagnosis at some time between 1972 and 2014. They found that levels of the synaptic protein SV2A were lower in the front parts of the brain - regions of the brain involved in planning - in people with schizophrenia. Scientists had previously … NM-MRI signal was … NIMH-funded scientists have discovered a pattern in the way a brain circuit works that may help predict the onset of psychosis. The new findings are published in the journal Brain. Associations have also been found between schizophrenia and seasonality of birth, with an excess of winter births in patients (January–March in the northern hemisphere, July–September in the southern hemisphere), particularly in urban areas [ 28 ]. firstname.lastname@example.org A new study, using … "Next we hope to scan younger people in the very early stages to see how synaptic levels change during the development of the illness and whether these changes are established early on or develop over time.". offers eligible public information officers paid access to a reliable news release distribution service. In the last 20 years, a number of studies have shown that cognitive‐behavioral psychotherapy is effective to reduce the symptoms of schizophrenia, especially when combined with … In a 2014 study, a team led by Ashley C. Proal and Dr. Lynn E. DeLisi of Harvard Medical School recruited cannabis users with and without a family history of schizophrenia… ", "Having scans that can characterise the distribution of the approximately 100 trillion synapses in the living brain, and find differences in their distribution between people with and without schizophrenia, represents a significant advance in our ability to study schizophrenia.". A recent study using Psychiatric Genomic Consortium–genome-wide association study (PGC–GWAS) data generated from 36 989 schizophrenia cases and 113 075 controls 24 has indicated a probable association of HARs with schizophrenia by demonstrating that schizophrenia-related genes are in greater proximity of HARs and are also under stronger evolutionary pressure. is a service of the American Association for the Advancement of Science. Since working memory function is often disturbed in mental disorders, such gene-hormone interactions are suspect mechanisms that may confer risk. They were followed for an average of more than 14 years. READ. Evidence from linkage studies favors disrupted-in-schizophrenia-1 (30,31), neuregulin-1 (32,33), and dysbindin (34,35) as the most promising candidate genes for schizophrenia . Drugs Targeting the Glutamate System Warrant Continued Development for Schizophrenia, Study Finds. This may be done to help rule out other problems that could be causing symptoms and to check for any related complications. CiteScore values are based on citation counts in a range of four years (e.g. The researchers, who conducted the scans at the psychiatric imaging facility at the Medical Research Council (MRC) London Institute of Medical Sciences, say these changes could underlie the cognitive difficulties seen in schizophrenia and provide targets for research into new treatments. The doctor may also request imaging studies, such as an MRI or CT scan. view more, Credit: E. Onwordi at MRC London Institute of Medical Sciences (LMS). A new study in rodents has demonstrated, for the first time, that the brain’s cerebellum plays a role in controlling reward and social preference behavior—findings that shed light on the brain circuits critical to the affective and social dysfunction seen across multiple psychiatric disorders.
