Professor Shannon Weickert is uniquely motivated in her work, with her twin-brother being diagnosed with schizophrenia when he was 17 years old. To recognise the significance of this discovery Professor Shannon Weickert says you first need to understand most scientists have had a long held belief that immune cells were independent from the brain pathology in psychotic illnesses. The Breakthrough Schizophrenia Treatments You Need to Know About From long-lasting Injectables to a whole new drug class, here are the five most important cutting-edge treatments. Next, the team hopes to create mouse models with the human C4 variants associated with schizophrenia risk. This gene is C4, which is already known to play a key role in the immune system, alerting immune cells to pathogens that need to be destroyed. Next, the team set out to gain a better understanding of how certain C4 gene structures increase the risk of schizophrenia. Introducing Schizophrenia Bulletin Open. Breakthrough symptoms can include voices, delusions, paranoia, anxiety, or other depressive features. As dimensions of psychiatric diseases cross disorder boundaries, it may be that the same pathology is … The team says their findings may explain why schizophrenia tends to develop in late adolescence or early adulthood; excessive synaptic pruning caused by increased C4 activity at this point in time may trigger symptom onset.

This is a question that has challenged scientists since the disorder was first identified almost 130 years ago. “This breakthrough demonstrates the value of the NSW Government’s support for Professor Shannon Weickert as NSW Chair of Schizophrenia Research, which has delivered new insights that the community seeks,” said Professor Schofield. They aim to find out more about how C4 contributes to synaptic pruning, and to determine whether such pruning may play a role in other neurological conditions. Learn more about…, © 2004-2020 Healthline Media UK Ltd, Brighton, UK, a Red Ventures Company. This does not normally happen with most other genes, making C4 a gene of interest. Thanks to this genetic breakthrough we can finally see the potential for clinical tests, early detection, new treatments and even prevention.”. Recent Supplements. Researchers from Harvard Medical School and the Broad Institute have found the gene that may be responsible for schizophrenia. McCarroll and his colleague Aswin Sekar, an MD/PhD student at Harvard Medical School, created a novel molecular technique that enabled the team to characterize the structure of the C4 gene in the DNA samples of more than 65,000 individuals, of whom around 29,000 had schizophrenia and 36,000 did not. Desperately needed vaccines against COVID-19, developed and tested at record speed, are 2020’s breakthrough. Better heart health in midlife may lower dementia risk, Male bosses regard employee depression more negatively, Debra Sullivan, Ph.D., MSN, R.N., CNE, COI. The current treatments for schizophrenia are designed to suppress symptoms rather than target underlying causes of the disorder. Patients with schizophrenia commonly experience negative … In July 2014, the Schizophrenia Working Group of the Psychiatric Genomics Consortium – including investigators from the Stanley Center – identified more than 100 areas of the human genome that are linked to the disorder. Hallucinations Research: Into the Future, and Beyond. Cardiff University researchers make schizophrenia breakthrough . A gene called C4 plays a key role in schizophrenia development, new research finds, representing the first ever study to shed light on the biological origins of the mental illness. What causes schizophrenia? Schizophrenia is a serious mental disorder in which people interpret reality abnormally. Schizophrenia may result in some combination of hallucinations, delusions, and extremely disordered thinking and behavior that impairs daily functioning, and can be disabling.People with schizophrenia require lifelong treatment. “This opens whole new avenues for therapy, because it suggests that the pathology of schizophrenia could be within the immune cells and the immune cells could be contributing to the symptoms of schizophrenia,” said Professor Shannon Weickert. Scientists make schizophrenia breakthrough. ... on this new genetic breakthrough. The name came from the Greek words “schizo” (split) and “phren” (mind), fueling the myth that people with schizophrenia have split personalities; this is not the case. Schizophrenia Epidemiology 2017-2020 - Forecast to 2030 - ResearchAndMarkets.com. What is more, the researchers say their findings support the theory that components of the immune system play a developmental role in the brain, rather than just aiding the fight against infection. "This is a major breakthrough, we have found immune cells on the brain side of the endothelial wall, in greater amounts in people with schizophrenia and inflammation," says Weickert. Shares of Alkermes are up nicely after positive data from its schizophrenia drug trial. Talking to The Washington Post, Steven Hyman, director of the Stanley Center, hailed the research as “the most significant mechanistic study about schizophrenia ever.”, “I’m a crusty, old, curmudgeonly skeptic,” he added. By Luke Hawker PUBLISHED: 19:10, Tue, Mar 26, 2019 “It’s a clever way nature reuses the same molecules for different jobs.”.

Apr. In 2013, only 1 in 7 patients with schizophrenia met the criteria for recovery, 1 but strategies are now in place or being developed to address the many gaps and unmet needs identified in the management of schizophrenia. One in every 100 Australians lives with schizophrenia. This study changes the game. Additionally, the researchers analyzed C4 activity in almost 700 post-mortem brain samples. Last week, the headlines blared: "Schizophrenia breakthrough as genetic study reveals link to brain changes!" “These results show that it is possible to go from genetic data to a new way of thinking about how a disease develops – something that has been greatly needed.”, For some people, wearing headphones may aid sleep. And it is no wonder scientists are so excited; discovering that the C4 gene may play a key role in a person’s risk of schizophrenia may open the door to strategies that prevent the illness. In some cases, the person is already symptomatic, and due to being exposed to an extremely traumatic experience, an existing mental health condition becomes exacerbated and symptoms intensify. While the research is in its early days, the findings undoubtedly represent a breakthrough in the understanding of schizophrenia development. By Science News Staff Dec. 17, 2020 , 2:00 PM Welcome to Science’s latest crossword puzzle, marking our 2020 Breakthrough … “We have observed in people with schizophrenia, … We identified immune cells as a new player in the brain pathology of schizophrenia,” said Professor Shannon Weickert. Symptoms may come and go, but schizophrenia requires lifelong treatment. They have never been a suspect until now. It is estimated that around 21 million people across the globe have schizophrenia, with symptom onset most common in late adolescence or early adulthood. “We’re far from having a treatment based on this,” she adds, “but it’s exciting to think that one day we might be able to turn down the pruning process in some individuals and decrease their risk.”. Because the molecular origins of psychiatric diseases are little-understood, efforts by pharmaceutical companies to pursue new therapeutics are few and far between. SCIENTISTS have made a major breakthrough in the treatment for schizophrenia following one of the biggest studies of its kind. Hand weakness can occur due to many different health conditions. The researchers adapted a molecular genetics technique previously used in mouse models to study the “pruning” of synapses – the connections between brain cells, or neurons – and the role of C4 in the immune system.
