Increasingly, though, this area of research has focused on the heightened emotional reactivity observed in patients carrying this diagnosis, as well as the high rates with which they also meet diagnostic criteria for posttraumatic stress disorder and mood disorders. http://medicalxpress.com/news/2013-01-borderline-personality-disorder-storm-emotion.html Psychology & Psychiatry Tue, 15 Jan 2013 09:02:25 EST news277462886 The scientific community have long debated the causal relationship between cannabis use and the risk factor for psychotic illnesses such as schizophrenia. Both sides of this controversial subject are put forward in two articles published today in F1000 Medicine Reports. To give rise to the debate, the authors of each article were given the opportunity to read the opposing side's article drafts and consider their arguments when structuring their own article. http://medicalxpress.com/news/2013-01-cannabis-psychosis-debate.html Psychology & Psychiatry Fri, 11 Jan 2013 09:53:15 EST news277120387 Patients with mental illness visiting emergency departments in Ontario have shorter waits to see a doctor during crowded periods and only slightly longer waits during less busy periods, found a study in CMAJ (Canadian Medical Association Journal). http://medicalxpress.com/news/2012-11-psychiatric-emergency-departments.html Psychology & Psychiatry Mon, 12 Nov 2012 12:00:11 EST news271941311 Researchers at the University of Liverpool have found that children who have experienced severe trauma are three times as likely to develop schizophrenia in later life. http://medicalxpress.com/news/2012-04-links-childhood-trauma-schizophrenia.html Psychology & Psychiatry Thu, 19 Apr 2012 10:40:02 EST news254049158 A new Cambridge-led study has examined the past 60 years of incidence data on psychotic disorders in England in the hope that the data can reveal clues about the possible social factors which appear to underpin such conditions. http://medicalxpress.com/news/2012-03-cambridge-psychotic-disorders-future.html Psychology & Psychiatry Fri, 23 Mar 2012 09:49:01 EST news251714932 Recent research has found striking links between psychotic disorders such as schizophrenia and certain types of international immigration. Now for the first time, a major study has found that immigrating in early childhood appears to carry the highest risk. The study, conducted in the Netherlands, found that the younger the age at migration, the higher the risk of psychotic disorders. Those who immigrated when under the age of five had a twofold higher risk than those who immigrated at age 10-14 years, and a threefold higher risk than those who immigrated as adults. The study—the first to include data on age at migration—suggests that there may be an early window of vulnerability. http://medicalxpress.com/news/2012-01-migration-young-age-psychotic-disorders.html Psychology & Psychiatry Thu, 05 Jan 2012 09:26:00 EST news244977950 11 May 2011 - Two new research studies published in Biological Psychiatry point to progressive abnormalities in brain development that emerge as vulnerable individuals develop schizophrenia. http://medicalxpress.com/news/2011-05-brain-track-vulnerable-individuals-schizophrenia.html Psychology & Psychiatry Wed, 11 May 2011 10:31:25 EST news224328659
