“We found that the young people who had a parent or sibling with bipolar disorder had reduced brain responses to emotive faces, particularly a fearful face<\/strong>. This is an extremely promising breakthrough,” says study leader UNSW Professor Philip Mitchell.<\/p>\n “We know that bipolar is primarily a biological illness with a strong genetic influence but triggers are yet to be understood. Being able to identify young people at risk will enable implementation of early intervention programs, giving them the best chance for a long and happy life<\/strong>,” says Professor Mitchell.<\/p>\n Affecting around 1 in 75 Australians, bipolar disorder involves extreme and often unpredictable fluctuations in mood. The mood swings and associated behaviours such as disinhibited behaviour, aggression and severe depression, have a significant impact on day-to-day life, careers and relationships. Bipolar has the highest suicide rate of all psychiatric disorders<\/strong>.<\/p>\n Researchers used functional MRI to visualise brain activity when participants were shown pictures of happy, fearful or calm (neutral) human faces. Results showed that those with a genetic risk of bipolar displayed significantly reduced brain activity in a specific part of the brain known to regulate emotional responses.<\/p>\n “Our results show that bipolar disorder may be linked to a dysfunction in emotional regulation and this is something we will continue to explore<\/strong>,” Professor Mitchell said.<\/p>\n “And we now have an extremely promising method of identifying children and young people at risk of bipolar disorder.”<\/p>\n “We expect that early identification will significantly improve outcomes for people that go on to develop bipolar disorder, and possibly even prevent onset in some people.”<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the University of New South Wales press release via EurekAlert!: Researchers from the University of New South Wales and Black Dog Institute in Sydney, Australia have used brain imaging… Read more »<\/a><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[5,6,9],"tags":[70,15,42,49,31,158,214],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/9228"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=9228"}],"version-history":[{"count":5,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/9228\/revisions"}],"predecessor-version":[{"id":9395,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/9228\/revisions\/9395"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=9228"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=9228"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=9228"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"mri](\"http:\/\/therapytoronto.ca\/news\/wp-content\/uploads\/2012\/10\/mri_scan.jpg\")
Researchers from the University of New South Wales and Black Dog Institute in Sydney, Australia have used brain imaging technology to show that young people with a known risk of bipolar (but as yet have no signs of the condition) have clear and quantifiable differences in brain activity<\/strong> when compared to controls.<\/p>\n
