Barack Obama pushes end to mental health stigma; Bradley Cooper joins efforts President Barack Obama said it is time to bring mental health "out of the shadows." Mr Obama is hosting a mental health conference as part of his response to the Sandy Hook school shootings. US President Barack Obama has called for a more robust discussion on mental illness, saying the time had come to bring the issue "out of the shadows." Speaking at the opening session of a White House conference on mental health, Mr Obama said his goal was to let people affected by these issues know they should not suffer in silence. "Struggling with a mental illness or caring for someone who does can be isolating," Mr Obama said. It begins to feel as if, not only are you alone, but that you shouldn't burden others with the challenge. The conference is part of Mr Obama's response to last year's shooting massacre at Sandy Hook elementary school in Newtown,Connecticut. While the president emphasised that most people with mental health problems are not violent, he said untreated mental illness can lead to larger tragedies. There's been little publicly revealed about the mental health of Sandy Hook shooter Adam Lanza, although it's been documented that other gunmen involved in mass shootings suffered from mental illness. Federal law bans certain mentally ill people from purchasing firearms, but the background check system is woefully incomplete and Mr Obama is trying to get more mental health records included. "We can do something about stories like this," he said. In many cases, treatment is available and effective. Top administration officials, along with actors Bradley Cooper and Glenn Close, were among those participating in the White House conference. Actor Bradley Cooper arrives at the White House conference. Cooper, who played a bipolar man in Silver Linings Playbook, now works to build mental health awareness. The agenda includes discussion of insurance coverage for mental health care and substance abuse, recognising the signs of mental illness in young people and improved access to services for veterans. The overall goal is reducing the stigma of mental health problems and encouraging those who are struggling to get help. US Vice President Joe Biden, the president's point man on gun violence, is scheduled to close it from the Eisenhower Executive Office Building. Around 150 invited attendees include mental health advocates and patients, educators, health care providers, faith leaders, lawmakers and local government officials from across the country. Cooper and Close bring their advocacy and a celebrity buzz to the event. Cooper has been promoting mental health awareness since his Oscar-nominated leading role as a man with bipolar disorder in last year's Silver Linings Playbook, and plans to help Mr Biden and Veterans Affairs Secretary Eric Shinseki close the conference. Close said Monday that her experience is "a family affair." Her sister, Jessie, was diagnosed with bipolar disorder at 51 and Jessie's son, Calen, was diagnosed with schizoaffective disorder at 19. In 2009, Close's family battles led her to help start a non-profit called Bring Change 2 Mind, which produces public service announcements to fight the stigma and discrimination associated with mental illness. She is listed on a panel discussion on how to address negative attitudes about mental illness. What's important is social inclusion. There's a lot of stigma," Close said in an interview Monday morning with MSNBC from the White House briefing room. She said her nephew feels his brain is healing and that he's "living a full and wonderful life." Close said her sister is doing well, "but what it would have meant to her if she had early diagnosis." Actor Glenn Close started a nonprofit to fight the stigma of mental illness after her sister was diagnosed with bipolar and her nephew with schizoaffective disorder. We need people living with mental illness with the courage to say this is what I am living with. I can talk about this," Close said. The conference comes after Mr Obama's defeat on gun control legislation. Unable to get Congress to approve background checks, an assault weapons ban and other limits on firearms, the president has vowed to do what he can through executive action. Among 23 executive orders Mr Obama signed in response to the Sandy Hook shooting, which killed 26, was a directive that Health and Human Services Secretary Kathleen Sebelius and Education Secretary Arne Duncan launch a national dialogue on mental health. The conference is part of that, with Ms Sebelius hosting the panel on addressing negative attitudes and Mr Duncan moderating a session on successful mental health outreach efforts. In announcing the conference, the White House stressed that the vast majority of people with mental health conditions are not violent and are more likely to be victims than perpetrators of crimes. But the need to improve the country's mental health care system is something all sides of the gun debate have advocated, including the National Rifle Association. "That is something substantive that Congress and the president could do right now that would actually help prevent future tragedies, unlike the gun control proposals that the president unsuccessfully tried to push through Congress," said NRA spokesman Andrew Arulanandam Mr Obama announced that the Department of Veterans Affairs will conduct mental health summits nationwide to increase awareness of VA programs and link veterans and their families with community resources to support their needs. The conference also plans to tout improvements in mental health coverage under Mr Obama's health care law, including a ban beginning next year against denying coverage to those who are mentally ill. The White House also plans to focus on commitments being made in the private sector to increase understanding and awareness, including a campaign by the National Association of Broadcasters through television and radio ads and social media. Several organisations that work with young people also are planning to make new commitments, including high school principals holding mental health assemblies, to YMCA instructing staff and camp counselors to recognise the signs of mental health issues in kids, to religious leaders launching conversations on the issue.
