A recent study by Merikangas and colleagues published in the January 2011 issue of the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP) shows that only half of adolescents that are affected with severely impairing mental disorders ever receive treatment for their disorders. http://phys.org/news214572907.html Medicine & Health Tue, 18 Jan 2011 11:50:03 EST news214572907 A new wide-ranging study by the University of Otago, Wellington has shown that men with common mental disorders, such as depression or anxiety, are more likely than women with those disorders to have difficulties with social and role functioning. This is despite the common perception that women often have more problems with mental health and subsequent disabilities. http://phys.org/news211024005.html Medicine & Health Wed, 08 Dec 2010 10:00:01 EST news211024005 Schizophrenia is a mental disorder that differs between the sexes in terms of age at onset, symptomatology, response to medication, and structural brain abnormalities. Now, a new study from the University of Montreal shows that there is gender difference between men and women's mental ability – with women performing better than men. These findings, published recently in, Schizophrenia Research, have implications for the more than 300 000 affected Canadians. http://phys.org/news209301111.html Medicine & Health Thu, 18 Nov 2010 11:12:03 EST news209301111 Emotional prosperity in Europe is falling, and this troubling fact needs to be faced by the European governments. That is the conclusion from a new research report from the University of Warwick which documents cross-country evidence on psychological health and mental well-being. The study, by Andrew Oswald, professor of behavioural science at Warwick Business School, draws together the latest statistical evidence from a range of social-science, science and medical journals. The study is to be published in the December issue of the British Journal of Industrial Relations. http://phys.org/news209042944.html Other Sciences Mon, 15 Nov 2010 11:30:07 EST news209042944 Sleep disturbances increase the risk of work disability and may slow the return to work process. This is especially true in cases where work disability is due to mental disorders or musculoskeletal diseases. These results come from a recent study conducted by the Finnish Institute of Occupational Health in collaboration with the universities of Turku and London. http://phys.org/news207219439.html Medicine & Health Mon, 25 Oct 2010 09:57:36 EST news207219439 Mental disorders in children are often difficult to identify due to the myriad of changes that occur during the normal course of maturation. For the first time, researchers at the National Institute of Mental Health have reported on the prevalence data on a broad range of mental disorders in a nationally representative sample of U.S. adolescents, which show that approximately one in five children in the U.S. meet the criteria for a mental disorder severe enough to disrupt their daily lives. http://phys.org/news206188565.html Medicine & Health Wed, 13 Oct 2010 12:10:01 EST news206188565 Nearly one in 10 Americans is depressed, and one in 30 meets the criteria for major depression, with the rate higher among the unemployed or those who can't work, a study said Thursday. http://phys.org/news205085416.html Medicine & Health Thu, 30 Sep 2010 17:10:29 EST news205085416 Severe mental illness is more common among college students than it was a decade ago, with more young people arriving on campus with pre-existing conditions and a willingness to seek help for emotional distress, according to a study presented at the 118th annual convention of the American Psychological Association. The data support what college mental health professionals have noted for some time. http://phys.org/news200825708.html Medicine & Health Thu, 12 Aug 2010 11:00:01 EST news200825708 (PhysOrg.com) -- People with post-traumatic stress disorder (PTSD) will have the chance to take part in a pilot study of an internet-based education program. http://phys.org/news197292733.html Medicine & Health Fri, 02 Jul 2010 12:32:37 EST news197292733 Veterans with substance use disorders who die by suicide are more likely to use violent means (such as a firearm) rather than nonviolent means (such as a drug overdose), new research suggests. http://phys.org/news196350690.html Medicine & Health Mon, 21 Jun 2010 14:51:47 EST news196350690 Schizophrenia is a debilitating mental disorder affecting one in 100 people worldwide. Most cases aren't detected until a person starts experiencing symptoms like delusions and hallucinations as a teenager or adult. By that time, the disease has often progressed so far that it can be difficult to treat. http://phys.org/news196347851.html Medicine & Health Mon, 21 Jun 2010 14:04:23 EST news196347851 A new study from the David Geffen School of Medicine at UCLA suggests that increasing cigarette taxes could be an effective way to reduce smoking among individuals with alcohol, drug or mental disorders. http://phys.org/news194719816.html Medicine & Health Wed, 02 Jun 2010 18:10:01 EST news194719816 (AP) -- Day and night, Lee Mi-hwa's son stays on his computer, slaying dragons in his online fantasy world while his dinner and homework sit untouched. http://phys.org/news191150796.html Technology Thu, 22 Apr 2010 10:30:50 EST news191150796 Offspring of two parents with schizophrenia or bipolar disorder appear more likely to develop the same illness or another psychiatric condition than those with only one parent with psychiatric illness, according to a report in the March issue of Archives of General Psychiatry. http://phys.org/news186684960.html Medicine & Health Mon, 01 Mar 2010 17:30:13 EST news186684960 In reports of two new studies, researchers led by Johns Hopkins say they have identified the mechanisms rooted in two anatomical brain abnormalities that may explain the onset of schizophrenia and the reason symptoms don't develop until young adulthood. Both types of anatomical glitches are influenced by a gene known as DISC1, whose mutant form was first identified in a Scottish family with a strong history of schizophrenia and related mental disorders. The findings could lead to new ways to treat, prevent or modify the disorder or its symptoms. http://phys.org/news186383954.html Medicine & Health Fri, 26 Feb 2010 05:19:38 EST news186383954 (AP) -- Don't say "mental retardation" - the new term is "intellectual disability."

However, longer-term effects are less clear. Dr. Shamini Jain, from the UCLA Division of Cancer Prevention and Control Research, and Dr. Paul Mills, from the Department of Psychiatry at the University of California, and the Moores Comprehensive Cancer Center in San Diego, US, publish their review of the science behind biofield therapies online this week in Springer's International Journal of Behavioral Medicine. http://phys.org/news176046733.html Medicine & Health Thu, 29 Oct 2009 14:53:06 EST news176046733 Many pediatric and adolescent patients who received second-generation antipsychotic medications experienced significant weight gain, along with varied adverse effects on cholesterol and triglyceride levels and other metabolic measures, according to a study in the October 28 issue of JAMA. http://phys.org/news175885144.html Medicine & Health Tue, 27 Oct 2009 17:59:55 EST news175885144 (PhysOrg.com) -- Doctors should pay more attention to the link between common mental illness and obesity in patients because the two health problems are closely linked, according to researchers at the University of Adelaide. http://phys.org/news174132494.html Medicine & Health Wed, 07 Oct 2009 11:08:36 EST news174132494 August 25, 2009—Researchers working with Iraq and Afghanistan war veterans have found that post-traumatic stress disorder, the current most common mental disorder among veterans returning from service in the Middle East, is associated with an increased risk for thoughts of suicide. http://phys.org/news170422054.html Medicine & Health Tue, 25 Aug 2009 12:28:06 EST news170422054 Although depression is the mental disorder that most people associate with suicidal behavior, a new study reveals that a wide range of mental disorders increase the odds of thinking about suicide and making suicide attempts. Whereas depression is indeed one of the strongest predictors of suicidal thoughts across many different countries, it is disorders characterized by anxiety and poor impulse-control that best predict which people act on such thoughts -- especially in developing countries, says a multi-country study published in this week's open access journal PLoS Medicine. http://phys.org/news169188082.html Medicine & Health Tue, 11 Aug 2009 05:42:31 EST news169188082 Neurons communicate with each other with the help of nano-sized vesicles. Disruption of this communication process is responsible for many diseases and mental disorders like e.g. depression. Nerve signals travel from one neuron to another through vesicles - a nano-sized container loaded with neurotransmitter molecules. A vesicle fuses with the membrane surrounding a neuron, releases neurotransmitters into the surroundings that are detected by the next neuron in line. However, we still lack a more detailed understanding of how the fusion of vesicles occurs on the nano-scale. http://phys.org/news168770252.html Nanotechnology Thu, 06 Aug 2009 09:50:05 EST news168770252 Identification of criteria for the detection of prolonged grief disorder (PGD) appear able to identify bereaved persons at heightened risk for enduring distress and dysfunction, says a new study in this week's open access journal PLoS Medicine. The results support the psychometric validity of the criteria for PGD and should be included in the Diagnostic Statistical Manual of Mental Disorders, 5th Edition (DSM-V) and the International Statistical Classification of Diseases and Related Health Problems (ICD-11), say the authors. http://phys.org/news168598077.html Medicine & Health Tue, 04 Aug 2009 10:00:01 EST news168598077
