Young animals treated with commonly-prescribed drugs develop behavioral abnormalities in adulthood say researchers at Georgetown University Medical Center. The drugs tested include those used to treat epilepsy, mood disorders and pain. http://www.physorg.com/news175271238.html Medicine & Health Tue, 20 Oct 2009 18:10:02 EST news175271238 Researchers say antiepilectic drug treatments administered when the brain is developing appear to trigger schizophrenia-like behavior in animal models. In humans, having a history of seizures in infancy is a significant risk factor for development of schizophrenia later in life, but it is not known whether the elevated risk is due to seizures themselves, or from side effects antiepileptic drug (AED) treatment. http://www.physorg.com/news175269483.html Medicine & Health Tue, 20 Oct 2009 15:20:02 EST news175269483 For decades, scientists have thought the faulty neural wiring that predisposes individuals to behavioral disorders like autism and psychiatric diseases like schizophrenia must occur during development. Even so, no one has ever shown that a risk gene for the disease actually disrupts brain development. http://www.physorg.com/news174908711.html Medicine & Health Fri, 16 Oct 2009 11:20:03 EST news174908711 (PhysOrg.com) -- Sufferers of schizophrenia and bipolar disorder are being brought together in a major new study to determine the diseases? common genetic causes. http://www.physorg.com/news174906706.html Medicine & Health Fri, 16 Oct 2009 10:13:40 EST news174906706 International study led by Sydney researchers shows homicides of strangers by people with schizophrenia are exceptionally rare and unpredictable events http://www.physorg.com/news174545378.html Medicine & Health Mon, 12 Oct 2009 06:00:01 EST news174545378 In this week's PLoS Medicine, a team of researchers from Australia and the US, led by Louisa Degenhardt at the University of New South Wales, Sydney, makes the case for estimating the role that cannabis has worldwide as a risk factor for psychosis. http://www.physorg.com/news173420594.html Medicine & Health Tue, 29 Sep 2009 05:50:03 EST news173420594 (PhysOrg.com) -- Researchers conducted a study at 9 sites in the U.S. with 375 people suffering from major depression.

Importantly, the study also finds that the risk of violence from patients with psychoses who also have substance use disorder is no greater than those who have a substance use disorder but who do not have a psychotic illness - in other words, schizophrenia and other psychotic illnesses do not appear to be responsible for any additional risk of violence above the increased risk associated with substance abuse. http://www.physorg.com/news169188298.html Medicine & Health Tue, 11 Aug 2009 06:30:03 EST news169188298 The number of people killed by individuals suffering from mental illness in England and Wales increased between 1997 and 2005, figures released today show. The rise occurred in people who were not under mental health care and was not found in mental health patients. http://www.physorg.com/news168030377.html Medicine & Health Tue, 28 Jul 2009 20:06:44 EST news168030377 (AP) -- She was sociable and happy in high school.

The effects of each of these genetic changes, innocuous on its own, add up to a significant risk for developing both schizophrenia and bipolar disorder. http://www.physorg.com/news165674543.html Medicine & Health Wed, 01 Jul 2009 13:42:44 EST news165674543 Research co-led by an academic at the University of Hertfordshire, concludes that Cognitive Behavioural Therapy (CBT) is of no value in schizophrenia and has limited effect on depression. http://www.physorg.com/news165230967.html Medicine & Health Fri, 26 Jun 2009 10:29:48 EST news165230967 Schizophrenia, a chronic and debilitating disorder marked in part by auditory hallucinations and paranoia, can strike in late adolescence or early adulthood at a time when people are ready to stand on their own two feet as fully independent adults. http://www.physorg.com/news164894857.html Medicine & Health Mon, 22 Jun 2009 13:08:52 EST news164894857 People with schizophrenia die from cancer four times as often as people in the general population. That was the conclusion of a new study published in the August 1, 2009 issue of Cancer, a peer-reviewed journal of the American Cancer Society. The study's results suggest that extra efforts should be made to improve cancer prevention and early detection in patients with schizophrenia. http://www.physorg.com/news164878421.html Medicine & Health Mon, 22 Jun 2009 08:35:10 EST news164878421 Researchers have been seeking a safe and effective way to treat cognitive impairments associated with schizophrenia by enhancing N-methyl-D-aspartate (NMDA) glutamate receptors. Functional deficits in NMDA receptors may contribute to the underlying neurobiology of this disorder. The first generation of studies trying to stimulate NMDA receptors administered large amounts of substances, like glycine or D-serine, which indirectly enhance NMDA receptor function. While there were some positive reports of efficacy, findings across studies were more inconsistent than was hoped. http://www.physorg.com/news163738759.html Medicine & Health Tue, 09 Jun 2009 03:59:38 EST news163738759 In the debate surrounding violent crimes referred to as "acts of madness" or the like, it is often assumed that the violence is a direct result of the perpetrator's mental illness. Previous research suggests that people with schizophrenia, a major psychotic disorder, are at higher risk for violent behaviour. However, there has been some uncertainty as to the magnitude of this risk increase and if it can really be attributed to the violence itself or to other factors. http://www.physorg.com/news162047519.html Medicine & Health Wed, 20 May 2009 14:12:17 EST news162047519 Significant and widespread cognitive problems appear to exist in schizophrenia in its earliest phase, making it very hard for people with the disorder to work, study or be social, according to a new study published by the American Psychological Association. http://www.physorg.com/news161443154.html Medicine & Health Wed, 13 May 2009 14:20:16 EST news161443154 A study on schizophrenia has implicated machinery that maintains the flow of potassium in cells and revealed a potential molecular target for new treatments. Expression of a previously unknown form of a key such potassium channel was found to be 2.5 fold higher than normal in the brain memory hub of people with the chronic mental illness and linked to a hotspot of genetic variation. http://www.physorg.com/news160820661.html Medicine & Health Wed, 06 May 2009 09:24:56 EST news160820661 The Medical College of Georgia is part of a large national study examining the genes of 10,000 patients with schizophrenia and 10,000 healthy individuals in an effort to pinpoint variations that can improve disease diagnosis and treatment. http://www.physorg.com/news160056481.html Medicine & Health Mon, 27 Apr 2009 13:08:36 EST news160056481 (PhysOrg.com) -- Rutgers geneticist Linda Brzustowicz and her colleagues have identified a specific DNA change that is likely to increase risk for developing schizophrenia in some people. It provides a potential mechanism that may be a point of entry for drug therapy, consistent with the growing trend of personalized medicine. http://www.physorg.com/news158321225.html Medicine & Health Tue, 07 Apr 2009 11:07:26 EST news158321225 Patients with schizophrenia are able to correctly see through an illusion known as the 'hollow mask' illusion, probably because their brain disconnects 'what the eyes see' from what 'the brain thinks it is seeing', according to a joint UK and German study published in the journal NeuroImage. The findings shed light on why cannabis users may also be less deceived by the illusion whilst on the drug. http://www.physorg.com/news158233171.html Medicine & Health Mon, 06 Apr 2009 10:40:41 EST news158233171 (PhysOrg.com) -- Scientists have revealed the role of one type of brain cell in the development of a process crucial for memory and learning. http://www.physorg.com/news157910233.html Medicine & Health Thu, 02 Apr 2009 16:59:20 EST news157910233 Researchers at the Institute of Psychiatry, King's College London have published new research which indicates that women with severe mental illness are more likely to have been abused in childhood that the general population.
