More than 40 percent of women ages 18-59 experience sexual dysfunction, with lack of sexual interest -- hypoactive sexual desire disorder, or HSDD -- being the most commonly reported complaint, according to medical researchers.
A popular smoking cessation drug dramatically reduced the amount a heavy drinker will consume, a new Yale School of Medicine study has found. Heavy-drinking smokers in a laboratory setting were much less likely to drink after taking the drug varenicline compared to those taking a placebo, according to a study published online in the journal Biological Psychiatry.
Young men who have served in the British Armed Forces are up to three times more likely to take their own lives than their civilian counterparts, research published tomorrow (March 3) has found.
Cutting edge science has finally put to rest a 90-year-old mystery that involved nobility, revolution, murder and the long-romanticized story of a child's escape from the firing squad.
Sleep experts know that the mental clarity lost because of a few sleepless nights can often be restored with a good night's rest. Now, UT Southwestern Medical Center researchers have identified a key molecular mechanism that regulates the brain's ability to mentally compensate for sleep deprivation.
A follow-up study by researchers at Ben-Gurion University of the Negev (BGU) in Beer-Sheva has determined that the once prevalent custom of female genital mutilation (FGM) among Israel's Bedouin population in the Negev has virtually disappeared.
A new study finds the elevation in estradiol levels that occurs during pregnancy is more pronounced in pregnant women with restless legs syndrome (RLS) than in controls.
New research could help explain why some alcoholics are more severe drinkers than others.
Individual nerve cells in the front part of the brain can hold traces of memories on their own for as long as a minute and possibly longer, researchers at UT Southwestern Medical Center have found.
An abnormal pattern in an area of the brain that governs hearing may be an accurate method of diagnosing schizophrenia, according to a study by Yale researchers and collaborators. "These results seem to point to a cardinal abnormality in schizophrenia," said Godfrey Pearlson, M.D., professor of psychiatry at Yale School of Medicine, director of the Olin Neurospychiatry Research Center at the Institute of Living in Hartford, and senior author of the study published in Biological Psychiatry. "Using this imaging test, we were able to identify patients with schizophrenia with 97 percent accuracy."
Researchers in Pittsburgh have made significant progress in identifying the first susceptibility gene for clinical depression, the second leading cause of disability worldwide, providing an important step toward changing the way doctors diagnose and treat major depression that affects nearly 10 percent of the population. Research results show significant evidence for linkage of unipolar mood disorders to a specific region of chromosome 2q33-35 in women.
Researchers in Los Angeles have localized a region on chromosome 16 that is likely to contain a risk gene for Attention Deficit Hyperactivity Disorder, the most prevalent childhood-onset psychiatric disorder. The scientists say their finding suggest that the suspected risk gene may contribute as much as 30 percent of the underlying genetic cause of ADHD and may also be involved in a separate childhood onset disorder, autism.
Researchers have discovered a gene mutation that causes a condition apparently identical to Huntington's Disease, helping explain why some people with the disorder do not have a separate mutation found in most cases. The finding may help reveal why some diseases, like Huntington's, Alzheimer's and Parkinson's, destroy some brain cells while sparing others. "For all practical purposes this is Huntington's Disease, yet it's caused by a different mutation on a completely different chromosome," said Russell L. Margolis, M.D., associate professor of Psychiatry at Hopkins and director of the Johns Hopkins Laboratory of Genetic Neurobiology. "This is a rare version of an already rare disorder, but the mutation that causes it may not only help us better understand Huntington's Disease, but could boost our understanding of many other neurodegenerative disorders."
A new study aims to determine once and for all whether a link exists between obsessive-compulsive behavior and strep infections in children. The research, to be conducted by the University of Florida and the National Institutes of Mental Health, is prompted by anecdotal reports from parents with OCD kids that their children's behavior, such as compulsive hand washing, worsens when the child is ill with strep.
