CHICAGO, Dec 03, 2008 /PRNewswire-USNewswire via COMTEX/ -- Researchers using functional MRI (fMRI) have determined that the circuitry in the area of the brain responsible for suppressing memory is dysfunctional in patients suffering from stress-related psychiatric disorders. Results of the study will be presented today at the annual meeting of the Radiological Society of North America (RSNA).
In the last few years, working from home has gone from being a rarity to a reality.
With advances in technology, more people are able to link to work from their home computers or laptops. And as employees continue to crave flexibility and yearn for a better work/life balance, more people are working from home for at least part of their workweek.
Adults with primary insomnia have a specific neurochemical imbalance that makes it more difficult for their brains to settle down for sleep, a new study says.
People with primary insomnia for more than six months have 30 percent less gamma-aminobutyric acid (GABA), a chemical that slows overall activity in many brain areas, according to the report in the Nov. 1 issue ofSleep. A "racing mind" and an inability to shut down at night is a common complaint of people with primary insomnia.
Can scientists predict who will develop anxiety disorders years in advance? UCLA psychology professor Michelle Craske thinks so. She is four years into an eight-year study evaluating 650 students, who were 16 when the study began, to identify risk factors for the development of anxiety and depression -- the most comprehensive study of its kind.
According to the National Institute of Mental Health (NIMH), about six million American men suffer from depression every year. Yet psychologists know that men are far less likely than women to seek help not only for all mental-health problems, but depression in particular.
According to the NIMH public-information campaign, "Real Men. Real Depression.," which began in 2003, men may be unlikely to admit to depressive symptoms and seek help.
Finnish scientists have identified genes that may predispose to anxiety disorders. Research conducted under the supervision of Academy Research Fellow Iiris Hovatta have focused on genes that influence human behaviour, and some of the studied genes show a statistical association with specific anxiety disorders.
There are plenty of people who coast across the Chesapeake Bay Bridge without even a flicker of anxiety, never giving a thought to any greater calamity than whether they forgot the sunscreen or made an error in judgment in packing the Speedo.
But for some people, the 4.3-mile span sparks feelings from mild consternation to outright panic. What if the bridge sways or collapses? What if an erratic driver forces them out of their lane and into the drink? Or worse still, what if they completely freak out and in a state of panic accidentally drive themselves into the bay?

The longer Philadelphia Eagles guard Shawn Andrews was missing from training camp, the more suspicious some fans grew as to the reasons why.
He's probably on drugs, some diehards speculated in the blogosphere. He's holding out for more money, others wrote on the Philadelphia newspapers Web pages. He's fat, lazy and just doesn't want to get hurt in football contact drills, still others opined.
Smiling, dancing and spending less money are just some of the ways to feel happier according to a government scientific adviser.

Dr. Daniel Pine, a psychiatrist, directs the research program on mood and anxiety disorders of children and adolescents at the National Institute of Mental Health in Bethesda, Md. The research seeks to identify the genetic and environmental factors underlying these mental illnesses so clinicians can identify who might be prone to them, spot early symptoms and tailor treatments more precisely to individual patients.

Q: What is the difference between an anxiety disorder and anxiety that is an appropriate response to an uncomfortable or threatening situation?
ScienceDaily (May 20, 2008) -- Religious leaders have contended for millennia that burning incense is good for the soul. Now, biologists have learned that it is good for our brains too. An international team of scientists, including researchers from Johns Hopkins University and the Hebrew University in Jerusalem, describe how burning frankincense (resin from the Boswellia plant) activates poorly understood ion channels in the brain to alleviate anxiety or depression. This suggests that an entirely new class of depression and anxiety drugs might be right under our noses.
TUESDAY, June 17 (HealthDay News) -- The relationship between diabetes and depression apparently cuts both ways: Not only are people with treated type 2 diabetes at a heightened risk for developing depression, individuals with depression are also at risk for developing diabetes.
NEW YORK (Reuters Health) - Obesity is a well known risk factor for certain physical health problems, but a new study suggests that heavy adults also have higher rates of psychiatric disorders.
ScienceDaily (May 12, 2008) -- Using single-photon emission computed tomography (SPECT), researchers in The Netherlands were able to detect biochemical differences in the brains of individuals with generalized social anxiety disorder (also known as social phobia), providing evidence of a long-suspected biological cause for the dysfunction.
Social anxiety disorder prevents some 15 million Americans from leading normal social and romantic lives, a new survey finds.
The disorder leaves many isolated, ashamed and often misdiagnosed. Thirty-six percent of those with social anxiety disorder have symptoms for 10 years or more before seeking help, the Anxiety Disorders Association of America reports.
People who struggle against social convention fascinate Christopher Lane, a Northwestern University professor of English. In his new book, "Shyness: How Normal Behavior Became a Sickness," (Yale University, $27.50) Mr. Lane looks at people who don't conform to our culture's fondness for sociability. It's a provocative look at an important chapter in the history of modern psychiatry.
Mr. Lane sat down with the Chicago Tribune recently to talk about the book. An edited transcript follows.
SAN DIEGO - Dr. John Kelsoe has spent his career trying to identify the biological roots of bipolar disorder. In December, he announced he had discovered several gene mutations closely tied to the disease, also known as manic depression.
The latest gene-scanning technology may have shed some much-desired light on a potential cause for schizophrenia, a mental disorder characterized by delusions and scrambled thought processes. The disease is believed to affect 1% of the population.
FRIDAY, March 14 (HealthDay News) -- Higher anxiety levels may help elderly women live longer, but may harm older men, U.S. research shows.
A team at the Cleveland Clinic and Case Western Reserve University followed 1,000 seniors in three Florida retirement communities for up to 15 years.
They found that women with higher levels of anxiety at the start of the study lived longer than others. Year-to-year changes in anxiety levels didn't appear to affect women's survival, either.
There are no pills, no invasive procedures, yet doctors say it works.
Doctors said magnets might be the key to successful treatment for those with major depression.
Doctors said that 10 to 15 percent of Americans suffer an episode of major depression at some time in their lives.
Standard treatment doesn't always work and medication can have difficult side effects. But there may be another option with minor side effects and major results.
Research suggests new-generation antidepressants are often no more effective than dummy pills.
A review has looked at four commonly-used antidepressants and the clinical trials submitted to gain licensing approval.
They included antidepressants regularly prescribed in the UK, including fluoxetine (Prozac), venlafaxine (Efexor) and paroxetine (Seroxat).
Feb. 15, 2008 -- Women who give birth to a boy may be at increased risk of getting severe postpartum depression, according to a French study.
But a Canadian expert on women's mental health says the conclusion is premature.

WASHINGTON -- The Food and Drug Administration said it is "increasingly likely" that Pfizer Inc.'s smoking-cessation drug Chantix may be tied to serious psychiatric symptoms. The FDA's comment is part of a public health advisory issued Friday.
(HealthDay News) -- Women who stop being religiously active are three times more likely to suffer generalized anxiety disorder than women who have always been religiously active, researchers report.
(WebMD) A 12-week course of talk therapy may help curb the often debilitating symptoms of panic disorder -- including intense fear, chest pain, heart palpitations, and shortness of breath.

It's no secret that men with angry, explosive personalities are at a higher risk of a heart attack. But they're not alone: Nervous, withdrawn and chronically worried people are courting coronary problems, too, according to a new long-term study in the Journal of the American College of Cardiology. Of 735 American middle-aged or elderly men who had good cardiovascular health in 1986, those who scored highest on four different scales of anxiety were far more likely to suffer heart attacks later in life. Men in the top 15% on any of the four scales, or on a combined scale of all four, had a 30% to 40% greater chance of heart attack than their less anxious peers.
