The Milwaukee Journal Sentinel (8/29, Boulton) reported that a study conducted at the University of Wisconsin-Madison “has added to the mounting evidence that growing up in severe poverty affects the way children’s brains develop, potentially putting them at a lifelong disadvantage.” The study, published recently in JAMA Pediatrics, “found that the parts of the brain tied to academic performance were 8% to 10% smaller for children who grow up in very poor households.” The study drew from 823 MRI scans “of 389 children, ages 4 to 22, from a National Institutes of Health study done to show normal brain development.”

The AP (8/29, Cox) reported that veterans with post-traumatic stress disorder are praising neuropsychologist George Lindenfeld’s Bio-Acoustical Utilization Device (BAUD), which is “approved by the Food and Drug Administration as a Class II biofeedback device.”

HealthDay (8/29, Preidt) reported, “Women in the US military are no more likely than men to develop post-traumatic stress disorder (PTSD),” according to a study published in the September issue of the Journal of Psychiatric Research. For the study, researchers “included more than 2,300 pairs of women and men who were matched on similarities – including combat experience – and followed for an average of seven years.” Investigators found that by “the end of the study, 6.7 percent of women and 6.1 percent of men had developed PTSD, a difference that is not statistically significant.”

Medscape (8/31, Harrison) reports that “updated findings from the Prolonging Remission in Depressed Elderly (PRIDE) study,” which involves “approximately 240 patients…173 of whom have completed” the first phase, “continue to support the use of right unilateral electrode placement and ultrabrief pulse stimuli as an optimal means of achieving a rapid response, and even remittance, within a week of delivering three courses of electroconvulsive therapy (ECT) in geriatric patients with major unipolar depression.” The study results were presented at the European College of Neuropsychopharmacology Congress.

HealthDay (8/30, Preidt) reported, “Risky behaviors such as reckless driving or sudden promiscuity, or nervous behaviors such as agitation, hand-wringing or pacing, can be signs that suicide risk may be high in depressed people,” research presented at the European College of Neuropsychopharmacology’s Congress suggests. The study, which involved some 2,800 people with depression, also revealed that “other warning signs may include doing things on impulse with little thought about the consequences.” People with depression “with any of these symptoms are at least 50 percent more likely to attempt suicide, the new study found.” BBC News (8/31) also covers the story.

The Los Angeles Times (8/28, Healy) reported in “Science Now” that “by the time they were 18, Britons who self-identified as ‘goth’ at the age of 15 were three times more likely to be clinically depressed and five times more likely to cut, burn or intentionally inflict injury on themselves than were young people who did not identify with goth subculture,” according to a study published online Aug. 27 in The Lancet Psychiatry.

TIME (8/29, Bajekal) reported that the study “was based on surveys of 3,694 British teens, who were asked to identify with a variety of subcultures.”

In an op-ed in the New York Times (8/28, Tufekci, Subscription Publication), contributing opinion writer Zeynep Tufekci argues that the media should change the way it covers mass shootings to decrease the likelihood of copycats. Citing an FBI study, Tufekci says that would-be shooters often seek inspiration from past attacks.

The media can limit the flow of inspiration, Tufekci says, by voluntarily monitoring what information is disseminated. What’s more, “psychiatrists agree with the FBI’s conclusion and statistical studies.”

Eight years ago after the shootings at Virginia Tech, “the American Psychiatric Association weighed in, saying that ‘the scientific evidence in this area is clear.’” Specifically, the “APA said that publicizing these materials ‘seriously jeopardizes the public’s safety by potentially inciting ‘copycat’ suicides, homicides and other incidents.’”

HealthDay (8/27, Preidt) reports that investigators “say emotional turmoil is common for women whose mammogram falsely suggests they have breast cancer.” The study, which included “nearly 400 such cases found that 88 percent of the women said they felt a sense of dejection, such as being uneasy, sad or unable to cope; 83 percent reported anxiety; 67 percent said they had behavioral changes, such as trouble dealing with spare time or work; and 53 percent suffered sleeping problems.” The findings were published in Cancer Epidemiology, Biomarkers & Prevention.

NBC News (8/27, Fox) reports on two studies published in JAMA Psychiatry that examine the effect of marijuana on the brain. In the first study, “David Pagliaccio, formerly of Washington University in St. Louis and now at the National Institute of Mental Health, and colleagues” compared the brains of marijuana users to non-users.

The results seemed to suggest that marijuana users “had some shrinkage in two brain regions called the amygdala and the right ventral striatum,” but when researchers compared marijuana users to their siblings, “the differences disappeared.” Meanwhile, a second study “found that marijuana appears to change the brain structure of young men with a high genetic risk of schizophrenia.” Dr. David Goldman, of the National Institute on Alcohol Abuse and Alcoholism, said the studies don’t offer a clear picture of anything, adding, “It’s probably more a story of what we don’t know than what we do know.”

According to HealthDay (8/27, Thompson), Dr. Goldman wrote, “The burden of cannabis’ effects may fall more heavily on people who, because of genetic makeup or early life exposures, are at greatest risk for brain structural changes, psychosis or addiction.” He added “It is safer not to expose people to psychoactive drugs.”

Reuters (UK) (8/26, Doyle) reports that a research letter published online Aug. 25 in the Journal of the American Medical Association suggests that US combat veterans who have seen action in Afghanistan and Iraq and who were separated from military service because of misconduct appear to have an increased likelihood of being homeless.

Researchers arrived at this conclusion after analyzing data on some 448,290 separations from the military of active-duty service members who were deployed in Iraq or Afghanistan and went on later to avail themselves of services offered by the Veterans Health Administration. An expert who had no involvement in the study pointed out that mental health disorders may play both a role in why such veterans were discharged for misconduct and why they are homeless.
