The New York Times (9/1, Rabin) “Well” blog reports that a study conducted by researchers at the National Institute of Health found no evidence that omega-3 fatty acids and antioxidant supplements “stave off cognitive decline in older people.” Researchers recruited over 3,500 participants who were “randomly assigned…to take a lutein/zeaxanthin supplement, a supplement of omega-3 long-chain polyunsaturated fatty acids with docosahexaenoic acid (DHA) and eicosapentaenoic acid (EHA), both or a placebo.”

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.”

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.’”
