HealthDay (4/21, Preidt) reported, “Half-siblings of children with autism are at increased risk for the disorder, according to a recent study” published in Molecular Psychiatry “that provides new genetic clues about autism.” Investigators looked at, among other things, data from “more than 5,000 US families enrolled in a nationwide autism registry.” Researchers “found autism had been diagnosed in 10 percent to 11 percent of full siblings and five…to seven percent of half-siblings.”

The Los Angeles Times (4/20, Healy) “Booster Shots” blog reports that a study published online April 19 in Science Magazine suggests that the way in which people deal with deal with regret may make a significant difference in whether they can be healthy and happy in old age. Researchers found that older adults who had experienced late-life depression were more likely to respond to regret with a pounding heart rate and moist hands, much as a healthy young person would respond. In contrast, healthy older adults would respond to regret with serenity. The blog post adds that among 40 older subjects over the age of 50, “whenever regret was evident, the anterior cingulate cortex — a key hub for communication between emotions and rational decision-making — came alive in the happy older adults,” as revealed by functional magnetic resonance imaging scans.

According to HealthDay (4/20, Marcus), Murali Doraiswamy, MD, of the Duke School of Medicine, who was not involved in the study, pointed out that “the brain patterns seen in depressed participants, if confirmed in larger studies, could potentially help identify people who are vulnerable to late-life depression and in need of counseling.”

The Department of Veterans Affairs receives extensive, mostly positive coverage of its Thursday announcement that it will hire 1,900 more mental-health professionals.

The AP (4/20, Tucker) reports that VA “said Thursday it was increasing its staff of mental health workers by roughly 1,900, part of an effort to address a shortage of specialists and to better prepare for the medical needs of veterans returning home from war.” The last point was emphasized in a statement about the new hires from VA Secretary Eric Shinseki. The “move was cheered by Iraq and Afghanistan Veterans of America, which also called on the VA to reduce its claims backlog and urged President Barack Obama to issue a national call for service for mental-health professionals.” The House Veterans Affairs Committee chairman, US Rep. Jeff Miller (R-FL), “said the announcement was a good start, but that the VA also needs to strengthen training of employees who encounter veterans suffering from post-traumatic stress disorder.”

The hiring…would increase the department’s mental health staff by nearly 10 percent at a time when the veterans health system is being overwhelmed not just by veterans returning from Iraq and Afghanistan, but also by aging veterans from the Vietnam era.” The Times notes that VA’s “announcement comes as the department is facing intensified criticism for delays in providing psychological services to veterans at some of its major medical centers.”

A 2010 report by the Drug Abuse Warning Network said drugs used for pain relief, anxiety or insomnia were involved in almost a quarter of adverse drug reactions among older adults.” One specialist said that “for about 80 percent of the population, prescribing these drugs is the right thing to do,” but “for about 20 to 25 percent…there is a risk of developing a dependency.”
