USA Today (7/27, Weintraub) reports several new studies presented at the Alzheimer’s Association International Conference in Toronto confirmed that “living a healthy, non-smoking, socially active and interesting life remains the best way to prevent dementia.” Moreover, research shows there are currently no “medications that can prevent the fatal disease, or extend the lives of the more than 5 million Americans currently suffering from Alzheimer’s.”

The Guardian (UK) (7/27, Boseley) reports, “People living in affluent countries are more likely to suffer from post-traumatic stress disorder than those in poorer nations,” researchers found. The large study revealed that “Canada has the highest levels of PTSD, followed by the Netherlands, Australia, the US and New Zealand,” while “the lowest levels were found in Nigeria, China and Romania.” The findings were published in the July issue of the British Journal of Psychiatry.

HealthDay (7/27, Preidt) reports, “Changes that occur in teens’ brains as they mature may help explain why the first signs of mental illness tend to appear during this time,” a magnetic resonance imaging scan study suggests. Investigators found not only that the “cortex becomes thinner” as adolescents grow older, but also that “the brain regions that undergo the greatest changes during the teen years are also where genes associated with schizophrenia risk are most strongly expressed.” The findings of the nearly 300-participant study were published July 25 in the Proceedings of the National Academy of Science.

The New York Times (7/26, A9, Belluck, Subscription Publication) reports, “The World Health Organization is moving toward declassifying transgender identity as a mental disorder in its global list of medical conditions.” This comes as “a new study lend[s] additional support to a proposal that would delete the decades-old designation.”

The Times adds that “in the fifth and most recent edition,” the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, “the designation was changed to ‘gender dysphoria,’ and was defined to apply to only those transgender people who are experiencing distress or dysfunction, said” psychiatrist Jack Drescher, MD, a “psychoanalyst at New York Medical College, who serves on the WHO working group and served on a similar working group for the DSM-5.”

The Washington Post (7/27, Love) reports a new study indicates a type of computer game “could decrease the risk of symptoms of dementia by almost half, compared to not having any brain training at all.” The findings are still being reviewed, so they are considered preliminary.

This type of game is known as “a speed-of-processing task,” which is “one of three types of cognitive training that 2800 people took part in during The Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study, a randomized longitudinal study funded by NIH” in 2014.

The Post adds that “even with this compelling ACTIVE data analysis, researchers are hesitant to accept the findings right away,” because “the 2014 ACTIVE study wasn’t designed to track dementia, Jonathan King” said. King “was the project director and co-author of the 2014 study and is a program director at the National Institute on Aging.”

The ABC News (7/26, Mohan-Sivasankar) website reports that “men with Alzheimer’s” may have “atypical symptoms” and may be “younger at diagnosis,” research suggests. What’s more, physicians “may be able to screen men for Alzheimer’s at even younger ages,” investigators posit. The findings of the 1,606-brain study were presented July 26 at the Alzheimer’s Association International Conference 2016.

In “Social Issues,” the Washington Post (7/26, Bahrampour) reports that the study “also found that the disease attacks different areas of the brain in men and women.” In males, Alzheimer’s “spreads more quickly and more commonly attacks the cortex, which is responsible for behavior, language, and motor skills,” whereas in females, “the spread is slower and the disease more typically attacks the hippocampus, leading to memory problems.”

HealthDay (7/25, Preidt) reports, “People with bipolar disorder [BD] may face a long wait from when their symptoms start to the time they get a proper diagnosis,” research indicates. On average, the delay “is six years.” The findings of the 27-study meta-analysis encompassing some 9,400 patients were published July 25 in the Canadian Journal of Psychiatry.

HealthDay (7/25, Bernstein) reports, “Teenage athletes are less likely to abuse prescription” pain medications “than kids who don’t play sports or exercise,” research published online July 25 in Pediatrics suggests. The study’s findings “run counter to some research in recent years detailing concerns about injured teen athletes abusing opioid” pain medications prescribed by physicians “and then moving on to use heroin.”

MedPage Today (7/25, Walker) reports that in arriving at the study’s conclusions, investigators “examined data from 191,660 respondents – 52% eighth graders and 48% tenth graders.”

The Washington Times (7/25, Ernst) reports, “A survey by the George W. Bush Institute’s Military Service Initiative” of about 1,000 US adults suggests that “Americans have a warped understanding of veterans’ mental health issues.” The survey found that approximately “40 percent of adults in the US, Canada and the United Kingdom hold the erroneous belief that more than half of 2.8 million post-9/11 veterans have psychological problems.” Estimates made by the Rand Corporation, however, found that “10 and 20 percent of veterans struggle with mental health issues.”

In “Social Issues,” the Washington Post (7/24, Bahrampour) reported, “Work that involves complex thinking and interaction with other people seems to help protect against the onset of Alzheimer’s,” research indicated.

One study revealed that “while a ‘Western’ diet (characterized by red and processed meats, white bread, potatoes, pre-packaged foods, and sweets) is associated with cognitive decline, people who ate such food could offset the negative effects and experienced less cognitive decline if they also had a mentally stimulating lifestyle.”

A second study, which involved brain scans, revealed that “people with increased white matter hyperintensities (WMHs) – white spots that appear on brain scans and are commonly associated with Alzheimer’s and cognitive decline – were able to better tolerate WMH-related damage if they worked primarily with other people rather than with things or data.”
