Medscape (6/9, Johnson) reports that research suggests that “the heavy, long-term use of cannabis is associated with negative changes in parts of the brain not previously implicated, and is linked to deficits in learning and memory.” Investigators “used the highly specific carbon 11-labeled (+)-4-propyl-9-hydroxynaphthoxazine radiotracer — known as [¹¹C]PHNO — to image the impact of cannabis on the brain.” The researchers “showed that heavy chronic cannabis use is associated with lower dopamine release in the associative striatum and the sensory motor striatum, regions involved in cognition.” The findings were presented at the Society of Nuclear Medicine and Molecular Imaging 2015 Annual Meeting.

Health Day (6/6, Dallas) reported that “well-intentioned parents of children with autism may think that special diets or supplements can help their child, but a” study published June 4 in the Journal of the Academy of Nutrition and Dietetics “suggests that often these efforts lead to problems.” The 368-child study revealed that such “regimens leave children still deficient in some nutrients, such as calcium,” yet can also cause youngsters “to take in excessive amounts of other nutrients, such as vitamin A, the researchers said.”

TIME (6/5, Sifferlin) reports, “Sexual violence against children is a global problem – and few receive supportive services exist for its victims,” according to research released June 5 by the CDC in its Morbidity and Mortality Weekly Report. That report, the results of which “come from Violence Against Children Surveys that were conducted between 2007 and 2013 among men and women ages 18 to 24 in Swaziland, Tanzania, Kenya, Zimbabwe, Malawi, Haiti and Cambodia,” shows that “at least 25% of females and 10% of males report experiencing a form of sexual violence as a child.”

The NPR (6/5, Silver) “Goats and Soda” blog interviews report lead author Steven Sumner, MD, MSC-GH, a “medical epidemiologist at CDC’s Division of Violence Prevention,” who said, “To me, the most striking finding was how few children were getting help.” Dr. Sumner added, “Expanding services to children both in terms of prevention services and response services is badly needed.”

Modern Healthcare (6/5, Robeznieks, Subscription Publication) reports that on June 2, by a 417-10 vote, “the US House of Representatives…approved funding to give crisis-intervention training to police on de-escalating violent confrontations with people who have behavioral-health problems and to fund ‘mental health courts’ that seek to provide psychiatric care instead of” incarceration.

The funding “will be available through block grants under the Justice and Mental Health Collaboration Program.” Meanwhile, yesterday afternoon, Rep. Tim Murphy (R-PA) reintroduced a “new version of his Helping Families in Mental Health Crisis Act,” which American Psychiatric Association president Renée Binder, MD, praised in a news release (6/5) as “strengthening enforcement of mental health parity, enhancing the psychiatric workforce, ensuring better coordination of federal resources, and improving research and treatment for persons with mental illness, including substance use disorders.”

The Kaiser Health News (6/3, Boodman) reports on “the consequences of delirium, a sudden disruption of consciousness and cognition marked by vivid hallucinations, delusions and an inability to focus that affects seven million hospitalized Americans” each year. The condition which “disproportionately affects” seniors, can also affect intensive care unit patients of any age “who are heavily sedated and on ventilators.” The cognitive effects of delirium may last for months and leave patients with post-traumatic stress disorder.

In continuing coverage, the Los Angeles Times (6/4, Kaplan) “Science Now” blog reports that adolescent “bullying may be responsible for nearly 30% of cases of depression among adults,” according to a study published June 2 in the BMJ. After following “2,668 people from early childhood through adulthood, researchers found that 13-year-olds who were frequent targets of bullies were three times more likely than their non-victimized peers to be depressed as adults.”

The CBS News (6/4, Welch, Kraft) website reports that the study “data factored out other causes of depression including mental and behavioral problems, previous bullying in childhood, and stressful life and family events, to focus on the relationship between bullying in teenage years and depression as adults.” For both genders, the study’s “results were the same.” MedPage Today (6/4, Walker) and Forbes (6/4, Walton) also cover the study.
