CNN (11/3, LaMotte) reports, “Increasing the number of steps” taken “every day may slow cognitive decline in older adults who already have biological signs of early Alzheimer’s disease, according to a new observational study.”

MedPage Today (11/3, George) reports that investigators found that “in a group of cognitively unimpaired older adults with elevated levels of amyloid-beta, Alzheimer’s-related decline was delayed by an estimated 3 years on average for those who walked 3,000-5,000 steps per day, and by 7 years in people who walked 5,000-7,500 steps per day.” The “relationship emerged only for people with elevated brain amyloid,” and “was not related to lower amyloid burden at baseline or over time.” MedPage Today adds, “Instead, higher physical activity was associated with slower amyloid-related inferior temporal tau accumulation, which mediated associations with slower cognitive decline.” The study was published in Nature Medicine.

Healio (11/3, Herpen) reports a study found that “shorter total time in bed during school days and more frequent night awakenings were associated with an elevated suicide risk in U.K. adolescents.” Study participants aged 14 to 17 years “were tasked with reporting their sleep behaviors at age 14 based on six categories developed” by the Millennium Cohort Study: “bedtimes and wake times on both school and non-school days, 4-week sleep initiation intervals and 4-week frequency of nighttime awakenings.” Study results indicated that “shorter total time spent in bed on school days and more frequent night awakenings were significant predictors for suicide attempt at age 17.” The researchers “further reported that, with the frequency of awakenings acting as a predictor, rational decision-making moderated the association between night awakenings and suicide attempts.” The study was published in Sleep Advances.

ABC News (11/1, Gomez) reported that millions of Americans “are discovering just how much their plans will cost as open enrollment for Affordable Care Act insurance plans began on Nov. 1.” An analysis from KFF “found that if the enhanced premium tax credits expire, as they are currently set to do on Dec. 31, ACA enrollees will see their monthly premiums more than double – rising by roughly 114% on average. An estimated 22 million out of 24 million ACA marketplace enrollees are currently receiving a tax credit to lower their monthly premiums. Even if those credits are extended, KFF found that the amount insurers charge for ACA premiums will rise by an average 26% in 2026.”

Reuters (11/1, Niasse, Layne, Sullivan) reported that the “likelihood that enrollment will be unaffected by the fight over subsidies – whether they are extended or not – is slim. Subsidized enrollees are expected to see an average premium increase to $1,904 a year from $888 in 2025, KFF said.”

The Hill (10/31, Coakley) reported a study published in Tobacco Control suggests that “teens and young adults who use cannabis may be significantly more likely to become regular tobacco users later on.” According to the study, “cannabis use among youth may be responsible for roughly 13% of new cases of regular tobacco use in the United States.” Researchers found that “among the younger respondents, age 12 to 17, 32.7 percent of those who used cannabis had become regular tobacco users by 2021, about 15 percentage points higher than their peers who did not use cannabis. For young adults, age 18 to 24, the difference was smaller but still notable, with 14 percent of cannabis users becoming regular tobacco users.” The Hill added, “When weighed on a national level, researchers estimate that more than 500,000 fewer young Americans might have avoided regular tobacco use if they had not previously used cannabis.”

Psychiatric News (10/31) reported a study found “patients with mental illness who received a model of Assertive Community Treatment (ACT) that integrates local police into ACT teams (ACT-PI) had significantly fewer overall police encounters than before their entry into treatment.” The overall “rates of monthly police interactions decreased significantly for individuals after admission to the ACT-PI program, from an average of one occurrence every two months to one occurrence every three months.” In addition, “clients with a history of violence showed a decrease in violent occurrences and an increase in mental health–focused interactions with police.” According to researchers, this finding “suggests that ACT-PI program admission might reduce the risk of violent behaviors that can put staff and the public in danger while facilitating police interactions that focus on mental health.” The study was published in Psychiatric Services.
