MedPage Today (1/28, Jeffrey) reports a study utilizing US commercial health insurance claims data found that “firearm injuries among parents were associated with increased rates of psychiatric disorder diagnoses and mental health visits in their children.” Researchers observed that “parental firearm injury was associated with 8.4 additional psychiatric diagnoses per 1,000 youths, as well as 23.1 additional mental health visits per 1,000 youths compared with controls averaged over the 12 months following the injury.” They noted the “increase was largest for trauma-related diagnoses such as post-traumatic stress disorder (PTSD), with an additional 8.5 diagnoses per 1,000 youths versus controls averaged over the year.” The study was published in The New England Journal of Medicine.Related Links:

MedPage Today (1/27, George) reports, “Higher stages of chronic traumatic encephalopathy (CTE), a disorder associated with repetitive head impacts often from contact sports like American football, were tied to increased odds of dementia, autopsy data showed.” Investigators found that “brain donors with stage IV CTE pathology and no other progressive brain disease had four times the odds of a dementia diagnosis compared with donors who had no CTE pathology (OR 4.48, 95% CI 1.97-10.90).” The data indicated that “donors with stage III CTE pathology were twice as likely to be diagnosed with dementia compared with decedents who had no pathology (OR 2.12, 95% CI 1.91-3.77).” The findings were published in Alzheimer’s & Dementia.

The New York Times (1/26, Valentino-DeVries, Hill) reports, “Mental health workers across the country are navigating how to treat problems caused or exacerbated by A.I. chatbots, according to more than 100 therapists and psychiatrists who told The New York Times about their experiences.” Many mentioned the “positive effects of the bots,” such as “helping patients understand their diagnoses,” but they also raised alarms about the conversations that “deepened their patients’ feelings of isolation or anxiety. More than 30 described cases resulting in dangerous emergencies like psychosis or suicidal thoughts. One California psychiatrist who often evaluates people in the legal system said she had seen two cases of violent crimes influenced by A.I.” To date, Times reporters “have documented more than 50 cases of psychological crises linked to chatbot conversations since last year.”

MedPage Today (1/26, George) reports, “Vaccination against herpes zoster (shingles) was tied to significantly less dementia risk, data from Canada’s network of primary care records showed.” Investigators found that “being eligible for a free live-attenuated zoster vaccine (Zostavax) was associated with reduced probability of a new dementia diagnosis by an absolute difference of 2.0 percentage points (95% CI 0.4-3.5, P=0.012) over 5.5 years.” The findings were published in Lancet Neurology.

The Washington Post (1/26, Johnson) reports a new studypublished in JAMA Network Open shows that “nearly half of the mortality gap between Black and White adults can be traced to the cumulative toll of a lifetime of stress and heightened inflammation.” Researchers “tracked the prevalence of two proteins linked to inflammation in the body and tied it to enduring discrimination and related social challenges.” They observed that “decades of stress – childhood adversity, trauma, discrimination and economic hardship – were associated with higher levels of inflammation later in life, which correlated with earlier death.” Overall, the results bolster “the body of evidence showing that chronic stress takes a biological toll that shortens lives.”
