HealthDay (12/1, Mundell) reported that having a “naturally sunny disposition” may “protect you from dementia as the years advance…research shows.” According to a team at Northwestern University in Chicago, “certain personality traits – being conscientious, outgoing and positive – appear to lower a person’s odds for a dementia diagnosis.” Meanwhile, “being neurotic and more negative in outlook and behavior was tied to a higher risk for mental decline.”

The findings were published in Alzheimer’s & Dementia.

HealthDay (12/1, Mundell) reported research from Johns Hopkins University in Baltimore found that “participating in repeated collision sports like football may have a direct link to long-term inflammation in the brain.” Additionally, “football players … performed notably worse than swimmers on tests that tracked learning and memory skills.” The researchers “examined PET and MRI brain scans of 27 former NFL players, taken between 2018 and early 2023.” The findings were published in JAMA Network Open.

mHealth Intelligence (12/1, Vaidya) reported that “while telehealth use has dropped nearly 25 percentage points from peak usage in 2020, certain specialties, like mental health, infectious disease, and obstetrics, still have higher-than-average telehealth use, according to new data” from Epic Research.

Usage of telehealth “skyrocketed during the initial peak early in the pandemic but has since declined, though usage remains higher than pre-pandemic levels.” The data show “telehealth use encompassed less than 1 percent of all visits in the last three quarters of 2019,” but that “figure jumped to 31.2 percent in Q2 2020 before dropping to 5.8 percent in Q3 2023.”

Psychiatric News (12/1) reported “alcohol intoxication is associated with an increased risk of suicide death by firearms compared with other methods, especially among males and among young and middle-aged females, a study” suggests. The study found “young and middle-aged females who were intoxicated at the time of death had a 31% and 34% greater risk of using a firearm compared with their non-intoxicated peers, respectively.”

Meanwhile, “young, middle-aged, and older intoxicated males had a 28%, 17%, and 4% increased risk of using a firearm compared with their non-intoxicated peers, respectively.” The findings were published in the American Journal of Preventive Medicine.

The New York Times (11/30, Barry) reports that a group of researchers at Yale University and the Icahn School of Medicine at Mount Sinai “conducted brain scans of 28 people with PTSD” in an attempt to find empirical evidence that “traumatic memories function differently from other memories.”

The scans “found clear differences, the researchers reported,” demonstrating that people listening to sad memories “showed consistently high engagement of the hippocampus.” However, when “the same people listened to their traumatic memories … the hippocampus was not involved.” The findings were published in Nature.
