The Washington Post (1/22, Johnson) reports, “Obesity in midlife may cause vascular dementia later in life by raising blood pressure over decades and quietly damaging brain vessels, according to new research released Thursday.” The study, published in the Journal of Clinical Endocrinology & Metabolism, found that “having a higher body mass index increases the risk of vascular dementia by roughly 50 to 60 percent.” An association between dementia and obesity “has long been the subject of study, and the new research strongly indicates there is indeed a link.”
        
ABC News (1/22, Cobern, Charles) reports the study provides “the strongest evidence to date showing a direct relationship between BMI and the increased risk of developing vascular dementia, a risk heavily influenced by elevated blood pressure.” Investigators “say these findings highlight how important reducing these risk factors are to help prevent this form of dementia and protect brain health.”

HealthDay (1/21, Thompson) reports a study found that lesbian or bisexual women “had a 38% higher likelihood of alcohol being involved in their death by suicide compared to heterosexual women,” and were “more likely to be intoxicated at the time of their death.” The researchers “analyzed data collected by the federal National Violent Death Reporting System between 2013 and 2021. The data involved nearly 219,000 people who died by suicide, including 3,425 LGB people.” The results indicated “that LGB women had a 15% higher likelihood of detectable blood alcohol content following their death by suicide. They also were 17% more likely to be intoxicated when they” died by “suicide, researchers found.” Researchers noted they “found no similar association among gay or bisexual men when it comes to alcohol and suicide.” The study was discussed in a JAMA Network Open research letter.

MedPage Today (1/21, Jeffrey) reports a survey study found that “regular use of generative artificial intelligence (AI) was associated with greater levels of depressive symptoms.” Researchers observed that “in sociodemographic-adjusted regression models, daily use of AI was associated with greater levels of depressive symptoms as measured by the 9-item Patient Health Questionnaire, as was use multiple times per day, compared with no use.” They also found that greater AI use was “associated with a higher likelihood of reporting at least moderate depressive symptoms, that clinicians would typically refer for evaluation and treatment.” The study was published in JAMA Network Open.

Psychiatric News (1/20) reports a study found there is “no significant association between the presence of a recovery residence for people with substance use disorder (SUD) and nearby property values.” The researchers used “publicly available data from census tracts in Texas” to determine that “the median home value was between $12,000 and $39,000 higher on tracts with a recovery residence compared with nearby tracts without a recovery residence, depending on the comparison method used.” Additionally, “tracts with recovery residences also had a slightly higher mean number of housing units, higher Social Vulnerability Index scores, and larger total population sizes.” With that said, the researchers noted the “study focused on Texas and may not be generalizable to other states with different housing markets or policy environments.” The study was published in Drug and Alcohol Dependence.

The New York Times (1/20, Branch) reports San Francisco’s Golden Gate Bridge “has been the site of more than 2,000 confirmed suicide leaps since its completion in 1937.” Starting in 2018, workers began assembling “a complicated, miles-long series of stainless-steel nets” on both sides of the bridge to act as a “suicide deterrent system.” In 2024, “as the final pieces of the net were installed and tweaks were made, there were eight. In 2025, the first full year with the nets in place, there were four, and none between June and December. That annual total is surely among the fewest ever recorded at the bridge, and seven months might be the longest stretch without a suicide at the bridge, though early records are sparse.”
