CNN (7/30, Howard ) reports “research suggests that the majority of young people who have died by suicide did not have a documented mental health diagnosis in their medical history.” About “3 out of 5 young people who died by suicide between January 2010 and December 2021 had no previously diagnosed mental health condition, according to the study,” which “suggests that mental health problems might be going missed or undiagnosed, and thus untreated, in some young people.” The findings were published in JAMA Network Open.

HealthDay (7/30, Thompson ) reports researchers came to this conclusion after analyzing “data on more than 40,000 suicides by youth ages 10 to 24 between 2010 and 2021” that had been “gathered by the U.S. Centers for Disease Control and Prevention.”

Neurology Advisor (7/29, Khaja) reports, “Traumatic brain injury (TBI) may potentially increase the risk for bipolar disorder and schizophrenia, with varying effects depending on age, sex, and severity, according to study results.” Investigators undertook “an observational study combining a population-based approach, nested case-control, and sibling comparison design to explore the link between TBI and later bipolar disorder and schizophrenia diagnoses, investigate if there is a correlation influenced by TBI severity, and assess potential moderating effects of demographic and familial factors.” The findings were published in Psychiatry Research.

HCP Live (7/29, Derman) reports, “A new study demonstrated the number of relapses among patients with alcohol use disorder (AUD) depends on whether their depression symptoms improve on antidepressants.” Using “data from the double-blind, randomized clinical trial on alcohol-specific inhibition training among patients with AUD,” researchers “analyzed 153 detoxified AUD patients who attended a 12-week residential treatment program between 2015 and 2019.” The findings were published in Alcohol, Clinical and Experimental Research.

Healio (7/26, Rhoades) reported, “Increased social isolation may be linked to greater risks for several adverse health outcomes in older adults, according to a study.” Researchers came to this conclusion after assessing “associations between changes in social isolation and multiple health outcomes – including death, CVD, dementia, stroke and disability — within a sample of 13,649 respondents aged 50 years or older from the 2006 to 2020 Health and Retirement Study waves.” The findings were published in JAMA Network Open.

The New York Times (7/28, Belluck ) says researchers on Sunday “reported that a blood test was significantly more accurate than doctors’ interpretation of cognitive tests and CT scans in signaling” Alzheimer’s disease. The study “found that about 90 percent of the time the blood test correctly identified whether patients with memory problems had Alzheimer’s,” while “dementia specialists using standard methods that did not include expensive PET scans or invasive spinal taps were accurate 73 percent of the time” and “primary care doctors using those methods got it right only 61 percent of the time.” The findings were published in JAMA and presented at the Alzheimer’s Association International Conference.
