Early Risers at Lower Risk for Depression
The researchers examined this question: Does a tendency toward sleeping and waking earlier have a potential causal role in reducing the risk of major depressive disorder?
Suicide Prediction Models May Promote Racial Inequity
The researchers asked whether implementing suicide prediction models reinforces and worsens racial and ethnic disparities in care.
Meningeal Lymphatic Drainage May Help Improve Alzheimer Disease Outcomes
Using transcriptional profiling of mouse meningeal lymphatic endothelial cells, microglia and brain blood endothelial cells, the researchers showed that meningeal lymphatic function is coupled to microglia and brain vascular activation in Alzheimer disease.
Approach Bias Retraining With Virtual Reality Technology Reduces Smoking
The researchers combined virtual reality with Approach Bias Modification to determine if this would improve smokers’ motivation to quit smoking and reduce the number of dropouts from smoking cessation programs.
Sleep-Deprived Adults at Higher Risk for Dementia
While sleep dysregulation is a feature of dementia, it remains unclear whether the duration of sleep prior to old age is associated with dementia. The researchers examined the association between sleep duration and incidence of dementia using a 25-year follow-up.
Opioid Exposure Increases Risk of Infant Death
The study authors examined the risk of mortality in opioid-exposed infants, and whether mortality is associated with neonatal opioid withdrawal syndrome (NOWS).
Younger Teens Highly Susceptible to Lifetime Substance Abuse
The researchers examined data for individuals age 12 to 25 from national surveys on drug use and looked at initiation dates, use in the past 12 months, lifetime use, and diagnosed substance use disorders.
Zoom Fatigue Is Real, and More Women Experience It Than Men
The study authors investigated the fatigue that can take place in video calls and/or by the additional cognitive load these calls require.
Keto Diet Reduces Alcohol Withdrawal Symptoms
According to the study, individuals with alcohol use disorder (AUD) show elevated brain metabolism of acetate at the expense of glucose. The study authors hypothesized that a shift in energy substrates during withdrawal may contribute to withdrawal severity
and neurotoxicity in AUD and that a ketogenic diet may mitigate these effects.
