Healio (7/1, Gramigna) reports, “Eating disorder behaviors appeared to change brain reward processing,” researchers concluded in a functional brain imaging study that sought “to evaluate brain response during unexpected receipt or omission of a salient sweet stimulus in 317 women, of whom 197 had eating disorders and 120 served as healthy controls, and to determine whether this brain response was linked to the ventral striatal-hypothalamic circuitry, which has correlated with food intake control.” The study revealed that “BMI modulated prediction error and food intake control circuitry in the brain, and alteration of this circuitry may reinforce eating disorder behaviors when paired with behavioral traits linked to overeating or undereating, researchers noted.” The findings were published online June 30 in JAMA Psychiatry. HealthDay (7/1, Preidt) also covers the study.

Psychiatric News (6/30) reports, “Paid family leave policies enacted by states for new parents appear to improve mental health and decrease psychological distress of new parents,” researchers concluded after analyzing “data collected between 1997 and 2016 as part of the annual National Health Interview Survey,” then comparing “changes in parental psychological distress (as determined by the Kessler 6 score) and child behavioral problems (as determined by the Mental Health Indicator score) among families in California and New Jersey before and after implementation of paid family leave policies.” The findings were published online June 28 in the American Journal of Preventive Medicine.

Psychiatric News (6/29) reports, “People with substance-induced psychosis appear to be at a greater risk of dying earlier than those who do not experience psychosis,” investigators concluded in a study that included 9,303 people who “were diagnosed with substance-induced psychosis only, 2,197” who were “were diagnosed with schizophrenia following substance-induced psychosis, and 39,738” who “were diagnosed with schizophrenia without preceding substance-induced psychosis.” The study population “was followed until death, emigration, or August 10, 2017, whichever came first.” The study “revealed that the risk of death was elevated in people with substance-induced psychosis regardless of whether they later developed schizophrenia.” The findings were published online June 9 in the journal Addiction.

Healio (6/29, Gramigna) reports, “Antipsychotic-naive patients with first-episode psychosis exhibited widespread functional dysconnectivity at baseline,” researchers concluded in a “secondary analysis of a randomized clinical trial” that included data on “59 antipsychotic-naive patients with first-episode psychosis receiving either a second-generation antipsychotic or a placebo…over six months of treatment,” as well as 27 healthy individuals who served as controls. Study participants underwent resting state functional magnetic resonance imaging at “baseline, three months and 12 months…with data analysis between May 2019 and August 2020.” The findings were published online June 23 in JAMA Psychiatry.

Healio (6/28, Gramigna) reports, “Young adults with or without depression who used cannabis had higher prevalence of suicidal ideation, plan and attempt,” investigators concluded after conducting “a survey study using data from 281,650 adults aged 18 to 34 years who participated in the National Surveys on Drug Use and Health, with data collection between 2008 and 2019.” The study also revealed that “past-year cannabis use disorder, daily cannabis use and nondaily cannabis use were associated with a higher prevalence of past-year suicidal ideation, plan and attempt among both sexes; however, women were more affected than men.” The findings were published online June 22 in JAMA Network Open.
