A 2026 whole-genome sequencing preprint found rare variant signals in 2 multiplex obsessive-compulsive disorder (OCD) families: an NPY5R missense variant in 10 of 15 affected people in 1 pedigree, plus DLGAP1 and MAPK8IP3 signals that tracked all 3 sequenced cases in a branch of a second pedigree.1 The finding is a candidate-gene result, not a …
A 2026 Phase I crossover trial found that a 400-mg powdered cannabidiol formulation reached peak CBD faster than Epidyolex oil in healthy adults — 3 h vs. 3.5 h when fasted and 5 h vs. 8 h after a high-fat meal — but food still dominated the exposure story.1 Research Highlights Faster peak: CBtru powder …
A 2026 participatory-design and case-study paper turned smartphone mental-health data into 6 clinician-facing visualizations for an 8-week anxiety/depression digital clinic, using feedback from 15 clinicians and 3 clinical supervisors. The useful claim is workflow-level: charts made passive sensing and symptom ratings discussable inside care, but the paper did not test whether the visualizations improved clinical …
A 2026 Singapore birth-cohort preprint found a conditional childhood-anxiety signal: the cord-blood DNA methylation component predicted less age-13 anxiety only in boys in the low DMN-limbic trajectory group from ages 4.5 to 10.5 years. The paper is useful for mapping developmental risk biology, but it is not a screening test and it does not show …
A 2026 nationwide Korean analysis found that resistance exercise was associated with lower depression and anxiety scores after propensity score matching, while aerobic exercise alone was not significantly associated with either outcome. The result favors adding weights, bands, machines, or body-weight strength work to mental-health exercise advice without assuming that lifting caused the lower symptom …
The endogenous opioid system has been a candidate target for novel anxiety treatments, but a 2026 placebo-controlled crossover fMRI study in 38 healthy volunteers ran opposite the hypothesis: instead of increasing threat-related distress and amygdala reactivity, 50 mg oral naltrexone reduced subjective distress during cognitive reappraisal (p = 0.044, d = 0.57) and shifted ventromedial …
A 2026 task-based fMRI study of 91 young adults separated misophonia from hyperacusis inside the same “sound sensitivity” experiment: misophonia-containing groups showed visual association cortex and ACC-visual network changes during unpleasant sounds, while key hyperacusis contrasts showed weaker salience-control connectivity than misophonia.1 The scan data support separating trigger-specific sound aversion from loudness-driven sound intolerance, while …
