A 2026 survey of 230 Farsi-speaking refugees in German camps found a hard double signal: 69.1% screened above the RHS-15 threshold for depression, anxiety, and PTSD symptoms, while 4 protective factors explained 61% of posttraumatic-growth variance.1 Research Highlights High distress and growth coexisted: 159 of 230 participants (69.1%) scored ≥12 on the RHS-15 symptom scale, …
A 2026 nuMoM2b Heart Health Study analysis tested whether urine-confirmed cannabis exposure 2–7 years after a first pregnancy predicted incident stage II hypertension; it did not: adjusted odds ratio (AOR) 1.05, 95% CI 0.63–1.76, with 216 of 4,079 participants developing hypertension.1 Research Highlights The headline result was null: cannabis exposure at the 2–7 year postpartum …
A 2026 UK Biobank MRI preprint involving 71,214 adults found that chronic pain plus current depression had a structural brain profile that was more than chronic pain plus depression pasted together. The 1,377-person comorbid group showed widespread lower cortical volume, lower bilateral thalamic and hippocampal volume, lower left accumbens volume, and broad white-matter microstructure differences …
A 2026 double-blind randomized controlled trial by Kappes et al. in Psychopharmacology found something the smart-drug users likely wouldn’t have predicted: a single 30 mg dose of methylphenidate reduced dishonest misreporting on a die-rolling task from ~22% of trials in the placebo arm to ~6% (in the methylphenidate arm).1 Atomoxetine, a noradrenergic comparator, had no …
Deep brain stimulation works for Parkinson’s, but it requires implanted electrodes. A 2026 randomized crossover trial by Stalter and colleagues tested whether transcranial temporal interference stimulation — a non-invasive technique designed to reach deep targets without exciting overlying cortex — can move the needle on motor symptoms when aimed at the putamen.1 Research Highlights Transcranial …
Most antidepressant pharmacovigilance data come from high-income countries, leaving prescribing patterns and adverse-effect profiles in low- and middle-income countries underdocumented. A 2026 cross-sectional study by Riaz and colleagues describes antidepressant use in Pakistan, with patient-reported adverse effects mapped against prescription patterns.1 Research Highlights Antidepressant use in low- and middle-income countries (LMICs) has grown substantially but …
Parkinson’s disease has a years-to-decades prodromal stage where motor symptoms haven’t yet emerged but pathology is accumulating. A 2026 review by Schaeffer et al. synthesizes the case for (and limits of) intervening during this window — with implications for high-risk individuals weighing whether to enter preventive trials.1 Research Highlights Prodromal Parkinson’s disease is the period …
