TL;DR: A 2026 study in Journal of Korean Medical Science found that resistance exercise was more consistently associated with lower depression and anxiety scores than aerobic exercise in Korean adults, but the cross-sectional design means the study cannot prove exercise caused the mental-health difference. Key Findings Resistance exercise had the strongest association with lower Patient …
TL;DR: A 2026 preprint in medRxiv used whole-genome sequencing in two families with many obsessive-compulsive disorder (OCD) cases and prioritized rare variants in NPY5R, DLGAP1, and MAPK8IP3, but the findings still need replication and functional testing. Key Findings Two densely affected families: Researchers sequenced 25 people from two multiplex OCD pedigrees, meaning families with several …
TL;DR: A 2026 preprint posted to medRxiv found that intermittent theta-burst transcranial temporal interference stimulation (iTBS-tTIS), a noninvasive electrical method aimed at the right putamen, lowered left-sided Parkinson’s motor scores during stimulation in 19 patients. Key Findings 19 Parkinson’s patients and 19 healthy controls completed a randomized, double-blind crossover stimulation study. MDS-UPDRS III, the motor …
TL;DR: A 2026 medRxiv preprint found that older adults with Montreal Cognitive Assessment (MoCA)-defined mild cognitive impairment had less coordinated pulse-wave responses during a cognitive challenge than cognitively intact older adults. Key Findings Community cognitive-aging sample: The southern Taiwan dataset included 101 older adults: 12 reference participants, 50 people in a MoCA-defined mild cognitive impairment …
TL;DR: A 2026 Molecular Psychiatry ENIGMA mega-analysis found that medication status in bipolar disorder was linked to subtle differences in subcortical brain volume, with antiepileptic and antipsychotic exposure most consistently tied to smaller hippocampal and thalamic volumes. Key Findings 6,729-person ENIGMA sample: Researchers pooled MRI data from 2,664 people with bipolar disorder and 4,065 controls …
TL;DR: A 2026 cross-sectional study in Nature and Science of Sleep linked second-trimester sleep disturbance, measured with the Pittsburgh Sleep Quality Index (PSQI), to depressive symptoms, vomiting, diet quality, and several birth-outcome patterns in 2,210 pregnant women in Wuhan, China. Key Findings Sleep disturbance affected 18.14%: 401 of 2,210 pregnant women had PSQI scores above …
TL;DR: A 2026 study in Advanced Science found that flexible polyimide brain-implant probes produced lower long-term tissue reactivity than stiff silicon electrodes, while thinner probe designs and skull-detached mounting mattered less than the implant material itself. Key Findings Material mattered most: Flexible polyimide probes triggered less brain-tissue reactivity than stiff silicon electrodes. Not reaction-free: Polyimide …
TL;DR: A 2026 study in Clinical Case Reports described persistent genital arousal disorder in a woman in her 30s, with symptom improvement after combined risperidone, sodium valproate, fluoxetine, short-term clonazepam, relaxation work, and cognitive behavioral strategies. Key Findings Five-month symptom course: The patient reported spontaneous genital tingling, throbbing, and warmth without sexual desire or fantasy. …
TL;DR: A 2024 study in Journal of Political Ideologies linked perceived grievance, a belief that society is structured around group-based oppression, with left-wing authoritarianism through psychological distress and individualizing moral concerns. Key Findings Grievance link: Perceived grievance was the strongest direct predictor of left-wing authoritarianism in the tested model. Distress pathway: Depression, anxiety, and stress …
TL;DR: A 2026 study in PLOS One found that people with Parkinson’s disease made more silent pauses while reading aloud, especially when sentences were longer or syntactically more complex. Key Findings Reading task compared 71 adults: Researchers compared 32 people with Parkinson’s disease and 39 older control participants. Parkinson’s readers paused more often: The Parkinson’s …
