TL;DR: A 2026 study in the International Journal of Transgender Health found that transgender respondents in the 2020 EU LGBTI Survey II reported more discrimination and violence than cisgender lesbian, gay, and bisexual respondents across 30 European countries, with disability and ethnic-minority status linked to larger disparities. Key Findings 138,212 respondents analyzed: the study used …
TL;DR: A 2026 randomized trial in PLOS One found that 5 MIDI-assisted group music therapy sessions during psychiatric hospitalization reduced Depression Anxiety Stress Scale-21 (DASS-21) stress scores more than 1 session, while anxiety, depression, life satisfaction, and immediate emotional-response measures did not clearly differ by session frequency. Key Findings Stress fell further: DASS-21 stress showed …
TL;DR: A 2026 randomized trial analysis in European Journal of Psychotraumatology found that COPE-A, an integrated exposure-based therapy for youth with posttraumatic stress disorder (PTSD) and substance use disorder (SUD), reduced PTSD symptoms more than supportive counseling, but substance-use reductions were not significantly stronger than counseling. Key Findings 49 treated participants were analyzed: Youth aged …
TL;DR: A 2026 study in Communications Psychology analyzed 1,687 dream reports and 1,679 waking reports, finding that dreams were more visual, spatial, social, bizarre, and emotionally negative than waking experiences. Key Findings 3,366 reports analyzed: the main dataset included 1,687 dream reports and 1,679 waking reports from 207 adults collected between 2020 and 2024. Dreams …
TL;DR: A 2026 study in The Journal of Neuroscience found that adults with ADHD showed more sleep-like brain waves, known as slow waves, while awake, and those brief local sleep states helped explain lapses in attention and vigilance. Key Findings 32 ADHD adults tested: The study compared 32 medication-free adults with ADHD with 31 neurotypical …
TL;DR: A 2026 three-wave experimental study in Communication Research (N=3,000+ adults across the US and the Netherlands) found that AI-generated political deepfake videos damaged the reputations of targeted politicians even when viewers correctly suspected the footage was fake — and standard fact-checks restored authenticity perception without reversing the reputational harm. Key Findings Three-wave experiment, 3,000+ …
TL;DR: A 2026 study in npj Mental Health Research found that a 308-person multimodal MRI study found treatment-resistant depression carried a distinct structure-function decoupling pattern, and machine-learning models separated TRD from non-resistant depression with AUCs up to 0.95. Key Findings 72 TRD patients analyzed: The final sample included 72 patients with treatment-resistant depression, 152 with …
TL;DR: A 2026 study in PNAS found that across convention-learning experiments, people explored uncertain options at first, then committed once enough evidence crossed a Tolerance Principle threshold rather than simply copying others or optimizing probabilities. Key Findings Two-stage learning fit behavior: Participants behaved probabilistically while uncertain, then shifted into stable choices once accumulated evidence crossed …
TL;DR: A 2025 study in Nutrients found that a systematic review of adolescent diet and mental health found the clearest readout for whole dietary patterns, while single nutrients and supplement-style interventions looked less consistent. Key Findings 19 studies reviewed: The review covered six randomized controlled trials and 13 prospective cohort studies. Diet patterns looked clearer: …
TL;DR: A 2026 human microbiome and intervention study in Nature Communications found that coffee drinkers showed distinct gut microbiome composition and lower several microbial metabolites, while caffeinated and decaffeinated coffee shifted stress and mood measures in the intervention phase. Key Findings Study type: a study of habitual coffee intake, caffeinated and decaffeinated coffee, gut microbes, …
