A 2025 scoping review of 292 adult ADHD randomized controlled trials found that 49.7% allocated diagnosis without a general psychopathology assessment, and only 35% reported that psychiatrists or psychologists assigned the ADHD diagnosis. Research Highlights 292 adult ADHD RCTs were reviewed: Studart et al. screened 706 PubMed records and included 292 randomized controlled studies.1 49.7% …
A 2026 PROTECT study involving 174 older adults found that self-administered fingerprick p-tau217 correlated with episodic memory (r = 0.299, p < 0.001) and GFAP correlated with working memory (r = 0.183, p = 0.034), supporting remote Alzheimer's risk triage rather than a stand-alone dementia diagnosis. Research Highlights Fingerprick sampling reached 77% completion: 174 of …
A 2026 ANTLER mechanistic analysis found no evidence that maintaining antidepressants preserved a happier facial-emotion recognition pattern compared with placebo substitution at 12 weeks (adjusted mean difference 0.23, 95% CI −0.5 to 1.0, p = 0.5) or 52 weeks (0.29, 95% CI −0.5 to 1.2, p = 0.5). Research Highlights No 12-week maintenance advantage: discontinuation …
A 2-experiment BMC Biology study found that female body-size judgments did not require a full-body view: bottom-half views preserved accuracy in 99 women, while isolated inner- or outer-thigh views produced more perceptual error than whole-body views in a second 116-woman experiment.1 The result is relevant to body-image research because it points to lower-body feature integration, …
A 2026 PLOS Biology study using 256-electrode EEG and 1,024 NREM2 awakenings found that immersive dreaming predicted deeper subjective sleep, beta = 0.277, while reflective thought predicted shallower subjective sleep, beta = −0.195.1 Deep-feeling sleep can include immersive conscious experience. Research Highlights Immersion predicted depth: Perceptual immersion in NREM2 dreams was positively associated with subjective …
A 2026 Parkinson’s disease mouse study reported that benzhexol hydrochloride induced a measurable hallucination-like behavior state in 6-OHDA parkinsonian mice, and an integrated behavior classifier separated that state from non-PDVH mice with AUC = 0.96 and Youden index = 0.875.1 The careful interpretation is behavioral modeling, not proof that mice had human visual hallucinations. Research …
A 2026 Psychological Medicine study involving 196 healthy adults found that transcranial direct current stimulation over the right temporoparietal junction increased cognitive empathy signals across pain and video tasks, while left dorsolateral prefrontal cortex stimulation produced narrower and less consistent effects.1 The useful finding is anatomical calibration: rTPJ looked more like an other-state representation target, …
