Trauma Cues Increased Substance Craving via Negative Affect in Meta-Analysis

TL;DR: A 2026 meta-analysis in European Journal of Psychotraumatology found that trauma cues increased substance craving in trauma-exposed people who use substances, and the strongest pathway ran through cue-triggered negative affect. Key Findings 32 studies: Researchers synthesized trauma cue-reactivity studies from 21 unique datasets. Craving increased with trauma cues: Trauma reminders produced higher craving than …

Prion Disease Models Linked Delayed UPR to Toxic Protein Spread

TL;DR: A 2026 modeling study in Journal of Mathematical Biology found that delayed unfolded protein response (UPR), a cellular stress program that slows protein production, could make toxic prion protein either die out, persist, or oscillate as it spreads through a brain-connectome model. Key Findings The model tracked PrPC and PrPSc: Researchers modeled normal cellular …

Evidence Accumulation Predicted Cigarette and Cannabis Use

TL;DR: A 2026 study in Neuropsychopharmacology found that decision-making measures from a stop-signal task, especially evidence accumulation, predicted cigarette and cannabis use better than stop-signal reaction time (SSRT), a common estimate of response inhibition. Key Findings More than 1,000 young adults: The analysis used IMAGEN cohort stop-signal task data from 1,256 participants at age 19 …
