TL;DR: People recovering from stress-related exhaustion who did 12 weeks of computer brain training showed larger gains in thinking scores over 4.5 years than people who got rehab alone. Indoor cycling did not show the same lasting edge, but only 56 of 132 peo…

TL;DR: When a piece of music ended differently than people expected, they were a bit more likely to remember pictures they saw around that moment a day later. The effect was small and showed up in trial-by-trial analyses, not in simple group averages. Key Find…

TL;DR: In rats given the chemotherapy drug doxorubicin, which caused memory problems, adding the antipsychotic lurasidone protected memory on maze and object tests. This was a prevention study in male rats, not a treatment for people with “chemo brain.” Key Fi…

TL;DR: Young mice carrying the human APOE4 gene, the biggest genetic risk factor for Alzheimer’s, had overexcited memory circuits months before any memory trouble showed up. Removing APOE4 from their neurons returned those cells to normal. Key Findings Early w…

TL;DR: Women who reported 10+ brain injuries from a partner performed on a speed test like someone about 21 years older than their actual age. They scored about 11 years “older” than survivors with no brain injury; the study of 207 women found a link, not proo…

TL;DR: A 2026 rat study in Hippocampus found that the dentate gyrus (DG), a hippocampal memory region, gained about 385,000 granule neurons from 2 to 18 months of age even though older development-born neurons were also being lost. Key Findings 385,000-cell ne…

Loneliness Lowered Memory Without Speeding Decline TL;DR: In 10,217 older Europeans, loneliness was linked to lower immediate and delayed recall at baseline, but it did not make memory decline faster over 6 years. Key Findings 10,217 SHARE participants: The an…

Dopamine Disruption May Start Alzheimer’s Memory Failure TL;DR: In an Alzheimer’s mouse model, early memory failure tracked a broken dopamine signal into the lateral entorhinal cortex, and both optogenetic dopamine reactivation and L-DOPA partially restored le…

Cannabis Did Not Just Blur Word Lists. It Hit Everyday Memory Too TL;DR: A randomized vaporized-THC trial found broad acute memory impairment, including false memories, prospective memory, source memory, and temporal order memory, with no meaningful dose split…
