TL;DR: When 22 young adults tried to recall where they had seen everyday objects, their eyes drifted toward the right spot before they answered. The closer their gaze, the more precise their memory turned out to be. Key Findings Eyes found the spot: Gaze landed much closer to an object’s original place when people truly …
TL;DR: In a tiny pilot study, a few minutes on an exercise bike boosted thinking speed scores by about 7 points in healthy adults but only about 2 points in people with relapsing-remitting multiple sclerosis. With 10 people per group, it is an early clue, not a firm result. Key Findings 20 adults: 10 with …
TL;DR: When 60 volunteers braced for a shock they could dodge with a quick button press, their brains and bodies shifted into a focused, alert state. But they remembered faces seen during those moments no better than faces seen when they felt safe. Key Findings 60 adults, 270 trials: Each face came with a certain …
TL;DR: Among 112 older adults in Spain with mild cognitive impairment, those who reported more physical activity and felt more supported by family and friends scored better on several thinking tests. The study took one snapshot, so it cannot show that activity or support protects thinking. Key Findings 112 adults, average age 71: All had …
TL;DR: In a German study of 34 people recovering from LGI1 encephalitis, a rare autoimmune brain disease, brain scans showed changes well beyond the memory centers usually blamed. People with more of these changes had poorer thinking scores and recovered less. Key Findings Most improved: Median disability score fell from 3 at the worst point …
TL;DR: People with a common type of heart failure scored lower on thinking tests than healthy people of similar age, and an MRI sign of the brain’s fluid-clearing system was lower on the left side of their brains. Lower values of that sign went with lower thinking scores. Key Findings Lower thinking scores: Average MoCA …
TL;DR: Teenage girls on a national youth soccer team who swapped two practices a week for weight training got stronger and did better on a classic focus test than teammates who kept their usual practice. Blood markers often linked to brain growth did not change. Key Findings 22 players, 12 weeks: Weight training plus soccer …
TL;DR: Among Hispanic and Latino adults in the U.S., people with one particular DNA pattern around the APOE gene were more likely to show steep thinking decline over about 7 years. The well-known APOE4 risk version had a weaker link in the same group. Key Findings 3 DNA profiles: Short DNA sequences near APOE sorted …
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 people came back. Key Findings Brain training held up: Bigger gains than …
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 Findings 60 young adults: Listened to Bach chorales while viewing neutral …
