Curcumin and Ginger May Help Memory, But Not Other Brain Functions
Based on: Effects of Zingiberaceae-derived interventions on memory-related and other cognitive outcomes in adults: a systematic review and meta-analysis.
Looking at 18 trials, researchers found that compounds from the ginger family, including curcumin and turmeric, modestly improved memory in adults. The same compounds did not help with attention, executive function, or overall thinking. The authors caution the evidence is shaky due to small studies and big differences in how curcumin was prepared.
Key Insight
This review suggests curcumin and ginger compounds may be associated with memory improvements, though the evidence is weak.

How Polyphenols From Tea, Berries, and Curcumin May Slow Aging Pathways
This review looks at how common plant compounds like resveratrol, EGCG from green tea, curcumin, and quercetin may influence aging. They appear to nudge the same pathways targeted by longevity drugs, including AMPK, sirtuins, and mTOR. They also feed gut bacteria that produce urolithin A, a compound linked to better mitochondrial health.
Staying Active in Your 40s and 50s Tied to Sharper Thinking Decades Later
Pooling data from eight studies covering over 33,000 people, researchers found that higher physical activity in midlife was linked to modestly better memory, mental processing speed, and overall thinking ability later in life. The effects were small but consistent across multiple cognitive domains. However, the results for executive function and verbal fluency weren't meaningful. Almost all studies relied on self-reported exercise, and only one looked at men and women separately.
Living Near Parks Linked to Sharper Thinking in Older Adults
In over 62,000 older adults across Beijing, living closer to green spaces was tied to better scores on cognitive tests. The connection held whether researchers measured actual greenery, park distance, or how much green people could see. A key finding: cognitive scores dropped noticeably once people lived more than 500 meters from a park. The study controlled for demographics and environmental factors across 324 community health centers.
