Researchers discovered adults who consumed heavier amounts of sweeteners showed a 62% faster decline.

New research shows that breathing fine particulate air pollution is associated with a decline in semantic memory among older Black adults. The findings highlight how environmental factors may contribute to racial disparities in dementia.

Scientists at the University of California, San Francisco have identified a protein called FTL1 that appears to play a central role in brain aging. In aging mice, higher levels of FTL1 were linked to weaker connections between neurons in the hippocampus, the brain region critical for learning and memory, as well as to poorer performance on cognitive tests. When researchers artificially increased FTL1 in young mice, their neurons developed simpler, less branched structures and their behavior became more like that of older animals, suggesting that FTL1 can accelerate signs of brain aging. The team also found that FTL1 dampens the metabolic activity of brain cells, slowing how they use energy in the hippocampus. In contrast, when FTL1 levels were reduced in older mice, the animals showed signs of recovery: connections between neurons increased and their memory performance improved, indicating a partial reversal of age‑related impairment. In some experiments, boosting cellular metabolism with a metabolic compound prevented the negative effects of high FTL1, hinting at a potential therapeutic strategy. The researchers believe targeting FTL1 or its downstream metabolic effects could open new paths for treatments aimed at mitigating cognitive decline in aging, although the work is still in early, preclinical stages in mice.

High-Salt Diet Linked To Faster Memory Decline In Men.

This study reveals a role for hypothalamic Menin in organismal aging in mice, finding that Menin expression decreases in hypothalamic neurons during aging; mimicking this decrease induces premature ag...
