7Disadvantaged neighborhoods tie to lower brain vascular function
In 132 older adults, greater neighborhood deprivation was associated with lower whole-brain cerebrovascular reactivity, independent of traditional…In 132 older adults, greater neighborhood deprivation was associated with lower whole-brain cerebrovascular reactivity, independent of traditional vascular risks and Alzheimer's pathology.
Brain small vessel disease links to stroke and mortality risk
Compared with a zero score, participants with cerebral small vessel disease scores of 1 and 2 had hazard ratios of 1.48 and 1.52 for adverse events.Compared with a zero score, participants with cerebral small vessel disease scores of 1 and 2 had hazard ratios of 1.48 and 1.52 for adverse events.

Across about 80,000 human participants, simple anatomical measurements performed as well as complex AI models while improved pretraining boosted…Across about 80,000 human participants, simple anatomical measurements performed as well as complex AI models while improved pretraining boosted biological age estimation.
Automated tool counts teeth from routine brain MRI
The model counted teeth with a mean absolute error of 1.96 and matched manual associations with cognitive scores in a 233-person cohort.The model counted teeth with a mean absolute error of 1.96 and matched manual associations with cognitive scores in a 233-person cohort.
