Mind the gap they named

Academic editorials are not where you go for warmth, but this one is worth reading for a single honest sentence buried in the optimism. After surveying the wearables that detect agitation in real time and the deep-learning models that spot Alzheimer's early, the authors note a "substantial gap in accessible information and training" for informal caregivers.

That gap is the whole story. The sensors are getting good. The models are getting accurate. And the daughter managing her mother's dementia at 11 p.m. still cannot find a clear, mobile-friendly answer to the question in front of her. Most of the dementia-tech conversation is about detection — telling families something is wrong. Far less of it is about navigation — telling families what to do next. The technology in this paper is real and improving. The gap it names, almost in passing, is the one that actually decides whether any of it reaches the people doing the caring.
