AI and wearables helping track dementia risk in India

There's a piece out of USC about how AI plus wearable devices are being used in India to study speech patterns in older adults, as part of the LASI-DAD project looking at population-level dementia risk. Basically they're using small wearables to capture speech and other signals, then running machine learning on it to flag early cognitive decline before someone walks into a clinic with obvious symptoms.

What caught my eye is the scale of it. Most cognitive studies I've read about are tiny, 50 people here, 100 there. This is trying to do something at population level in a country where dementia is massively underdiagnosed, which honestly makes sense to me. Early detection is the part nobody talks about enough. By the time someone gets a formal diagnosis, a lot of damage is already done.

It's still research, not a product you can use tomorrow. But if speech biomarkers actually hold up, it could change how screening works. Does anyone here actually track their own cognition over time with anything objective, or is it all subjective notes?
