The bottom line
Brain health is becoming a larger focus of science, diagnostics and prevention as populations age and cognitive health receives more sustained attention.
Why it matters
The opportunity spans earlier detection, neurological research, digital assessment and new interventions. The strategic pressure comes from the gap between rapidly growing need and the slower pace at which effective interventions scale.
From the foresight archive
Jim Carroll first published this as Megatrend #13 on 2025-07-14. He revisited it one year later on 2026-08-21, using the retrospective to test the original call against what had happened since.
In that retrospective, Carroll’s own shorthand assessment was: Underway, but the urgency is outrunning the interventions. The tech pillars are genuinely advancing; the demographic wave they’re supposed to meet is arriving faster than any of them will scale.
This page treats the 2025 article as the original foresight call and the 2026 article as the first evidence checkpoint. Later signals and scorecards can be attached without rewriting the historical record.
