The Science of Seeing Sooner: How Cutting-Edge Research Is Changing What's Possible for Families
Earlier this week, Georgetown University's Center for Security and Emerging Technology published an analysis of how prize competitions can accelerate AI-driven scientific discovery. They were examining which competitions best exemplify how we can use innovation challenges to advance science — and they chose the PREPARE Challenge as their lead example.
PREPARE — Pioneering Research for Early Prediction of Alzheimer's and Related Dementias — was a competition to improve detection of cognitive decline before a clinical diagnosis, by bringing together data scientists, clinicians, and AI researchers to build better prediction tools.
I led that challenge. It was one of the most rewarding experiences of my career — seeing a concept move from whiteboard to execution to a launchpad for translation into clinical practice. It came in on the tailwinds of a revolution that is shaking up how we treat diseases like Alzheimer’s disease.
A Revolution in Early Detection
For decades, the tools available for detecting Alzheimer's disease and related dementias were blunt instruments. By the time a diagnosis arrived, years of gradual change had already passed — years when families might have planned differently, acted sooner, or simply understood what they were seeing.
That reality is changing fast, across multiple scientific fronts at once.
The blood is talking. A new generation of blood tests can now detect the biological signatures of Alzheimer's disease — the protein buildups in the brain that were previously visible only through expensive brain scans or spinal taps. One of these tests received FDA approval in 2025. A simple blood draw can now provide information that once required a $5,000 imaging procedure. These tests aren't perfect screening tools yet, but they're transforming how clinicians evaluate cognitive concerns, especially when combined with other information.
Digital tools are catching what traditional tests miss. Researchers have developed computerized cognitive assessments that measure not just whether you got the answer right, but how you got there — the hesitations, the timing, the subtle shifts in processing speed that a paper-and-pencil test can't capture. Some of these tools can identify risk years before traditional screening methods raise a flag.
Voice and language patterns carry hidden signals. One of the most striking findings from recent research — including work that emerged through PREPARE — is that changes in speech and language can contain early markers of cognitive change. The way someone organizes a sentence, pauses between thoughts, or retrieves words can shift in detectable ways well before anyone in the room notices.
AI is connecting the dots. Machine learning algorithms can now integrate information across these different streams — blood markers, cognitive performance, speech patterns, medical history, even social and environmental factors — to build prediction models that outperform any single measure alone. PREPARE was designed to accelerate exactly this kind of work, and the results confirmed that combining diverse data sources yields meaningfully better early detection.
What the Science Can Do vs. What Families Actually Receive
Here's the gap that motivated to start Treasure Coast Cognition.
This revolution in early detection is real. The science works. But almost none of it reaches families during the window when it matters most.
During this window, if you bring cognitive concerns to your doctor, you'll likely hear some version of: "It's probably normal aging. Let's keep an eye on it." That's not negligence — it's a system that isn't designed to act on early, ambiguous signals.
Meanwhile, the science now exists to characterize those early changes with far greater precision. Blood biomarkers can clarify biological risk. Sensitive cognitive assessments can establish baselines and track trajectories over time. Integrative analysis can distinguish between normal age-related variation and something that warrants closer attention and proactive planning.
The problem isn't the science. The problem is that no one is translating it for families in a way that leads to action.
Why I Built Treasure Coast Cognition
The neuroscience of cognitive aging, the early behavioral and biological markers of decline, the gap between research capability and clinical reality is the reason for Treasure Coast Cognition.
The clearest thing I learned was this: the families who navigate cognitive change best are the ones who start paying attention early — not after a crisis, not after a diagnosis, but during the window when understanding and planning are still fully available.
That's what Cognitive Stewardship is. It's the practice of proactively monitoring cognitive health, interpreting the signals that matter, and building a plan that protects independence, finances, and family relationships — grounded in the best available science.
Treasure Coast Cognition exists to be the bridge between what cutting-edge research can now detect and what your family actually needs to know and do. We take the same science that Georgetown just highlighted as a model for innovation, and we make it personal, ongoing, and actionable.
What This Means for You
If you're watching a parent, spouse, or loved one and wondering whether what you're seeing is "just aging" or something more — that uncertainty itself is a signal worth taking seriously.
Not because it necessarily means something is wrong. But because the science now exists to give you a clearer answer than "wait and see." And because the decisions that matter most — about legal authority, financial oversight, care preferences, living arrangements — are far better made with time and clarity than under pressure.
The revolution in early detection isn't coming. It's here. The question is whether your family has access to someone who can translate it into guidance that actually matters for your life.
That's the work we do.
