AI vs. Dementia: How Technology is Rewriting the Rules of Detection

We’re living in a world where artificial intelligence can detect skin cancer, translate languages in real time, and even compose symphonies. So why are we still diagnosing dementia using the same tools we used decades ago?

The truth is, while dementia affects nearly one million people in the UK, diagnosis is often delayed until after the damage is done. By the time traditional tests confirm cognitive decline, the condition has already progressed, and families are left with fewer options.

At SynaptiSense, we believe AI is the key to changing that reality.

The Diagnostic Gap

Current diagnostic methods — like memory recall tests or MRI scans — are valuable, but they come with limitations:

• They require access to specialists.

• They tend to detect problems only once symptoms are pronounced.

• They often miss subtle, early signs that precede measurable decline.

As a result, people are diagnosed too late — when interventions are less effective and quality of life has already begun to decline. This delay can cost families more than time. It can cost independence, emotional well-being, and financial security.

AI offers a different path — one based on pattern recognition, predictive modelling, and continuous insight.

What AI Does Differently

Artificial intelligence thrives where humans and conventional systems struggle: with early, complex, and subtle data patterns. At SynaptiSense, we’re developing an AI-powered tool that analyses four behavioural and biological streams to identify dementia risk 5–7 years before symptoms appear.

These include:

• Speech patterns – tracking shifts in word usage, sentence structure, and pacing

• Cognitive game results – monitoring how people respond to challenges over time

• Wearable metrics – such as heart rate variability, sleep quality, and step count

• Behavioural signals – like changes in routine, app usage, or motor activity

Using AI, we can synthesise this diverse information to detect micro-changes invisible to the human eye — but highly predictive of future decline.

This isn’t science fiction. It’s evidence-based, user-tested, and rapidly becoming a new frontier in proactive healthcare.

Accuracy and Accessibility

In early testing, our platform has already achieved:

• 96% accuracy in wearable data biomarker identification

• A 4.9/5 star rating from users of our cognitive app prototype

• Strong engagement from individuals spending 18+ minutes per day on cognitive tasks

But perhaps most importantly, our approach doesn’t rely on hospital visits or invasive tests. It’s designed to be accessible, affordable, and delivered through technology you already use — your smartphone and wearable device.

This democratisation of dementia detection could shift the focus of brain health from clinical settings to everyday living.

Why This Matters Now

AI has already revolutionised how we bank, shop, and travel. It’s time it did the same for healthcare — particularly for conditions like dementia, where time is everything.

An earlier diagnosis means more time to:

• Plan for the future

• Access support

• Start interventions

• Preserve quality of life

And for healthcare systems like the NHS, AI-powered early detection could reduce economic strain, ease patient load, and increase effectiveness of services.

The earlier we detect dementia, the more we can do about it. That’s the power of AI — and it’s a future SynaptiSense is building right now.
