Cognitive Testing,
Backed by Science.

We use Creyos — a validated digital platform built on decades of neuroscience — to objectively measure how your brain is really performing, so your diagnosis rests on real data.

What It Is

Objective Insight
Into Your Mind

Creyos (formerly Cambridge Brain Sciences) is a scientifically validated cognitive assessment platform used by clinicians worldwide. It measures core brain functions — like attention, memory, and reasoning — through short, engaging online tasks.

Instead of relying on guesswork or self-report alone, Creyos gives us objective, data-driven insight into how your brain is really performing — so your diagnosis and care plan are built on real evidence.

Common Questions

Questions, Answered

What is Creyos?

Creyos (formerly Cambridge Brain Sciences) is a scientifically validated digital platform for cognitive assessment. It uses short, engaging tasks to objectively measure areas like attention, memory, and reasoning — giving us real data to guide diagnosis and care.

What does the test actually involve?

You complete a series of short, game-like tasks on a screen — think puzzles rather than a stressful exam. It’s self-administered, so you can do it comfortably at your own pace.

How long does it take?

It’s a handful of brief tasks that most people finish comfortably in a single sitting. We’ll let you know what to expect for your specific assessment.

Is Creyos only for ADHD?

No. While it’s a powerful tool for ADHD evaluation, Creyos also helps establish a cognitive baseline, track brain health over time, and understand how thinking connects with mood and mental health.

Is my information private?

Yes. Creyos is a HIPAA-compliant platform, so your health information is kept secure and protected throughout the process.

Do you accept insurance?

We accept most major insurance plans. During your consultation, we’ll help you verify your specific benefits for evaluation and testing.
