Key Takeaways

  • Cambridge Brain Sciences is now Creyos: the same company and the same research-based tasks under a new name, announced in a post dated November 2, 2022.
  • The tasks trace back to neuroscientist Adrian Owen’s research and to large online studies such as a 2012 Neuron paper on the structure of intelligence.
  • The free public tests are gone. The old cambridgebrainsciences.com address now forwards to creyos.com, and patients take Creyos only through a clinician.
  • For patients, the important things did not change: it measures thinking skills against people your age and does not diagnose any condition.

Cambridge Brain Sciences is now Creyos. The company announced the new name in a blog post dated November 2, 2022, explaining that the change reflected a shift from serving academic researchers to serving healthcare providers. The cognitive tasks themselves come from the same line of research, and some kept their names while others were renamed. If you remember taking “the Cambridge brain test” online years ago, or your clinician has just sent you a Creyos link, this page explains how the two connect, what happened to the free public version, and what the rename does and doesn’t mean for you.

Same company, new name

What Creyos can and can’t do

It can

  • Measure memory, attention, reasoning and verbal skills with short computer tasks
  • Compare your scores with people your age
  • Give your clinician one more piece of information for an evaluation

It can’t

  • Diagnose ADHD, depression, dementia or any other condition
  • Be taken on your own as a consumer “brain test” anymore
  • Replace a clinical evaluation or full neuropsychological testing

Creyos describes itself as a web-based platform that pairs digitized cognitive tasks with standard health questionnaires for clinicians (the Creyos cognitive assessment guide covers how it works in detail). What matters here is continuity: the business behind it was, and legally still is, the same organization. Its FDA registration lists the company as “Cambridge Brain Sciences Inc. (o/a Creyos)”, where “o/a” means “operating as”. The headquarters is in Toronto, Canada.

According to the rebrand post, the name blends the ideas of “credibility” and “ethos.” The post says the name change came first, and a redesigned interface and further platform updates followed. So if a screen looks different from what you remember, that is the redesign, not a different test.

Where the tasks came from: the Owen and Hampshire research

The tasks grew out of the work of Adrian Owen, a cognitive neuroscientist who did research in Cambridge, England, and later moved to Western University in Canada. Creyos lists him as its Chief Scientific Officer and says he originated the digitized tasks. That is where the “Cambridge” in the old name came from.

Two papers from that group explain a lot about the platform:

The 2012 study focused on ages 12 to 70. Creyos says data were added later so that scores are now age-normed from age 6, and its current comparison group is more than 85,000 people. Those people volunteered online and were not screened for health conditions, which is one reason a score is a comparison, not a verdict. Our page on how accurate Creyos is looks at the strengths and limits of that evidence.

Why the founding dates don’t match

If you look up when the company started, you may find three different years, all from Creyos itself:

YearWhat Creyos says happenedWhere it says so
2009Cambridge Brain Sciences launched as a web-based platform for members of the publicRebrand blog post; about-page timeline (“the tests were moved online”)
2014“The company you know today began,” when Owen partnered with Marc Lipton, now CEORebrand blog post
2015Owen and Lipton built the team that turned the tasks into a platformAbout-page timeline
2022Renamed from Cambridge Brain Sciences to CreyosRebrand post (November 2, 2022) and about page

These don’t really contradict each other. They describe different milestones: a public research website, then a company, then a clinical product. The simplest accurate summary is that Creyos was originally launched as Cambridge Brain Sciences and renamed in 2022.

What happened to the free Cambridge Brain Sciences tests?

For years, anyone could visit the Cambridge Brain Sciences website and try the tasks, and many people did, which is how the research studies reached such large numbers. That public version is gone. Typing cambridgebrainsciences.com now lands you on creyos.com, and Creyos does not offer a consumer self-test. A patient takes Creyos only through a clinician, either from a link the clinician sends or in the clinic.

If what you want is a quick way to check your own thinking at home, our guide to free online cognitive tests explains what the remaining public options can and can’t tell you.

Creyos Health and Creyos Research

The company now runs two products. Creyos Health is the clinical version used by healthcare providers: patients complete tasks and questionnaires, and the clinician gets a report. Creyos Research serves academic and commercial studies and gives researchers access to raw data. Creyos’s researcher pages still say “formerly Cambridge Brain Sciences” for continuity with the papers that used the old name.

The two share the tasks but serve different purposes. A study volunteer and a patient might see similar screens. Only the clinical version produces a report for a clinician to interpret with you.

What did not change for patients

A new name doesn’t change what a cognitive test can and can’t do. These points still hold:

What did change is mostly behind the scenes: a redesigned interface, health questionnaires added to the platform (Creyos’s timeline says questionnaires arrived in 2017), and protocols built around specific clinical questions, such as the one used alongside an adult ADHD evaluation.

If your clinician uses Creyos

Willow & Stone offers Creyos as part of a clinical evaluation, and Dr. Stacey Forbes, a board-certified psychiatric nurse practitioner, reviews the results with you. The results add to the conversation; they don’t make the decision.

Details such as the fee, whether it’s part of your evaluation, and whether you take it at home or in the Arlington office are confirmed when you book. Ask our team through the consultation page, and see our pricing for the visit fees that are already public.

Common Questions

Is Cambridge Brain Sciences the same as Creyos?

Yes. Cambridge Brain Sciences renamed itself Creyos in 2022; the rebrand post is dated November 2, 2022. The legal entity is still listed as Cambridge Brain Sciences Inc., operating as Creyos, and the tasks come from the same research.

Can I still take the Cambridge Brain Sciences test for free?

No. The old public website now forwards to creyos.com, and Creyos does not offer a consumer self-test. Patients take it through a clinician, from a link they send or in the clinic. See our guide to free online cognitive tests for other options and their limits.

Where do I log in to Cambridge Brain Sciences now?

There is no public Cambridge Brain Sciences login anymore. If a clinician has asked you to complete Creyos, use the link they sent you. This website is not the Creyos login, so contact your clinician’s office if the link has expired or won’t open.

Who created the Cambridge Brain Sciences tests?

The tasks came out of neuroscientist Adrian Owen’s research, first in Cambridge, England, and later at Western University in Canada. Owen is Creyos’s Chief Scientific Officer. Large online studies, including a 2012 Neuron paper led by Hampshire, built the normative data.

Did the tests change when the name changed?

The interface was redesigned and the platform added questionnaires and condition-focused protocols, and some tasks have new names (Number Ladder was formerly Monkey Ladder). The tasks still measure memory, reasoning, concentration and verbal skills against people your age.

Now that clinicians use it, can a Creyos result give a diagnosis?

No. It is registered with the FDA as a Class II, 510(k)-exempt cognitive assessment aid, not cleared or approved, and it does not diagnose any condition. A clinician combines the scores with your history, symptoms and other information.
