At-Home Cognitive Tests Guide
Humanic Blue’s Longevity365 guide: A memory task and an Alzheimer’s blood marker are different kinds of information. This guide separates online cognitive assessments, provider-run platforms and one specific blood assay.
Explore the productsLiving longer and better includes understanding changes in thinking. A score can describe task performance without explaining why it changed.
01 / Our approach
How did we evaluate these products and services?
We compared task versus blood-test format, current platform names, access and interpretation. Remote administration does not mean a test is a standalone consumer diagnosis.
At-Home Cognitive Tests: evidence and sources02 / The takeaways
What did the source evidence show?
- BrainCheck Assess and Creyos are provider-oriented platforms; Creyos was formerly Cambridge Brain Sciences.
- CogniFit offers game-like tasks with a cognitive profile.
- Quest’s amyloid ratio is a blood biomarker, not a memory test; current clinician access is distinct from the older retail listing.
What might affect task performance besides a change in memory?
The products and services
What is distinct about each product or service?
The order is not a ranking. The profiles explain what each named offering provides and how it is accessed.
The matrix compares the named formats and access arrangements, rather than awarding a clinical winner.
Product 01 / 04
BrainCheck Assess — current platform
Service or device formatProvider assessment, in clinic or remotely
BrainCheck describes a roughly fifteen-minute digital assessment covering memory, attention, processing speed and the ability to switch or manage tasks. A provider can administer it in clinic or remotely.
Assess is the current flagship name; older material may call the product BrainCheck Memory. Results support clinical assessment and monitoring rather than a standalone home diagnosis.
Product 02 / 04
CogniFit General Cognitive Assessment
Service or device formatOnline questionnaire and game-like tasks
CogniFit describes a thirty-to-forty-minute assessment of memory, attention, perception, coordination and skills used to plan or manage tasks. It generates a profile compared with demographic peers, with personal, family and professional account routes.
The company says the assessment does not provide a medical diagnosis or disease treatment. A profile may support a conversation about whether further evaluation is needed.
Product 03 / 04
Creyos — formerly Cambridge Brain Sciences
Service or device formatHealthcare and research platform
Creyos combines online cognitive tasks, behavioral questionnaires and reports. Its task groups include short-term memory, reasoning, concentration and verbal ability, with healthcare-practice and research routes.
The former Cambridge Brain Sciences address now leads to Creyos. This describes the current provider platform; it is not confirmation that an older direct-consumer package remains on sale.
Product 04 / 04
Quest AD-Detect Beta-Amyloid 42/40 Ratio, Plasma
Service or device formatClinician laboratory assay; code 11786
Quest’s clinician portfolio lists this blood test for the ratio of two forms of beta-amyloid protein, a marker associated with Alzheimer’s-related amyloid changes. It does not directly test memory.
This is the specific ratio assay, not Quest’s newer combined or p-tau217 tests. The clinician offering is listed; the older Quest Health retail route does not establish a current consumer purchase or at-home collection option. The result needs interpretation alongside clinical assessment.
How would a blood biomarker answer a different question from a thinking task?
Reader Questions
