Cognitive ADHD Testing with Creyos

Neurodiversity-Affirming Care Designed for Real Life

ADHD is not only about attention or impulsivity. For many adults, the greatest challenges lie in executive functioning: how the brain plans, organizes, remembers, shifts focus, and manages cognitive effort.

At Neurokin, we use Creyos, an evidence-based cognitive assessment platform, to support a deeper, more nuanced understanding of ADHD as part of a comprehensive, neurodiversity-affirming evaluation.

Creyos does not diagnose ADHD on its own. It provides objective cognitive data that, when interpreted alongside clinical interviews and your lived experience, helps us understand how your brain actually works. The goal is clarity, not a label.

What Is Creyos?

Creyos is a scientifically validated, computerized cognitive assessment platform used in clinical and research settings worldwide.

Rather than relying on subjective impressions alone, Creyos measures cognitive performance across domains commonly affected in ADHD.


It offers objective insight into how the brain processes information in real time, providing quantifiable data that supports clinical understanding.

Creyos is not a checklist or a symptom inventory. It is a performance-based assessment that captures how your brain handles specific cognitive tasks under standardized conditions.


This kind of data can be especially valuable when ADHD symptoms are subtle, complex, or have been masked for years.

What Creyos Measures in ADHD Evaluations

Creyos assesses several core cognitive domains, including:

Working Memory

How well you hold and manipulate information in your mind over short periods. Working memory challenges often show up as forgetting what you were about to do, losing track of conversations, or struggling to follow multi-step instructions.

Attention and Sustained Focus

Your ability to maintain focus over time and resist distraction. This is often where ADHD-related patterns become measurable, especially under conditions that require sustained mental effort.

Processing Speed

How quickly you take in and respond to information. Slower processing speed can contribute to feeling overwhelmed, needing extra time to complete tasks, or struggling in fast-paced environments.

Response Inhibition

Your ability to stop or delay an automatic response. Challenges here can show up as impulsivity, interrupting others, or acting before thinking through consequences.

Cognitive Flexibility and
Executive Control

How easily you shift between tasks, adapt to changing demands, and manage competing priorities. Difficulty here often explains why transitions feel hard or why switching focus takes so much effort.

These domains often explain real-world challenges such as mental fatigue, difficulty prioritizing, task initiation struggles, and inconsistent performance across different contexts.

Why Neurokin Uses Cognitive ADHD Testing

Cognitive data adds clarity when used thoughtfully.
Creyos supports ADHD evaluation by helping clinicians:

Differentiate ADHD-related cognitive patterns

from anxiety, burnout, or stress

Many conditions can cause focus and memory challenges. Objective cognitive testing helps clarify whether the patterns you experience are consistent with ADHD or better explained by something else.

Understand how executive function challenges

show up beneath surface behaviors

You may have developed strong compensatory strategies that mask underlying cognitive differences. Creyos can help reveal what is happening at a cognitive level, even when outward performance looks "fine."

Validate lived experience with

objective data

For adults who have been dismissed or told they are "too successful" to have ADHD, cognitive testing can provide concrete evidence that supports what you have always known about how your brain works.

Inform personalized treatment
and support strategies

Understanding your specific cognitive profile helps us build a treatment plan that addresses your actual challenges, not generic ADHD advice.

At Neurokin, cognitive testing never replaces clinical understanding. It enhances it.

How Creyos Fits Into Neurokin's ADHD Evaluation Process

Context matters. Cognitive testing is most useful when it is interpreted alongside other sources of information.

This integrated approach ensures that cognitive data is meaningful, humane, and actionable. We do not reduce you to a set of scores.


We use data to better understand how your brain works and what kind of support will actually help.

When clinically appropriate, Creyos results are interpreted alongside:

Blue rounded-square app icon with a small teal chat bubble and a simple face

Comprehensive clinical interviews

Purple rounded-square icon with an upward arrow inside an arch shape

Developmental and personal history

Self-report questionnaires and rating scales

Contextual review of how symptoms affect work, relationships, and daily life

Neurodiversity-Affirming Use of Cognitive Testing

Objective cognitive testing should never invalidate lived experience.

At Neurokin, Creyos is used within a neurodiversity-affirming,
strengths-based framework that recognizes cognitive differences as variations, not deficits.

We do not use cognitive testing to prove you are "broken" or to gatekeep diagnosis. We use it to understand your brain better, to provide language for patterns you may have noticed for years, and to inform support strategies that actually fit how you think.

If your scores are "normal" but your life experience says otherwise, we take that seriously. Cognitive testing is one data point. Your experience is the full picture.

Your Questions About Cognitive ADHD Testing, Answered

  • What is Creyos?

    Creyos is a scientifically validated cognitive assessment platform that measures performance across multiple domains, including working memory, attention, processing speed, response inhibition, and cognitive flexibility. It is used in clinical and research settings worldwide. At Neurokin, we use Creyos as part of comprehensive ADHD evaluations when additional cognitive data would be valuable.

  • What does Creyos measure?

    Creyos measures cognitive performance in areas commonly affected by ADHD: working memory (holding and manipulating information), sustained attention (maintaining focus over time), processing speed (how quickly you take in information), response inhibition (stopping automatic responses), and cognitive flexibility (shifting between tasks). These measurements help us understand how your brain handles specific cognitive demands.

  • Is Creyos the same as an IQ test?

    No. Creyos is not an IQ test and does not measure intelligence in the traditional sense. It measures specific cognitive functions that are relevant to understanding ADHD and executive function challenges. Your Creyos results do not define your intelligence, potential, or worth. They provide data about how your brain processes certain types of information.

  • Can Creyos diagnose ADHD?

    No. Creyos does not diagnose ADHD on its own. It provides objective cognitive data that supports clinical judgment when interpreted alongside clinical interviews, personal history, and other assessment tools. ADHD diagnosis is a clinical process that considers the full picture of your experience, not just test scores.

  • Do I need Creyos testing for my ADHD evaluation?

    Not necessarily. Creyos is used when clinically appropriate, not routinely for every patient. It may be especially helpful when symptoms are complex, when there is overlap with other conditions, or when additional data would clarify the diagnostic picture. During your evaluation, we will discuss whether cognitive testing makes sense for your situation.

  • How long does Creyos testing take?

    A typical Creyos assessment takes approximately 30 to 45 minutes, depending on which cognitive tasks are included. The assessment is completed on a computer or tablet and involves a series of interactive tasks designed to measure specific cognitive functions.

  • What happens with my Creyos results?

    Your Creyos results are reviewed by your clinician and interpreted in the context of your full evaluation. During your feedback session, we will explain what the results mean, how they relate to your symptoms and lived experience, and what they suggest about support strategies that might help. You will receive a clear explanation, not just numbers.

  • Can Creyos results be "wrong"?

    Creyos results reflect your performance on specific cognitive tasks under standardized conditions. Many factors can influence performance, including fatigue, stress, medication, or testing environment. If your results do not match your lived experience, that is important information. We take your experience seriously and do not dismiss what you know about yourself based on a single data point.

  • Is cognitive testing covered by insurance?

    Neurokin operates on a private-pay model. Cognitive testing with Creyos is included as part of comprehensive ADHD evaluations when clinically indicated. We can provide documentation to support out-of-network reimbursement if your insurance plan offers that option.

  • How is Creyos different from Qb Check?

    Creyos and Qb Check measure different things. Qb Check is an objective ADHD test that specifically measures attention and impulse control through a continuous performance task. Creyos is a broader cognitive assessment that measures multiple domains, including working memory, processing speed, and cognitive flexibility. Depending on your evaluation needs, we may use one or both tools to build a complete picture of your cognitive functioning.
