What's New on ADHD PREP: Your Complete Pre-Diagnosis Toolkit

Building the pre-diagnosis platform we wished existed

When we started ADHD PREP, the goal was simple: help people who suspect they might have ADHD prepare for a clinical assessment. Too many people walked into their appointments with vague memories and scattered anecdotes, only to leave feeling unheard or dismissed.

Over the past year, we have built something much bigger than a screening tool. ADHD PREP is now the most comprehensive free ADHD pre-diagnosis platform available anywhere. Whether you are just starting to wonder if you might have ADHD or you are months into waiting for an assessment, we have built the tools you need to prepare properly.

This is not diagnosis. We do not replace clinicians. But we do help you arrive at your appointment with structured data, clear documentation, and the confidence that comes from being genuinely prepared.

Cognitive tests: Objective performance data, completely free

One of the most significant additions to ADHD PREP is our cognitive testing suite. Unlike self-report questionnaires that ask you to reflect on your symptoms, cognitive tests measure your brain's actual performance in real-time.

Go/No-Go Task: This test measures response inhibition and impulse control. You see green circles (press the spacebar) and red squares (do not press). About 80% of trials are go trials, creating a strong automatic response that you then need to inhibit on no-go trials. The test measures commission errors (pressing when you should not), reaction time variability, and overall accuracy.

CPT-Lite (Continuous Performance Test): This test measures sustained attention and vigilance. Letters appear on screen one at a time, and you press the spacebar only when you see the letter X. It sounds simple, but maintaining steady attention for five to seven minutes is where ADHD-related deficits become visible. The test measures omission errors (missing targets), reaction time variability, and performance decrement over time.

Both tests are completely free, no account required, and your results are saved locally alongside your screener results. The cognitive tests page at /cognitive gives you access to both tests with detailed instructions and comprehensive results including an ADHD Risk Index based on clinical norms.

Why does this matter? Self-report screeners measure your awareness of symptoms. Cognitive tests measure what your brain actually does under controlled conditions. Together, they provide a more complete picture than either alone.

Symptom Journal: Track patterns over time

Clinicians care about patterns. They want to know if your symptoms are consistent across contexts and stable over time. But if you are like most people, your memory of how you felt last week, last month, or last year is unreliable.

The Symptom Journal is designed to solve this problem. It lets you track your symptoms over time and make notes about the past—both for current documentation and retrospective entries about patterns you remember.

Each entry captures: - Date (current or backdated for historical notes) - Symptom severity across multiple dimensions - Context like sleep quality, stress levels, and environment - Triggers you noticed - Notes for anything else relevant

The journal is completely isolated from your assessment results and interview data. It is a separate tool designed specifically for symptom documentation, and all data stays on your device.

Why does this matter? When you walk into your clinical assessment with a journal showing consistent symptom patterns over weeks or months, you are providing exactly the kind of longitudinal evidence clinicians need. You are no longer relying on your unreliable memory—you have documentation.

Longitudinal Analytics: See patterns, not just moments

Every time you complete a screener or cognitive test on ADHD PREP, your result is automatically saved, timestamped, and compared to your previous results. Over time, this builds a longitudinal dataset that shows patterns a single test could never reveal.

The analytics dashboard at /results/analytics shows you:

Consistency: How stable are your scores across multiple tests? ADHD symptoms are typically consistent. High consistency strengthens your case. Wild fluctuations might suggest situational factors or other conditions.

Trends: Are your scores stable, improving, or worsening? Small changes matter. A gradual improvement might mean your coping strategies are working. An upward trend might indicate increasing stress or symptoms.

Category breakdown: Where do your high scores cluster? ADHD PREP groups results into ADHD Screeners, Executive Function, Functional Impairment, and Related Conditions (anxiety, depression, autism overlap). Seeing which categories are elevated helps paint a fuller picture.

Frequency: How often are you testing? The dashboard tracks your testing patterns and helps you understand the reliability of your data.

This is the same kind of longitudinal analysis that happens in research studies and specialized clinics. We have made it accessible to everyone, for free, with no account required.

ADHD Glossary: 95+ terms explained clearly

ADHD comes with its own language. Executive function. Comorbidity. Rejection sensitive dysphoria. Time blindness. If you do not understand these terms, you cannot fully participate in conversations about your own brain.

Our ADHD Glossary now includes over 95 terms with clear, accessible definitions. The glossary is organized into categories:

Medical Terms: ADHD subtypes, DSM-5 criteria, neurodevelopmental disorder classifications, dopamine, norepinephrine, and more.

Psychological Terms: Executive function, working memory, emotional dysregulation, hyperfocus, masking, rejection sensitive dysphoria, and more.

Treatment Terms: Stimulant and non-stimulant medications, CBT, behavioral therapy, executive function coaching, neurofeedback, and more.

Educational Terms: IEP, 504 Plan, accommodations, and related concepts.

General Terms: Neurodiversity, functional impairment, and broader concepts.

The glossary includes interactive search and category filtering, making it easy to find exactly what you need. Whether you are trying to understand your screening results, prepare for an appointment, or just learn more about ADHD, the glossary is your reference guide.

15 Country diagnosis guides: Navigate your local system

ADHD diagnosis looks different in every country. Costs, wait times, referral processes, and available pathways vary dramatically. What works in the US does not apply in the UK. What is available in Australia is different from what exists in Germany.

Our country-specific diagnosis guides cover 15 countries and regions:

North America: United States, Canada

Europe: United Kingdom, Ireland, Germany, France, Netherlands, Spain, Sweden

Asia-Pacific: Australia, New Zealand, Singapore, Hong Kong, China

Other Regions: South Africa

Each guide includes: - Step-by-step diagnosis pathways - Public vs. private options - Typical costs and wait times - Referral processes - Region-specific screeners and criteria (DSM-5, ICD-11, CCMD-3) - Tips for navigating the local healthcare system

The Full Mock ADHD Assessment & Interview also adapts to your region, using region-specific diagnostic frameworks and recommending appropriate screeners based on where you are seeking diagnosis.

Full Mock ADHD Assessment & Interview: AI-powered interview preparation

The Full Mock ADHD Assessment & Interview is our premium feature designed to help you feel calm and prepared for your ADHD appointment. It is a structured, AI-powered interview simulation that helps you:

Identify gaps in your history: The session asks clinician-style questions about symptoms across different life domains—work, relationships, education, daily functioning. It helps you think through experiences you might not have considered relevant.

Complete relevant screeners: During the session, the AI can invoke cognitive tests and comorbidity screeners (GAD-7, PHQ-9, etc.) based on what you share. If you mention anxiety symptoms, it might suggest the GAD-7. If you describe executive function struggles, it might offer a cognitive test.

Generate a comprehensive report: At the end of the session, you receive a detailed PDF report that summarizes your interview, includes all screener and cognitive test results, and provides structured information you can bring to your clinical appointment.

Region-specific adaptation: The session adapts to your region, using DSM-5 structure for Western countries, CCMD-3 for China, and adapted frameworks for other Asian regions.

The Full Mock ADHD Assessment & Interview is not diagnosis. It is preparation. It helps you organize your thoughts, document your experiences, and arrive at your clinical appointment with structured evidence rather than scattered anecdotes.

Everything stays on your device

Privacy is not an afterthought. Every feature on ADHD PREP is designed with privacy as a core principle.

All your data—screener results, cognitive test results, symptom journal entries, interview transcripts—is stored locally in your browser. We do not require accounts. We do not collect email addresses. We do not track your assessment history on our servers.

Your data stays on your device, under your control. You can export it, share it with clinicians, or keep it completely private. When you clear your browser data, your ADHD PREP data is cleared too.

This approach means you can use ADHD PREP without worrying about data breaches, privacy policies, or your sensitive health information being stored on servers somewhere. It is your data, on your device, for your use.

What's next for ADHD PREP

We are continuing to build and improve. Some things we are working on:

More cognitive tests: Expanding the cognitive testing suite with additional executive function assessments.

Enhanced analytics: Deeper insights and visualizations for your longitudinal data.

More country guides: Expanding coverage to additional countries and regions.

Community resources: Connecting users with support groups, advocacy organizations, and educational resources in their area.

Our mission remains the same: help people who suspect they might have ADHD prepare for clinical assessment. We believe everyone deserves access to quality pre-diagnosis tools, regardless of their location or financial situation. Everything we build is designed to make the path from "I think I might have ADHD" to "Here is my comprehensive documentation" as clear and accessible as possible.

Important disclaimer

ADHD PREP provides educational and screening tools to help you prepare for clinical assessment. We do not diagnose ADHD or any other condition. ADHD diagnosis requires a comprehensive clinical evaluation by a licensed professional who considers symptoms, history, impairment, and multiple sources of information. Screening tools and cognitive tests measure symptoms and performance metrics that are associated with ADHD, but they cannot replace professional evaluation. If you have concerns about ADHD or any other health condition, please consult a clinician who can assess your individual situation and provide personalized care.
