Diagnosis is not a simple clinical intuition: it relies on standardized, scientifically validated instruments that measure specific cognitive and behavioral dimensions. Understanding these tools \u2014 what they measure, their strengths and limitations \u2014 helps concerned parents and adults navigate the often long and costly diagnostic journey and make the most of it.\n    <\/div>\n<div class=\"stats-grid\">\n<div class=\"stat-card\">\n            <span class=\"stat-number\">FREE<\/span><\/p>\n<div class=\"stat-label\">\u2014 DYNSEO screening tests, available immediately online<\/div>\n<\/p><\/div>\n<div class=\"stat-card\">\n            <span class=\"stat-number\">400\u2013800\u20ac<\/span><\/p>\n<div class=\"stat-label\">cost of a complete ADHD neuropsychological assessment in practice<\/div>\n<\/p><\/div>\n<div class=\"stat-card\">\n            <span class=\"stat-number\">500\u20131500\u20ac<\/span><\/p>\n<div class=\"stat-label\">cost of a complete ASD assessment (ADOS-2 + ADI-R + cognitive evaluation)<\/div>\n<\/p><\/div>\n<\/p><\/div>\n<h2>1. Diagnostic Tests for ADHD<\/h2>\n<pee>The diagnosis of ADHD is based on a multidimensional evaluation that combines subjective questionnaires (what the patient and their surroundings report) and objective cognitive tests (direct measures of attention and executive capabilities). None of these tools taken in isolation is sufficient \u2014 it is their combination, interpreted in a complete clinical context, that allows for diagnosis.<\/pee>\n<h3>ADHD Screening Questionnaires<\/h3>\n<div class=\"method-card blue\">\n<div class=\"method-badge badge-blue\">\ud83d\udccb ASRS v1.1 \u2014 Adults<\/div>\n<h4>Adult ADHD Self-Report Scale (6 items, ~5 min)<\/h4>\n<pee>The ASRS is the most widely used adult ADHD screening questionnaire internationally. It was developed by the World Health Organization and includes 6 questions about symptoms of inattention and hyperactivity\/impulsivity in the past 6 months. A high score (4 responses or more in the &#8220;often&#8221; or &#8220;very often&#8221; zone) justifies a formal diagnostic consultation. It is available for free online and serves as a useful first filter before any specialized approach.<\/pee>\n    <\/div>\n<div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\ud83d\udccb Conners \u2014 Children<\/div>\n<h4>Conners Rating Scale (27 to 48 items, ~15\u201320 min)<\/h4>\n<pee>The Conners scale is the pediatric gold standard for ADHD screening. It exists in three versions: Conners-3 parents (completed by parents), Conners-3 teachers (completed by teachers), and Conners-3 self-assessment (child from 8 years old). The convergence of the three informants is particularly valuable: a child whose parents and teachers report significant symptoms has a much higher diagnostic probability than one whose symptoms appear only in a single context.<\/pee>\n    <\/div>\n<h3>Objective Cognitive Tests for ADHD<\/h3>\n<div class=\"method-card blue\">\n<div class=\"method-badge badge-blue\">\u26a1 CPT \u2014 Gold standard cognitive<\/div>\n<h4>Continuous Performance Test (15\u201320 min)<\/h4>\n<pee>The CPT is the reference cognitive tool for the assessment of ADHD. The child or adult must press a button each time a target stimulus (a specific number or letter) appears and refrain for all others. The test measures four key variables: <strong>omissions<\/strong> (missed targets = inattention), <strong>commissions<\/strong> (responses to non-targets = impulsivity), <strong>mean reaction time<\/strong> (slowed in ADHD), and <strong>reaction time variability<\/strong> (higher in ADHD \u2014 the patient is sometimes very fast, sometimes very slow, unpredictably).<\/pee>\n        <pee>DYNSEO offers two equivalents accessible for free: the <a href=\"https:\/\/www.dynseo.com\/en\/selective-attention-test\/\" target=\"_blank\"><strong>Selective Attention Test<\/strong><\/a> (ability to identify targets among distractors) and the <a href=\"https:\/\/www.dynseo.com\/en\/processing-speed-test\/\" target=\"_blank\"><strong>Processing Speed Test<\/strong><\/a> (reaction time and cognitive efficiency).<\/pee>\n    <\/div>\n<div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\ud83c\udfa8 Stroop Test<\/div>\n<h4>Stroop Color-Word Test (5 min)<\/h4>\n<pee>The Stroop Test measures <strong>inhibition<\/strong> \u2014 the ability to suppress an automatic response in favor of a controlled response. In its classic version, the patient must name the color of the ink of a color word (&#8220;RED&#8221; written in blue \u2192 respond &#8220;blue&#8221;). The conflict between the automatism of reading and the requested task generates interference that reveals the quality of frontal executive control.<\/pee>\n        <pee>In ADHD, the interference effect is often more pronounced than in the control population, reflecting the difficulty in inhibiting automatic responses. It is also a test sensitive to prefrontal lesions and cognitive aging.<\/pee>\n    <\/div>\n<div class=\"method-card yellow\">\n<div class=\"method-badge badge-yellow\">\ud83e\udde0 WISC\/WAIS<\/div>\n<h4>Comprehensive cognitive assessment (1h30\u20132h)<\/h4>\n<pee>The WISC-V (children) and WAIS-IV (adults) are the most commonly used cognitive assessment batteries. In ADHD, the typical profile shows a gap between two indices: <strong>Verbal Comprehension<\/strong> (often normal to high, reflecting actual potential) and <strong>Processing Speed<\/strong> (often low, reflecting cognitive inefficiency related to inattention). This &#8220;sawtooth&#8221; profile is revealing and guides the diagnosis.<\/pee>\n    <\/div>\n<h2>2. Diagnostic tests for autism spectrum disorder<\/h2>\n<pee>The diagnosis of autism is more complex than that of ADHD because it does not rely on direct cognitive measures but on the observation and evaluation of behaviors, communication profiles, and developmental histories. The gold standard tools for autism spectrum disorder require specifically trained professionals.<\/pee>\n<div class=\"method-card rose\">\n<div class=\"method-badge badge-rose\">\ud83c\udf1f ADOS-2 \u2014 Gold standard ASD<\/div>\n<h4>Autism Diagnostic Observation Schedule (45 min)<\/h4>\n<pee>The ADOS-2 is considered the gold standard for direct assessment of autism. It is a semi-structured observation protocol: the evaluator creates standardized social situations and observes how the patient responds \u2014 their way of establishing contact, sharing attention, using spontaneous language, and responding to attempts at interaction. The ADOS-2 includes five modules tailored to the patient&#8217;s age and language level, from non-verbal to fluent adult.<\/pee>\n        <pee>Its administration requires specific certification and several days of training. It cannot be &#8220;taken online.&#8221; It is the most significant clinical investment in the ASD assessment \u2014 and the most informative.<\/pee>\n    <\/div>\n<div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\ud83d\udcda ADI-R \u2014 Parental Interview<\/div>\n<h4>Autism Diagnostic Interview \u2014 Revised (2\u20133h)<\/h4>\n<pee>The ADI-R is a structured interview conducted with the parents or guardians of a child or adult suspected of autism. It systematically covers the developmental history from birth: language acquisition, early social interactions, repetitive behaviors, sensory peculiarities, early concerns of the parents. The ADI-R is particularly valuable for the retrospective diagnosis of adults (who have no direct memory of their early development) and for cases where the ADOS is difficult to administer.<\/pee>\n    <\/div>\n<div class=\"method-card blue\">\n<div class=\"method-badge badge-blue\">\ud83d\udccf CARS-2<\/div>\n<h4>Childhood Autism Rating Scale (15\u201330 min)<\/h4>\n<pee>The CARS-2 is a clinical assessment scale that rates 15 behaviors associated with autism on a scale of 1 to 4, based on direct observation and information obtained from parents. It is used in conjunction with the ADOS-2 and the ADI-R, and can be administered from age 2. Its advantage is its relative speed \u2014 but it is less precise for mild profiles (level 1) than the ADOS.<\/pee>\n    <\/div>\n<h2>3.

DYNSEO offers free equivalents (Selective Attention Test, ADHD Test, Processing Speed Test) for an initial assessment.<\/pee>\n    <\/div>\n<div class=\"faq-item\">\n<h4>What tests are used to diagnose autism?<\/h4>\n<pee>The gold standard combines the ADOS-2 (direct observation, 45 min) and the ADI-R (parental interview, 2-3h). The CARS-2 is used as a complement. These tests require specifically trained and certified professionals.<\/pee>\n    <\/div>\n<div class=\"faq-item\">\n<h4>How much does an ADHD or ASD diagnostic assessment cost?<\/h4>\n<pee>Complete ADHD assessment: \u20ac400 to \u20ac800. Complete ASD assessment: \u20ac500 to \u20ac1,500. Initial medical consultation: \u20ac50 to \u20ac150 (reimbursed). DYNSEO tests: completely free.<\/pee>\n    <\/div>\n<div class=\"faq-item\">\n<h4>Are DYNSEO tests reliable?<\/h4>\n<pee>DYNSEO tests are screening tools built on scientifically validated paradigms. They provide an initial objective indicator \u2014 not a medical diagnosis. They help prepare for a consultation with concrete data and objectify difficulties that can sometimes be hard to describe.<\/pee>\n    <\/div>\n<div class=\"faq-item\">\n<h4>At what age can ADHD and autism be diagnosed?<\/h4>\n<pee>ASD can be diagnosed as early as 2-3 years (M-CHAT for early screening). ADHD is generally diagnosed from age 6. Both diagnoses can be made at any age, including adulthood \u2014 many people are only diagnosed in their 30s to 50s.<\/pee>\n    <\/div>\n<div class=\"faq-item\">\n<h4>Can we take an online ASD test?<\/h4>\n<pee>There is no valid online equivalent of the ADOS-2 or the ADI-R \u2014 these tools require direct observation and a clinical interview. Screening questionnaires (like the AQ \u2014 Autism Quotient) provide an indication but do not replace formal assessment. For ADHD, DYNSEO cognitive tests are good first-level tools.<\/pee>\n    <\/div>\n<div class=\"conclusion\">\n<h2>Conclusion: the right tools for the right diagnosis<\/h2>\n<pee>The diagnosis of ADHD and ASD is a structured process that requires the right instruments, the right professionals, and the right context. Neither too quick (a rushed diagnosis can be wrong), nor too long (every year without a diagnosis is a year without appropriate support). DYNSEO tests are the first accessible, free, and immediate step in a process that deserves to go all the way to a complete clinical evaluation when the signals justify it.<\/pee>\n        <pee>Start with DYNSEO screening tests, prepare for your consultation with your results, and access specialized training to better understand and support the concerned profile.<\/pee>\n    <\/div>\n<\/div>\n<footer class=\"article-footer\">\n<h3>DYNSEO Diagnostic Tests \u2014 ADHD &amp; ASD<\/h3>\n<div class=\"footer-links\">\n        <a href=\"https:\/\/www.dynseo.com\/en\/test-adhd-evaluate-your-attention-non-medical\/\" target=\"_blank\">ADHD Test<\/a><br \/>\n        <a href=\"https:\/\/www.dynseo.com\/en\/selective-attention-test\/\" target=\"_blank\">Attention Test<\/a><br \/>\n        <a href=\"https:\/\/www.dynseo.com\/en\/concentration-and-attention-test\/\" target=\"_blank\">Concentration Test<\/a><br \/>\n        <a href=\"https:\/\/www.dynseo.com\/en\/processing-speed-test\/\" target=\"_blank\">Speed Test<\/a><br \/>\n        <a href=\"https:\/\/www.dynseo.com\/en\/our-tools\/\" target=\"_blank\">All tools<\/a>\n    <\/div>\n<\/footer>\n<\/article>\n<\/div>\n<p>[\/et_pb_code][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n<p>[et_pb_code]<script type=\"application\/ld+json\">{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Quels sont les principaux tests diagnostiques utilis\u00e9s pour le TDAH ?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Les principaux tests diagnostiques du TDAH incluent les tests CPT (Continuous Performance Test), le test de Stroop, et les \u00e9chelles de Conners.

Diagnosis is not a simple clinical intuition: it relies on standardized, scientifically validated instruments that measure specific cognitive and behavioral dimensions. Understanding these tools \u2014 what they measure, their strengths and limitations \u2014 helps concerned parents and adults navigate the often long and costly diagnostic journey and make the most of it.\n    <\/div>\n\n    <div class=\"stats-grid\">\n        <div class=\"stat-card\">\n            <span class=\"stat-number\">FREE<\/span>\n            <div class=\"stat-label\">\u2014 DYNSEO screening tests, available immediately online<\/div>\n        <\/div>\n        <div class=\"stat-card\">\n            <span class=\"stat-number\">400\u2013800\u20ac<\/span>\n            <div class=\"stat-label\">cost of a complete ADHD neuropsychological assessment in practice<\/div>\n        <\/div>\n        <div class=\"stat-card\">\n            <span class=\"stat-number\">500\u20131500\u20ac<\/span>\n            <div class=\"stat-label\">cost of a complete ASD assessment (ADOS-2 + ADI-R + cognitive evaluation)<\/div>\n        <\/div>\n    <\/div>\n\n    <h2>1. Diagnostic Tests for ADHD<\/h2>\n\n    <p>The diagnosis of ADHD is based on a multidimensional evaluation that combines subjective questionnaires (what the patient and their surroundings report) and objective cognitive tests (direct measures of attention and executive capabilities). None of these tools taken in isolation is sufficient \u2014 it is their combination, interpreted in a complete clinical context, that allows for diagnosis.<\/p>\n\n    <h3>ADHD Screening Questionnaires<\/h3>\n\n    <div class=\"method-card blue\">\n        <div class=\"method-badge badge-blue\">\ud83d\udccb ASRS v1.1 \u2014 Adults<\/div>\n        <h4>Adult ADHD Self-Report Scale (6 items, ~5 min)<\/h4>\n        <p>The ASRS is the most widely used adult ADHD screening questionnaire internationally. It was developed by the World Health Organization and includes 6 questions about symptoms of inattention and hyperactivity\/impulsivity in the past 6 months. A high score (4 responses or more in the \"often\" or \"very often\" zone) justifies a formal diagnostic consultation. It is available for free online and serves as a useful first filter before any specialized approach.<\/p>\n    <\/div>\n\n    <div class=\"method-card teal\">\n        <div class=\"method-badge badge-green\">\ud83d\udccb Conners \u2014 Children<\/div>\n        <h4>Conners Rating Scale (27 to 48 items, ~15\u201320 min)<\/h4>\n        <p>The Conners scale is the pediatric gold standard for ADHD screening. It exists in three versions: Conners-3 parents (completed by parents), Conners-3 teachers (completed by teachers), and Conners-3 self-assessment (child from 8 years old). The convergence of the three informants is particularly valuable: a child whose parents and teachers report significant symptoms has a much higher diagnostic probability than one whose symptoms appear only in a single context.<\/p>\n    <\/div>\n\n    <h3>Objective Cognitive Tests for ADHD<\/h3>\n\n    <div class=\"method-card blue\">\n<div class=\"method-badge badge-blue\">\u26a1 CPT \u2014 Gold standard cognitive<\/div>\n        <h4>Continuous Performance Test (15\u201320 min)<\/h4>\n        <p>The CPT is the reference cognitive tool for the assessment of ADHD. The child or adult must press a button each time a target stimulus (a specific number or letter) appears and refrain for all others. The test measures four key variables: <strong>omissions<\/strong> (missed targets = inattention), <strong>commissions<\/strong> (responses to non-targets = impulsivity), <strong>mean reaction time<\/strong> (slowed in ADHD), and <strong>reaction time variability<\/strong> (higher in ADHD \u2014 the patient is sometimes very fast, sometimes very slow, unpredictably).<\/p>\n        <p>DYNSEO offers two equivalents accessible for free: the <a href=\"https:\/\/www.dynseo.com\/test-dattention-selective\/\" target=\"_blank\"><strong>Selective Attention Test<\/strong><\/a> (ability to identify targets among distractors) and the <a href=\"https:\/\/www.dynseo.com\/test-de-rapidite-de-traitement\/\" target=\"_blank\"><strong>Processing Speed Test<\/strong><\/a> (reaction time and cognitive efficiency).<\/p>\n    <\/div>\n\n    <div class=\"method-card teal\">\n        <div class=\"method-badge badge-green\">\ud83c\udfa8 Stroop Test<\/div>\n        <h4>Stroop Color-Word Test (5 min)<\/h4>\n        <p>The Stroop Test measures <strong>inhibition<\/strong> \u2014 the ability to suppress an automatic response in favor of a controlled response. In its classic version, the patient must name the color of the ink of a color word (\"RED\" written in blue \u2192 respond \"blue\"). The conflict between the automatism of reading and the requested task generates interference that reveals the quality of frontal executive control.<\/p>\n        <p>In ADHD, the interference effect is often more pronounced than in the control population, reflecting the difficulty in inhibiting automatic responses. It is also a test sensitive to prefrontal lesions and cognitive aging.<\/p>\n    <\/div>\n\n    <div class=\"method-card yellow\">\n        <div class=\"method-badge badge-yellow\">\ud83e\udde0 WISC\/WAIS<\/div>\n        <h4>Comprehensive cognitive assessment (1h30\u20132h)<\/h4>\n        <p>The WISC-V (children) and WAIS-IV (adults) are the most commonly used cognitive assessment batteries. In ADHD, the typical profile shows a gap between two indices: <strong>Verbal Comprehension<\/strong> (often normal to high, reflecting actual potential) and <strong>Processing Speed<\/strong> (often low, reflecting cognitive inefficiency related to inattention). This \"sawtooth\" profile is revealing and guides the diagnosis.<\/p>\n    <\/div>\n\n    <h2>2. Diagnostic tests for autism spectrum disorder<\/h2>\n\n    <p>The diagnosis of autism is more complex than that of ADHD because it does not rely on direct cognitive measures but on the observation and evaluation of behaviors, communication profiles, and developmental histories. The gold standard tools for autism spectrum disorder require specifically trained professionals.<\/p>\n\n    <div class=\"method-card rose\">\n        <div class=\"method-badge badge-rose\">\ud83c\udf1f ADOS-2 \u2014 Gold standard ASD<\/div>\n        <h4>Autism Diagnostic Observation Schedule (45 min)<\/h4>\n        <p>The ADOS-2 is considered the gold standard for direct assessment of autism. It is a semi-structured observation protocol: the evaluator creates standardized social situations and observes how the patient responds \u2014 their way of establishing contact, sharing attention, using spontaneous language, and responding to attempts at interaction. The ADOS-2 includes five modules tailored to the patient's age and language level, from non-verbal to fluent adult.<\/p>\n        <p>Its administration requires specific certification and several days of training. It cannot be \"taken online.\" It is the most significant clinical investment in the ASD assessment \u2014 and the most informative.<\/p>\n    <\/div>\n\n    <div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\ud83d\udcda ADI-R \u2014 Parental Interview<\/div>\n        <h4>Autism Diagnostic Interview \u2014 Revised (2\u20133h)<\/h4>\n        <p>The ADI-R is a structured interview conducted with the parents or guardians of a child or adult suspected of autism. It systematically covers the developmental history from birth: language acquisition, early social interactions, repetitive behaviors, sensory peculiarities, early concerns of the parents. The ADI-R is particularly valuable for the retrospective diagnosis of adults (who have no direct memory of their early development) and for cases where the ADOS is difficult to administer.<\/p>\n    <\/div>\n\n    <div class=\"method-card blue\">\n        <div class=\"method-badge badge-blue\">\ud83d\udccf CARS-2<\/div>\n        <h4>Childhood Autism Rating Scale (15\u201330 min)<\/h4>\n        <p>The CARS-2 is a clinical assessment scale that rates 15 behaviors associated with autism on a scale of 1 to 4, based on direct observation and information obtained from parents. It is used in conjunction with the ADOS-2 and the ADI-R, and can be administered from age 2. Its advantage is its relative speed \u2014 but it is less precise for mild profiles (level 1) than the ADOS.<\/p>\n    <\/div>\n\n    <h2>3.

Screening questionnaires (like the AQ \u2014 Autism Quotient) provide an indication but do not replace formal assessment. For ADHD, DYNSEO cognitive tests are good first-level tools.<\/p>\n    <\/div>\n\n    <div class=\"conclusion\">\n        <h2>Conclusion: the right tools for the right diagnosis<\/h2>\n        <p>The diagnosis of ADHD and ASD is a structured process that requires the right instruments, the right professionals, and the right context. Neither too quick (a rushed diagnosis can be wrong), nor too long (every year without a diagnosis is a year without appropriate support). DYNSEO tests are the first accessible, free, and immediate step in a process that deserves to go all the way to a complete clinical evaluation when the signals justify it.<\/p>\n        <p>Start with DYNSEO screening tests, prepare for your consultation with your results, and access specialized training to better understand and support the concerned profile.<\/p>\n    <\/div>\n\n<\/div>\n\n<footer class=\"article-footer\">\n    <h3>DYNSEO Diagnostic Tests \u2014 ADHD &amp; ASD<\/h3>\n    <div class=\"footer-links\">\n        <a href=\"https:\/\/www.dynseo.com\/test-tdah-evaluez-votre-attention-non-medical\/\" target=\"_blank\">ADHD Test<\/a>\n        <a href=\"https:\/\/www.dynseo.com\/test-dattention-selective\/\" target=\"_blank\">Attention Test<\/a>\n        <a href=\"https:\/\/www.dynseo.com\/test-concentration-attention\/\" target=\"_blank\">Concentration Test<\/a>\n        <a href=\"https:\/\/www.dynseo.com\/test-de-rapidite-de-traitement\/\" target=\"_blank\">Speed Test<\/a>\n        <a href=\"https:\/\/www.dynseo.com\/nos-outils\/\" target=\"_blank\">All tools<\/a>\n    <\/div>\n<\/footer>\n<\/article>\n<\/div>[\/et_pb_code][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n\n[et_pb_code]<script type=\"application\/ld+json\">{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Quels sont les principaux tests diagnostiques utilis\u00e9s pour le TDAH ?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Les principaux tests diagnostiques du TDAH incluent les tests CPT (Continuous Performance Test), le test de Stroop, et les \u00e9chelles de Conners.
