What is the recommended test or check for Attention Deficit Hyperactivity Disorder (ADHD)?

Recommended Tests and Checks for ADHD Diagnosis

A comprehensive clinical assessment using DSM-5 criteria and standardized rating scales from multiple informants across different settings is the recommended approach for diagnosing ADHD. 1

Diagnostic Assessment Components

Core Diagnostic Elements

• DSM-5 Criteria Assessment:

  • Symptoms must be present for at least 6 months
  • Symptoms must cause significant impairment in at least two major settings (social, academic, or occupational)
  • Symptoms must be developmentally inappropriate
  • Some symptoms must have been present before age 12 1

• Standardized Rating Scales completed by:

  • Parents/caregivers
  • Teachers
  • Other adults who regularly interact with the individual 1

ADHD Presentation Criteria

To diagnose specific ADHD presentations, the following criteria must be met:

Presentation	Required Symptoms	Evidence of Impairment
Inattentive	≥6 inattention symptoms, <6 hyperactivity/impulsivity symptoms	Yes
Hyperactive/Impulsive	<6 inattention symptoms, ≥6 hyperactivity/impulsivity symptoms	Yes
Combined	≥6 inattention symptoms, ≥6 hyperactivity/impulsivity symptoms	Yes

Comprehensive Assessment Process

1. Clinical Interview with patient and family to assess:

   • Developmental history
   • Symptom onset, duration, and severity
   • Academic/occupational performance
   • Social functioning
   • Family history 1, 2

2. Medical Evaluation:

   • Physical examination
   • Vision and hearing screening
   • Assessment for other medical conditions that may mimic ADHD 2, 3

3. Screening for Comorbidities:

   • Anxiety disorders
   • Mood disorders
   • Learning disabilities
   • Substance use disorders (especially in adolescents)
   • Other psychiatric conditions 1, 2

4. Educational/Occupational Assessment:

   • School/work performance records
   • Academic achievement testing when indicated
   • Evaluation of educational accommodations needed 1

Important Considerations and Pitfalls

• There is no single, diagnostically definitive test for ADHD; diagnosis relies on comprehensive clinical assessment 4
• ADHD is often comorbid with other conditions that must be identified and addressed 2, 5
• Adult ADHD assessment requires additional considerations:
  • Evidence of childhood symptom onset
  • Adaptation of diagnostic criteria to adult presentation
  • Collateral information from family members about childhood behaviors 5, 6
• Avoid focusing solely on hyperactivity symptoms, especially in older children, adolescents, and adults where inattention may be more prominent 1
• Regular follow-up is essential to reassess symptoms, treatment effectiveness, and potential comorbidities 2

Special Considerations by Age Group

• Preschool Children (4-5 years):

  • More emphasis on behavioral observation
  • Parent/teacher reports particularly important 1, 2

• School-Age Children (6-11 years):

  • Full DSM-5 criteria application
  • Multiple informant reports (parents and teachers) 1

• Adolescents (12-17 years):

  • Self-report becomes more valuable
  • Additional screening for substance use and mood disorders 1

• Adults:

  • Adapted symptom assessment
  • Retrospective childhood symptom evaluation
  • Work performance and relationship impact assessment 5, 6

The diagnostic process should be thorough and systematic, as misdiagnosis can lead to inappropriate treatment or missed opportunities for intervention in this chronic neurodevelopmental condition that affects 8.4% of U.S. children 2.
