ADHD diagnosis (adult)

Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders, but it remains significantly underdiagnosed in adults — especially in women. Many adults with ADHD were never diagnosed as children because their symptoms were attributed to laziness, anxiety, depression, or personality traits.

59 steps across 12 sections

1. Comprehensive Clinical Interview

  • Detailed questions about childhood behavior, academic history, work performance, and relationships
  • Family history of ADHD, mental health conditions, and substance use
  • Current symptoms and how they affect daily functioning
  • Medical history to rule out conditions that mimic ADHD (thyroid disorders, sleep apnea, etc.)

2. Symptom Rating Scales and Questionnaires

  • Adult ADHD Self-Report Scale (ASRS) — WHO-developed screening tool
  • Conners Adult ADHD Rating Scale (CAARS) — comprehensive symptom measure
  • Barkley Adult ADHD Rating Scale
  • Wender Utah Rating Scale — retrospective childhood symptoms
  • Questionnaires often ask about childhood experiences, current symptoms, work performance, and relationship patterns

3. Collateral Information

  • Provider may request permission to interview family members who knew you as a child
  • Spouses, partners, friends, or coworkers may provide input on current functioning
  • Old report cards or school records can document childhood symptoms

4. Screening for Co-occurring Conditions

  • Anxiety disorders (present in ~50% of adults with ADHD)
  • Bipolar disorder
  • Substance use disorders
  • Learning disabilities
  • These conditions can mimic ADHD symptoms or coexist with ADHD, making differential diagnosis critical

5. Optional Neuropsychological Testing

  • Not required for diagnosis but provides objective data on attention, memory, executive function, and processing speed
  • Helpful when the diagnosis is unclear or co-occurring learning disabilities are suspected
  • Typically 4-8 hours of testing
  • Cost: $1,500-$5,000

6. Diagnostic Criteria Check

  • Per DSM-5: at least 5 symptoms in either the inattentive or hyperactive-impulsive category, present for at least 6 months
  • Symptoms must be present in two or more settings (work, home, social)
  • Several symptoms must have been present before age 12 (though they may not have been recognized)
  • Symptoms cause clinically significant impairment in social, academic, or occupational functioning
  • Symptoms are not better explained by another mental health condition

7. Feedback Session

  • Typically 1-2 weeks after evaluation
  • Receive diagnosis (or explanation of alternative findings)
  • Discuss treatment recommendations
  • Entire process takes 2-6 hours of evaluation time spread across 1-3 appointments

8. Inattentive Type (formerly ADD)

  • Difficulty sustaining attention on tasks or conversations
  • Frequently loses or misplaces things (keys, phone, documents)
  • Trouble organizing tasks and managing multi-step projects
  • Difficulty following through on instructions or finishing tasks
  • Easily distracted by unrelated thoughts or stimuli
  • Forgetful in daily activities (missing appointments, forgetting bills)
  • Avoids tasks requiring sustained mental effort (paperwork, forms)
  • Makes careless mistakes in work or other activities

9. Hyperactive-Impulsive Type

  • Fidgeting, tapping, or restlessness (in adults: internal restlessness)
  • Difficulty staying seated in situations where expected
  • Talking excessively
  • Blurting out answers before questions are finished
  • Difficulty waiting turns (in conversations, lines, traffic)
  • Interrupting or intruding on others
  • Feeling driven by a motor or unable to relax

10. Combined Type

  • Meets criteria for both inattentive and hyperactive-impulsive presentations
  • Most common overall presentation in clinical settings

11. Stimulant Medications (First-Line)

  • Methylphenidate-based Ritalin, Concerta, Focalin, Daytrana (patch)
  • Amphetamine-based Adderall, Vyvanse, Dexedrine
  • Most effective treatment for ADHD symptoms; ~70-80% of adults respond well
  • Available in short-acting (4-6 hours) and extended-release (8-14 hours) formulations
  • Common side effects: decreased appetite, insomnia, dry mouth, increased heart rate
  • Requires regular follow-up and may need dose adjustments
  • DEA Schedule II: requires monthly prescriptions in most states (no refills)

12. Non-Stimulant Medications

  • Atomoxetine (Strattera) — SNRI; takes 4-6 weeks for full effect
  • Bupropion (Wellbutrin) — off-label; also treats depression
  • Guanfacine (Intuniv) and Clonidine (Kapvay) — alpha-2 agonists; often used as add-ons
  • Viloxazine (Qelbree) — newer non-stimulant approved for adults
  • Preferred when stimulants are contraindicated (heart conditions, substance use history, severe anxiety)

Common Mistakes

  • Assuming it is just anxiety or depression
  • Thinking you cannot have ADHD because you did well in school
  • Skipping the thorough evaluation
  • Not gathering childhood evidence
  • Stopping medication without medical guidance

Pro Tips

  • Before your evaluation, write a "symptom history"
  • Request your school records early
  • Ask about combined treatment from day one
  • Use your diagnosis to get workplace accommodations
  • Join CHADD or ADDA
