ADHD Talk Overview
• History• Diagnostic criteria• Epidemiology (Who has it?)• Etiology (Why do they have it?)• Making the diagnosis• Treatment
History of ADHD• Sir George Still first described
ADHD (1902)• Hyperkinetic Reaction (1920s)• Franklin Ebaugh evidenced that
ADHD could arise from brain injury (1923)
• 1967 Federal government funds (NIMH) first used for studying effect of stimulants on children with hyperactivity
Dole R. The history of adult attention-deficit disorder. Psychiatric Clinics of N. America 2004; 27: 203-14.
• DSM-I: Minimal brain dysfunction (1952)
• DSM-II: Hyperactive reaction of childhood (1968)
• DSM-III: ADD with or without hyperactivity (1980)
• DSM-III-R:Attention-deficit hyperactivity disorder (1987)
• DSM-IV+IV-R: Inattentive type, hyperactive-impulsive type, and combined type (1994)
History of ADHD
DSM-V Revisions to ADHD
• Same criteria as DSM-IV• Onset before age 12 (age 7 in DSM-IV)• 5 symptom criteria in adults (6 in
DSM-IV)• Removed autism-spectrum d/o from
excluders• Elaborated ADHD criteria descriptions
(more examples for adults)
2013 American Psychiatric Association. DSM-5
ADHD Diagnostic Criteria
DSM-V-, APA 2013DSM-V-, APA 2013
Inattention*• Poor attention to details• Careless mistakes• Inattention in tasks or play• Does not seem to listen when spoken to • Does not follow through on:
– Instructions– Work / Schoolwork– Chores
• Disorganized • Avoids tasks that require sustained
mental effort (procrastination)• Loses things• Easily distracted • Forgetful
DSM-V-, APA 2013DSM-V-, APA 2013
*6 inattention or hyperactivity-impulsivity criteria (5 for age 17+)
Hyperactivity-Impulsivity*
• Hyperactivity– Fidgets / Squirms in seat – Leaves seat – Runs about / climbs excessively
(restlessness in adults) – Difficulty playing quietly – “On the go" or "driven by a motor" – Talks excessively
• Impulsivity– Blurts out answers– Difficulty awaiting turn / Impatient– Interrupts or intrudes on others
DSM-V-, APA 2013DSM-V-, APA 2013
*6 inattention or hyperactivity-impulsivity criteria (5 for age 17+)
ADHD-Other Criteria
• Symptoms present before age 12 years• Impairment in 2 settings (school, work, office, home)• The symptoms do not occur exclusively during the course of a
Pervasive Developmental Disorder, Schizophrenia, or other Psychotic Disorder and are not better accounted for by another mental disorder (e.g., Mood Disorder, Anxiety Disorder, Dissociative Disorder, or Personality Disorder)
DSM-V-, APA 2013DSM-V-, APA 2013
ADHD Subtypes• Inattentive Type• Hyperactive-Impulsive Type• Combined Type• Other Specified or Unspecified ADHD
DSM-V-, APA 2013DSM-V-, APA 2013
Case Example• 16 yo girl with
worsening school performance
• Parents wonder what can help—maybe a stimulant?
• No past psych or medical issues
• Meets criteria for inattentive ADHD
• Was overweight -> Started dieting 9 mos ago -> Lost 45# to 79% IBW
• Neuropsych testing shows trouble with executive fxn, concentration, memory
• Do you prescribe a stimulant?
Epidemiology (who has it?)• 8-12% of school children worldwide• Lower prevalence noted in some studies in
other countries is criteria dependent (ICD-10 < DSM-IV)

Epidemiology (Who has it?)• More common in lower socio-
economic population• Gender ratios
– Clinical M:F = 10:1– Non-clincal M:F = 3:1– Adults M:F = 1.5:1– ADHD may be less disruptive in
women– Could be increased environmental
exposure (head injury) in males• May be under-identified and
under-treated in minority groupsBiederman J, Faraone, S. The MGH studies of gender influences on ADHD in youth and relatives. Psychiatric Clinics of N. America 2004; 27: 225-32.
Co-morbidity (other diagnoses)
• 68.2% have a co-morbid condition

Etiology (What caused it?)
• ADHD diagnosis does not imply any specific etiology
• No one theory accounts for all cases
• Most likely multi-factorial
Etiology: Biological Risk Factors
• Brain injuries• Low birth weight• Fetal alcohol exposure• Maternal smoking in
pregnancy• Lead exposure
Biederman J, Faraone S, Attention-deficit hyperactivity disorder, Lancet 2005; 366: 237-48.
Etiology: Psychosocial Risk Factors
• Marital or family discord
• Neglect/deprivation• Low socioeconomic
status• Large family size• Parental
psychopathology• Foster placement
Rutter M, Cox A, Tupling C, Berger M, Yule W. Attainment and adjustment in two geographical areas: vol 1. The prevalence of psychiatric disorders. British Journal of Psychiatry 1975; 126: 493-509.
Etiology (What caused it?)Localized brain dysfunction• Frontal-subcortical circuits
– Executive function: inhibition, working memory, set-shifting, interference control, planning, sustained attention
– Reduced volume size in these regions on structural imaging– Less activation in these areas on functional imaging
• Striatum (subcortical structure)– Many dopamine synapses– Vulnerable to perinatal hypoxia– Related to hyperactivity and impulsivity if not intact
Biederman J, Faraone S, Attention-deficit hyperactivity disorder, Lancet 2005; 366: 237-48.
Etiology (What caused it?)• Genetic factors
– Heritability: 75%– 4-5x greater probability if full sibling
has ADHD– Genes with small effect:
• Dopamine D4 + D5 receptor• Dopamine transporter SLC6A3
• Serotonin transporter SLC6A4
• Serotonin receptor HTR1B• Synaptic-vesicle transporter SNAP25
– Genes with large effect:• None
Biederman J, Faraone S, Attention-deficit hyperactivity disorder, Lancet 2005; 366: 237-48.
Etiology (What caused it?) Evolution in a complex society
Prehistoric hunter/gatherer needed impulsivity and quickly shifting attention
Genetic attraction to risk-takersOne-room schools, small classes,
individual attention, chores, tight community
Same biological capacity now overwhelmed in demanding society
Case Example• 19 yo female• College student• Trouble with school• Reports all inattentive
ADHD sxs and some impulsivity
• Tried her friend’s Ritalin which “really helped me” study
• No medical issues• No past psych treatment• No family hx of
ADHD/psych/addiction• Would you prescribe a
medicine for ADHD?
Diagnosis of ADHD• History
– Patient– Family– School/teachers– Standardize and quantify
symptoms• Connors Series• Achenbach Child
Behavior Checklist• Teacher Observation of
Classroom Adaptation (TOCA)
• Revised Behavior Problem Checklist (RBPC)-Quay
Diagnosis of ADHD
• Rule out other diagnoses– Conduct and oppositional defiant disorders– Mood disorders (depression, bipolar disorder)– Anxiety disorders (panic, OCD, generalized)– Post-traumatic stress disorder– Learning and developmental disorders– Psychosis– Parenting problems (limits, structure, consistency)– Medications (asthma, anti-seizure, other)

Diagnosis of ADHD• Tests
– Not necessary or sufficient for a diagnosis– Psychometric and neuropsychological tests for attention,
organization, impulsivity and executive function• Quotient System (Marty Teicher MD)
– 20-minute test– Measures micro-motion (head)– Analyzes impulsivity and shifts in attention– Compares to database of Normal and ADHD Controls
• Continuous Performance Test• Matching Familiar Figures• Reaction time tests• Wisconsin Card Sorting Test• Paired Associate Learning• Porteus Mazes• Stroop Color Word Test• Wechsler Intelligence Scale for Children

Untreated ADHD ComplicationsProne to accidents:
-50% bike accidents-33% ER visits-2-4x more MVA’s
Increased likelihood of:-Depressive disorders-Anxiety disorders-Alcohol and drug abuse
Poor team performanceAcademic failure and grade retentionSocial ineptness, unpopularity, and peer
rejection Missed development of life-long good
work habits and attitude

Adult ADHD• Age-dependent decline in
symptoms• People develop better
impulse control, better attention spans and more sedate habits (less hyper) as they grow older.
• Rely on history from the patient and significant others

Treatment of ADHDMedications: Stimulants
• Stimulants– Best documented efficacy in
controlled trials– Most specific for ADHD
symptoms– Linear benefit with dosage until
side effects– Fast acting and safe (although
Schedule II)– Dexedrine (dextroamphetamine)
developed in 1920s and Ritalin (methylphenidate) developed in 1950s

NIMH Multimodal Treatment of ADHD
NIMH Multimodal Treatment of ADHD: 8-year follow-up
• Functioning improved overall compared to the beginning of the study• No differences in symptoms/functioning among different assigned
treatment groups as children• ADHD Youths > non-ADHD youths
– Academic problems– Social problems– Conduct problems (including run-ins with police)– Depression– Psychiatric hospitalizations
• Best function at 8 years = responded well to treatment & maintained their gains for 2 years
• 61.5% of medicated kids stopped taking medication– Function on no meds = function of those still medicated– Raises questions about whether medication treatment beyond two years
continues to be needed by all.

Treatment of ADHDStimulants
• Side effects– Appetite loss– Sleep disturbance– Restlessness/anxiety– Cramps– Rebound/Crash
• Irritability• Depression
– Tics– Growth slowing Greenhill L, Halperin JM, Abikoff H: Stimulant
medication. J Am Acad Child Adolesc Psychiatry. 1999;38:503.
Stimulant Controversies• Sudden Death
– No evidence of increased risk in healthy children– Do not use in pts with known hx of cardiac
structural/rhythm abnormalities– Guidelines:
• Physical exam• Personal hx of structural heart or rhythm
abnormalities, syncope, dizziness, plapitations, or chest pain
• Family hx of sudden cardiac death <age 30
• Development of tics– Decrease dose– Switch to another stimulant– Adjunct agent to treat tics – Try non-stimulant medication
• Growth suppression– 2 cm in 2 years in MTA study
(20% reduction)– No further reduction if treated 1
additional year– Catch-up or rebound growth may
be possible– Growth Chart with ht/wt q3-4
months if concern

Case Example
• 28 yo male• Past dx of ADHD in 5th
grade—neuropsych testing supported dx (parents refused meds)
• Failed out of college• Struggles to hold down
jobs (3 in last yr)
• 7 Inattentive sxs of ADHD
• Drinks on weekends, sometimes to blackout
• Smokes MJ 5-6 times/week
• Wonders if he should try medicine for ADHD. Thoughts?
Stimulant Controversies: Diversion / Misuse
Stimulants do not alter risk of future substance abuse
– Study design: meta-analysis of 15 studies (N = 2565 patients)
– Findings: Treatment of ADHD with stimulant medication neither protects nor increases the risk of later substance use disorders.

Misuse in college students prescribed stimulants
60-70% used as prescribed36% used too much19% intentionally used with alcohol or drugs8% intranasal use26% diverted medicine to peers
•11% received an ADHD diagnosis including•1 in 5 high school boys•1 in 11 high school girls
•ADHD diagnosis increased by 42% 2003-2011 (5% annual increase)
•7.8% in 2003•11.0% in 2011
•Medication for ADHD increased by 28% 2007-2011 (7% annual increase)

Total Stimulant Prescription Trend
Treatment of ADHD atomoxetine (Strattera)
• Approved in 2002 for ADHD treatment
• Noradranergic re-uptake inhibitor
• > 10 controlled trials demonstrating efficacy
• Long term studies: continued effectiveness
• Once-daily dosing• Benefit in 1-4 weeks• No on/off effect• May help with anxiety• No abuse potential

Treatment of ADHD atomoxetine (Strattera)
• Dosing (4-6+ weeks)– Adult: 40 mg/d x3 days then
80 mg/d (max 100/d)– Kids: 0.5 mg/kg/d x3 days,
then 1.2 mg/kg/d starting dose; 1.4 mg/kg/d max
• Side effects– Abdominal pain– Insomnia– Decreased appetite– Constipation– Fatigue– Dizziness– Sexual side effects– Depression

Treatment of ADHD atomoxetine (Strattera)
– Possible slight increase in suicidal ideation reported in clinical trials
• 0.37% Atomoxetine vs. 0.0% placebo• One suicide attempt/1357 cases; no suicides
– Rare hepatitis reported• One case confirmed/3.4 million exposures• One case suspected/3.4 million exposures
Extended-Release Guanfacine (Intuniv) and Clonidine (Kapvay) for ADHD
• FDA approved for children ages 6-17 to treat ADHD • Dosing / Half-Life:
– Intuniv 1-4 mg qam (18 hours)– Kapvay 0.05 mg to 0.4 mg qd-bid (12-16 hours)
• Pharmacology: – alpha-2a adrenergic agonists
• Efficacy: – improvement in hyperactivity/impulsivity as well as inattention– may be less effective with inattentive-subtype
• Side effects: – somnolence, sedation, abdominal pain, dizziness, hypotension, dry mouth and constipation– use with caution in patients at risk for bradycardia, hypotension, heart block or syncope

Summary: Pharmacotherapy for ADHD
• Stimulants, atomoxetine, extended-release guanfacine, and extended-release clonidine are FDA approved
• Antidepressants (bupropion and TCAs) are second-line agents
• Combined pharmacotherapy for incomplete response:– Stimulant plus atomoxetine, bupropion,
tricyclics, clonidine, or guanfacine
Treating Refractory ADHD
• Evaluate for co-morbidity• Referral for
– Behavioral therapy– Coaching/study skills– Family therapy/parental coaching/play
• Higher doses of medication(s)• Other Medicines not approved by FDA

Treatment of ADHDBehavioral Strategies
• Parent training– Track behavior– Reward system– Catch good behavior– Issuing clear
commands– Establishing house
rules– Time out procedures– Structure time
Connecting Through Play• Tighten the screws with limits
and rules or loosen up with play?
• Children have a need for connectedness, security and attachment
• Play can facilitate these bonds• Connect before you direct or
get angry• "Pretend... that we're really
gonna be late and you're really mad"
Treatment of ADHDBehavioral Strategies
• Teacher/School– Build teacher/student bond– Extra structure, consistency
and organization– Decrease distractions– Extra time for tests– Reminders– Rules / Target behaviors– Effective commands– Rewards/punishments– Tutoring– Daily report card
Power T, Tresco K, Cassano M. School-based interventions for students with ADHD. Current Psychiatry Reports. 2009; 11: 407-14.
Treatment of ADHDExercise
• 20-60 minutes/day of exercise can improve inattention and hyperactivity in ADHD

Stimulant Controversies-CVFDA analysis of amphetamines and methylphenidates from 1992-2005
• 38 cases of sudden death on stimulants (28 in children)
– 12/28 children had structural cardiovascular abnormalities
– 30 million prescriptions 1999-2003 (7 million pts)
• General population (not on stimulants)
– Sudden death rate in children/adolescents: 4-8 per-million per-year
– Rate in pts treated with amphetamines similar to basal rate
– Higher rate of sudden death in athletes– Similar ratio for structural CV
abnormalities with sudden death (about 50% have CV structural abnormality)
• Conclusions:– No evidence of increased risk in
healthy children– Sudden death in kids with structural CV
abnormalities on stimulants equated to strenuous exercise
– Do not use in pts with known hx of cardiac structural/rhythm abnormalities
• Guidelines:– Physical exam– Personal hx of structural heart or
rhythm abnormalities, syncope, dizziness, plapitations, or chest pain
– Family hx of sudden cardiac death <age 30
