ADHD DSM-IV-TR Criteria
Adapted from Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. Washington, DC,
American Psychiatric Association, 2000.
A
Either 1 or 2:
1. Six or more of a list of nine symptoms of inattention have been present for
at least 6 months, to a degree that is maladaptive
2. Six or more of a list of nine symptoms of hyperactivity-impulsivity have
been present for at least 6 months, to a degree that is maladaptive
B
Some symptoms that cause impairment were present before age 7 years.
C
Some impairment from the symptoms is present in two or more settings (e.g. at
school/work and at home).
D
There must be clear evidence of significant impairment in social, school, or work
functioning.
E
The symptoms are not better accounted for by another mental disorder
ADHD DSM-IV-TR Criteria
Inattention
(a) often fails to give close attention to details or makes careless mistakes in schoolwork, work, or other activities
(b) often has difficulty sustaining attention in tasks or play activities
(c) often does not seem to listen when spoken to directly
(d) often does not follow through on instructions and fails to finish school work, chores, or duties in the workplace
(not due to oppositional behavior or failure to understand instructions)
(e) often has difficulty organizing tasks and activities
(f) often avoids, dislikes, or is reluctant to engage in tasks that require sustained mental effort (such as schoolwork
or homework)
(g) often loses things necessary for tasks or activities (e.g., toys, school assignments, pencils, books, or tools)
(h) is often easily distracted by extraneous stimuli
(i) is often forgetful in daily activities
Hyperactivity -Impulsivity
(a) often fidgets with hands or feet or squirms in seat
(b) often leaves seat in classroom or in other situations in which remaining seated is expected
(c) often runs about or climbs excessively in situations in which it is inappropriate (in adolescents or adults, may
be limited to subjective feelings of restlessness)
(d) often has difficulty playing or engaging in leisure activities quietly
(e) is often "on the go" or often acts as if "driven by a motor"
(f) often talks excessively
(g) often blurts out answers before questions have been completed
(h) often has difficulty awaiting turn
(i) often interrupts or intrudes on others (e.g., butts into conversations or games)
Is ADHD Real?
• One of the most studied disorders of childhood with
several thousand publications in peer refereed journals
• Affects 5% to 8% of US children
• Statistics replicated throughout the world
• However, there is a small but vocal segment that insists
ADHD was invented by pharmaceutical companies to
sell drugs
Jan Steen - The Village School- 1665
Kast & Altschuler; The earliest example of the hyperactivity; 2008 South African medical journal
Jan Steen - The Village School - 1670
Sir Alexander Crichton (Scottish MD)
• In 1798 in the chapter of Attention in his book: An
inquiry into the nature and origin of mental
derangement
• Described a mental state with al the essential features of
the inattentive subtype of ADHD, the restlessness,
problems with attention, the early onset and how it can
affect the ability to perform in school.
ADHD is highly heritable
According to a metastudy by Faraone et al
in Biol Psych 2005;57:1313-1323, ADHD
mean heritability is 0.75 reaching almost
the heritability of height.
According to Shaw, Arch Gen
Psychiatry. 2006;63:540-549, cortical thickness in
ADHD compared with controls is significantly
thinner regions in the ADHD group.
Academic Impairment
• Very well documented
▫ Failure to perform academically is the single most common
source of referral for children and adolescents
• Children with ADHD
▫ Perform poorly on achievement tests and fail grades /
courses significantly more often than children without
ADHD
▫ Complete 3 fewer years of education than matched controls
▫ More likely not to graduate from high school (35%)
• Academic impairment more profound when learning
disabilities are present
Weiss & Hechtman Hyperactive Children Grown Up 1993
Manuzza & Klein The Economics of Neuroscience, 2001:47-53
Social Impairment
• Social problems begin in childhood, persist into
adolescence
▫
▫
▫
▫
▫
▫
Fewer friends, more limited social skills
Lower self esteem on assessment scores
3X’s as likely to have trouble getting along with peers
½ as likely to have good friends
2Xs as likely to get picked on by peers
3Xs as likely to have problems that limit after school
activities

Diagnostic Approach
• Despite significant advances in
anatomical/genetic research, there is NO current
validated biological marker
• Psychiatric interview and history remain the best
diagnostic tools
▫ Rule in (ADHD)
▫ Rule out (Mimics)
Rule in Approach
• Psychiatric Interview
▫ Family (family hx of ADHD)
▫ Child (school/social performance)
▫ Parents (marital/parental function)
• Collateral Information
▫ Rating Scales from Teacher (most reliable guide of
treatment progress)
▫ Discussion with teacher if available
▫ Discussion with grandparents if involved

Trends in Prevalence of Stimulant Use
1987–2008
Zuvekas Am J Psychiatry. 2012;169(2):160-166
Since 1987, there has been a signficant
increase overall for ages 0-17. However, the
largest increase has been for ages 12-17 while
there was a decrease for ages 0-5.
Stimulant Treatment
Bennett Silver, MD
Societal and Workplace Impact of ADHD
• ADHD cost the U.S. economy between 143 billion and
266 billion in 2010
• That is roughly $2,000 per household
• Although commonly thought of as a childhood disorder,
adults with ADHD accounted for 73% of those estimated
costs
• The majority of these costs were the result of lost
productivity (62%), healthcare (26%), education (10%),
and the criminal justice system (2%)
• Effective treatment plans can improve the outcome of
ADHD and reduce these costs to society
*Congressional briefing on societal and workplace impact of untreated ADHD, November 30,2011
Stimulants
• Gold standard, first line treatment
• There are two chemical families with almost identical
therapeutic properties
▫ Amphetamines (AMPH)
▫ Methylphenidates (MPH)
• Amphetamines first used in 1937
• Stimulants are very effective (80%) and very safe.
• Only difference amongst multiple preparations is
duration of action
Short Acting Stimulants (up to 4hrs)
• MPH products
▫ Ritalin
▫ Methylin
▫ Focalin
• AMPH products
▫ Dexedrine
▫ Dextrostat
▫ Adderall
Long Acting Stimulants (More recently
approved)
• MPH products
▫ Oral (6-10 hrs)






Methylphenidate-SR
Ritalin (SR or LA)
Methylin-ER
Metadate (CD or ER)
Concerta (8-10 hours)
Focalin XR (8-10 hours)
▫ Patch (duration depends on length of time patch on)
 Daytrana
• AMPH products
 Adderall XR (8-10 hours)
 Vyvanse (at least 13 hours in children)
Choice of Stimulant
• It does not matter which MPH or AMPH starts first
• Most children will respond to one or the other
• If one is not effective or induces side effects, the child is
switched to the other one
▫ This strategy improves over 80% of patients
• Over 70% of psychiatrists prefer long acting
formulations
▫ Avoids having to see the nurse at noon
▫ Longer duration helps with homework
▫ Avoids rebound emotional lability as dose wears off
Stimulant Side Effects
• FREQUENT
▫ Decrease appetite
▫ Difficulty falling asleep
▫ Mood lability
▫ Stomach upset
▫ Dry Mouth
▫ Irritability
• INFREQUENT
▫ Clinically significant increased pulse or blood pressure
▫ Motor tics, Tourette’s
▫ Weight loss, slowed growth
▫ Psychosis
• Do not use in those with arrhythmias or other heart abnormalities
• Can be used as substance of abuse, to be avoided in active SA
Incomplete Diagnosis Can Lead to
Inadequate Treatment
• Sometimes ADHD is correctly diagnosed, appropriate
treatment and proper medication are initiated, but the
student only partially responds
• When this occurs it is necessary to look for co-existing
psychiatric disorders that may also require treatment
• As many as two thirds of children and adolescents with
ADHD have at least one other co-existing condition

Substance Abuse (30%-35%)
Sleep Disorders (30%-75%)
Is Substance Abuse More Common in Teenagers
Who Are or Were Treated with Stimulants?
• Youths with ADHD are at increased risk for substance
abuse; about one-and-a-half times greater risk than nonADHD youths*
• Current research documents that those adolescents with
ADHD prescribed stimulant medication are less likely to
subsequently use illegal drugs than are those not
prescribed medication **

Non-Stimulants and New
Approaches
Gabriel Kaplan, MD
Stimulants vs. Non-Stimulants
• Stimulants strengths
▫
▫
▫
▫
▫
Act right away
Very effective
Gold standard
Many preparations, multiple dosage strengths
Well tolerated
• Stimulants weaknesses
▫ Controlled substances
▫ 20% non response
▫ Some patients do not tolerate AEs
When to use a Non Stimulant
• A Stimulant trial has failed
▫ Non effective or intolerable side effects
• Parents do not want to use a controlled
substance
• There is active drug abuse in the patient or
family
• There is a contraindication
▫ Sensitivity, heart problems
▫ Presence of Co-morbidities: ODD, Anxiety
Strattera
• Takes 3-4 weeks to work
• Selective Norepinephrine Reuptake Inhibitor SNRI (it
makes more NE available)
• Once per day dosage
• Although studies proved efficacy, in clinical practice,
physicians have been disappointed and is used less and
less often
Strattera Side Effects
• FREQUENT
▫
▫

▫
Liver failure
Suicidal thoughts
Urine retention
Cardiac complications
Psychosis
Intuniv
• Guanfacine Extended Release
• Approved 9/2009
• Acts on the same receptor as Norepinephrine (Selective
Alpha 2A)
• Its action, thus, mimics increased NE
• Taken once per day
• Takes a minimum of 2 weeks but most likely up to 4
weeks to work
Intuniv Side Effects
• FREQUENT
▫ Sedation
▫ Somnolence
▫ Fatigue
▫ Headache
▫ Increased appetite
• INFREQUENT
▫ Clinically significant low BP or heart rate
▫ Syncope
▫ Dizziness
Kapvay
• Clonidine Extended Release
• Approved 10/2010
• Acts on the same receptor as Norepinephrine (Alpha 2
non selective)
• Its action, thus, mimics increased NE
• Taken twice per day
• Takes a minimum of 2 weeks but most likely up to 4
weeks to work
Kapvay Side Effects
• FREQUENT
▫ Sedation
▫ Somnolence
▫ Fatigue
▫ Headache
▫ Increased appetite
• INFREQUENT
▫ Clinically significant low BP or heart rate
▫ Syncope
▫ Dizziness
How do you know the medication works
1. Executive Functions have improved
 Decreased impulsivity and motor behavior
 Increased attention
2. As shown by teacher reports (the most reliable
outcome measure)
 Via Rating scales: Conner's, etc or phone contact
with the provider directly or via parents
3. And there are no significant side effects
Newly Approved Combination Therapy
• Use a stimulant and a non stimulant at the same time
• Approved recently for Kapvay (2010) and Intuniv (2011)
but in use for decades with IR preparations
• For stimulant partial responders
Newly Approved Combination Therapy
• Stimulant Side Effects
▫ Anorexia
▫ Insomnia
▫ Hypertensive
• Non Stimulant Kapvay/Intuniv Side Effects
▫ Increased appetite
▫ Sedation
▫ Hypotension

Non- Medication Approaches
Bennett Silver, MD
Despite the Well Documented Benefits of
Medication for ADHD
• As many as 20% of children with ADHD derive
inadequate benefit from medication
• Side effects prevent some from receiving medication on
an extended basis
• Even those who benefit from medication may still have
difficulties with primary ADHD symptoms or associated
problems which must be targeted via other means
• Mild ADHD may be managed without medication
• Some parents and teens will refuse medication

Behavior Therapy Based on Principles About
What Leads Children to Behave Appropriately
• Children want to please their parents and feel good
about themselves when their parent is proud of them
• Children behave appropriately to obtain positive
consequences (privileges/rewards)
• Children want to avoid negative consequences that
follow inappropriate behavior
Behavior Therapy Core Concept
• Increase the frequency of desirable behavior with
positive consequences for good behavior
• Reduce inappropriate behavior with negative
consequences for bad behavior
Positive Reinforcement Basic Principles
1
• Be very clear about what behavior is expected of the
student in order to earn a reward
• “Listen to what I say” is too vague
• “Take your seat without talking the first time I ask you
to do so” is more specific
Positive Reinforcement Basic Principles
2
• Make sure that the expectations you have for a student
are reasonable – do not set the student up for failure
with expectations that are not appropriate for his/her
abilities
• This includes in class activities as well as homework
assignments
Positive Reinforcement Basic Principles
3
• Don’t try to work on too many different things at one
time
• It is better to concentrate on a few things that are very
important rather than taking on too much at once –
choose your battles carefully!
Positive Reinforcement Basic Principles
4
• Let the student participate in the type of rewards he or
she can earn – they will be more invested in a program
when they have input into its design. Let it be something
you are doing with them rather than to them
• Design the program so that there is a good chance to
experience initial success – this will enhance motivation
and you can gradually raise the bar
Positive Reinforcement Basic Principles
5
• Provide many social rewards (praise) in addition to
tangible rewards that can be earned – this will increase
the student’s desire to please you and generate positive
feelings between you
• Be consistent – apply the program daily and always
provide rewards when they are earned
Negative Reinforcement Basic Principles
• When a negative behavior is consistently followed by
negative consequences that behavior should diminish in
frequency and intensity
• The punishment for specified bad behaviors is clear –
e.g., time-out, loss of privilege, loss of points or tokens
• The student will understand that there is simply no payoff for bad behavior
Negative Reinforcement Basic Principles
(Cont.)
• Try not to overdo the negative consequences
• Students get discouraged and lose interest in the
program if they are used too frequently
• Resorting to negative consequences too often means you
should re-evaluate your program and possibly redesign it
• Utilize a pre-planned graded series of punishments for
persistent misbehavior
Modifications to a Behavioral Program
Specific to an ADHD Student
• Give more frequent feedback to the student about how
they are meeting teacher expectations – e.g., hourly
instead of daily
• Utilize short term goals, with shorter intervals between
the opportunity to earn rewards – points or tokens are
especially helpful
• More frequent reminders about expectations and what
can be earned by good behavior
• Frequent changes in the program to sustain interest in it
