ADHD in Children: Objective Present strategies for diagnosis and treatment of disorders commonly comorbid with ADHD in children and adolescents –Disruptive behavior disorders –Anxiety –Depression –Bipolar disorder
Empirically Proven Treatments for ADHD in Children: Psychosocial Interventions Parent education about ADHD 1,2 Parent training in child management 3 –Children (<11 yrs, 65%-75% respond) –Adolescents (25%-30% show reliable change) Family therapy for teens: problem-solving, communication training 4 –30% show change –Best to combine with BMT to reduce dropouts 1.Weiss M.

Empirically Proven Treatments for ADHD in Children: Psychosocial Interventions (cont.) Teacher education about ADHD Teacher training in classroom behavior management Special education services (IDEA, section 504) Regular physical exercise Residential treatment (5%-8%) Parent/family services (25+) Parent/client support groups (CHADD, ADDA, independents) Barkley RA. Attention-Deficit Hyperactivity Disorder: A Handbook for Diagnosis and Treatment. 2nd ed. New York: Guilford Press; 1998.
Major Behavioral Tactics for ADHD Balance the following two strategies: Altering antecedents – getting proactive: –Giving effective instructions –Altering performance settings –Point-of-performance prompts and cues Altering consequences – being reactive: –Positive reinforcement (tokens, rewards, etc.) –Punishment (time outs, grounding, fines, etc.) –Changing schedules (increasing frequency and immediacy of consequences) DuPaul GJ, Stoner G.

ADHD in Childhood: Common Comorbid Diagnoses Approximate Prevalence Rate in Children With ADHD (%) Pliszka SR. J Clin Psychiatry. 1998;59(suppl 7):50-58. Biederman et al. J Am Acad Child Adolesc Psychiatry. 1999;38:966-975. Biederman et al. J Am Acad Child Adolesc Psychiatry. 1996;35:343-351. Spencer et al. Pediatr Clin North Am. 1999;46:915-927. 0102030405060 Male Female Oppositional defiant disorder Conduct disorder Mood disorders Anxiety disorders Learning disorders
Conduct Disorder (CD) A repetitive and persistent pattern of behavior in which the basic rights or well-being of others is disregarded 1 Common symptoms 1 : –Aggression to people or animals –Destruction of property –Deceitfulness or theft –Serious violation of rules CD may be more severe and persistent when comorbid with ADHD 2 1.American Psychiatric Association. DSM-IV; 1994:85-91. 2.Kuhne et al. J Am Acad Child Adolesc Psychiatry. 1997;36:1715-1725.
Oppositional Defiant Disorder (ODD) A negativistic, hostile, and defiant pattern of behavior that varies greatly in severity Common symptoms –Often loses temper –Often actively defies adults –Often deliberately annoys people American Psychiatric Association. DSM-IV; 1994:91-94.
Nature of CD and ODD A descriptive diagnosis; does not imply etiology ODD may be secondary to ADHD CD/ODD may occur even without ADHD CD/ODD are sometimes due to environmental factors (late onset) CD with ADHD may represent a distinct familial subtype and genetic variant of ADHD CD with ADHD is a worse condition than either alone or than their combination would suggest Most likely has multiple causes
ADHD Without and With CD/ODD Without CD/ODD With CD/ODD Prevalence of learning disorder ↑↑↑ Risk for delinquent behavior=↑↑ Risk for substance abuse↑ (adult) ↑↑ (adol & adult) Family history of behavior problems =↑↑ Note: Symbol shows rate relative to controls.
Psychopharmacology of CD/ODD ADHD children with (and without) CD/ODD respond to stimulants 1 Indeed, effect-size changes in ODD symptoms may be as large as those in ADHD symptoms in comorbid cases No evidence that stimulants increase aggression at appropriate doses; evidence shows decreased aggression 2 Relative to placebo, ADHD children on stimulants engage in less antisocial behavior 1.MTA Cooperative Group. Arch Gen Psychiatry. 1999;56:1073-1086. 2.Spencer et al. J Am Acad Child Adolesc Psychiatry. 1996;35:409-432.
ADHD and CD/ODD: Psychopharmacologic Recommendations Divalproex: may be effective for explosive temper and mood lability 1 Risperidone: has reduced disruptive behavior and hyperactivity 2 Atomoxetine: has produced meaningful improvement in ADHD and ODD symptoms 3 1.Donovan et al. Am J Psychiatry. 2000;157:818-820. 2.Aman et al. J Child Adolesc Psychopharmacol. 2004;14:243-254. 3.Newcorn et al. J Am Acad Child Adolesc Psychiatry. 2005;44:240-248.
Psychosocial Treatment of ADHD and CD/ODD in Children When CD/ODD is present, interventions focused on parenting are essential given the recognized contribution of parenting to both disorders Parent training (PT) in behavior management methods has strong empirical support, particularly for addressing the ODD problems in ADHD children PT is most effective (65%-75%) with elementary school- age children but declines markedly by adolescence (30%) Problem-solving communication training combined with behavior management training has the greatest evidence for effectiveness (30%) for those 14 and older –Traditional family therapies are less helpful (10% response rate) Barkley RA. Attention-Deficit Hyperactivity Disorder: A Handbook for Diagnosis and Treatment. 2nd ed. New York: Guilford Press; 1998.
Psychosocial Treatment of ADHD and CD/ODD in Children (cont.) Where CD is present, parental psychological disorders are highly likely and may require additional intervention beyond those for the ADHD child 1 Family relocation to better neighborhoods and schools may also be important and assist with disrupting deviant peer groups, criminogenic neighborhood environments, and ineffective schools 2 Avoid group treatment programs that bring antisocial youth together, as they have been shown to increase antisocial behavior outside the group (deviancy training) 2 Multisystemic therapy that involves therapists in the home setting daily is an empirically supported alternative to traditional clinic-based therapies or incarceration for juveniles 3 1.Biederman et al. J Am Acad Child Adolesc Psychiatry. 1996;35:343-351. 2.Dishion et al. Am Psychol. 1999;54(9):755-764. 3.Henggelar et al. J Am Acad Child Adolesc Psychiatry. 2003;42:543-551.
ADHD and Anxiety Disorders Children with ADHD and comorbid anxiety disorders tend to display: – High levels of arousal – Fearfulness, separation anxiety – Phobias, fear of sleeping alone – Fear of social situations – Anxiety beyond that associated with consequences of misbehavior Anxiety symptoms must be overt; should not be assumed to be present based on ADHD symptoms alone ONLY SIGNIFICANT, IMPAIRING ANXIETY SHOULD BE A FOCUS OF PHARMACOLOGIC TREATMENT Spencer et al. Pediatr Clin North Am. 1999;46:915-927.
ADHD and Comorbid Depression Major depressive disorder –Pervasive sadness or irritability nearly every day –Loss of energy –Guilt –Serious suicidal ideation –Suicidal gestures –Cannot be reassured –Chronic low self-esteem Dysphoria or “demoralization” –Brief periods of sadness when frustrated –Energy normal –Lack of guilt except when in trouble –Brief threats of self-harm when frustrated –Responds to redirection –Positive attitude about good areas of function ONLY MAJOR DEPRESSIVE DISORDER SHOULD BE A FOCUS OF ANTIDEPRESSANT TREATMENT American Psychiatric Association. DSM-IV; 1994:317-327, 339-350.
Pharmacologic Treatment of Depression in Children Pooled all studies, published and unpublished Blinded reviewers at Columbia assessed each adverse event as to its self-harm potential N >4,000 No completed suicides 4% suicidal ideation on drug vs 2% on placebo, statistically significant difference FDA Meta-analysis FDA Public Health Advisory.

Treatment for Adolescents With Depression Study (TADS) Response rates –Fluoxetine + CBT: 71% –Fluoxetine alone: 61% –CBT alone: 43% –Placebo: 35% Presence of SI –29% at baseline –All 4 groups improved significantly, but SI still higher in SSRI group CBT = cognitive-behavioral therapy; SI = suicidal ideation; SSRI = selective serotonin reuptake inhibitor. March et al. JAMA. 2004;292:807-820.
Treatment of ADHD With MDD: Stimulant First vs Antidepressant First Stimulant first 1,2 –ADHD chief complaint –ADHD symptoms more disabling –MDD found on interview, no current functional impairment from depression –Mild neurovegetative signs –ADHD symptoms clearly preceded MDD symptoms 1.Pliszka et al. ADHD with Comorbid Disorders: Clinical Assessment and Management. New York: Guilford Press; 1999. 2.Pliszka et al. J Am Acad Child Adolesc Psychiatry. 2000;39:908-919.
Treatment of ADHD With MDD: Stimulant First vs Antidepressant First (cont.) Antidepressant first 1,2 –Clear history of stimulant nonresponse –Prominent neurovegetative signs/ health compromised –MDD present complaint –ADHD symptoms late onset or coincident with MDD symptoms –Suicidal/psychotic 1.Pliszka et al. ADHD with Comorbid Disorders: Clinical Assessment and Management. New York: Guilford Press; 1999. 2.Pliszka et al. J Am Acad Child Adolesc Psychiatry. 2000;39:908-919.
Treatment of ADHD With Anxiety Start with stimulant first unless 1,2 : –Full-blown panic symptoms –Full-blown separation anxiety with complete refusal to separate, but: Studies conflict on whether children with anxiety have poorer response to stimulants –Consider using atomoxetine for both ADHD and anxiety or as a supplement to stimulant treatment –May add SSRI to stimulant to treat anxiety 1,2 1.Pliszka et al. ADHD with Comorbid Disorders: Clinical Assessment and Management. New York: Guilford Press; 1999. 2.Pliszka et al. J Am Acad Child Adolesc Psychiatry. 2000;39:908-919.
Psychosocial Treatment of ADHD With Anxiety/Depression Comorbid ADHD/anxiety shows best response to behavioral and social skills intervention 1 Cognitive therapy relative to ADHD alone or with other disruptive disorders may be helpful 2 –In behavioral token systems, keep thresholds for success low initially; high likelihood of success eliminates worry about earning quotas for privileges Low self-esteem is specifically associated with comorbid depression, not due to ADHD Use “go slow” approach to punishment contingencies (eg, time outs) in comorbid ADHD/depression so as not to contribute to depressive cognitive schemas –Start with all-reward programs until depression symptoms lift, then introduce selective mild punishments 1.MTA Cooperative Group. Arch Gen Psychiatry. 1999;56:1088-1096. 2.Brent et al. Arch Gen Psychiatry. 1997;54:877-885.

ADHD and Mania: Treatment If floridly manic, stabilize mood before treating ADHD (or discontinue ADHD treatment until mood stabilized) –Stimulant may be added to mood stabilizer or atypical antipsychotic later If mania/BP diagnosis is equivocal, treat ADHD first –If all symptoms resolve, mania unlikely If stimulant or ADHD medication induces partial remission of ADHD and manic symptoms without worsening of manic symptoms, may add atypical antipsychotic or classic mood stabilizer (lithium or valproate) Spencer et al. Attention-deficit/hyperactivity disorder with mood disorders. In: Brown TE, ed. Attention-Deficit Disorders and Comorbidities in Children, Adolescents, and Adults. Washington, DC: American Psychiatric Press; 2000:79-124.
ADHD and Mania: Treatment (cont.) Use diagnosis of intermittent explosive disorder for children with severe aggression but no other symptoms of mania –Atypical antipsychotic, lithium, or valproate may be added to stimulant for treatment of aggression Do not use atypical antipsychotic for ODD symptoms alone Spencer et al. Attention-deficit/hyperactivity disorder with mood disorders. In: Brown TE, ed. Attention-Deficit Disorders and Comorbidities in Children, Adolescents, and Adults. Washington, DC: American Psychiatric Press; 2000:79-124.
Psychosocial Treatment of ADHD and Bipolar Disorder Limit behavioral contingencies to all positive approaches to reduce explosive outbursts in response to parental limit-setting Consider Ross Greene’s program for the explosive child Interventions are more likely to be focused on parental coping with explosive episodes rather than remediation of disruptive behavior Counsel parents on stress management –ADHD/BPD cases have the highest rates of physical abuse and PTSD of all ADHD cases Special educational services in BPD/ED classes under IDEA are likely given severely disruptive behavior
ADHD in Children: Summary Strategies for managing ADHD in children comprise a combination of pharmacologic and psychosocial interventions, including parent training in behavior management These strategies can also be effective in managing disorders commonly comorbid with ADHD –Disruptive behavior disorders –Depression and anxiety disorders –Bipolar disorder Developing a treatment plan for children with ADHD and comorbid disorders requires careful evaluation of the symptoms and severity of each disorder Guidelines for effective management of pediatric ADHD and associated comorbidities are evolving, based on research findings and clinical experience
