The Case: The scatter-brained mother whose daughter has ADHD, like mother, like daughter

The Question: How often does ADHD run in families?

The Dilemma: When you see a child with ADHD should you also evaluate the parents and siblings?

Pretest Self Assessment Question (answer at the end of the case)

Patients with comorbid ADHD and anxiety should in general not be prescribed stimulants

A. True B. False

Patient Intake • 26-year-old woman • Has a daughter with ADHD • Psychiatrist noted symptoms in the mother and suggested she come

in for her own evaluation • See the previous Case 13, p 133 for presentation of the daughter’s

case

Psychiatric History • During interviews with the patient’s daughter (also attended by the

patient) over the past several months, it was not only noted that the daughter has ADHD with comorbid ODD, but that the mother also exhibited multiple symptoms consistent with lifelong and undiagnosed ADHD including

– Mother misses appointments or is late for appointments – Often appears disorganized – Did not fi ll out her child’s forms on time – Did not deliver forms to her child’s teacher, forgot, lost them – Admits being very disorganized since her second child started

school – Feels overwhelmed by two children and her life circumstances – Could also have some signs of depression – Can’t get organized to take her child to CBT – Has a hard time keeping a regular schedule and also keeping her

daughter on a regular schedule of going to bed and waking up – Was unable to remember to remove the daughter’s skin patch

unless she set a cell phone alarm – All these suggest further evaluation of the mother is indicated

since ADHD commonly runs in families and has a very high genetic contribution

• Has always done poorly academically • Has always felt intimidated by any type of testing • In addition, reports that she has always been worried about the future

and fi nancial stability of her family • Says she sometimes mentally “freezes when it gets to be too much” • When her eight year old daughter was diagnosed with ADHD, she

suddenly realized that she had similar problems as a child • The psychiatrist explained to her that ADHD was highly heritable and

that there was a 75% chance of having a child with ADHD if both parents have ADHD and thus was asked to fi ll out an Adult ADHD screening form

Social and Personal History • High school drop out, age 17 after getting pregnant • Married age 17, divorced 2 years later • Two children, ages 8 and 6 • Smoker • No drug or alcohol abuse • Single mother works full time in retail • Father not much involved with his children

Medical History • None notable • BP normal • BMI normal • Normal lab tests

Family History • 8-year-old daughter: recently diagnosed with ADHD • Other family history unknown as the patient was adopted • See the previous Case 13, p 133 for presentation of the daughter’s

case

Patient Intake • The last time the patient brought her child to see the psychiatrist, the

mother was asked to fi ll out her own checklist, the Adult ADHD Self Report Scale Symptom Checklist

– She endorsed many items, mostly inattentive but not really hyperactive or impulsive such as:

– Having trouble wrapping up the fi nal details of a project once the challenging parts have been done

– Diffi culty getting things in order – Diffi culty remembering appointments or obligations

153

– Making careless mistakes on diffi cult projects – Diffi culty keeping attention on repetitive work – Misplacing things at home and work – Distracted by activity around her – Diffi culty unwinding and relaxing when having time to herself – Diffi culty focusing/listening during conversations

• Earlier, the mother was also requested to obtain copies of her report cards from fi rst and second grade

– Her own mother had kept these in storage – Showed grades that were quite low – Her teachers had commented on some of the problems endorsed

in the adult ADHD checklist that she continues to experience as an adult

• Asked how these problems affect her life, she states that: – They cause great diffi culty managing family matters – She used to be unable to stay focused in conversations with her

ex-husband, which made him feel she did not care about him • Additional complaints include:

– Constantly feeling overwhelmed with taking care of the two children while working fulltime

– Blaming herself for her daughter’s academic diffi culties – Feeling very emotional and overwhelmed

– “I’m sorry, doctor, but two kids are just too much for this single mom”

• Having diffi culty sleeping and being irritable with the children at night, which she regrets later on

• Has many worries, about fi nances, about the future, about her children’s futures, about getting a better job, about getting her own education, about fi nding a new partner

Based on just what you have been told so far about this patient’s history and symptoms, what do you think is her diagnosis?

• Appropriate response to her circumstances with her severe psychosocial stressors

• Mostly just stress and anxiety • ADHD • ADHD and stress • Generalized anxiety disorder (GAD) • Major depressive episode • ADHD and GAD • Other

Attending Physician’s Mental Notes: Initial Psychiatric Evaluation • Here is a case that indeed is ADHD, but her symptoms also suggest

that she suffers from GAD – Constant worry – Feeling on edge – Fatigue – Diffi culty concentrating and her mind going blank – Irritability – Trouble sleeping

• Most adults with ADHD are comorbid for a second psychiatric disorder, and the most common is GAD

• Also, this patient is a smoker which may be related to her ADHD since a disproportionate number of ADHD patients smoke, perhaps because of the therapeutic effects of nicotine on ADHD symptoms

How would you treat her?

• Stimulant for her ADHD • SSRI/SNRI for her GAD • Benzodiazepine as need for GAD and insomnia • Stimulant plus an SSRI/SNRI or benzo for both ADHD and GAD • CBT for both ADHD and GAD • Other

Attending Physician’s Mental Notes, Initial Psychiatric Evaluation, Continued • It seems as though the primary disorder is ADHD and it will be

simplest if this is treated fi rst, with a single drug, probably a stimulant • An SSRI/SNRI and/or benzodiazepine can be added at a later time

once the actions of the stimulant are evident • Even though patients with GAD alone or even normal controls may be

“over stimulated” by a stimulant, in many cases of ADHD comorbid with GAD, the stimulant is paradoxically calming and well tolerated and even works for GAD symptoms as well as ADHD symptoms without having to prescribe a second medication for the GAD

• Any stimulant could be chosen but not all are explicitly approved for treatment of ADHD in adults

• She was started on mixed salts d,l amphetamine XR (Adderall XR) • She was referred to a local mental health training program where she

could possibly get CBT for free or for a reduced rate from a trainee receiving supervision

Case Outcome: First, Second, and Third Interim Followup Visits, Weeks 4, 8 and 12 • Due to scheduling issues, by the time the patient had her fi rst CBT

session, she had already been titrated to 20 mg of mixed salts of d,l – amphetamine XR

• She thought that the medication had already started to help her and in fact that she would not have been able to cooperate with the CBT assignments had she not been on the medication

• Because of lack of side effects but continuing ADHD and GAD symptoms, the dose of d,l-amphetamine XR increased to 30 mg (off label since the maximum approved dosage for adults is 20 mg)

• Her BP and pulse were stable on the 30 mg dose but she felt jittery particularly in the morning and around noon; she also felt very anxious about her job situation and being able to provide for her family

• Dose lowered to 25 mg, but the jitteriness persisted so the dosage was further lowerd to 20 mg

• The jitteriness abated but her ADHD symptoms were not well controlled on the 20 mg dose anymore

• Instructed to stay on 20 mg for two more weeks as she is going on vacation and not to change the dose until after her vacation and then retry the 25 mg dose again

• Complained of feeling overwhelmed and irritable • For most patients, a week between dosing adjustments for a stimulant

being used to treat ADHD is quite adequate • Weekly intervals give patients and clinicians a chance to see the way

that the dosage is working though the spectrum of challenges that occur in a typical week

• As vacations do not represent typical activities for a week, special consideration must be given to the effectiveness of medication changes that are done while a patient is on vacation

– Many adults with ADHD may relax on vacation and not challenge themselves with cognitive loads and multitasking so may appear to be better even without a medication change

– Other adults with ADHD, especially women with young children, may actually fi nd vacation more challenging

– For example, a parent with ADHD taking a family vacation with several children in tow may fi nd the planning and organization for the trip more taxing than anything encountered at work or during the normal routine at home

– It can also be diffi cult to manage timing the medication appropriately when traveling to different time zones

Case Outcome: Fourth Interim Followup, Week 16 • “Glad to be back from vacation” • “I don’t think I could have even got through our vacation without my

medication, but I still have a hard time holding things together” • On at least 20 mg/day dosage of d,l-amphetamine XR combined with

CBT for 12 weeks, including a couple of weeks back from vacation, the patient still has problems with

– Organizing her day – Procrastinating – Following instructions – Losing items such as her keys which make her late for

appointments/activities • On the few days that the patient missed, and thus skipped, her

medication inadvertently she realized that the medication was really helping her concentrate and get through the day even though she remains symptomatic

• Knowing that she could achieve better functioning on medication she asked if other medications might accomplish this without the jittery and anxious feelings

• While other medication options were discussed, the CBT was continued which was slightly less helpful

How would you treat her now?

• Start lisdexamfetamine 30 mg once in the morning and titrate the dosage by 20 mg each week until an optimal dosage is achieved

• Start d-methylphenidate XR 10 mg once in the morning and titrate the dosage by 10 mg each week until an optimal dosage is achieved

• Start OROS methylphenidate 18 mg once in the morning and titrate the dosage by 18 mg each week until an optimal dose is achieved

• Start atomoxetine 40 mg a day and increase to 80 mg after one week

Attending Physician’s Mental Notes: Fourth Interim Followup, Week 16 • Lisdexamfetamine, d-methylphenidate XR, OROS methylphenidate,

and atomoxetine are all FDA-approved for the treatment of adults with ADHD

• On the one hand, the patient found her amphetamine-based stimulant to be very effective, and thus another long-acting stimulant would be reasonable

• On the other hand, she had jitteriness with the stimulant, and thus a non-stimulant would be equally reasonable

• After explaining the options, the patient elected to try another long- acting stimulant

The Scatter-brained Mother whose Daughter has ADHD Case Study

PATIENT FILE

157

• d-methylphenidate uses a bead-based technology similar to the mixed salts amphetamine XR in that 50 percent of the beads are immediate- release and 50 percent delayed-released

• Methylphenidate LA and d-methylphenidate XR employ the same patented SODAS technology in their delivery systems, but other long- acting forms of stimulants with beaded delivery systems vary due to proprietary differences in their manufacturing processes

• For instance, one formulation of methylphenidate utilizes a capsule that contains a ratio of 30 percent immediate-release beads and 70 percent delayed-released beads

• Although the different technologies used in beaded forms of stimulants can have clinical implications in individual cases, they all follow a similar design scheme:

– A bolus of stimulant medication becomes bioavailable rather quickly as the immediate-release beads dissolve

– Over time, the coating on the delayed-release beads deteriorates, allowing the stimulant contained within the bead to be released

– The medication within the delayed-release bead becomes bioavailable about four hours after the patient swallows the capsule

• Lisdexamfetamine is the only stimulant preparation that is a prodrug: – In its prodrug form, a lysine molecule is attached to

dextroamphetamine – Dextroamphetamine will not be active until the lysine is cleaved

from it – Cleaved lysine is an amino acid that does not contribute to the

clinical effi cacy of this medication • Lisdexamfetamine could be a good choice for multiple reasons:

– It uses a different delivery system that appears to have a more consistent interval to maximum concentration (Cmax)

• It is conceivable that the jitteriness this patient was experiencing was related more to the l-isomer than to the d-isomer

• A nonstimulant such as atomoxetine may be particularly useful in a patient who has stimulant related side effects, because atomoxetine does not cause these side effects

• Also, atomoxetine may be particularly useful in patients with comorbid anxiety

Case Outcome: Fourth Interim Followup, Week 16, Continued • In the end, the patient and the attending physician agreed upon a trial

of OROS methylphenidate (Concerta) • Main reasons for this choice:

– To be able to compare the benefi ts the patient experienced on an amphetamine preparation with those of a methylphenidate

The Scatter-brained Mother whose Daughter has ADHD Case Study

PATIENT FILE

158

preparation since patients may experience differing tolerabilities as well as effi cacies on methylphenidate versus amphetamine

– To be able to test the uniqueness of the OROS delivery system in terms of attained effi cacy with better tolerability

• OROS methylphenidate uses a delivery system that is quite different from beaded delivery systems:

– Coating of OROS methylphenidate contains 32 percent of the medication

– Remainder of medication is contained within a permeable membrane that allows water from the gut to enter once the coating of methylphenidate dissolves away

– Different concentrations of methylphenidate in gel form are contained in two compartments

– A push compartment absorbs water and expands like a sponge does, pushing the methylphenidate gel out of the hole at the opposite end

Case Outcome: Fifth Interim Followup, Week 20 • The patient’s dose was titrated from 18 mg to 72 mg over the course

of four weeks • Although she did not feel jittery, OROS methylphenidate 72 mg once a

day did not seem to work as well as the mixed salts amphetamine at 30 mg a day

• She voiced concerns that the dosage was more than double that of the mixed salts amphetamine dosage that was tried

• The psychiatrist explained that methylphenidate compounds are half as potent as amphetamine ones, and that 72 mg/day is an approved dose in adults

• She was reminded that her blood pressure and pulse had remained in the normal range throughout the titration, and she was told that some of the methylphenidate gel may remain inside the delivery system and not be bioavailable (inherent properties of OROS technology)

• After documenting that information about off-label use was given to the patient, the psychiatrist recommended to further increase the dose of OROS methylphenidate to 90 mg

Case Outcome: Sixth Interim Followup, Week 24 • The patient felt that 90 mg of OROS methylphenidate worked at least as

well as 30 mg of the mixed salts of d,l amphetamine XR • Her blood pressure and pulse increased a bit from baseline, but they

were still in the middle of the normal range

• She still has some problems with organization and losing items, but she indicates she would continue CBT to address these

• Similar to when she was on the amphetamine compound, once her ADHD symptoms abated, her anxious feelings became more prominent

– “It’s like now that I can concentrate on my daily tasks, I also feel much more anxious about the fi nancial security of my children, and I often feel my throat tighten when I think about the fi nancial impact of the girls going to college”

– “The thought of losing my job or getting sick frightens me . . . what would happen to the girls?”

– She has trouble falling asleep at night, as her mind does not shut off

ADHD is often comorbid with other psychiatric disorders and one disorder can mask the symptoms of another. In the present case, this patient exhibits symptoms of anxiety, probably generalized anxiety disorder, especially more prominent every time her ADHD symptoms abate. How would you address the patient’s anxiety at this point?

• Augment with a benzodiazepine • Augment with buspirone • Augment with a selective serotonin reuptake inhibitor (SSRI) or SNRI • Incorporate techniques to resolve anxiety into ongoing CBT

Case Outcome: Seventh and Eighth Interim Followup, Weeks 24 and 36 • Incorporating techniques to resolve anxiety into the patient’s ongoing

CBT would likely be most appropriate, prior to attempting to add a medication

• A letter was sent suggesting this to the CBT therapist, but after 12 weeks, this led to limited benefi t, and thus medication augmentation was considered

• Benzodiazepines, buspirone, and SSRIs/SNRIs can all be used to treat generalized anxiety disorder and are not contraindicated with stimulants

• After discussion of the options, paroxetine was prescribed to augment her stimulant and her CTB

Case Outcome: Ninth Interim Followup, Week 48 • After three months on OROS methylphenidate and paroxetine, while

continuing her CBT, at fi rst the patient stated that she “had her life back” • Then, after thinking back over the past year of treatment, and to how

she had been since childhood she stated, “No, I don’t have my life back – I fi nally have a life!”

Case Debrief • It took a long time to get both the ADHD and GAD recognized • It took over a year of trial and error and combination treatment to

attain a remission of symptoms • Real remission will come when sustained improvement of symptoms

leads to better functional outcomes, not only less subjective distress, but now perhaps the chance for an education, a better job, and having enough emotional reserve to develop another relationship

• Stopping smoking might be a goal to tackle in the next year as well

Take-Home Points • ADHD is highly heritable • It is not uncommon for adults with previously undiagnosed ADHD to

recognize their own symptoms once their child is diagnosed • A multigenerational approach should be considered for parents who

have ADHD and who care for children with ADHD • In the patient’s case, by addressing her own ADHD issues, she also

felt she could be a better parent to her daughter with ADHD

Performance in Practice: Confessions of a Psychopharmacologist • What could have been done better here?

– Perhaps ADHD could have been recognized earlier – Perhaps CBT could have been implemented earlier – Perhaps she should have been more actively engaged or have had

more serious discussions about smoking cessation already • Possible action item for improvement in practice

– Make a concerted effort to keep contact with low cost CBT resources in the community

– Make a more concerted effort to encourage smoking cessation

Tips and Pearls • Prescribing stimulants to an ADHD patient is very much like tailoring a

“bespoke” treatment, one case at a time • That is, some patients respond very differently to amphetamine than

they do to methylphenidate • Many patients respond very differently to one controlled dosage

pattern versus another • Look for comorbidities in adult ADHD, including both anxiety

disorders and substance dependence/abuse (especially smoking) • True remission means reduction not just in symptoms of ADHD, but

in the comorbid conditions as well

able B. KQ2: Long-term (>1 year) effectiveness of interventions for ADHD in people 6 years and

older Conclusion

Medication Treatment

Level of EvidenceIntervention SOE: Low Very few studies include untreated controls.

Studies were largely funded by industry. SMD: -0.54 (95% Cl, -0.79 to -0.29)

MPH:

Psychostimulants continue to provide control of ADHD symptoms and are generally well tolerated for months to years

ATX: at a time. The evidence for MPH use in the context of careful SMD: -0.40 (95% medication monitoring shows good evidence for benefits for Cl, -0.61 to -0.18) symptoms for 14 months.

ATX is effective for ADHD symptoms and well tolerated over 12 months.

SOE: Insufficient Only one study of GXR monotherapy is available. It reports reduced ADHD symptoms and global improvement, although less than a fifth of participants completed 12 months.

Monitoring of cardiac status may be indicated since approximately 1% of participants showed EGG changes judged clinically significant.

Combined The results from 2 cohorts indicate both medication (MPH) and Psychostimulant

SOE: Low combined medication and behavioral treatment are effective in

Medication and SMD: -0.70 (95% treating ADHD plus ODD symptoms in children, primarily boys Behavioral ages 7-9 years of nomnal intelligence with combined type of Treatment

Cl, -0.95 to -0.46) ADHD, especially during the first 2 years of treatment.

Several reports from one high-quality study suggest that combined medication and behavioral treatment improves outcomes more than medication alone for some subgroups of children with ADHD combined type and for some outcomes.

Behavioral/ There is not enough evidence to draw conclusions for persons Psychosocial

SOE: Insufficient 6 years and older with a diagnosis of ADHD.

Parent Behavior There is not enough evidence to draw conclusions for persons Training

SOE: Insufficient 6 years and older with a diagnosis of ADHD.

Academic Interventions One good-quality study and its extension showed that classroom-based programs to enhance academic skills are effective in improving achievement scores in multiple domains, but following discontinuation, the benefits for sustained growth in academic skills are limited to the domain of reading fluency. All other domains show skill maintenance but not continued growth.

SOE: Insufficient

dextroamphetamine (DEX), or mixed amphetamine salts (MAS), effectively decrease the core symptoms of ADHD and associated impairment. 10 A review of the mechanisms of action of pharmacological interventions for ADHD is beyond the scope of this report. Some preparations last only a few hours, with symptoms returning as the medication wears off. Many families choose to use medication primarily on school days, and these medications have primarily been studied in school-aged children and youth aged 6 years and older. Psychostimulants, most connnonly MPH and DEX, are generally safe and well tolerated. Common side effects include poor appetite, insomnia, headaches, stomachaches, and increased blood pressure and heart rate. Prolonged use may result in a decreased rate of growth, generally considered clinically insignificant.n8 Concerns have been raised from postmarketing surveillance suggesting a rare incidence of sudden death, perhaps associated with pre-existing cardiac defects, however, the rate does not appear to exceed that of the base rate of sudden death in the population. 118 As noted earlier, approximately 2.5 million children in the United States, ages 4 to 17 years with a diagnosis of Attention Deficit Disorder (ADD) or ADHD, cunently take medication.4

Several extended release preparations of psychostimulants have been developed in recent years aimed at improved adherence and symptom control throughout the day as well as decreased abuse potential. 120 Non-stimulants (e.g., alpha adrenergic agents and atomoxetine (A TX)) have also been developed and found to be helpful in controlling symptoms with few adverse events. 121 However, in general, the benefits ofmedications wear offwhen they are discontinued. Since ADHD is a chronic disorder, many children, teens, and adults stay on medications for years at a time. Given the possibility of cumulative effects over time, a review of evidence regarding benefits and risks ofprolonged medication use for ADHD is indicated.

Nonpharmacological Interventions In the area of nonpharmacologic interventions, behavior training has been found to be

helpful, primarily for disruptive behaviors that frequently coincide with ADHD. 122 Since ADHD may begin before school age, using the precedent of older children, increasing numbers of preschoolers are being identified and treated, sometimes with medications. However, the most commonly used psychostimulant, MPH, does not yet have government regulatory approval for use in children less than 6 years of age, while MAS has been granted aEproval by the FDA in the United States for children under 6 years, but older than 3 years of age. 2 Recent reviews of treatments for preschoolers with ADHD emphasize the use ofparenting interventions prior to medication based on general clinical consensus. 124 Indeed, the Preschool ADHD Treatment Study (PATS), funded by the U.S. National Institute for Mental Health (NIMH), included parent behavior training (PBT) as the first phase for all children recruited into the study prior to randomization for the purpose of evaluating efficacy and safety ofpsychostimulant medication.125 While the few studies available suggest stimulant medications are effective for the core symptoms of inattention, hyperactivity, and impulsiveness in very young children, psychostimulants also appear to cause more adverse events in preschool children than in older children.54 Beyond the PATS, little information exists to document effectiveness of either medication or non-medication interventions specifically for ADHD in this age group. Part ofthe difficulty has been lack of clarity regarding reliability and validity of diagnostic criteria and therefore lack ofwidespread application of the ADHD diagnosis for children under 6 years.n 9
