RESUMEN

Underlying deficits in inattention, hyperactivity, and/or impulsivity might contribute to suboptimal test-taking behaviours during language assessments that can lead to diagnostic errors. Considerations of potential medication effects on estimates of children's nonword repetition, sentence recall, tense-marking, and narrative abilities are warranted given long-standing enthusiasm for these indices to serve as clinical markers for developmental language disorder (DLD). A battery consisting of 1 nonverbal, 1 reading, and 6 verbal measures was administered twice to 26 children (6-9 years) with independently diagnosed combined-type attention-deficit/hyperactivity disorder (ADHD). All participants had been prescribed stimulant medications for the management of their ADHD symptoms and were assessed off- and on-medication, with order counter-balanced across participants. Half of the participants had concomitant DLD. Examiners were unaware of children's clinical status during assessments or when they were testing children who had received medication. Effect sizes were calculated for each measure. Significant score differences indicating a beneficial impact of stimulant medications on children's performances were observed on the recalling sentences subtest of the Clinical Evaluation of Language Fundamentals and the Picture Peabody Vocabulary Test. Adjustments may be needed when speech language pathologists use sentence recall or receptive vocabulary measures to make diagnostic decisions with children who have ADHD.

RESUMEN

Background: Recent studies indicate that COVID-19 has had a significant impact on access and continuity to opioid and benzodiazepine medications; little is known about its effect on access to and utilization of stimulant medications. Objective: To investigate trends of dispensed stimulant medications in relation to the COVID-19 pandemic response. Methods: Stimulant prescriptions dispensed during 2011-2021 were analyzed using the Massachusetts Prescription Drug Monitoring Program (PDMP), the state's data repository for all controlled substance medications dispensed to residents from retail pharmacies and out of state mail-order pharmacies. Statewide trends were estimated by age group, sex, and stimulant-naïve patients (individuals with no stimulant prescription in the prior one-year period). Results: Overall, stimulant prescriptions increased 70% from 2011 to 2021. Wide differences by sex and age groups were found pre and post COVID response periods. Between 2019 and 2021, stimulant prescriptions for males 12-18 years old decreased 14.6% compared to 0.9% for females. Female stimulant-naïve patients ages 25-34 increased more than males between 2019 and 2021 (11.6% compared to <1%, respectively) and females ages 35-44 increased 4.1% while males decreased by 2.7%. Conclusions: Administrators, clinicians, and policy makers should closely monitor stimulant prescribing trends, a critical step in improving access to and quality of care.

RESUMEN

Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder with onset usually in childhood characterized by inattention, impulsivity, and hyperactivity causing a functional impairment. Untreated ADHD, or treatment delay is associated with adverse outcomes and poor quality of life. Although conservative management strategies such as behavioral and psychological interventions are important, pharmacological treatment has a strong evidence base with improved outcomes. ADHD medications are broadly divided into stimulant and non-stimulant medications. Stimulant medications are generally more effective than non-stimulants. Cardiovascular safety of ADHD medication has been a matter of debate for decades. Treatment guidelines advise the careful consideration of risks and benefits in people with cardiovascular diseases such as congenital heart disease or cardiomyopathy. Although stimulants can increase systemic blood pressure and heart rate, no significant associations were found between their use and serious cardiovascular events. Concerns regarding QT effects and attendant sudden cardiac death risks deter clinicians from initiating much-needed ADHD medications in patients with heart disease. This overly cautious approach is potentially depriving low-risk individuals from significant benefits associated with timely ADHD drug treatment. This review discusses the cardiovascular risks reportedly associated with ADHD medications, the evidence base for their safe usage in persons with established cardiovascular disease, and highlights future research directions.

RESUMEN

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that interferes with multiple aspects of daily functioning. Malingering or feigning of symptoms can be a major challenge during ADHD assessment. Stimulant medication abuse, misuse and diversion may constitute another challenge during management. A literature search of the past 15 years on the topic continued to suggest that there are several reasons for malingering and faking ADHD symptoms. Some of the reasons include the intent to obtain prescriptions for stimulant medications for performance enhancement, to gain access to additional school services and accommodations, to use recreationally and to sell as a street drug. In some countries, patients may receive additional tax or student loan benefits. Several researchers suggested that self-report rating measures are easily simulated by patients without ADHD. They concluded that no questionnaire has proved sufficiently robust against false positives. Some clinical factors that may suggest malingering during the ADHD assessment are highlighted and some available tests to detect malingering are discussed.

RESUMEN

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental conditions among school-age children. Early intervention and ongoing evaluation of treatment effectiveness are essential to minimize the life-long negative impact of ADHD. Neurocognitive functions have been reported to improve with pharmacological and cognitive training interventions for children with ADHD. We evaluated the value of measuring change in neurocognitive functions following ADHD interventions as a treatment outcome. We systematically reviewed randomized control trials of two distinctive types of ADHD interventions-pharmacological treatments and cognitive training-and summarized the changes in neurocognitive and clinical outcomes using a series of meta-analyses. Both pharmacological and cognitive training interventions showed positive effects on some aspects of neurocognitive functions. However, there were no significant correlations between changes in neurocognitive function (e.g., inhibition) and changes in ADHD behavioral symptoms (e.g., impulsive behavior). Although the associations between changes in neurocognitive function and clinical outcomes are not well studied, based on current findings, it is not suitable to use change in neurocognitive outcomes as a proxy for change in ADHD clinical symptom-based outcomes. There is, however, notable value in monitoring changes in neurocognitive function associated with ADHD interventions to achieve the following aims: (1) understanding full treatment effect on children with ADHD, (2) identifying ancillary indicators of subclinical changes, and (3) provision of objective and less biased measures of treatment effects. These findings are important evidence that changes in neurocognitive function could be a co-occurring objective indication that parallels the clinical effects of ADHD treatments.

RESUMEN

BACKGROUND: Individuals with trichotillomania (TTM), a disorder characterized by repetitive pulling out of one's own hair, often have co-occurring ADHD, but little is known about this comorbidity. Additionally, there have been intimations in the literature that treatment of ADHD with stimulants may worsen TTM symptoms. This study aims to examine clinical aspects of individuals with TTM and co-occurring ADHD. METHODS: 308 adults with a current diagnosis of TTM were assessed for ADHD using the Mini International Neuropsychiatric Interview 7.0.2 and Adult ADHD Self Report Scale. Participants also completed clinical measures related to TTM severity, impulsivity, quality of life, and psychosocial dysfunction. A series of analyses of variance were used to calculate differences in scale scores among subjects with and without co-occurring ADHD. RESULTS: Of the 308 participants, 47 (15.3%) met the clinical threshold for ADHD. Participants with ADHD reported significantly higher scores in all first and second factor traits of impulsivity, including attentional impulsiveness (p < .0001), motor impulsiveness (p < .0001), and non-planning impulsiveness (p < .0001). Interestingly, participants with ADHD did not report significant differences in TTM severity, perceived quality of life, or functional impairment, regardless of medication status. DISCUSSION: The data suggest that ADHD is common in adults with TTM, and the comorbidity is associated with heightened impulsivity. The co-occurrence of ADHD does not affect individuals' quality of life, symptom severity, or functionality. Taking stimulant medications for ADHD also did not appear to affect TTM severity, despite past case reports suggesting these medications may lead to onset or worsening of TTM.

RESUMEN

PURPOSE: Anorexia and weight loss are common complications in the elderly, advanced cancer population. Appetite stimulants are commonly used therapies for oncology patients with weight loss, yet their safety comparison remains unknown. METHODS: This was a two-center, retrospective, study conducted in New York City at Mount Sinai Beth Israel and New York University Langone from January 2016 to July 2019 in adult patients with histologic evidence of malignancy who were taking either megestrol acetate or mirtazapine as an appetite-stimulating medication. Endpoints included safety concerns of mortality, QTc prolongation, venous thromboembolism, fall, somnolence, xerostomia, and hallucinations. Effectiveness of weight gain or maintenance of weight was not assessed. A propensity score-matching analysis was performed using a logistic regression analysis to assess the two comparable groups. RESULTS: The study included 350 patients (69.56 ± 13.31 years) with the most common malignancies being gastrointestinal, breast, and hematologic with metastasis present in over half the patients. Adverse events were commonly seen in the oncology population. After a propensity score-matched analysis, all safety outcomes associated with mirtazapine compared to megestrol acetate were similar; all-cause mortality (7%, n = 7 vs. 12%, n = 12, p = 0.23), QTc prolongation (31%, n = 31 vs. 31%, n = 31, p = 1.00), thromboembolism (11%, n = 11 vs. 11%, n = 11, p = 1.00), somnolence (29%, n = 30 vs. 22%, n = 23, p = 0.34), xerostomia (27%, n = 28 vs. 18%, n = 19, p = 0.24), and hallucinations (17%, n = 18 vs. 8%, n = 8, p = 0.06), respectfully. CONCLUSION: There were no safety differences seen when evaluating both agents.

RESUMEN

BACKGROUND: Children with attention-deficit/hyperactivity disorder (ADHD) often exhibit behaviour challenges and deficits in executive functions (EF). Psychostimulant medications [e.g., methylphenidate (MPH)] are commonly prescribed for children with ADHD and are considered effective in 70% of the cases. Furthermore, only a handful of studies have investigated the long-term impact of MPH medication on EF and behaviour. AIM: To evaluate behaviour and EF challenges in children with ADHD who were involved in an MPH treatment trial across three-time points. METHODS: Thirty-seven children with ADHD completed a stimulant medication trial to study the short- and long-term impact of medication. Children with ADHD completed three neuropsychological assessments [Continuous Performance Test (CPT)-II, Digit Span Backwards and Spatial Span Backwards]. Parents of children with ADHD completed behaviour rating scales [Behaviour Rating Inventory of Executive Functioning (BRIEF) and Behaviour Assessment System for Children-Second Edition (BASC-2)]. Participants were evaluated at: (1) Baseline (no medication); and (2) Best-dose (BD; following four-week MPH treatment). Additionally, 18 participants returned for a long-term naturalistic follow up (FU; up to two years following BD). RESULTS: Repeated measure analyses of variance found significant effects of time on two subscales of BRIEF and four subscales of BASC-2. Neuropsychological assessments showed some improvement, but not on all tasks following the medication trial. These improvements did not sustain at FU, with increases in EF and behaviour challenges, and a decline in performance on the CPT-II task being observed. CONCLUSION: Parents of children with ADHD reported improvements in EF and behaviours during the MPH trial but were not sustained at FU. Combining screening tools and neuropsychological assessments may be useful for monitoring medication responses.

RESUMEN

Introducción: El metilfenidato (MTF) es un psicoestimulante que aumenta frecuencia cardiaca (FC) y presión arterial (PA), lo cual a largo plazo podría modificar la geometría del ventrículo izquierdo (VI) y alterar sus propiedades funcionales, principalmente la diastólica. Material y métodos: Estudio prospectivo, longitudinal y comparativo tipo caso-caso en niños y adolescentes sanos diagnosticados de trastorno por déficit de atención e hiperactividad (TDAH) tratados con MTF durante 3 años. Se valoró pre y postratamiento PAS/PAD, geometría ventricular, función sistólica y diastólica. Resultados: Incluimos a 112 pacientes, completando 73. El 75,3% varones, entre 4-15 años (9±2,6), con índice de masa corporal de 18,27±3,75 y una dosis media de MTF de 0,9±0,17mg/kg/día. Objetivamos aumento de PAS/PAD de 3,7±9mmHg (p = 0,004) y 2±11,5mmHg, respectivamente. No tuvimos ningún evento cardiovascular grave, cambios estructurales ni variación en los parámetros de función sistólica estudiados. Sin embargo, encontramos un aumento discreto, pero progresivo y significativo del tiempo de relajación isovolumétrica del VI (p = 0,046) y del tiempo de desaceleración (p = 0,016) indicativos de alteración en la relajación. No observamos variación en los parámetros relacionados con la distensibilidad ni con las presiones diastólicas tempranas y ningún paciente cumplió criterios de disfunción diastólica. Conclusiones: El incremento de PAS/PAD y las alteraciones de la relajación del VI objetivadas podrían ser un indicador precoz de una posible disfunción diastólica y riesgo cardiovascular a largo plazo.(AU)

Introduction: Although methylphenidate (MPH) used for treatment of Attention deficit hyperactivity disorder (ADHD) are considered safe in healthy children and adolescents in the short and medium term, there is a widespread concern about long-term cardiovascular safety. Material and methods: Interventional, prospective, longitudinal and comparative study with a crossover design to evaluate the cardiovascular impact of the treatment with MPH in healthy children and adolescents diagnosed with ADHD. A protocol for the cardiovascular evaluation was established at a basal point, after the first and the second year of the beginning with treatment based on the monitoring of Blood pressure (BP) and echocardiographic follow-up of the systolic and diastolic functions, and structural cardiac properties. Results: 73 patients completed the study, with an average age of 9+/- 2.6 years, 75.3% were male and the majority were thin (64.4%). We found an increase in Systolic and Diastolic BP of 3.7±9mmHg (P).004) and 2±11,5mmHg respectively. There were no severe cardiovascular events. We didn’t find any echocardiographic alterations namely on the structural properties or parameters of systolic function. Regarding diastolic function, a significant increase in the isovolumic relaxation time (IVRT) (P=.046) and deceleration time (P=.016) was observed. However, no significant alterations in the parameters related to distensibility of the LV neither in the early diastolic pressure were found. Conclusion: Further studies are needed to evaluate the impact of psychostimulants as a modifiable long-term Cardiovascular Risk Factor.(AU)

RESUMEN

BACKGROUND: There are claims that ocular accommodation differs in children with attention deficit hyperactivity disorder (ADHD) compared to typically developing children. We examined whether the accommodation response in ADHD children is influenced by changing the stimulus to accommodation in an attempt modify the level of attentional engagement or by medication for the condition. METHODS: We measured the accommodative response and pupil diameter using a binocular, open-field autorefractor in non-medicated and medicated children with ADHD (n = 22, mean age = 10.1 ± 2.4 years; n = 19; mean age = 11.0 ± 3.8 years; respectively) and in an age-matched control group (n = 22; mean age = 10.6 ± 1.9 years) while participants were asked to maintain focus on (i) a high-contrast Maltese cross, (ii) a frame of a cartoon movie (picture) and (iii) a cartoon movie chosen by the participant. Each stimulus was viewed for 180 s from a distance of 25 cm, and the order of presentation was randomised. RESULTS: Greater lags of accommodation were present in the non-medicated ADHD in comparison to controls (p = 0.023, lags of 1.10 ± 0.56 D and 0.72 ± 0.57 D, respectively). No statistically significant difference in the mean accommodative lag was observed between medicated ADHD children (lag of 1.00 ± 0.44D) and controls (p = 0.104) or between medicated and non-medicated children with ADHD (p = 0.504). The visual stimulus did not influence the lag of accommodation (p = 0.491), and there were no significant group-by-stimulus interactions (p = 0.935). The variability of accommodation differed depending on the visual stimulus, with higher variability for the picture condition compared to the cartoon-movie (p < 0.001) and the Maltese cross (p = 0.006). In addition, the variability yielded statistically significant difference for the main effect of time-on-task (p = 0.027), exhibiting a higher variability over time. However, no group differences in accommodation variability were observed (p = 0.935). CONCLUSIONS: Children with ADHD have a reduced accommodative response, which is not influenced by the stimulus to accommodation. There is no marked effect of medication for ADHD on accommodation accuracy.

RESUMEN

Pharmacotherapy of psychiatric illnesses in children and adolescents has grown significantly over the last few decades. However, the body of research examining pharmacological treatments for psychiatric illnesses is much smaller in children and adolescents than it is in adults. As most treatments for psychiatric disorders are more effective if started early in the course of illness, treatment options for youth are especially important in order to ensure better treatment outcomes. This chapter discusses currently approved medications to treat psychiatric disorders in children and adolescents. Research on medications that may be effective treatments but are not yet FDA approved is also discussed. The medications are broken down into major categories used in youth with psychiatric disorders including antidepressants, mood stabilizers, ADHD medications, and antipsychotics.

RESUMEN

Stimulant medications for the treatment of attention deficit hyperactivity disorder (ADHD) and inhaled corticosteroids (ICS) for the treatment of asthma are two classes of medications that are commonly prescribed in pediatrics. Among other adverse effects of these medications, growth attenuation has long been a focus of investigation. With stimulants, growth deficits of 1-1.4 cm/year have been observed in the short term, mainly in the first 2 years of treatment, in a dose-dependent manner. Long-term studies on stimulants have reported divergent effects on growth, with many studies showing no clinically significant height deficits by adulthood. The study that followed the largest cohort of children on stimulants, however, reported an overall adult height deficit of 1.29 cm in subjects who had received stimulant medications, with mean adult height deficit of 4.7 cm among those taking the medication consistently. With ICS use, mild growth suppression is seen in the short term (particularly in the first year of therapy) with growth rates reduced by 0.4-1.5 cm/year. Available current evidence indicates that the impact of ICS use on adult height is not clinically significant, with effects limited to 1.2 cm or less. There is significant individual variability in growth suppression with ICS use, with the specific pharmacologic agent, formulation, dose exposure, age, puberty, medication adherence, and timing of administration being important modifying factors. Based on currently available evidence, the therapeutic benefits of ICS for management of asthma and stimulant medications for management of ADHD outweigh the potential risk for growth suppression. Strategies to minimize growth attenuation and other potential adverse effects of these medications include using the lowest efficacious dose, frequent assessments and dose titration. Particular vigilance is essential with concomitant use of multiple medications that can attenuate growth and to evaluate for potential adrenal insufficiency from ICS use.

RESUMEN

INTRODUCTION: Attention Deficit Hyperactivity Disorder (ADHD) is a common comorbid condition in children with epilepsy and migraine. Treatment of ADHD in children with epilepsy or migraine is essential but clinicians may overlook symptoms of ADHD and avoid appropriate use of medications that may reduce symptoms of ADHD without compromising treatment of epilepsy or migraine. Areas covered: PubMed was searched for articles on ADHD and epilepsy or migraine. Key papers were reviewed for additional articles. Areas of interest were: epidemiology, etiological factors, and treatment with emphasis on therapy. Expert commentary: Stimulant medication, especially methylphenidate, appears to be safe and effective in the treatment of ADHD in children with epilepsy or migraine. Unfortunately, data is limited with very few controlled trials of methylphenidate and very limited information on the use of amphetamines or non-stimulant drugs.

RESUMEN

OBJECTIVE: Families of children with autism spectrum disorder are barraged by different treatment options. Some of these options have the support of empirical evidence while others do not. Stimulant treatments are typically utilized to treat symptoms of ADHD indicating an on-label use of such treatment. METHODS: This study examines the association of stimulant treatment with the on- (symptoms of ADHD) and off- (symptoms of ASD) label symptoms among children with ASD via a non-clinical, population-based sample. RESULTS: Results indicate no significant association of stimulant treatment with a reduction of on- or off-label symptoms among children with ASD. CONCLUSION: Stimulant medications utilized in the treatment of DSM core symptoms of autism spectrum disorder would be considered an off-label use because there is limited evidence to support that stimulants are effective in treating core symptoms of ASD, which is supported by the results of the current study.

RESUMEN

BACKGROUND AND OBJECTIVE: There is ongoing concern that stimulant medications may adversely affect growth. In a sample of attention-deficit/hyperactivity disorder (ADHD) cases and controls from a population-based birth cohort, we assessed growth and the association between stimulant treatment and growth. METHODS: Subjects included childhood ADHD cases (N = 340) and controls (N = 680) from a 1976 to 1982 birth cohort (N = 5718). Height and stimulant treatment information were abstracted from medical records and obtained during a prospective, adult follow-up study. For each subject, a parametric penalized spline smoothing method modeled height over time, and the corresponding height velocity was calculated as the first derivative. Peak height velocity (PHV) age and magnitude were estimated from the velocity curves. Among stimulant-treated ADHD cases, we analyzed height Z scores at the beginning, at the end, and 24 months after the end of treatment. RESULTS: Neither ADHD itself nor treatment with stimulants was associated with differences in magnitude of PHV or final adult height. Among boys treated with stimulants, there was a positive correlation between duration of stimulant usage before PHV and age at PHV (r = 0.21, P = .01). There was no significant correlation between duration of treatment and change in height Z scores (r = -0.08 for beginning vs end change, r = 0.01 for end vs 24 months later change). Among the 59 ADHD cases treated for ≥3 years, there was a clinically insignificant decrease in mean Z score from beginning (0.48) to end (0.33) of treatment (P = .06). CONCLUSIONS: Our findings suggest that ADHD treatment with stimulant medication is not associated with differences in adult height or significant changes in growth.

RESUMEN

BACKGROUND: Current data are limited on compliance with guidelines for the treatment of attention deficit/hyperactivity disorder (ADHD). METHODS: A survey assessing compliance with ADHD guidelines for diagnosis and management was distributed to pediatricians in a practice research network. Comparisons were made by practitioner characteristics. RESULTS: In all, 42/76 surveys were returned (55%). Respondents largely adhered to American Academy of Pediatrics (AAP) guidelines. A lower percentage reported compliance for rescreening with a standardized tool (80%), use of electrocardiograms (78% rarely use), and the use of routine additional testing (80% rarely use). Academic practitioners were more likely to rescreen (100% vs 79%, P < .05). Private practitioners more often used newer therapeutic agents (7% vs 44%, P < .01). Older graduates were more comfortable diagnosing at a young age (93% vs 56%, P < .01) and were more comfortable using sleep agents (60% vs 15%, P < .01). CONCLUSION: Pediatricians largely adhered to AAP guidelines. These findings support changes made to the guidelines in 2011. Differences in practice patterns exist by practitioner experience, location, and practice type.

RESUMEN

OBJECTIVE: To examine recent national trends in psychotropic use for very young children at US outpatient medical visits. METHODS: Data for 2- to 5-year-old children (N = 43 598) from the 1994-2009 National Ambulatory and National Hospital Ambulatory Medical Care Surveys were used to estimate the weighted percentage of visits with psychotropic prescriptions. Multivariable logistic regression was used to identify factors associated with psychotropic use. Time effects were examined in 4-year blocks (1994-1997, 1998-2001, 2002-2005, and 2006-2009). RESULTS: Psychotropic prescription rates were 0.98% from 1994-1997, 0.83% from 1998-2001, 1.45% from 2002-2005, and 1.00% from 2006-2009. The likelihood of preschool psychotropic use was highest in 2002-2005 (1994-1997 adjusted odds ratio [AOR] versus 2002-2005: 0.67; 1998-2001 AOR versus 2002-2005: 0.63; 2006-2009 AOR versus 2002-2005: 0.64), then diminished such that the 2006-2009 probability of use did not differ from 1994-1997 or from 1998-2001. Boys (AOR versus girls: 1.64), white children (AOR versus other race: 1.42), older children (AOR for 4 to 5 vs 2 to 3 year olds: 3.87), and those lacking private insurance (AOR versus privately insured: 2.38) were more likely than children from other groups to receive psychotropic prescriptions. CONCLUSIONS: Psychotropic prescription was notable for peak usage in 2002-2005 and sociodemographic disparities in use. Further study is needed to discern why psychotropic use in very young children stabilized in 2006-2009, as well as reasons for increased use in boys, white children, and those lacking private health insurance.

RESUMEN

OBJECTIVE: To study the characteristics of children diagnosed with attention-deficit/hyperactivity disorder (ADHD) in Australia, and the assessment and management practices of their pediatricians. METHODS: A 2-week practice audit was conducted in a large representative sample of Australian general/community pediatricians. Pediatricians completed an audit form for all patients seen. Demographic details, diagnoses, treatments, and referrals made were recorded for each consultation. RESULTS: A total of 199 pediatricians completed the audit (response rate 66%). There were 1528 consultations with patients with ADHD. Eighty percent of the subjects were male, and mean age at diagnosis was 9.1 years (range 3-19 years). Most patients (60%) had 1 or more comorbidity identified, although the reported rates of anxiety (8%) and oppositional defiant disorder (15%) were lower than expected. Patients with ADHD were more likely than patients with other diagnoses to be seen in private practice settings (76% vs. 65%; P < .001). Children with ADHD were referred to numerous services at diagnosis, most commonly psychology (32%). Stimulant medication or atomoxetine was prescribed for 40% at initial diagnosis and 80% at continuing consultation. Overall, methylphenidate was the most common medication prescribed (63%), with a minority prescribed dexamphetamine, atomoxetine, or clonidine. Eighteen percent were prescribed 2 or more medications. Medication prescription was predicted by age but not by gender or socioeconomic status. CONCLUSIONS: ADHD is the most frequent diagnosis seen by Australian pediatricians, with some patients being seen into early adult life. Comorbidities appear to be inconsistently identified, with some possibly underdiagnosed. Older children are more likely to be prescribed medication.
