Adults' perceptions of genetic counseling and genetic testing.

PURPOSE: This study described the perceptions of genetic counseling and testing of adults (N = 116) attending a genetic education program. Understanding perceptions of genetic counseling, including the importance of counseling topics, will contribute to patient-focused care as clinical genetic applications for common, complex disorders evolve. METHODS: Participants completed a survey addressing: the importance of genetic counseling topics, benefits and negative effects of genetic testing, and sharing test results. RESULTS: Topics addressing practical information about genetic conditions were rated most important; topics involving conceptual genetic/genomic principles were rated least important. The most frequently identified benefit and negative effect of testing were prevention/early detection/treatment and psychological distress. Participants perceived that they were more likely to share test results with first-degree than other relatives. CONCLUSIONS: Findings suggest providing patients with practical information about genetic testing and genetic contributions to disease, while also determining whether their self-care abilities would be enhanced by teaching genetic/genomic principles.

The evidence-based pharmacological treatment of paediatric ADHD.

Attention deficit hyperactivity disorder (ADHD) is common in children, adolescents, and adults, with extensive research establishing it as a valid neurobiological disorder. Without intervention, ADHD can result in significant impairment throughout the lifespan for the individuals it afflicts. Fortunately, multiple evidence-based options are available for the treatment of ADHD, including several efficacious pharmacotherapies. The role of medication, including stimulants as well as non-stimulants, is well-documented by an extensive body of literature. Although there may be less enthusiasm for behavioural and other psychosocial interventions as stand-alone treatments for moderate to severe ADHD, they are recommended as first-line treatment for ADHD management in preschool-aged children, for those patients with mild symptoms, and as an adjunct to medication in patients with comorbid disorders or suboptimal responses to pharmacotherapy. When planning treatment for individuals with ADHD, the potential risks associated with the available interventions must be carefully balanced against the risks of not treating, or not treating adequately. The treatment plan must also include ongoing re-assessment of the effectiveness of and the need for continued therapy. Recent practice parameters provide further specific guidance for the evidence-based assessment and treatment of children and adolescents with ADHD.

A double-blind, placebo-controlled study of atomoxetine in young children with ADHD.

OBJECTIVE: To evaluate the efficacy and tolerability of atomoxetine for the treatment of attention-deficit/hyperactivity disorder (ADHD) in 5- and 6-year-old children. METHODS: This was an 8-week, double-blind, placebo-controlled randomized clinical trial of atomoxetine in 101 children with ADHD. Atomoxetine or placebo was flexibly titrated to a maximum dose of 1.8 mg/kg per day. The pharmacotherapist reviewed psychoeducational material on ADHD and behavioral-management strategies with parents during each study visit. RESULTS: Significant mean decreases in parent (P = .009) and teacher (P = .02) ADHD-IV Rating Scale scores were demonstrated with atomoxetine compared with placebo. A total of 40% of children treated with atomoxetine met response criteria (Clinical Global Impression-Improvement Scale indicating much or very much improved) compared with 22% of children on placebo, which was not significant (P = .1). Decreased appetite, gastrointestinal upset, and sedation were significantly more common with atomoxetine than placebo. Although some children demonstrated a robust response to atomoxetine, for others the response was more attenuated. Sixty-two percent of subjects who received atomoxetine were moderately, markedly, or severely ill according to the Clinical Global Impression-Severity Scale at study completion. CONCLUSIONS: To our knowledge, this is the first randomized controlled trial of atomoxetine in children as young as 5 years. Atomoxetine generally was well tolerated and reduced core ADHD symptoms in the children on the basis of parent and teacher reports. Reductions in the ADHD-IV Rating Scale scores, however, did not necessarily translate to overall clinical and functional improvement, as demonstrated on the Clinical Global Impression-Severity Scale and the Clinical Global Impression-Improvement Scale. Despite benefits, the children in the atomoxetine group remained, on average, significantly impaired at the end of the study.

Review of pediatric attention deficit/hyperactivity disorder for the general psychiatrist.

Attention deficit/hyperactivity disorder (ADHD) is a common and impairing psychiatric condition, affecting significant numbers of children and adolescents. General psychiatrists serve, both by choice and out of necessity, in the assessment and treatment of children and adolescents who have ADHD and in the education of patients and their families. For many clinicians, however, there are numerous unanswered questions regarding the diagnosis and therapeutic interventions for ADHD. This article provides general psychiatrists with a practical overview and update on the assessment, diagnosis, and treatment of pediatric ADHD. Background information, recent relevant research, current evidence-based practice guidelines, and tips for clinical practice are reviewed in this article. The information is presented in a question-answer format.

Acute atomoxetine treatment of younger and older children with ADHD: a meta-analysis of tolerability and efficacy.

BACKGROUND: Atomoxetine is FDA-approved as a treatment of attention-deficit/hyperactivity disorder (ADHD) in patients aged 6 years to adult. Among pediatric clinical trials of atomoxetine to date, six with a randomized, double-blind, placebo-controlled design were used in this meta-analysis. The purpose of this article is to describe and compare the treatment response and tolerability of atomoxetine between younger children (6-7 years) and older children (8-12 years) with ADHD, as reported in these six acute treatment trials. METHODS: Data from six clinical trials of 6-9 weeks duration were pooled, yielding 280 subjects, ages 6-7 years, and 860 subjects, ages 8-12 years with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)-diagnosed ADHD. Efficacy was analyzed using the ADHD Rating Scale-IV (ADHD-RS), Conners' Parent Rating Scale-revised (CPRS-R:S), and the Clinical Global Impression of ADHD Severity (CGI-ADHD-S). RESULTS: Atomoxetine was superior to placebo in both age categories for mean (SD) change in ADHD-RS total, total T, and subscale scores; 3 CPRS-R:S subscales; and CGI-ADHD-S from baseline. Although there were no significant treatment differentials between the age groups for these efficacy measures, the age groups themselves, regardless of treatment, were significantly different for ADHD-RS total (younger: ATX = -14.2 [13.8], PBO = -4.6 [10.4]; older: ATX = -15.4 [13.2], PBO = -7.3 [12.0]; p = .001), total T (younger: ATX = -15.2 [14.8], PBO = -4.9 [11.2]; older: ATX = -16.4 [14.6], PBO = -7.9 [13.1]; p = .003), and subscale scores (Inattentive: younger: ATX = -7.2 [7.5], PBO = -2.4 [5.7]; older: ATX = -8.0 [7.4], PBO = -3.9 [6.7]; p = .043; Hyperactive/Impulsive: younger: ATX = -7.0 [7.2], PBO = -2.1 [5.4]; older: ATX = -7.3 [7.0], PBO = -3.4 [6.3]; p < .001), as well as the CGI-ADHD-S score (younger: ATX = -1.2 [1.3], PBO = -0.5 [0.9]; older: ATX = -1.4 [1.3], PBO = -0.7 [1.1]; p = .010). Although few subjects discontinued from either age group due to adverse events, a significant treatment-by-age-group interaction was observed for abdominal pain (younger: ATX = 19%, PBO = 6%; older: ATX = 15%, PBO = 13%; p = .044), vomiting (younger: ATX = 14%, PBO = 2%; older: ATX = 9%, PBO = 6%; p = .053), cough (younger: ATX = 10%, PBO = 6%; older: ATX = 3%, PBO = 9%; p = .007), and pyrexia (younger: ATX = 5%, PBO = 2%; older: ATX = 3%, PBO = 5%; p = .058). CONCLUSION: Atomoxetine is an effective and generally well-tolerated treatment of ADHD in both younger and older children as assessed by three recognized measures of symptoms in six controlled clinical trials. TRIAL REGISTRATION: Not Applicable.

Beyond the 'typical' patient: treating attention-deficit/hyperactivity disorder in preschoolers and adults.

Attention-deficit/hyperactivity disorder (ADHD), typically affects school-aged children, but can present during the preschool years and persist into adulthood. Accurate diagnosis for preschoolers and adults requires adaptation of the current diagnostic criteria to account for differences in symptomatology across the age span. The differential diagnosis of ADHD and the pattern of psychiatric comorbidity vary with each age group and complicate diagnosis and management. To maximize outcomes clinicians must be able to accurately identify ADHD across the lifespan, and develop comprehensive, collaborative treatment plans. The Preschool ADHD Treatment Study (PATS) demonstrated the potential utility of methylphenidate for treating ADHD in preschoolers, and trials of psychostimulants and atomoxetine have shown some benefits for adults. Behavioural interventions likely have an adjunctive role in ADHD treatment for both groups. More research, however, is needed to determine the safest and most effective pharmacotherapies and psychosocial interventions for these non-typical patients.

Assessing the efficacy of treatments for ADHD : overview of methodological issues.

Attention-deficit hyperactivity disorder (ADHD) is a common and impairing psychiatric condition that affects significant numbers of children, adolescents and adults. Clinicians in a variety of practice settings (hospital, outpatient, residential, research) strive to diagnose, treat and monitor ADHD in an efficient and evidence-based manner. Tools that facilitate the gathering and interpretation of information from a variety of sources can effectively augment a diagnostic assessment, and can also be useful for longitudinal monitoring. Multiple assessment tools are available, with varying degrees of psychometric validity, clinical utility and overall feasibility (time and cost). This review provides an overview of several available ADHD rating scales and continuous performance tests, and offers a discussion of potential strengths and weaknesses of the instruments. While these tools do not in and of themselves make a diagnosis of ADHD, they can certainly assist in the diagnostic assessment, be crucial in assessing the efficacy of medications in clinical trials, and be a useful adjunct in the clinical management of ADHD.

Attention deficit hyperactivity disorder in preschool children.

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder with a childhood onset of symptoms and impairment. Although it is most frequently identified during elementary school years, epidemiologic data suggest that the onset of ADHD frequently occurs earlier, with presentation as young as 3 years of age. Early identification, however, allows consideration of appropriate interventions. Many data are available on safe and efficacious treatment options for school-aged children who have ADHD; however, little is known about the use of these modalities in preschoolers and, ultimately, the long-term effects of early treatment. Recognition of the preschool presentation of ADHD, appropriate differential diagnosis, and identification of comorbid conditions, and a developmental perspective on the course and potential outcomes of the disorder may guide treatment planning. Newly available data on the safety and efficacy of pharmacotherapy and psychosocial intervention for preschoolers who have ADHD may help clinicians make treatment decisions for these young children and their families.

Ethics and the prescription pad.

This article reviews the considerations that inform ethical psychotropic medication prescription processes at the clinical level with child and adolescent patients and their families or guardians. Physician attributes, cultural and religious factors, and the psychodynamic aspects of psychopharmacology are reviewed, in addition to the applications of basic ethical principles and concepts to the act of dispensing psychotropic medications. Attention is given to the processes of informed consent, assent, and challenges encountered to ethical prescribing for special populations such as children in foster care and juvenile justice systems. Ramifications of black box warnings and off label prescribing are discussed. Finally, the authors offer practical tips to guide clinicians in ethical psychopharmacologic management of their child and adolescent patients.

A pilot study of atomoxetine in young children with attention-deficit/hyperactivity disorder.

OBJECTIVE: The purpose of this study was to assess the effectiveness and tolerability of atomoxetine during acute treatment of attention-deficit/hyperactivity disorder (ADHD) in 5 and 6 year olds. METHOD: Twenty two children (male n = 19, 86%) with ADHD were treated with atomoxetine for 8 weeks in a three-site, open-label pilot study. Dosing was flexible, with titration to a maximum of 1.8 mg/kg per day. Parent education on behavior management was provided as part of each pharmacotherapy visit. RESULTS: Subjects demonstrated a mean decrease of 20.68 points (SD = 12.80, p < 0.001)) on the ADHD Rating Scale-IV (ADHD-IV-RS) total score, 10.18 (SD = 7.48, p < 0.001) on the inattentive subscale and 10.50 (SD = 7.04, p < 0.001) on the hyperactive/impulsive subscale. Clinical Global Impression-Severity (CGI-S) was improved in 82% of the children (95% CI, 66-98%) and Children's Global Assessment (CGAS) scores improved 18.91 points on average (SD = 12.20, p < 0.001). The mean final dose of atomoxetine was 1.25 mg/kg per day (SD = 0.35 mg/kg per day). Mood lability was the most commonly reported adverse event (n = 12, 54.5%). Eleven subjects (50%) reported decreased appetite and a mean weight loss of 1.04 kg (SD = 0.80 kg) (p < 0.001) was observed for the group. Vital sign changes were mild and not clinically significant. There were no discontinuations due to adverse events or lack of efficacy. CONCLUSION: Atomoxetine was generally effective for reducing core ADHD symptoms in the 5 and 6 year olds in this open-label study.

Atomoxetine in the management of children with ADHD: effects on quality of life and school functioning.

The purpose of this study was to examine in a controlled trial the effects of atomoxetine on the management of attention deficit-hyperactivity disorder (ADHD) symptoms and functional impairments at school and at home. Participants were 153 children (age 8 to 12 years) diagnosed with attention-deficit hyperactivity disorder who were randomized to double-blind treatment with either atomoxetine (n = 101) or placebo (n = 52). Findings revealed significant improvements both for parent and teacher ratings of behavior for children receiving atomoxetine therapy. Children also were reported to evidence a trend toward better response to active medication than to placebo for health-related quality of life as rated by parents. No significant effects were revealed for the teacher ratings of academic productivity. Data were interpreted to provide support for the efficacy of atomoxetine on the symptoms associated with ADHD. The effects of atomoxetine on other functional outcomes including academic performance and health-related outcomes are of interest, albeit less compelling for this particular investigation, than for the effects on overt symptom display.

Atomoxetine treatment in children and adolescents with attention-deficit hyperactivity disorder: what are the long-term health-related quality-of-life outcomes?

OBJECTIVE: Numerous investigations have examined the efficacy of pharmacological treatment for attention-deficit/hyperactivity disorder (ADHD) in children. However, relatively few studies have addressed the impact of treatment on long-term subjective, psychosocial outcomes, such as health-related quality of life (HRQL). This study examines the long-term effects of pharmacological treatment with atomoxetine on HRQL in children and adolescents with ADHD. METHODS: Participants included 6- to 17-year-old children and adolescents (n = 912) with ADHD enrolled in a 24-month, multicenter, open-label trial of atomoxetine. Outcomes included clinician ratings of ADHD, parent ratings of ADHD, and a widely used measure of HRQL (The Child Health Questionnaire (CHQ)). Treatment response rates were calculated based on a CHQ improvement of at least 1 standard error of measurement. RESULTS: Significant improvements in HRQL were found following both acute and long-term treatment for psychosocial but not physical health. Of participants who completed treatment (n = 312 or 34.2% of those enrolled), 81% responded to acute treatment and 78% responded to long-term treatment. Improvements noted after acute treatment were maintained during long-term treatment with the majority of participants (86%) continuing to respond to treatment. CONCLUSIONS: Atomoxetine is associated with improvements in HRQL, and the improvements are generally stable over time.

Pharmacotherapy of ADHD in young children.

Attention-deficit hyperactivity disorder (ADHD) is a disorder common throughout childhood, with recognizable symptoms as early as preschool in many cases. ADHD is often treated in young children by simply implementing strategies proven efficacious and safe in older children and adolescents, as limited data is available in children younger than age six. Research has been extended into this age group by the Preschool ADHD Treatment Study (PATS) and other recent trials, providing clinically relevant data on differences in tolerability and efficacy of ADHD pharmacotherapies, primarily methylphenidate. No published data is yet available on the use of atomoxetine in children under age six. Growth is an area of particular interest and concern in the pediatric population, with data demonstrating variability in the long-term rates of growth in height as well as weight. While pharmacotherapy holds the potential for significant benefit in young children with ADHD, concerns with variation in response and tolerability highlight the need for careful evaluation, close monitoring, and an ongoing risk/benefit analysis throughout the implementation and use of medication.

The role of stimulants in the treatment of preschool children with attention-deficit hyperactivity disorder.

The symptoms of attention-deficit hyperactivity disorder (ADHD) can have an early onset, beginning before the age of 6 years. Despite the significant number of preschool-aged children that can be diagnosed with ADHD, there are limited controlled data available on the pharmacological interventions being increasingly used in this population. A 1990 review showed that 34% of paediatricians and 15% of family physicians had prescribed psychostimulant medications to preschoolers with ADHD, and pharmacoepidemiological studies indicate growing use of stimulants in preschoolers during the 1990s. Unfortunately, only six controlled trials, with a total enrollment of less than 200 children, have been conducted using these drugs in preschoolers. While these small studies provide some evidence of benefit from the use of methylphenidate in preschoolers with ADHD, more data are critically needed. Practice parameters developed by the American Academy of Child & Adolescent Psychiatry and the American Academy of Pediatrics provide some guidance regarding the diagnosis and treatment of young children with ADHD, but are mainly based upon research in children of primary-school age. The ongoing PATS (Preschool ADHD Treatment Study), funded by the National Institute of Mental Health, will provide important clinical guidance for diagnostic considerations and intervention strategies for children with ADHD aged 3-5 years. Pending the release of data from the PATS study, clinicians must rely on developmental assessment skills, available standardised rating instruments, reports about the child from multiple informants, and knowledge of the risks and benefits of available pharmacological and behavioural treatments, in order to treat preschool children with ADHD effectively.

Atomoxetine in the treatment of attention deficit hyperactivity disorder.

Atomoxetine (Strattera, Eli Lilly & Co.) is a highly selective noradrenaline reuptake inhibitor and the first nonstimulant medication to be approved for the treatment of attention deficit hyperactivity disorder. Currently, nine published clinical trials have documented the safety and efficacy of atomoxetine in the treatment of children, adolescents and adults with attention deficit hyperactivity disorder and data presented throughout the past year at national scientific meetings has further addressed its utility. This article reviews the available information on atomoxetine, accompanied by a discussion of its clinical use.

Atomoxetine: a selective noradrenaline reuptake inhibitor for the treatment of attention-deficit/hyperactivity disorder.

Atomoxetine (Strattera, Eli Lilly & Co.) is a selective noradrenaline reuptake inhibitor that has been studied for use in the treatment of attention-deficit/hyperactivity disorder (ADHD). So far, two open-label and seven randomised, double-blind, placebo-controlled, clinical trials have been published, six in youths and three in adults. Each of these trials has shown a positive response as measured by the primary efficacy measures, the ADHD-IV Rating Scale (ADHD RS) or the Conners Adult ADHD Rating Scale (CAARS). Atomoxetine has generally been well tolerated. In November of 2002 the FDA approved atomoxetine for use in the US for the treatment of ADHD in children, adolescents and adults. Atomoxetine is the first nonstimulant approved by the FDA for the treatment of ADHD and the first medication approved for the treatment of adult ADHD.
