Attention-deficit/hyperactivity disorder in children and adolescents: closing diagnostic, communication, and treatment gaps

The association between nonpharmacological interventions and quality of life in children with attention deficit hyperactivity disorder: A systematic review

BACKGROUND

Attention deficit hyperactivity disorder is a common psychiatric disorder with a worldwide prevalence of about five percent among children and adolescents. This disorder affects most aspects of their lives e.g., academic performance and social relations, and their overall quality of life is reduced compared to healthy peers. The majority of children with ADHD are treated with medication that potentially has an insufficient effect and/or frequently occurring side effects.

OBJECTIVES

To enable nurses and other health care professionals to guide children with ADHD and their families in their choices of treatment, based on the best available literature on the association between nonpharmacological interventions and quality of life.

DATA SOURCES

A literature search was performed in the databases CENTRAL, Embase, PubMed, CINAHL, and PsycINFO. Seven randomized controlled trials were included in this systematic review. They examined the use of polyunsaturated fatty acids, physical activity, psychoeducation, cognitive therapy, cognitive training, hippotherapy, and behavioral therapy.

CONCLUSIONS

The study of behavioral therapy in the form of a sleep intervention detected an improvement in quality of life which was statistically significant compared to the control group.

IMPLICATIONS FOR PRACTICE

Children with ADHD and a sleep disorder may gain improvement in their quality of life from a sleep intervention.

Does a Behavioral Parent Training Program for Parents of ADHD Children Improve Outcomes? A Pilot Project

Attention Deficit Hyperactivity Disorder (ADHD) is the most common chronic neurobehavioral disorder of childhood. Research suggests increased parent-child conflict exists in families with an ADHD child. The evidence indicates links between child behavior problems and parenting practices. Behavioral Parent Training (BPT) is an evidence-based intervention recommended for the treatment of ADHD. BPT is recommended as first-line treatment in ADHD children under age six and as a combination treatment approach for children older than the age six. BPT programs have demonstrated significant improvement in frequency of the problem behaviors of inattention, hyperactivity, and impulsivity associated with ADHD. Pre- and Post-BPT Parenting Scales and Vanderbilt ADHD Diagnostic Rating Scales for Parents and Teachers were used to evaluate the efficacy of the BPT program. Percent changes for each participant pre- and post-BPT were calculated. The Parenting Scale overall score and overreactivity factor score showed significant improvement post-BPT (p = .05). Participation in a BPT program can affect parenting practices and improve outcomes for ADHD children. BPT programs are effective in reducing negative parenting practices and improving outcomes for this population.

Parent and Family Processes Related to ADHD Management in Ethnically Diverse Youth

BACKGROUND

Previous research has shown major disparities in attention deficit hyperactivity disorder (ADHD) for diverse youth across America. We do not fully understand, however, how parent and family processes are related to the identification, care-seeking approaches, treatment preferences, and engagement with care systems and services for youth with ADHD.

OBJECTIVES

The present study aimed to explore parent and family processes related to the management of ADHD in racially and ethnically diverse youth.

DESIGN

This integrative review was structured with the methodology proposed by Whittemore and Knafl.

RESULTS

Three major electronic databases yielded a final sample of 32 articles (24 quantitative, 6 qualitative, and 2 mixed methods). Nine themes emerged within three overarching meta-themes.

CONCLUSIONS

Understanding the unique perspectives of families from diverse backgrounds is essential for clinicians, researchers, and policymakers, who are dedicated to understanding racial and ethnic perspectives and developing ecologically appropriate and family-based interventions for youth with ADHD.

Effects of hippotherapy on brain function, BDNF level, and physical fitness in children with ADHD

[Purpose]

The purpose of this study was to examine the effects of hippotherapy on brain function and levels of blood-derived neurotrophic factor (BDNF) in children with attention deficit and/or hyperactivity disorder (ADHD).

[Methods]

The hippotherapy group (HRG) included twenty children with ADHD and the control group (CG) included 19 children. All participants’ physical fitness, fMRI brain scans, and blood BDNF levels were measured at baseline and after 32 weeks of participating in hippotherapy.

[Results]

After 32 weeks of participating in hippotherapy, the body fat of the HRG was significantly decreased (-1.12 ± 4.20%) and the body fat of the CG was increased (2.38 ± 6.35%) (p=0.049). There was no significant difference of physical fitness in both groups (p>0.05). Although there was a higher decrease in the activated insular area in the HRG (-1.59 ± 0.99) than in the CG (-1.14 ± 1.41), there was no significant difference between the two groups (p>0.05) Also, there was a higher increase in the activated cerebellum area in the HRG (1.97 ± 1.45) than in the CG (1.92 ± 1.81). However, there was no significant difference between the two groups (p>0.05). BDNF levels showed an increased tendency in the HRG (166.29 ± 277.52pg) compared to the CG (21.13 ± 686.33pg); otherwise, there was not any significant difference in these blood levels between the two groups (p>0.05). It can be assumed that big individual differences in the level of ADHD in the study participants might not cause any significant results, although there might be positive changes in the brain function of children with ADHD.

[Conclusion]

Therefore, this study suggests that hippotherapy training would need to be modified and developed to increase the efficacy of hippotherapy in children with ADHD.

Association of ADHD symptoms and social competence with cognitive status in preschoolers

We aimed to investigate the association of attention-deficit hyperactivity disorder (ADHD) symptoms and social competence outcomes with cognitive status in preschool children. The study population was drawn from three birth cohorts belonging to the Spanish INMA (Infancia y Medio Ambiente) project: Menorca (n = 289), Ribera d'Ebre (n = 60), and Granada (n = 108). Children were assessed at the age of 4 years for cognitive functions (McCarthy Scales of Children's Abilities, MSCA) by psychologists and for inattention and hyperactivity symptoms (ADHD Criteria of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, ADHD-DSM-IV) and social competence (California Preschool Social Competence Scale) by their teachers. Multiple regression analyses were conducted to examine potential associations between behavioral outcomes (ADHD symptoms and social competence) and MSCA cognitive outcomes, adjusting for confounders. The presence of general ADHD symptoms (inattention, hyperactivity, or both) and poorer social competence both showed negative associations with cognitive outcomes. When we compared children according to ADHD subtypes, those with inattention symptoms alone and those with both inattention and hyperactivity symptoms showed significantly lower cognitive function scores in comparison to children with no ADHD symptoms. Behavioral dysfunctions in preschoolers may be associated with impairment of cognitive functions.

Artificial food dyes and attention deficit hyperactivity disorder

Attention deficit hyperactivity disorder (ADHD) is one of the most common behavioral disorders in children. Symptoms of ADHD include hyperactivity, low frustration tolerance, impulsivity, and inattention. While the biological pathways leading to ADHD are not clearly delineated, a number of genetic and environmental risk factors for the disorder are recognized. In the early 1970s, research conducted by Dr. Benjamin Feingold found that when hyperactive children were given a diet free of artificial food additives and dyes, symptoms of hyperactivity were reduced. While some clinical studies supported these findings, more rigorous empirical studies conducted over the next 20 years were less positive. As a result, research on the role of food additives in contributing to ADHD waned. In recent years, however, interest in this area has revived. In response to more recent research and public petitions, in December 2009 the British government requested that food manufacturers remove most artificial food dyes from their products. While these strictures could have positive effects on behavior, the removal of food dyes is not a panacea for ADHD, which is a multifaceted disorder with both biological and environmental underpinnings.

A 6-month, open-label, extension study of the tolerability and effectiveness of the methylphenidate transdermal system in adolescents diagnosed with attention-deficit/hyperactivity disorder

OBJECTIVE

The aim of this study was to evaluate the tolerability and effectiveness of the methylphenidate transdermal system (MTS) over 6 months in adolescents with attention-deficit/hyperactivity disorder (ADHD).

METHODS

This was an industry-sponsored, 30-center, open-label study of subjects aged 13-17 years with ADHD. Subjects were dose-optimized with MTS (10-30 mg/9 hours) over 5 weeks and then dose-maintained for up to 5 months. Tolerability evaluations included treatment-emergent adverse events (TEAEs) and dermal responses. Effectiveness was assessed with the ADHD-Rating Scale-IV (ADHD-RS-IV).

RESULTS

A total of 162 subjects received MTS treatment. The majority of TEAEs (>99%) were mild or moderate in intensity, and the most frequently reported TEAE was decreased appetite (15.4%). Thirteen subjects discontinued the study due to TEAEs. The majority (93.6%) of dermatologic reactions indicated mild erythema. There was significant improvement in mean ADHD-RS-IV total scores from study entry to end point (p<0.001).

CONCLUSION

Slightly more than half (54.0%) of subjects completed this 6-month, open-label extension study of MTS; the primary reason for discontinuation was withdrawn consent (36.0%). Reported TEAEs and skin tolerability findings were similar to those observed with MTS use in children and adolescents. MTS treatment resulted in a decrease in ADHD symptoms as rated by clinicians.
