Childhood methylphenidate adherence as a predictor of antidepressants use during adolescence

Stimulant Treatment and Potential Adverse Outcomes in Pediatric Populations With Bipolar Disorder: A Systematic Review of the Literature

OBJECTIVE

To explore outcomes of stimulant treatment for ADHD in pediatric populations with particular attention to bipolar disorder (BPD).

METHOD

We conducted a literature search of PubMed articles published prior to August 25, 2022 that focused on BPD, mania, and psychosis prior to, or as result of, stimulant treatment. We excluded studies: (1) unrelated to stimulants, (2) general stimulant research, (3) articles older than 40 years, (4) study protocols, or (5) case reports.

RESULTS

A total of 11 articles met all inclusion/exclusion criteria. Some reports found stimulant treatment safe and well-tolerated in children with comorbid BPD and ADHD. Others found evidence of treatment-emergent mania (TEM), discontinuation, and other adverse events with stimulant treatment.

CONCLUSION

Poor outcomes associated with stimulant treatment in pediatric populations with BPD necessitate work to identify patients at risk of serious stimulant-related adverse events. Our results were limited by automated search filters and a pediatric, primarily male sample.

Association between Attention Deficit Hyperactivity Disorder Medication and Depression: A 10-year Follow-up Self-controlled Case Study

Objective

There is clinical concern that the stimulant methylphenidate (MPH) might increase the risk of depression, particularly in children. This study aimed to investigate the association between MPH use and the risk of depression.

Methods

A population-based electronic medical records database was used. We obtained claims data for prescription of ADHD medication, diagnosis of depression, and prescription of antidepressant medication between January 2007 and December 2016 for 43,259 individuals aged 6 to 19 who were diagnosed with ADHD between July 1, 2007 and December 31, 2007. The final analysis was based on 2,330 eligible participants. A self-controlled case series design was used to identify risk factors for major depressive disorder (MDD).

Results

An elevated MDD risk was found during the 90 days before MPH exposure, with an incidence rate ratio (IRR) of 12.12 (95% confidence interval [95% CI]: 10.06-14.61, p < 0.0001). During methylphenidate treatment, the IRR was 18.06 with a 95% CI of 16.67 to 19.56 (p < 0.0001), but it returned to baseline levels after day 31 of MPH treatment discontinuation. The IRR for patients aged 6 to 9 years was 13.11 (95% CI: 9.58-17.95) during the 90 days before MPH exposure, and 17.7 (95% CI: 15.6-20.08) during MPH treatment, but returned to baseline levels after discontinuation of MPH treatment.

Conclusion

We confirmed the temporal relationship between depression and methylphenidate use in young people with ADHD. Though the absolute risk is low, the risk of depression should be carefully considered, particularly in the period directly following the start of methylphenidate treatment.

Irritability and Inattention Not Sad Low Mood Predict Impulsiveness in Children and Adolescents With Major Depressive Disorder and Persistent Depressive Disorder

ABSTRACT

The specific relationships between impulsiveness, inattention, sad, low mood, and irritability have not been systematically examined in young people with major depressive disorder with and without persistent depressive disorder. The relationships are important to clarify because these symptom dimensions may increase suicidal risk in children and adolescents with these depressive disorders. A total of 313 medication-naive young people (aged 6-16 years) with active major depressive disorder (MDD) alone, persistent depressive disorder (DD) alone, and comorbid MDD and DD were identified. "Inattention," "sad/unhappy," and "irritable" mood were identified by parent standardized questionnaire. Standard multiple regression was used to investigate how well inattention, sad/unhappy, and irritable mood predict impulsiveness. Inattention (32% of the variance, increased) and irritable mood (5% of the variance, increased) both made independent significant contributions to impulsiveness, whereas sad/unhappy mood did not. Decreasing irritability via more targeted and comprehensive management approaches may ameliorate impulsiveness in young people with these depressive disorders.

Spatial working memory performance in children and adolescents with major depressive disorder and dysthymic disorder

BACKGROUND

Spatial working memory (SWM) is known to be impaired in children with Major depressive disorder (MDD), and, separately, Dysthymic disorder (DD) (DSM V persistent depressive disorder equivalent). Yet, it remains unclear whether MDD or DD is associated with worse SWM impairment, whether DD adds to the SWM impairments evident in MDD and whether these findings are evident in children as well as adolescents with MDD and DD.

METHODS

The association of SWM and its strategy and spatial span components is explored in carefully defined children and adolescents (age 6-16 years) with MDD alone (N = 29), MDD and DD (N = 130), DD alone (N = 154) compared to healthy typically developing participants (N = 107), controlling for age, gender, full scale IQ and social adversity status. The relationship between SWM and its strategy and span components and anxious/depressed and inattentive symptoms were also examined.

RESULTS

MDD was associated with worse SWM impairment than DD and there was no evidence of an additive effect of MDD and DD on SWM, strategy and spatial span deficits. Further, these findings were age-independent.

LIMITATIONS

The data presented are cross sectional and limited to SWM deficits in MDD and/or DD.

CONCLUSIONS

This study concurs with and extends current influential models about the cognitive effects of MDD and DD. Clinical implications and future research directions are discussed.

Contrasting effects of music on reading comprehension in preadolescents with and without ADHD

Children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are advised to study in quiet settings; yet, many professionals assert that environments devoid of external stimulus, are often unnecessary to facilitate optimal learning conditions. Empirical controlled trials examining this assertion are scarce. This study explored whether music improves reading performance of preadolescents with ADHD compared with typically developed (TD) peers, and its correlation with changes in heart rate variability (HRV), an autonomic nervous system indicator. After a pilot phase (N = 20; age = 12.05), additional independent sample of ADHD (n = 25; age = 10.28) and TD (n = 25; age = 10.44) preadolescents completed reading tasks under four conditions: without background music, with calm music without lyrics, calm music with lyrics, and rhythmic music with lyrics. Reading comprehension and mean-levels of HRV changes (before and during each task) were assessed using validated instruments. Reading comprehension significantly improved under the music conditions in ADHD group and deteriorated among TD. Differences in HRV changes were significant between groups, and explained reading performance. These findings suggest that music may improve attentive skills of preadolescents with ADHD, but not TD, and urge the need to identify an optimal fit between individual and contextual characteristics.

Discrepancies in adolescent-mother dyads' reports of core depression symptoms: Association with adolescents' help-seeking in school and their somatic complaints

OBJECTIVE

Parents of adolescents with mental problems do not always recognize the symptoms in their children, particularly regarding depression, and therefore do not seek professional help. Adolescents themselves tend to seek help from school personnel for their emotional or social difficulties. In contrast, adolescents do report somatic complaints and parents are likely to seek help for these problems. The current study explored whether the divergence between maternal and child reports of depression symptoms is associated with child's help-seeking in school and patterns of somatic complaints.

METHOD

A sample of 9th grade students (N = 693; 56% girls; mean age = 15.1) and their mothers representing the Muslim and Druze populations in northern Israel were interviewed simultaneously and independently. Maternal reports were classified either as underestimating, matching, or overestimating their own child self-report of three core symptoms of depression (depressed mood, anhedonia, and irritability). Adolescents reported whether they had consulted school staff and were classified into clusters based on self-reported somatic complaints.

RESULTS

Maternal misidentification of their child's depression symptoms was associated with increased help-seeking in school, particularly by boys if depressed mood or irritability were misidentified and particularly by girls if anhedonia was misidentified. Hierarchical cluster analysis indicated that the number and severity of somatic complaints was higher among adolescents whose depression symptoms were not identified, regardless of gender.

CONCLUSION

Mental health professionals, educators and parents should be aware that adolescents may attempt to communicate their emotional difficulties through somatic complaints and by seeking help in school.

Females with ADHD: An expert consensus statement taking a lifespan approach providing guidance for the identification and treatment of attention-deficit/ hyperactivity disorder in girls and women

BACKGROUND

There is evidence to suggest that the broad discrepancy in the ratio of males to females with diagnosed ADHD is due, at least in part, to lack of recognition and/or referral bias in females. Studies suggest that females with ADHD present with differences in their profile of symptoms, comorbidity and associated functioning compared with males. This consensus aims to provide a better understanding of females with ADHD in order to improve recognition and referral. Comprehensive assessment and appropriate treatment is hoped to enhance longer-term clinical outcomes and patient wellbeing for females with ADHD.

METHODS

The United Kingdom ADHD Partnership hosted a meeting of experts to discuss symptom presentation, triggers for referral, assessment, treatment and multi-agency liaison for females with ADHD across the lifespan.

RESULTS

A consensus was reached offering practical guidance to support medical and mental health practitioners working with females with ADHD. The potential challenges of working with this patient group were identified, as well as specific barriers that may hinder recognition. These included symptomatic differences, gender biases, comorbidities and the compensatory strategies that may mask or overshadow underlying symptoms of ADHD. Furthermore, we determined the broader needs of these patients and considered how multi-agency liaison may provide the support to meet them.

CONCLUSIONS

This practical approach based upon expert consensus will inform effective identification, treatment and support of girls and women with ADHD. It is important to move away from the prevalent perspective that ADHD is a behavioural disorder and attend to the more subtle and/or internalised presentation that is common in females. It is essential to adopt a lifespan model of care to support the complex transitions experienced by females that occur in parallel to change in clinical presentation and social circumstances. Treatment with pharmacological and psychological interventions is expected to have a positive impact leading to increased productivity, decreased resource utilization and most importantly, improved long-term outcomes for girls and women.

Refill Adherence Measures and Its Association with Economic, Clinical, and Humanistic Outcomes Among Pediatric Patients: A Systematic Review

Although refill adherence measures (RAMs) are widely reviewed on their use among adult patients, existing reviews on adherence among children have only focused on self-report measures and electronic monitoring. Hence, this systematic review aims to examine the use of RAMs and their association with economic, clinical, and humanistic outcomes (ECHO) among pediatric patients. A literature search was conducted in Pubmed, Embase, CINAHL, and PsycINFO. Studies published in English involving subjects aged ≤18 years were included if RAMs were analyzed with ECHO. Of the 35 included studies, the majority (n = 33) were conducted in high-income countries. Asthma was the most common condition (n = 9) studied. Overall, 60.6% of 33 clinical outcomes reported among 22 studies was positive (improved clinical outcomes with improved adherence), while 21.9% of 32 economic outcomes reported among 16 studies was positive (reduced healthcare utilization or cost outcomes with improved adherence). Only four studies evaluated the relationship of adherence with 11 humanistic outcomes, where the majority (72.7%) were considered unclear. RAMs are associated with ECHO and can be considered for use in the pediatric population. Future studies could explore the use of RAMs in low-income countries, and the association of RAMs with quality of life.
