Childhood and adolescent depression: a review of the past 10 years. Part II

A pilot study of adjunctive family psychoeducation in adolescent major depression: feasibility and treatment effect

OBJECTIVE

To obtain preliminary evidence of the feasibility and effectiveness of adjunctive family psychoeducation in adolescent major depressive disorder.

METHOD

Participants were from outpatient clinics in Hamilton and London, Ontario. Over 24 months, 41 adolescents ages 13 through 18 years meeting major depressive disorder criteria were recruited (31 in Hamilton, 10 in London). Participants were randomized to usual treatment or usual treatment plus family psychoeducation. Outcome measures were readministered at 2 weeks, mid-treatment, posttreatment, and 3-month follow-up. Intent-to-treat analyses used chi2 and t tests and growth curve analysis. Standardized effects based on growth curve estimates were calculated for continuous outcomes.

RESULTS

The London site was withdrawn because of poor participant retention. In Hamilton, no participant missed more than one assessment and there was good family psychoeducation adherence. Compared to controls, participants in the experimental group showed greater improvement in social functioning and adolescent-parent relationships (with medium standardized effect size > 0.5), and parents reported greater satisfaction with treatment.

CONCLUSIONS

There were positive treatment effects on family and social functioning processes postulated to mediate the clinical course of major depressive disorder. The study provides support for further evaluation of family psychoeducation in this clinical population.

Increased medial thalamic creatine-phosphocreatine found by proton magnetic resonance spectroscopy in children with obsessive-compulsive disorder versus major depression and healthy controls

Altered brain creatine-phosphocreatine levels might reflect changes in brain energy use and have been implicated in the pathogenesis of obsessive-compulsive disorder and major depressive disorder. We used proton magnetic resonance spectroscopy to measure absolute concentrations of creatine-phosphocreatine in the right and left medial thalami in 18 pediatric patients with major depressive disorder 9 to 17 years of age, 18 case-matched healthy controls, and 27 patients with obsessive-compulsive disorder 7 to 16 years old. The two patient groups were psychotropic drug naive and were not comorbid for the diagnosis of the comparison group. We found significantly increased left and right medial thalamic creatine-phosphocreatine concentrations in patients with obsessive-compulsive disorder compared with both healthy controls and patients with major depression. Creatine-phosphocreatine concentrations did not differ significantly between patients with major depression and healthy controls. Our data suggest that increased medial thalamic creatine-phosphocreatine concentrations in patients with untreated obsessive-compulsive disorder reflect altered energy use in the medial thalamus and might differentiate patients with obsessive-compulsive disorder from healthy controls and patients with major depression. Although these results must be considered preliminary, further study of the diagnostic specificity of creatine-phosphocreatine in obsessive-compulsive disorder is indicated.

Management options for bipolar disorder in children and adolescents

During recent years there has been a dramatic increase in the use of psychotropic medication for the treatment of bipolar disorder (BPD) in children. There is an emerging set of data to support this use.Mood stabilizers, including lithium and valproic acid (valproate sodium), have generally formed the mainstay of treatment in children and adolescents with BPD. However, the atypical antipsychotics, such as risperidone, aripiprazole, and quetiapine may be more effective as first-line treatment options and in some ways easier to use than the traditional mood stabilizers. As in adults, mood stabilization is often difficult to achieve in pediatric patients with BPD, and combined treatment with mood stabilizers and atypical antipscyhotics is commonly used. Data from controlled trials of psychotropic medications in children and adolescents with BPD are very limited, and hence, in the majority of cases physicians base their treatment decisions on data from case reports, case series, or open trials. More controlled studies of both monotherapy and polypharmacotherapy for BPD in children and adolescents are needed.

Adolescent depression: challenges and opportunities: a review and current recommendations for clinical practice

Many aspects of the treatment for adolescent depression are still uncertain. However, our body of knowledge continues to accumulate, and our approaches continue to be refined. When we remember that 40 years ago the field was still arguing about the existence of depression in youth, it is clear that significant progress has been made. Recent controversies have provided another opportunity to step back and re-evaluate. Given the chronicity, morbidity, and mortality associated with adolescent depression, the risks of doing nothing are too great. Evidence-based research has provided us with some direction during this unsettling time. After careful reviews, the major professional organizations representing pediatric medicine and psychiatry all support the continued use of SSRI antidepressant medications but emphasize close monitoring. The debates also have heightened interest in effective psychotherapy approaches, particularly CBT and IPT. Given the risk for suicidality in depressed adolescents, assessment and management of safety concerns remain critical, regardless of medication usage. Above all, it is most important that we remain hopeful about our ability to guide adolescents and families through the struggles with depression toward recovery.

Attachment and adolescent depression: The impact of early attachment experiences

Bowlby's (1969/1982) ideas of attachment as an interactional system provide the basis for an understanding of the development of adaptive and maladaptive working models of the self and other. More specifically, attachment theory can offer an in-depth understanding into the development of a depressotypic self-schema. Attachment theory is set alongside research into adolescent depression in order to illustrate the importance of the primary attachment relationship in protecting adolescents in our society from developing depressive symptomatology. Therefore, current research in adolescent depression is viewed through the lens of attachment theory. This view is complemented by an exploration of the role of culture in the production of gender differences in depression. Thus, a tripartite model of adolescent depression, including the individual, family relationships, and socio-cultural factors is offered as being of potential value for clinicians and researchers in this area.

[Selective serotonin reuptake inhibitors in major depressive disorder in children and adolescents (ratio of benefits/risks)]

Major depressive disorder in children and adolescents is associated with high risk of suicide and persistent functional impairment. While psychological treatments are used as a first line treatment in mild and moderately severe depression in this age group, the number of prescriptions for antidepressant medication (SSRI) has grown in recent years. Recently, FDA and MHRA advised that most of SSRI should not be used to treat MDD under the age of 18 years. They may increase the risk of suicidal thoughts and self harm. We reviewed the recent literature on efficacy and suicide risks of SSRI in depressed young people. Conflicting findings of SSRI efficacy have been reported in clinical studies. The discrepancies could be related to the heterogeneous samples and the absence of a standard definition of treatment effectiveness. In randomised placebo-controlled antidepressant clinical trials (RCT), the assessment of treatment effectiveness is commonly made with the CDRS-R (improvement of 20% or 30% or 40%) and CGI. SSRI demonstrated significantly, but modest, improvement compared with placebo in CGI score of 1 or 2: 10% more for sertraline, 16.8% more for paroxetine and between 16 to 24% more for fluoxetine. In adults, RCT studies have shown placebo response rates of 30% to 50%, drug response rates of 45% to 50% and drug-placebo differences of 18% to 25%. The highest placebo response rates, in young people, may be related to the highly selected group not representative of the general population of depressed patients and/or to the high youths' sensibility of psychotherapy. Patients participating in antidepressant clinical trials have a low BDI and CDI in Emslie's study for example (2002). In adults, previous reports suggest that SSRI use is associated with increased suicidal risk. But the analyse of 48 277 depressed patients participating in RCT for nine FDA approved antidepressants fail to support an overall difference in suicide risk between antidepressants (SSRI) and placebo treated subjects. An inverse relationship between regional change in use of antidepressants (increased) and suicide (decreased) is found in young -people in United States from 1990 and 2000. We can not draw a conclusion from few studies with few -participants. None suicide have been reported in pharmacological studies. And the link between "suicidality" and MDD can not be excluded. The instruments of assessment in depressed young patients are based on extensions of adult procedures. Whereas clinical picture of MDD in children, adolescents and adults have some differences. Depressed youngsters have more pronounced mood lability. Depressed adolescents have more anhedonia than depressed children. Future investigations into the efficacy and safety of treatments for children and adolescents depression should use specific instruments directly built on phenomenological and clinical picture of depressed children and adolescents. Comparison studies of pharmacotherapy, specific psychotherapies (not only CBT) and combined therapies are necessary to identify the adolescents who will benefit the most from specific or combined therapies. Further studies into the factors that influence treatment outcome including clinical picture (clinical dimensions, severity, duration, co morbidity), genetic factor, age, and i-llness course may help identify appropriate treatments for children and adolescents with MDD. Studies should include patients more severely ill, with associated psychiatric troubles, treatment resistance, history of relapses... In clinical studies, the link between "suicidality" and some clinical dimensions (which take part in clinical picture or not) must be analysed by assessing anhedonia, hopelessness feel, impulsive trait, borderline personality, familial inter-action, biological indices. New treatment should be expand and their efficacy and safety must be study: St John's worth, Bright light therapy, Trans-cranial Magnetic Stimulation.

IN PRACTICE

suicide and MDD have a strongest relation and it must be investigate syste-matically during the course of MDD. The suicide risk increases in the context of past history of suicide attempts, hopelessness, psychosis, impulsivity traits, substance abuse, familial dysfunction, life events, open access of arms. The use of SSRI in depressed children and adolescents is also the question of the quality and the support of the consultant and the mode of the prescription.

Neural regulation of bone and the skeletal effects of serotonin (5-hydroxytryptamine)

There is increasing evidence for a contribution of the neural system to the regulation of bone metabolism. The skeleton is richly innervated by both sympathetic and sensory neurons. While these nerves serve sensory and vascular functions, they are also being found to influence bone cell activities. The most convincing evidence for this has been provided by studies into the skeletal effects of the hormone leptin, which has been shown to centrally regulate bone mass, and through studies into the skeletal effects of hypothalamic neuropeptide Y2 and Y4 receptors. This paper discusses recent evidence for the neural regulation of bone metabolism and, in particular, the potential role of the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Recent studies have demonstrated the presence of functional pathways in bone for both responding to and regulating the uptake of 5-HT. This is of high clinical relevance given the role of the serotonergic system in affective disorders, and the wide use of pharmacological agents that target the 5-HT system to manage these disorders. Initial data suggest that exposure to these agents at different stages during the lifespan may have significant effects on the skeleton.

Which comes first in adolescence--sex and drugs or depression?

BACKGROUND

The notion that adolescents "self-medicate" depression with substance use and sexual behaviors is widespread, but the temporal ordering of depression and these risk behaviors is not clear. This study tests whether gender-specific patterns of substance use and sexual behavior precede and predict depression or vice versa.

METHODS

Data are from the National Longitudinal Study of Adolescent Health, weighted to produce population estimates. The sample includes 13,491 youth, grades 7 to 11, interviewed in 1995 and again 1 year later. Multivariate logistic regression analyses, conducted in 2004, tested temporal ordering, controlling for covariates. The main outcome measures were depression, as measured by a modified Center for Epidemiological Studies-Depression Scale (CES-D), and three behavior patterns: (1) abstaining from sexual intercourse and drug use, (2) experimental behavior patterns, and (3) high-risk behavior patterns.

RESULTS

Overall, sex and drug behavior predicted an increased likelihood of depression, but depression did not predict behavior. Among girls, both experimental and high-risk behavior patterns predicted depression. Among boys, only high-risk behavior patterns increased the odds of later depression. Depression did not predict behavior in boys, or experimental behavior in girls; but it decreased the odds of high-risk behavior among abstaining girls (RRR = 0.14) and increased the odds of high-risk behavior (RRR = 2.68) among girls already experimenting with substance use.

CONCLUSIONS

Engaging in sex and drug behaviors places adolescents, and especially girls, at risk for future depression. Future research is needed to better understand the mechanisms of the relationship between adolescent behavior and depression, and to determine whether interventions to prevent or stop risky behaviors will also reduce the risk of later depression.

Excessive sleepiness in adolescents and young adults: causes, consequences, and treatment strategies

Adolescents and young adults are often excessively sleepy. This excessive sleepiness can have a profound negative effect on school performance, cognitive function, and mood and has been associated with other serious consequences such as increased incidence of automobile crashes. In this article we review available scientific knowledge about normal sleep changes in adolescents (13-22 years of age), the factors associated with chronic insufficient sleep, the effect of insufficient sleep on a variety of systems and functions, and the primary sleep disorders or organic dysfunctions that, if untreated, can cause excessive daytime sleepiness in this population.

Inhibition of the serotonin (5-hydroxytryptamine) transporter reduces bone accrual during growth

Selective serotonin-reuptake inhibitors (SSRIs) antagonize the serotonin (5-hydroxytryptamine) transporter (5-HTT), and are frequently prescribed to children and adolescents to treat depression. However, recent findings of functional serotonergic pathways in bone cells and preliminary clinical evidence demonstrating detrimental effects of SSRIs on bone growth have raised questions regarding the effects of these drugs on the growing skeleton. The current work investigated the impact of 5-HTT inhibition on the skeleton in: 1) mice with a null mutation in the gene encoding for the 5-HTT; and 2) growing mice treated with a SSRI. In both models, 5-HTT inhibition had significant detrimental effects on bone mineral accrual. 5-HTT null mutant mice had a consistent skeletal phenotype of reduced mass, altered architecture, and inferior mechanical properties, whereas bone mineral accrual was impaired in growing mice treated with a SSRI. These phenotypes resulted from a reduction in bone formation without an increase in bone resorption and were not influenced by effects on skeletal mechanosensitivity or serum biochemistries. These findings indicate a role for the 5-HTT in the regulation of bone accrual in the growing skeleton and point to a need for further research into the prescription of SSRIs to children and adolescents.

Treating traumatized children: current status and future directions

Empirical knowledge regarding effective treatments for traumatized children has increased in the past decade, yet much still remains unknown. There is growing support for the efficacy of trauma-focused cognitive behavioral therapy (TF-CBT) for treating PTSD, depressive, and behavioral problems in sexually abused children, and evidence that suggests that this treatment is effective for children exposed to other types of trauma, and for multiply traumatized children. Few other psychosocial treatments have been adequately studied to date. Open psychopharmacological studies have identified several promising medication classes for traumatized children but these need to be tested in randomized, placebo controlled trials. No empirical studies have evaluated the efficacy of early interventions provided to children in the acute aftermath of mass disasters or terrorist acts. More research is needed to test potentially effective treatments for traumatized children, and to identify optimal methods for disseminating and implementing evidence-based treatments to community practitioners.

Neural systems of positive affect: relevance to understanding child and adolescent depression?

From an affective neuroscience perspective, the goal of achieving a deeper, more mechanistic understanding of the development of depression will require rigorous models that address the core underlying affective changes. Such an understanding will necessitate developing and testing hypotheses focusing on specific components of the complex neural systems involved in the regulation of emotion and motivation. In this paper, we illustrate these principles by describing one example of this type of approach: examining the role of disruptions in neural systems of positive affect in major depressive disorder in school-age children and adolescents. We begin by defining positive affect, proposing that positive affect can be distinguished from negative affect by its neurobehavioral features. We provide an overview of neural systems related to reward and positive affect, with a discussion of their potential involvement in depression. We describe a developmental psychopathology framework, addressing developmental issues that could play a role in the etiology and maintenance of early-onset depression. We review the literature on altered positive affect in depression, suggesting directions for future research. Finally, we discuss the treatment implications of this framework.

Reduced anterior cingulate glutamatergic concentrations in childhood OCD and major depression versus healthy controls

OBJECTIVE

To examine in vivo glutamatergic neurochemical alterations in the anterior cingulate cortex of pediatric patients with obsessive-compulsive disorder (OCD) without major depressive disorder (MDD) versus pediatric patients with MDD without OCD and healthy controls.

METHOD

Single-voxel proton magnetic resonance spectroscopic examinations of the anterior cingulate cortex were conducted in 14 psychotropic-naïve children and adolescents with MDD without OCD, 10 to 19 years of age, 14 case-matched healthy controls, and 20 nondepressed, psychotropic-naïve pediatric patients with OCD 7 to 19 years of age.

RESULTS

Anterior cingulate glutamatergic concentrations were significantly reduced in both patients with OCD (15.1% decrease) and patients with MDD (18.7% decrease) compared with controls. Anterior cingulate glutamatergic concentrations did not differ significantly between patients with OCD and those with MDD.

CONCLUSIONS

Altered anterior cingulate glutamatergic neurotransmission may be involved in the pathogenesis of OCD and MDD. These preliminary findings further suggest that reduced anterior cingulate glutamate does not differentiate pediatric patients with OCD from pediatric patients with MDD.

Cognitive-behavioral psychotherapy for anxiety and depressive disorders in children and adolescents: an evidence-based medicine review

OBJECTIVE

To review the literature on the cognitive-behavioral treatment of children and adolescents with anxiety and depressive disorders within the conceptual framework of evidence-based medicine.

METHOD

The psychiatric and psychological literature was systematically searched for controlled trials applying cognitive-behavioral treatment to pediatric anxiety and depressive disorders.

RESULTS

For both anxiety and depression, substantial evidence supports the efficacy of problem-specific cognitive-behavioral interventions. Comparisons with wait-list, inactive control, and active control conditions suggest medium to large effects for symptom reduction in primary outcome domains.

CONCLUSIONS

From an evidence-based perspective, cognitive-behavioral therapy is currently the treatment of choice for anxiety and depressive disorders in children and adolescents. Future research in this area will need to focus on comparing cognitive-behavioral psychotherapy with other treatments, component analyses, and the application of exportable protocol-driven treatments to divergent settings and patient populations.

Child mental health in Latin America: present and future epidemiologic research

OBJECTIVE

This report reviews population studies of child and adolescent mental health carried out in Latin America over the past 15 years. Also considered is the issue of how to meet the needs of children and adolescents who may present mental health problems in Latin America, given that most of them live in poverty in economies that are underdeveloped, providing limited resources.

METHOD

Ten studies from six different countries were identified that employed some form of randomized sampling method and used standardized instruments for assessment. The authors present a summary of the main characteristics of these studies, highlighting methodological features that may account for differences in the rates obtained.

RESULTS

Overall, a similar pattern of prevalence and risk factors for mental health problems in children and adolescents in Latin American countries emerged. Moreover, rates of disorders in these children are similar to the 15 to 20% found in other countries. These findings are similar to those observed when adult mental health problems are considered. Prevention and treatment strategies are discussed and the peculiarities of the delivery of mental health services for children and adolescents are explored.

CONCLUSIONS

Future research needs to focus on understanding of resilience and formal and informal mental health delivery systems of care available in different Latin American countries. Such research has high potential for ameliorating the prevention and treatment of child and adolescent mental health problems in this region of the world.

Depressive symptoms and adolescent eating and health behaviors: a multifaceted view in a population-based sample

BACKGROUND

Previous research has shown significant associations between depression and substance use and eating disordered behaviors. However, no research to date has described associations between depressive symptoms and nutritional intake or physical activity among adolescents in a nonclinical, population-based sample.

METHODS

Classroom surveys were completed by 4,734 ethnically diverse, middle- and high school students. Based on their depressive symptom scores, males and females were categorized with low-, moderate-, or high-depressive symptom status. Linear models were used to examine eating and health behavior variables by depressive symptom groups.

RESULTS

Depressive symptoms were positively associated with health-compromising attitudes such as perceived barriers to healthy eating and weight concerns, and health-compromising behaviors such as unhealthy weight-control behaviors and substance use, including caffeine. Depressive symptoms were negatively associated with health-promoting behaviors such as eating breakfast, lunch, and dinner. However, most associations between depressive symptoms and dietary micronutrients were not statistically significant. Health-promoting moderate-to-vigorous physical activity was negatively associated with depressive symptoms among males.

CONCLUSIONS

Adolescents who report depressive symptoms are at risk for other health-compromising attitudes and behaviors and are also less likely to engage in health-promoting behaviors. Depressive symptoms may be an underlying trait in the expression of health behaviors among adolescents.

Leitlinien zur Diagnostik und Psychotherapie von depressiven Störungen im Kindes- und Jugendalter: Ein evidenzbasierter Diskussionsvorschlag

Zusammenfassung. Ein Entwurf evidenzbasierter Leitlinien zur Diagnostik und Psychotherapie von depressiven Störungen im Kindes- und Jugendalter wird vorgestellt. Für die Diagnosestellung depressiver Störungen im Kindes- und Jugendalter müssen die gleichen diagnostischen Kriterien nach ICD-10 erfüllt sein wie für Erwachsene. Allerdings kann das klinische Bild einer Depression in verschiedenen Altersgruppen deutlich variieren. Depressive Störungen sind vor allem im Jugendalter häufig, chronische Verläufe und Rückfälle treten auf und sie gehen oft mit komorbiden Störungen wie Angststörungen, Störungen des Sozialverhaltens und Störungen durch Substanzgebrauch einher. Wirksame Interventionsansätze zur Prävention depressiver Störungen und zur Akutbehandlung bei leichten und mittelschweren depressiven Störungen stehen zur Verfügung. Die psychotherapeutischen Interventionen der Wahl stellen derzeit kognitiv-verhaltenstherapeutische Ansätze (KVT) und die interpersonale Therapie (IPT) dar. Die Antidepressiva der Wahl sind derzeit selektive Serotoninwiederaufnahmehemmer (SSRI). Weitere Studien, vor allem hinsichtlich Rückfallprophylaxe und der Evaluation der Wirksamkeit einer Kombinationsbehandlung von Psychotherapie mit antidepressiver Medikation stehen noch aus.

Escala de avaliação de depressão para crianças: um estudo de validação

A presente pesquisa teve por objetivo realizar um estudo de validação da "Escala de Avaliação de Depressão para Crianças" de Amaral e Barbosa (1990). Durante a realização da pesquisa a escala inicial foi modificada, obtendo-se quatro versões. Foi realizada análise semântica dos itens junto a duas amostras de crianças (N= 12 e N= 4). A seguir, quatro psicólogos clínicos e três psiquiatras analisaram a pertinência dos itens ao construto. E, finalmente, a escala foi aplicada à amostra de 362 estudantes, de escolas públicas e particulares, para o estudo da precisão e da validade de construto. Utilizou-se a análise fatorial exploratória; os índices de poder discriminativo dos itens, desvio-padrão e correlação corrigida item-total de Pearson; e o cálculo do Coeficiente Alfa (a), de Cronbach. Na compreensão semântica dos itens um item foi excluído e três foram reformulados. Não houve itens descartados na análise de juízes. Na análise fatorial exploratória observou-se que as quatro primeiras dimensões explicam 33,36% da variabilidade total dos dados, com autovalores acima de 1,4. Quatro itens foram descartados por apresentarem carga-fatorial menores do que 0,40. Na análise do poder discriminativo dos itens eliminaram-se seis itens com correlação item-total próximas de zero. A escala final ficou composta de 24 itens distribuídos segundo quatro fatores: resposta afeto-disfórico (a= 0,70); resposta afetivo-emocional com conteúdo de ansiedade (a= 0,65); resposta fisiológico-autonômica (a= 0,56); e resposta cognitiva com conteúdo de auto-estima (a= 0,50).

The characteristics of asymptomatic female adolescents at high risk for depression: the baseline assessment from a prospective 8-year study

OBJECTIVES

This longitudinal 8-year study assesses potential predictors of major depressive disorder (MDD) in a cohort of healthy adolescent females at high familial risk for MDD. The objective of this study was to ascertain whether risk factors for female onset MDD would differentiate youth at high or usual risk for MDD, prior to the onset of depressive symptomology.

METHODS

Subjects (ages 12-15 years) were assigned to a high (n=43) or usual (n=40) risk group according to maternal history of MDD. Depressive symptomatology (Beck Depression Inventory, Hamilton Rating Scale for Depression), pubertal development (Pubertal Developmental Staging Questionnaire), social support (Social Support Scale), and cognitive vulnerability (Depressive Experiences Questionnaire) were assessed.

RESULTS

High risk and usual risk group demonstrated no significant differences in demographic variables such as age, body mass index, and grade. Significantly more youth in the high risk group (n=40, 93%) had started menstruation, compared to youth in the usual risk group (n=31, 77.5%). There were no significant differences between the groups on measures of dysphoric cognitive style, perceived overall number of social supports, or satisfaction with social support.

CONCLUSIONS

Females at high familial risk for the onset of depression have significant differences in pubertal development, but not in demographics, depressive symptoms, social supports, or dysphoric cognitive style, when compared to females at usual risk for depression. These findings suggest that in prevention trials for depression in asymptomatic young women no non-biological risk factors for MDD aid in identifying females at higher risk for MDD.

Clinical presentation and course of depression in youth: does onset in childhood differ from onset in adolescence?

OBJECTIVE

To simultaneously and prospectively compare the clinical presentation, course, and parental psychiatric history between children and adolescents with major depressive disorder.

METHOD

A group of prepubertal children (n = 46) and postpubertal adolescents (n = 22) were assessed with structured interviews for psychopathology and parental psychiatric history and followed once every 2 years for approximately 5 years.

RESULTS

With the exception of more depressive melancholic symptoms in the adolescents, both groups had similar depressive symptomatology, duration (average 17 months), severity of the index episode, rates of recovery (85%) and recurrence (40%), comorbid disorders, and parental psychiatric history. Female sex, increased guilt, prior episodes of depression, and parental psychopathology were associated with worse longitudinal course.

CONCLUSIONS

In general, major depressive disorder is manifested similarly in children and adolescents, and both groups have a protracted clinical course and high family loading for psychiatric disorders.

Measuring mood and complex behavior in natural environments: use of ecological momentary assessment in pediatric affective disorders

This article describes the theoretical background and methodology of ecological momentary assessment (EMA) and reports results from a pilot study using EMA techniques in 16 children and adolescents with affective disorders and 5 subjects who were healthy and at low risk to develop future affective disorders. Multiple daily assessments of the subjects' mood, thoughts, and behaviors were performed in their natural environments using brief interviews on cellular phone calls by the study staff and by wrist actigraphy. The pilot results demonstrated that the EMA methodology is feasible in this population, as 17 of 21 subjects were able to complete the entire 8-week protocol. The potential usefulness of the EMA methodology is illustrated by specific case reports. Potential applications of the EMA methodology to the study of neurobehavioral systems and the pathophysiology of pediatric affective disorders are discussed.

Increased medial thalamic choline found in pediatric patients with obsessive-compulsive disorder versus major depression or healthy control subjects: a magnetic resonance spectroscopy study

BACKGROUND

Neurobiologic abnormalities in medial thalamus have been implicated in the pathogenesis of obsessive-compulsive disorder (OCD). We previously used multislice proton magnetic resonance spectroscopic imaging (1-H MRSI) to identify localized functional neurochemical marker alterations in choline (Cho) in medial but not lateral thalamus in treatment-naïve pediatric patients with OCD compared with matched control subjects. Altered brain Cho levels have also been implicated in the pathogenesis of mood disorders.

METHODS

We used 1-H MRSI to study absolute Cho concentrations in 18 psychotropic-naïve pediatric patients with major depressive disorder (MDD) not suffering from OCD, 9-17 years of age, 18 case-matched healthy control subjects, and 27 nondepressed, psychotropic-naïve pediatric patients with OCD, 7-16 years of age.

RESULTS

Significantly increased left and right medial thalamic Cho concentrations were observed in OCD patients compared with both healthy control subjects and patients with MDD. Medial thalamic Cho concentrations did not differ significantly between patients with MDD and control subjects.

CONCLUSIONS

These results suggest that localized functional neurochemical marker alterations in medial thalamic Cho differentiate patients with OCD from healthy control subjects and patients with MDD. Although these results must be considered preliminary, further study of the diagnostic specificity of Cho as a relevant biomarker in OCD is clearly warranted.

Depression and bipolar support alliance consensus statement on the unmet needs in diagnosis and treatment of mood disorders in children and adolescents

OBJECTIVE

To focus attention on the critical unmet needs of children and adolescents with mood disorders and to make recommendations for future research and allocation of healthcare resources.

METHOD

The 36-member Consensus Development Panel consisted of experts in child/adolescent or adult psychiatry and psychology, pediatrics, and mental health advocacy. Reviews of the literature concerning youth mood disorders were performed on the subjects of risk factors, prevention, diagnosis, treatment, and services delivery, and opinions and experiences of mental health advocates were obtained.

RESULTS

The Consensus Development Panel listened to presentations and participated in discussions. Independent workgroups of clinicians, scientists, and mental health advocates considered the evidence and prepared preliminary statements. Workgroup leaders presented drafts for discussion by the Consensus Development Panel. The final document was reviewed by the entire group and edited to incorporate input from all participants.

CONCLUSIONS

Evidence suggests high rates of unmet needs for children and adolescents with depression or bipolar disorder. Training is largely limited to child mental health specialists; general psychiatrists, pediatricians, and other primary care physicians receive little or no training. As a result, treatment patterns may reflect adult treatment plans that are not validated for youths. Effective treatments have been identified and some preliminary prevention models have been developed, but they are not yet widely applied. Patients experience limited exposure to clinicians adequately trained to address their problems and little information to guide care decisions, particularly concerning bipolar disorder. National efforts are required to restructure healthcare delivery and provider training and to immediately develop more advanced research on pathophysiology, prevention, and services delivery effectiveness.

Depression in children and adolescents

Depression is a common problem in children and adolescents. The disorder may be overlooked because of the prominent irritability seen in children with depression and because of the perception that moodiness is a normal phase of childhood. Depression frequently is associated with other psychiatric problems and neurologic disorders. Therapy consists of psychotherapy and medication, with SSRIs the first choice for pharmacotherapy.

Increased amygdala: hippocampal volume ratios associated with severity of anxiety in pediatric major depression

BACKGROUND

Neurobiologic abnormalities in the temporal lobe, particularly medial temporolimbic circuits, have been implicated in the pathogenesis of major depressive disorder (MDD). Although MDD commonly emerges during childhood and adolescence, to our knowledge, no prior study has examined temporal lobe anatomy in pediatric patients with MDD near the onset of illness before treatment.

METHODS

Volumetric magnetic resonance imaging scans were conducted in 23 psychotropic drug-naïve pediatric patients with MDD, aged 8-17 years, and 23 case-matched healthy comparison subjects.

RESULTS

Pediatric patients with MDD had significantly larger left (14%) and right (11%) amygdala:hippocampal volume ratios than controls. Increased left and right amygdala:hippocampal volume ratios were associated with increased severity of anxiety but not increased severity of depression or duration of illness.

CONCLUSION

These results suggest that alterations in amygdala:hippocampal volume ratios in pediatric MDD may more reflect severity of associated anxiety than depression. These results underscore the importance of assessment for comorbidity in the study of MDD.

Ethnic and sex differences in children's depressive symptoms: mediating effects of perceived and actual competence

Examined ethnic and sex differences in depressive symptoms, along with hypothesized mediators of those differences (academic achievement, peer acceptance), for a sample of African American (n = 272) and Euro-American (n = 630) children in Grades 3 to 5. Group comparisons revealed a significant Ethnicity x Sex interaction in depressive symptoms. African American boys reported more depressive symptoms than Euro-American boys, whereas African American and Euro-American girls reported comparable levels of depressive symptoms. Sex differences in depressive symptoms differed by ethnicity: Boys were more depressed than girls in the African American group whereas girls were more depressed than boys in the Euro-American group. The Ethnicity x Sex interaction was mediated by academic achievement, but not peer acceptance. These findings have implications for understanding the mechanisms underlying depressive symptoms in preadolescence and for developing interventions to prevent depression.

Maternal psychological distress: adult sons' and daughters' mental health and educational attainment

BACKGROUND

Offspring of depressed women have high rates of depressive symptoms and other psychopathology. The authors examined the relationship of mothers' symptoms of depression and anxiety reported during their offspring's childhood and adolescence on depressive disorder and educational achievement of their adult children.

METHOD

The data come from a longitudinal cohort study of first graders from Woodlawn, a neighborhood in Chicago, followed from age 6 to 32 years (N = 879). Adult children's depression and educational attainment are regressed on earlier self-reports of mothers' psychological distress. Using multiple logistic regression, the authors controlled for the relationships of poverty, mothers' education, mobility, family structure, mothers' illness, and children's first grade classroom behavior and psychological symptoms.

RESULTS

Daughters of mothers with persistent maternal psychological distress had two and a half times the risk of lifetime depressive disorder, but no increased risk of high school dropout. For sons, mothers' psychological distress was not related to depression but was related to poorer educational attainment.

CONCLUSIONS

Mothers' depressed feelings during the childrearing years relate to their children's depression and educational attainment as measured in adulthood. The patterns differ for sons and daughters.

Child and adolescent suicide: epidemiology, risk factors, and approaches to prevention

Suicide is rare in childhood and early adolescence, and becomes more frequent with increasing age. The latest mean worldwide annual rates of suicide per 100 000 were 0.5 for females and 0.9 for males among 5-14-year-olds, and 12.0 for females and 14.2 for males among 15-24-year-olds, respectively. In most countries, males outnumber females in youth suicide statistics. Although the rates vary between countries, suicide is one of the commonest causes of death among young people. Due to the growing risk for suicide with increasing age, adolescents are the main target of suicide prevention. Reportedly, less than half of young people who have committed suicide had received psychiatric care, and thus broad prevention strategies are needed in healthcare and social services. Primary care clinicians are key professionals in recognizing youth at risk for suicide. This article reviews recent population-based psychological autopsy studies of youth suicides and selected follow-up studies of clinical populations and suicide attempters, analyzing risk factors for youth suicides. As youth suicides are rare, research on risk factors for youth suicidal ideation and attempted suicide is also briefly reviewed. The relationship between psychiatric disorders and adolescent suicide is now well established. Mood disorders, substance abuse and prior suicide attempts are strongly related with youth suicides. Factors related to family adversity, social alienation and precipitating problems also contribute to the risk of suicide. The main target of effective prevention of youth suicide is to reduce suicide risk factors. Recognition and effective treatment of psychiatric disorders, e.g. depression, are essential in preventing child and adolescent suicides. Research on the treatment of diagnosed depressive disorders and of those with suicidal behavior is reviewed. In the treatment of youth depression, psychosocial treatments have proved to be useful and efficacious. Although studies on the effectiveness of selective serotonin reuptake inhibitors are limited in number, evidence supports their use as first-line antidepressant medication in youth depression. Available evidence suggests that various treatment modalities are useful in the treatment of suicidal youths, e.g. cognitive behavioral therapy and specialized emergency room interventions. Much of the decrease in suicide ideation and suicide attempts seems to be attributable to nonspecific elements in treatment. For high-risk youth, providing continuity of care is a challenge, since they are often noncompliant and commonly drop out or terminate their treatment prematurely. Developing efficacious treatments for suicidal children and adolescents would offer better possibilities to prevent suicides.

Medication treatment for depression in children and adolescents

Depression in children and adolescents is relatively common and associated with significant morbidity and mortality-thus, it is strongly deserving of treatment. To date, there have been a number of randomized, controlled trials of both tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs) in the acute treatment of depression in youths. Surprisingly, the available data do not demonstrate TCA superiority over placebo for this disorder in this age group. There is, however, evidence of SSRI superiority to placebo, and longer-term treatment with SSRIs may help prevent recurrence. There is almost no data on other pharmacologic approaches. Effective use of the efficacious treatments also depends on effective case-finding and providing treatment, which families and youths will take in adequate quantity and duration. The right approaches to these aspects of effective treatment are greatly understudied.

Depression in adolescence

Major depressive disorder is a common problem for adolescents. It has a wide array of symptoms affecting somatic, cognitive, affective, and social processes. Academic failure, poor peer relationships, behavioral problems, conflict with parents and other authority figures, and substance abuse are some of the consequences of major depressive disorder in this age group. Effective treatments include nontricyclic antidepressants and coping skills training. The nurse is key to depression detection and suicide prevention, especially in primary care settings. Through psychoeducation, nurses can promote recovery from depression by encouraging a healthy lifestyle, enhancing social skills, and assisting the adolescent to identify and use sources of social support. These measures can prevent premature death and promote long-term well-being of the adolescent.

The passage to adulthood: psychiatric rehabilitation service and transition-related needs of young adult women with emotional and psychiatric disorders

This review addresses the needs and experiences of young adult women, aged 16 to 21, who have a diagnosis of serious emotional disturbance (SED) or mental illness. Given the large numbers of young women with SED, evidence that they are underserved, and the continuity of many disorders from adolescence to adulthood, an integrative review in this area can enhance our ability to better address these young women's needs.

Child and adolescent depression: short-term treatment effectiveness and long-term opportunities

As with adult major depressive disorder (MDD), child and adolescent MDD is characterized as a common, chronic and recurrent disorder. It is also associated with short- and long-term functional impairment, morbidity, and mortality. Effective treatments, both psychotherapeutic and pharmacotherapeutic, are available for the short-term treatment and management of youth with MDD. However, to date, there are no data on the long-term treatment and management of children and adolescents with MDD and how long-term treatment may affect the outcomes of either high-risk or already affected youth. Understanding the long-term consequences of MDD during youth is as important as understanding how to treat a single episode of depression. Available data on the pharmacotherapeutic and psychotherapeutic options are discussed. In general, tricyclic antidepressants (TCAs) are not as effective for the treatment of youth with MDD as adults with MDD. The selective serotonin reuptake inhibitors (SSRIs) have been shown to be effective in children and adolescents with MDD and non-obsessive compulsive anxiety disorders. The serotonin and norepinephrine reuptake inhibitor (SNRI), venlafaxine XR, has been shown to be effective for the treatment of generalized anxiety disorder in children and adolescents. Understanding the long-term clinical consequences of depressive disorders in youth may provide opportunities for better intervention across the clinical course of illness. Early recognition, diagnosis and adequate treatment of 'high-risk' youth with subsyndromal depressive symptoms, treatment of acute episodes of depression to prevent 'kindling', and aggressive prophylaxis have the potential to improve the mental health of youth throughout their lives.

Psychological comorbidity and stress reactivity in children and adolescents with recurrent abdominal pain and anxiety disorders

OBJECTIVE

To compare clinical symptoms, diagnoses, and physiological measures in children and adolescents with recurrent abdominal pain (RAP) (n = 14), to a group with anxiety disorders (ANX) (n = 14) and a physically and psychiatrically healthy control group (HC) (n = 14).

METHOD

The cross-sectional study examined group differences in clinical symptoms of anxiety, somatic complaints, depression, and behavior problems. Physiological measures included heart rate, systolic and diastolic blood pressure, and salivary cortisol in response to the Trier Social Stress Test for Children (TSST-C). Subjects were between the ages of 8 and 16 years.

RESULTS

RAP and ANX subjects had comparable scores on most psychological measures, and their scores were higher (n < .05) than those of the HC. The ANX and RAP groups exhibited physiological findings that had more shared similarities than either group with the HC group. Few statistically significant group differences were noted in physiological measures, yet the pattern of findings in blood pressure and cortisol supported the use of the TSST-C and the direction of the findings was consistent with expectations.

CONCLUSIONS

Understanding more about comorbidity between RAP and anxiety could have important management implications, with observed congruities between the disorders suggesting treatments already demonstrated to be efficacious for pediatric anxiety and depression might be applied productively to RAP.

Depression in type 1 diabetes in children: natural history and correlates

The combination of diabetes and depression in children and adolescents is largely unstudied. The purpose of this article is to review the literature on the natural history and correlates of comorbid diabetes and depression in children and adolescents. Children with diabetes have a two-fold greater prevalence of depression, and adolescents up to three-fold greater, than youth without diabetes. Correlates of depression and diabetes include gender, poorer metabolic control, and family behaviors. Very little is known about treatment in these youth, and more studies are indicated.

Evaluation eines kognitiv-verhaltenstherapeutischen Gruppenprogramms für depressive Jugendliche und junge Erwachsene

Zusammenfassung. Im Rahmen der vorliegenden Studie wurde ein Gruppenprogramm in Anlehnung an den Adolescent Coping with Depression Course (CWD-A) der Arbeitsgruppe um Lewinsohn bei depressiven Jugendlichen und jungen Erwachsenen erprobt und auf seine Wirksamkeit hin überprüft. Das hochstrukturierte, psychoeduktive Gruppenprogramm wird in Kursen mit vier bis acht Teilnehmern über 10 zweistündige Sitzungen durchgeführt. Es werden vor allem soziale und kognitive Fertigkeiten, die Planung angenehmer Aktivitäten, Kommunikations- und Problemlösefertigkeiten sowie Entspannungsübungen fokussiert, deren Vermittlung über protokollierte Selbstbeobachtung, Rollenspiele und Verhaltensübungen realisiert wird. Bisher fanden vier Kurse mit insgesamt 24 Teilnehmern statt, die Depressionen in subklinischer oder klinisch relevanter Ausprägung bzw. komorbide depressive Störungen aufwiesen. Erste Analysen zeigen neben einer signifikanten Verringerung depressiver Symptomatik und irrationalen Denkens auch eine bedeutsame Zunahme erwünschter Verhaltens- und Erlebensweisen wie angenehmer Aktivitäten, Peerintegration, Optimismus und psychologischen Wohlbefindens. Zum Zeitpunkt des Kursendes waren 56 % der ursprünglich depressiven Teilnehmer remittiert.

Development and natural history of mood disorders

To expand and accelerate research on mood disorders, the National Institute of Mental Health (NIMH) developed a project to formulate a strategic research plan for mood disorder research. One of the areas selected for review concerns the development and natural history of these disorders. The NIMH convened a multidisciplinary Workgroup of scientists to review the field and the NIMH portfolio and to generate specific recommendations. To encourage a balanced and creative set of proposals, experts were included within and outside this area of research, as well as public stakeholders. The Workgroup identified the need for expanded knowledge of mood disorders in children and adolescents, noting important gaps in understanding the onset, course, and recurrence of early-onset unipolar and bipolar disorder. Recommendations included the need for a multidisciplinary research initiative on the pathogenesis of unipolar depression encompassing genetic and environmental risk and protective factors. Specifically, we encourage the NIMH to convene a panel of experts and advocates to review the findings concerning children at high risk for unipolar depression. Joint analyses of existing data sets should examine specific risk factors to refine models of pathogenesis in preparation for the next era of multidisciplinary research. Other priority areas include the need to assess the long-term impact of successful treatment of juvenile depression and known precursors of depression, in particular, childhood anxiety disorders. Expanded knowledge of pediatric-onset bipolar disorder was identified as a particularly pressing issue because of the severity of the disorder, the controversies surrounding its diagnosis and treatment, and the possibility that widespread use of psychotropic medications in vulnerable children may precipitate the condition. The Workgroup recommends that the NIMH establish a collaborative multisite multidisciplinary Network of Research Programs on Pediatric-Onset Bipolar Disorder to achieve a better understanding of its causes, course, treatment, and prevention. The NIMH should develop a capacity-building plan to ensure the availability of trained investigators in the child and adolescent field. Mood disorders are among the most prevalent, recurrent, and disabling of all illnesses. They are often disorders of early onset. Although the NIMH has made important strides in mood disorders research, more data, beginning with at-risk infants, children, and adolescents, are needed concerning the etiology and developmental course of these disorders. A diverse program of multidisciplinary research is recommended to reduce the burden on children and families affected with these conditions.

Depression in children and adolescents. When "moodiness" merits special attention

Depression does occur in children and adolescents and can result in significant morbidity and mortality. Therefore, identification and treatment of depression are essential. Referral to a mental health clinician, preferably a child and adolescent psychiatrist, is important for suicide evaluation, psychotherapy, and management of complicated medication treatment regimens. The SSRIs are most often used in youngsters because of their favorable side effect profiles and their efficacy as documented in some double-blind, placebo-controlled studies.

Smaller frontal lobe white matter volumes in depressed adolescents

BACKGROUND

Prior studies have demonstrated reduced frontal lobe volumes in depressed adolescents. In this study, frontal lobe gray and white matter volumes in adolescents with major depressive disorder were evaluated.

METHODS

Nineteen depressed and thirty-eight healthy comparison adolescents were recruited for a magnetic resonance imaging study. Images were segmented into gray matter, white matter, and cerebrospinal fluid. Morphometric measurements of the whole brain and frontal lobe region were completed.

RESULTS

Whole brain volumes were significantly smaller in depressed subjects compared with the healthy comparison subjects. Significantly smaller frontal white matter volumes and significantly larger frontal gray matter volumes were found in the depressed subjects, after controlling for age and whole brain volume.

CONCLUSIONS

These results are consistent with the hypothesis that a deficit in frontal volume exists during cortical development in adolescents with depression. Further studies are needed to assess whether volume differences resolve over time and the extent to which these differences influence response to treatment.

A prospective study of the role of depression in the development and persistence of adolescent obesity

BACKGROUND

Adolescent obesity is a strong predictor of adult obesity, and adult obesity has been associated with depression, especially in women. Studies have also suggested an association between depression in adolescence and higher body mass index (BMI) in adulthood. Whether depression leads to obesity or obesity causes depression is unclear.

OBJECTIVE

To determine in longitudinal analyses whether depressed mood predicts the development and persistence of obesity in adolescents.

METHODS

A prospective cohort study of 9374 adolescents in grades 7 through 12 who completed in-home interviews for the National Longitudinal Study of Adolescent Health. Assessments were made at baseline (1995) and at follow-up 1 year later. Depressed mood was assessed with the Center for Epidemiologic Studies Depression Scale. BMI (kg/m2) was calculated from self-reported height and weight. BMI percentiles and z scores were computed using the 2000 Centers for Disease Control and Prevention growth charts. Obesity was defined as BMI > or =95th percentile, overweight as BMI > or =85th percentile and <95th percentile, and normal weight as BMI <85th percentile. A parental respondent gave information on household income, parental education, and parental obesity.

RESULTS

At baseline, 12.9% were overweight, 9.7% were obese, and 8.8% had depressed mood. Baseline depression was not significantly correlated with baseline obesity. Among the 9.7% who were obese at follow-up, 79.6% were obese at baseline, 18.6% were overweight at baseline, and 1.8% were normal weight at baseline. Having depressed mood at baseline independently predicted obesity at follow-up (odds ratio: 2.05; 95% confidence interval: 1.18, 3.56) after controlling for BMI z score at baseline, age, race, gender, parental obesity, number of parents in the home, and family socioeconomic status. This finding persisted after controlling further for the adolescents' report of smoking, self-esteem, delinquent behavior (conduct disorder), and physical activity. After controlling for all these same factors, depressed mood at baseline also predicted obesity at follow-up among those not obese at baseline (odds ratio: 2.05; 95% confidence interval: 1.04, 4.06) and follow-up BMI z score among those obese at baseline (beta = 0.11; standard error beta = 0.05). In contrast, baseline obesity did not predict follow-up depression.

CONCLUSIONS

Depressed adolescents are at increased risk for the development and persistence of obesity during adolescence. Understanding the shared biological and social determinants linking depressed mood and obesity may inform the prevention and treatment of both disorders.

Recurrent pain, emotional distress, and health service use in childhood

OBJECTIVES

To determine the psychosocial correlates of recurrent pediatric pain and its relationship to health service use and medical presentations for "unexplained" symptoms in primary care.

STUDY DESIGN

Children 4 to 15 years of age who complained frequently of aches and pains to parents were compared with those with infrequent or no pain on measures of demographics, psychopathology, school attendance and performance, perceived health, and service use. Univariate analysis was followed by logistic regression.

RESULTS

Children who complained often of aches and pains used more health services, had more psychosocial problems, missed more school, and did worse academically. After controlling for health service use and demographics, recurrent pain was significantly associated with negative parental perceptions of child health and the presence of internalizing psychiatric symptoms. Higher levels of ambulatory health service use were associated with negative perceptions of child health, recurrent pain, visits for "unexplained" symptoms, and internalizing psychiatric symptoms.

CONCLUSIONS

Pediatric recurrent pain challenges traditional service delivery models characterized by segregated systems of care for physical and mental disorders. Longitudinal and psychobiological studies of the relationship between recurrent pain, internalizing psychopathology, and health beliefs are warranted to direct future treatment efforts.

Early Onset Dysthymic Disorder in Children and Adolescents: Clinical Implications and Future Directions

Early onset dysthymic disorder (EODD) is a serious psychiatric disorder that is associated with impaired social and relationship functioning, comorbid psychiatric conditions, a chronic course and increased risk for adult affective disorders. Unlike major depressive disorder (MDD) in childhood, which has been the focus of ongoing research, EODD has been relatively neglected in clinical practice and research. This paper reviews and evaluates EODD research findings and outlines pertinent clinical and research implications.

Health-related quality of life of children and adolescents with mental disorders

OBJECTIVE

To compare the health-related quality of life (HRQL) between children aged 6-17 years with one of three mental disorders (attention-deficit/hyperactivity disorder, major depressive disorder, or conduct disorder), a physical disorder, and those with none of these disorders.

METHOD

Parent reports describing the HRQL, mental disorders, and physical disorders of a national sample of 3,597 children and adolescents in Australia, aged 6-17 years (response rate = 70%), were obtained by means of a structured diagnostic interview and questionnaires.

RESULTS

After controlling for age, gender, and family structure, children with mental disorders were reported to have a significantly worse HRQL in several domains than children with no disorder. In many areas they were reported to have a worse HRQL than children with physical disorders. Parents also reported that the problems of children with mental disorders interfered significantly with the daily lives of children, parents, and families.

CONCLUSIONS

The findings are consistent with previous studies which have reported that adults with mental disorders have substantial impairment in their HRQL. The findings suggest that children with a mental disorder require help in many areas of their lives. Achieving this will require an integrated approach to health care delivery rather than the current distinction between physical and mental health services.
