Use of antidepressants for major depressive disorder in children and adolescents: clinical considerations.

Major depressive disorder (MDD) is a frequent condition among children and, especially, among adolescents. However, its clinical presentation usually differs from that of adults. It is also associated with other diagnoses and with an increased morbidity and mortality. However, MDD in this population remains underrecognized and undertreated. Antidepressants (ATDs) are chosen when psychoeducational, psychosocial and/or psychotherapeutic approaches have failed. ATDs are generally used in severe cases, and are always combined with psychological treatments. The objective of this work is to discuss the role of ATD in child and adolescent MDD. We focus on the recommendations of the most cited and updated clinical guidelines and discuss some controversial aspects with regards efficacy and safety issues that have been raised based on the information obtained from clinical trials. Finally, we offer some practical recommendations for clinicians. All these findings also pose some doubt on the hypothesis of MDD as a homogeneous phenomenon during the human life cycle.

Cognitive heterogeneity in the offspring of patients with schizophrenia or bipolar disorder: a cluster analysis across family risk.

BACKGROUND: Neurocognitive impairment is considered to lie on a continuum of severity across schizophrenia (SZ) and bipolar disorder (BP), possibly reflecting a gradient of neurodevelopmental load. Cluster analyses have identified different levels of impairment across the two disorders, from none to widespread and severe. We for the first time used this approach to examine cognitive function pooling together children and adolescents at familial risk of SZ or BP. METHODS: 220 participants, 49 offspring of individuals with schizophrenia (SZO), 90 offspring of individuals with bipolar disorder (BPO) and 81 offspring of healthy control parents (HC), aged 6 to 17 years, underwent a comprehensive clinical and cognitive assessment. Cognitive measures were used to group SZO and BPO using K-means clustering. Cognitive performance within each of the clusters was compared to that of HC and clinical variables were compared between clusters. RESULTS: We identified three cognitive subgroups: a moderate impairment group, a mild impairment group, and a cognitively intact group. Both SZO and BPO were represented in each of the clusters, yet not evenly, with a larger proportion of the SZO in the moderately impaired cluster, but also a subgroup of BPO showing moderate cognitive dysfunction. LIMITATIONS: Participants have yet to reach the age of onset for the examined disorders. CONCLUSIONS: The findings point to a range of neurodevelopmental loadings across youth at familial risk of both SZ and BP. They have therefore important implications for the stratification of cognitive functioning and the possibility to tailor interventions to individual levels of impairment.

[Patient care, right to information and consent for minors in situations of parental conflict. Clinical guidelines in the context of Spanish legislation]. / Atención a menores con progenitores en conflicto en materia de información y consentimiento relativos a la salud de los hijos. Protocolo asistencial en el contexto de la legislación vigente.

Among the main social and legislative changes as regards family matters that have taken place in Spain in the last few years, are included: (i) the gradual increase in legal disputes between parents, and (ii) the introduction of Law 26/2015 on Child Protection, which modified Law 41/2002 on the Freedom of the Patient. These searched for a balance between the rights of minors and the powers of the parents, particularly when the former had not reached 16 years or had sufficient maturity or, having reached it, the decision puts their life or health at severe risk. Likewise, it has led to a jurisprudence that determines that, for any minor, there are particularly sensitive, "special" or "important" health care actions, such as psychotherapy or surgical treatments, which require, with exceptions, the consent of both parents for it to be carried out. All this, however, subject to the discretion of the doctor responsible, who must always look after the best interests of the minor. For this reason, healthcare for minors, occasionally, lead to complex conflicts as regards information and consent by the parents, particularly when they do not agree. A review is presented on the current legislative framework and the main legal concepts that regulate the healthcare of minors as regards information and consent relative to health, as well a healthcare protocol for the care of minors in situations of conflict between parents, developed in the Gregorio Marañón Hospital of Madrid, and endorsed by the Official Medical Collegiate of Madrid.

The role of serotonin in adolescent suicide: theoretical, methodological, and clinical concerns.

INTRODUCTION: Adolescent suicide is a complex phenomenon that has similarities and differences with adult suicidal behavior. Serotonergic (5-HT) dysfunction has extensively been studied in adults and has been postulated as a biological marker for suicide. METHODS: We conducted a comprehensive review of the studies available in MEDLINE from January 1998 until January 2014 on the role of "serotonin" both in adults' and adolescents' "completed suicide", "suicide attempts", and "suicidal ideation". RESULTS: Studies on 5-HT conducted in adults and replicated in adolescents have yielded inconsistent results. Although some genes related to the serotonergic system have been associated with an increased risk of suicide, attempts to reproduce those findings have been unsuccessful and a common genetic variant associated to suicidal behavior has yet to be identified. DISCUSSION: Studies on the neurobiology of adolescent suicide should consider the biological specificities of this life stage and of gender differences during this period. Future research designs should also try to integrate findings in the psychological and biological domains. Prospective studies may help understand the process that leads from suicidal ideation to suicide attempts or completed suicides in this population.

Hypothalamic-pituitary-adrenal axis dysfunction as a neurobiological correlate of emotion dysregulation in adolescent suicide.

BACKGROUND: Biological markers of vulnerability for current or future risk of suicide in adolescents could be important adjuncts to the treatment and prevention of this phenomenon. DATA SOURCES: We conducted a PubMed search of all English-language articles published between January 1990 and June 2011 using the following search terms: ("hypothalamic-pituitary-adrenal" OR "HPA") AND ("adolescence" OR "adolescent" OR "teenager") AND ("depression" OR "major depressive disorder" OR "suicidal behavior" OR "suicidal ideation" OR "suicidal thoughts" OR "deliberate self-harm" OR "suicidal attempt" OR "suicide"). RESULTS: HPA axis activity can be examined using different methods that do not have the same biological interpretation. An abnormal HPA axis functioning together with an anomalous interaction between HPA mechanisms and other systems such as the serotonergic system may be one of the neurobiological correlates of emotion dysregulation (ED). ED may play an important role in adolescent suicidal behavior. Some psychopathological conditions such as depression or childhood psychological trauma that increase suicidal risk in adolescents are also associated with HPA axis dysregulation. ED, a personality trait, can also be viewed as a predisposing factor that augments the vulnerability to suffer from psychiatric conditions. CONCLUSIONS: Correlating HPA axis dysfunction with psychological factors such as ED could lead to a better understanding of the role of HPA abnormalities in adolescent suicide and may enhance preventive and treatment strategies.
