Stratification by age at onset has been useful for genetic studies across all of medicine. For the past 20 years, the National Institute of Mental Health has been systematically recruiting patients with onset of schizophrenia before age 13 years. Examination of familial transmission of known candidate risk genes was carried out, and a 10% rate of cytogenetic abnormalities was found. Most recently, high-density, array-based scans for submicroscopic rare copy number variations (CNVs) have suggested that this kind of genetic variation occurs more frequently than expected by chance in childhoodonset schizophrenia (COS) and at a higher rate than observed in adult-onset disorder. Several CNVs and cytogenetic abnormalities associated with COS are also seen in autism and mental retardation. Populations with COS may have more salient genetic influence than adult-onset cases. The relationship of rare CNVs to prepsychotic development is being studied further.

Clinician burnout has significant socioeconomic, health, and quality of life implications. However, there has been little attention directed at medical students and house officers (i.e., medical learners). This review provides pertinent evidence regarding burnout as it relates to medical learners including risk factors and potential interventions. We conclude with recommendations on future research directions and potential approaches to address this epidemic of medical learner burnout. Burnout is a significant issue among medical learners that is impacted both by interpersonal and environmental factors. There are points of heightened vulnerability for medical learners throughout their training. However, studies are unable to reach consensus regarding effective interventions to mitigate the impact of burnout. Furthermore, some elements of burnout are not readily reversible even after removing risk factors. Burnout is a significant concern for medical learners with wide-ranging physical, emotional, and psychosocial consequences. However, the current body of literature is sparse and does not provide consistent guidance on how to address burnout in medical learners. It is clear additional attention is needed in understanding burnout among learners and establishing proactive approaches to minimize its negative impact.

Ethical issues in the field of schizophrenia research have become a focus of intense debate in the past year. The publication of the final report of the National Bioethics Advisory Commission (NBAC) coupled with recent media reports have catapulted these issues into international view. Major questions have been raised about the capacity of individuals with mental illness to consent to participation in research studies and about the conflicts of interest that psychiatric researchers experience. Questions have also been raised about whether it is ethical to ask patients with schizophrenia to participate in studies that can be expected to lead to an increase in psychotic symptoms.

Emotional lability, or sudden strong shifts in emotion, commonly occurs in youth with attention-deficit/hyperactivity disorder. Although these symptoms are impairing and disruptive, relatively little research has addressed their treatment, likely due to the difficulty of reliable and valid assessment. Promising signals for symptom improvement have come from recent studies using stimulants in adults, children and adolescents. Similarly, neuroimaging studies have begun to identify neurobiological mechanisms underlying stimulants’ impact on emotion regulation capacities. Here, we review these recent clinical and neuroimaging findings, as well as neurocognitive models for emotional lability in ADHD, issues of relevance to prescribers and the important role of psychiatric comorbidity with treatment choices.

This article critically reviews research done in the past 2 years concerning the pathophysiology and treatment of autism. Recent research in genetics, neuroimaging, neurochemistry, and pharmacologic treatment has advanced the body of knowledge about the pathophysiology of autism. Relatively new imaging technologies (eg, positron emission tomography) are increasingly being applied to the study of subjects with autism and have produced promising results that await replication. Neurochemical and challenge studies continue to suggest a role for 5-HT dysregulation in autism. Additional research is needed to determine the role of neuroendocrine and autoimmune factors in autism. Significant gains have been made in determining which pharmacologic treatments are efficacious in autism. Additional research is needed on agents that might ameliorate the core and associated symptoms of autism.

Specific treatments targeting adolescents with substance use disorders (SUDs) have been developed over the last couple of decades. Despite these developmentally tailored treatments, long-term abstinence rates remain relatively low among adolescents receiving care. Research over the last decade has increasingly focused on adolescents with comorbid substance use and psychiatric disorders, in recognition of the barriers caused by inadequate treatment of co-occurring psychiatric disorders. Treatments targeting dually diagnosed youth are now regarded as essential to improving SUD treatment outcomes, but remain underutilized. A variety of treatment modalities such as behavioral therapy, family therapy, 12-step groups, motivational interviewing, contingency management, and combinations of these interventions have been modified for adolescents. In this article, we review the research on these treatments, as they apply to dually diagnosed youth. Furthermore, we explore the evidence for various treatments targeting comorbid SUD, specific to the presence of externalizing or internalizing disorders. The current evidence base supports the importance of integrated treatment targeting both SUD and psychiatric disorders simultaneously. High-quality treatment programs offering combinations of behavioral and family therapy, particularly with motivational interviewing and contingency management, are particularly well supported. In addition, we review various psychotropic medication treatments that have also been studied in conjunction with adolescent SUD treatment. Finally, we review research on post-treatment, supportive care that has been shown to improve long-term SUD outcomes. Recently conceptualized modular treatments, which offer personalized combinations of evidence-based treatments for specific disorders, have been proposed as a means of improving outcomes. Future research on modular programs must test the efficacy of individualized treatments when applied to combinations of psychiatric and SUDs in adolescents.
