Irritability, defined as proneness to anger that may impair an individual's functioning, is common in youths. There has been a recent upsurge in relevant research. The authors combine systematic and narrative review approaches to integrate the latest clinical and translational findings and provide suggestions for addressing research gaps.

Irritability as part of depression has been studied for a long time; it was a cardinal symptom in Burton's concept of melancholia and an underlying mechanism toward oneself in Freud's description of melancholia. Today, irritability is considered a cardinal symptom of depression in children and adolescents by DSM-5, along with depressed mood and anhedonia, and is present in about 40% of youth with depression. Longitudinally, irritability has been shown to be a specific predictor of depression across development in several studies.

Background: Adverse childhood experiences (ACEs) can have lasting effects on adult health and survival. In this study, we aimed to examine how the cumulative number and clustering patterns of ACEs were related to premature mortality.

Methods: Participants (=46 129; 45% White, 48% Black; 49·5% females) were offspring (born in 1959-1966) of participants enrolled in the Collaborative Perinatal Project (CPP).

Article Synopsis
  • The study examines differences between youth with Obsessive-Compulsive Disorder (OCD) and Autism Spectrum Disorder (ASD) compared to those with OCD alone, focusing on clinical features and treatment outcomes.
  • Young people with OCD and ASD were found to have poorer insight into their OCD, greater functional impairment, and higher levels of family accommodation.
  • Despite both groups benefiting from Cognitive Behaviour Therapy, those with OCD and ASD had significantly worse treatment outcomes, with medication and global functional impairment affecting the results.

Psychopathology is associated with impaired learning and early termination of schooling, whereas positive attributes are associated with better educational outcomes. However, it is important to understand if and how psychopathology and positive attributes longitudinally impact each other so we could shed light on where to intervene to promote educational outcomes through these constructs. A large prospective school-based community cohort of youths (5-15 years of age, 45% female) were assessed and followed up for 3 years (n = 2010; 80% retention).

Based on its course over time, irritability is linked to depression cross-sectionally and longitudinally. Cross-sectionally, irritability takes an episodic form as a symptom in pediatric depression; yet, irritability in the absence of depressed mood or anhedonia is rare. Longitudinally, chronic irritability has been shown to predict depression rather than bipolar disorder or externalizing disorders.

In child and adolescent psychiatry, irritability is listed as a cardinal or associated symptom in nearly every emotional, behavioral, and neurodevelopmental disorder in the DSM-5. Despite the omnipresence of irritability in distinct psychiatric disorders, its manifestation is highly heterogeneous, across and within individuals. Part of that heterogeneity has to do with its temporal dynamics.

Article Synopsis
  • Research shows a connection between depression and issues with processing rewards in both humans and animals, hinting at potential biomarkers and treatment targets.
  • The study critically examined existing findings and theories, using established causality frameworks and modern prediction techniques.
  • Through a preregistered meta-analysis, the researchers pointed out various challenges and determined that while reward processing issues aren't strong enough for clinical prediction, they might still contribute causally to depression.

Family accommodation (FA) refers to the participation of family members in obsessive-compulsive disorder (OCD) rituals. Most studies have focused on maternal accommodation; consequently, little is known about fathers' accommodation of OCD. The current study aims to extend the existing literature by examining maternal versus paternal accommodation of OCD symptoms.

To arrive at a coherent understanding of the relation between glucocorticoids and the human brain, we systematically reviewed the literature for studies examining the associations between endogenous or exogenous cortisol and human brain function. Higher levels of endogenous cortisol during psychological stress were related to increased activity in the middle temporal gyrus and perigenual anterior cingulate cortex (ACC), decreased activity in the ventromedial prefrontal cortex, and altered function (i.e.

Background: Aberrations in both neural reward processing and stress reactivity are associated with increased risk for mental illness; yet, how these two factors relate to each other remains unclear. Several studies suggest that stress exposure impacts reward function, thus increasing risk for psychopathology. However, the alternative hypothesis, in which reward dysfunction impacts stress reactivity, has been rarely examined.

Objective: Despite the clinical importance of chronic and severe irritability, there is a paucity of controlled trials for its pharmacological treatment. Here, we examine the effects of adding citalopram (CTP) to methylphenidate (MPH) in the treatment of chronic severe irritability in youth using a double-blind randomized placebo-controlled design.

Method: After a lead-in phase of open treatment with stimulant, 53 youth meeting criteria for severe mood dysregulation (SMD) were randomly assigned to receive CTP or placebo (PBO) for 8 weeks.

Background: Although severe irritability is a predictor of future depression according to recent meta-analytic evidence, other mechanisms for this developmental transition remain unclear. In this study, we test whether deficits in emotion recognition may partially explain this specific association in youth with severe irritability, defined as disruptive mood dysregulation disorder (DMDD).

Methods: Participants aged 8-20 years (M = 13.

Objective: A role for aberrant reward processing in the pathogenesis of depression has long been proposed. However, no review has yet examined its role in depression by integrating conceptual and quantitative findings across functional MRI (fMRI) and EEG methodologies. The authors quantified these effects, with an emphasis on development.

It has been suggested that the structure of psychiatric phenomena can be reduced to a few symptom dimensions. These proposals, mainly based on epidemiological samples, may not apply to clinical populations. We tested the structure of psychiatric symptoms across two pediatric clinical samples from England (N = 8434) and Norway (N = 5866).

Background: Irritability is one of the most common reasons for referral to child and adolescent mental health services and is the main characteristic of the new diagnosis of disruptive mood dysregulation disorder (DMDD). However, the recognition and management of irritability presents a major challenge in clinical practice and may be partly responsible for the dramatic increase in antipsychotic prescribing in recent years.

Methods: In this review, we provide up-to-date information on the definition and mechanisms underlying irritability, and its assessment in clinical practice.

Background: Vagal reactivity to stress in children has been associated with future psychiatric outcomes. However, results have been mixed possibly because these effects are in opposite direction in boys and girls. These sex differences are relevant in the context of development of psychopathology, whereby the rates of psychiatric disorders differ by sex.
