In a retrospective descriptive study of hyperkinetic conduct disorders (HCD) and conduct disorders (CD), as per ICD-10 diagnostic criteria, their clinical and phenomenological correlates were compared; with an aim of describing their distinctive clinical profiles. 20 cases of HCD and 25 cases of CD were compared on socio-demographic variables, temperament and specified clinical variables. The two groups differed in terms of the HCD group having younger age of onset, a more gradual development of and longer duration of conduct symptoms as compared to CD children. HCD children also had temperamental deviance (in the form of inattention, distractibility), lower IQ, more perinatal complications and delayed milestones as compared to the CD group; which made significant contribution to discriminant functions between the two groups. Results point towards different pathways of development of conduct symptomatology in HCD group as compared to the CD group.

Inconsistent findings exist regarding the association between maternal perinatal depression and the risk of Disruptive Behavioural Disorder (DBD) symptoms, including Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD) symptoms in children and adolescents. This study aimed to estimate the overall risk of DBD symptoms in offspring of mothers who have experienced perinatal depression. PubMed, Medline, Embase, Scopus, CINAHL, and Psych INFO were searched.

Background: This study was designed to evaluate content validity of the Dimensional Anhedonia Rating Scale (DARS), a patient-reported outcome measure, in adults with anhedonia in the context of major depressive disorder (MDD). To accomplish this, a conceptual model including the symptoms and impacts of anhedonia in the context of MDD was developed and refined through a targeted literature review, clinician interviews (N = 6), and participant interviews (N = 20).
Results: Using the final conceptual model, an item mapping exercise was conducted for the DARS, demonstrating that it provided suitable concept coverage in this population.
Latent Profiles of Impulsivity and Emotion Regulation in Children with Externalizing Disorders are Associated with Alterations in Striatocortical Connectivity.

Introduction: Children with externalizing disorders (EDs) often have difficulties with impulsivity and emotion regulation. These constructs have been associated with dysfunction in the recruitment of reward processing circuits and striatal connectivity with cortical networks. However, it is unclear to what extent co-presentations of impulsivity and emotion regulation are associated with differences in striatocortical connectivity.

Study Objectives: Rates of cannabis use disorder (CUD) appear to be increasing nationally, with increases greater in states that legalized cannabis use. However, as legalization has progressed and stigma declined, some of these apparent increases could be due to greater willingness of survey respondents and patients to acknowledge cannabis involvement. Biological indicators of cannabis use overcome some concerns about trends denoted by self-report data whose validity is potentially changing over time.

Background: Migraine is acknowledged as an intricate and incapacitating neurological malady, profoundly exerting a potent influence on the health-related quality of life of patients causing disability, and augmented burden on families, and entire communities. Notwithstanding the strides made in the field of headache disorder management, there remains a cohort of migraine-afflicted patients who do not encounter satisfactory alleviation. This emphasizes the need for alternative systems in addressing the issue and there is a growing interest in exploring Indian system of medicine to address migraine symptoms.
