Purpose Of The Article: Cognitive training for Attention Deficit/Hyperactivity Disorder (ADHD) has shown promising, although mixed results. In post-hoc analyses, we evaluate effects of cognitive training using a novel composite cognition score as the outcome for children attending at least 16 sessions of training, dose-response of training and associations between symptoms and cognitive functioning.

Materials And Methods: Children (age 6-13) with ADHD were randomized to intervention ( = 26) or control ( = 34).

Background: Anxiety disorders are the most common childhood-onset psychiatric disorders and are extensively associated with child functional impairment. Data suggest that family accommodation plays a role in the association between anxiety severity and functional impairment in children, but more empirical evidence is needed.

Methods: Participants were 425 clinically anxious children (ages 6-17 years), and their mothers.

Article Synopsis
  • Environmental factors play a crucial role in developing obsessive-compulsive symptoms (OCS) alongside genetic influences, highlighting the need for further research on these factors.
  • A study of 1,877 children and adolescents explored various potential risk factors, measuring impacts over a 3-year period, with an average participant age of 10.2 years initially.
  • Key predictors for increased OCS at follow-up included lower socioeconomic status, lower IQ, younger age, higher maternal stress during pregnancy, lack of breastfeeding, parental baseline OCS, and youth's baseline anxiety and OCS scores.

Despite the knowledge that quality early childhood development programs, including those that target parental knowledge and behaviors, are essential for ameliorating the negative effects of early-life adversity, robust analyses of their implementation and impact in highly vulnerable settings are scarce. To address this knowledge gap, we conducted a pilot wait-list randomized controlled trial (RCT) to assess the impact and the process of implementing and evaluating the Mother-Child Education Program (MOCEP) among refugee families and one low-income community in Beirut, Lebanon. This paper focuses on the analysis of MOCEP's implementation (i.

Importance: Collective evidence has strongly suggested that deep brain stimulation (DBS) is a promising therapy for Tourette syndrome.

Objective: To assess the efficacy and safety of DBS in a multinational cohort of patients with Tourette syndrome.

Design, Setting, And Participants: The prospective International Deep Brain Stimulation Database and Registry included 185 patients with medically refractory Tourette syndrome who underwent DBS implantation from January 1, 2012, to December 31, 2016, at 31 institutions in 10 countries worldwide.

Tourette's syndrome is a neurodevelopmental disorder clinically characterized by multiple motor and phonic tics. It is likely that a neurobiological susceptibility to the disorder is established during development by the interaction of genetic, biochemical, immunological, and environmental factors. This study sought to investigate the possible correlation of several immunological and biochemical markers with Tourette's syndrome.
