Objective: The difficulties involved in social interaction among children with attention deficit hyperactivity disorder (ADHD) have been shown in many studies. Based on the knowledge that the imitation of facial expressions is a key factor in social interaction and functionality, the focus of prior studies has been on the evaluation of facial expressions in individuals with ADHD.

Objective: It is crucial to start early treatment in Spinal Muscular Atrophy (SMA) with available drugs to stop the progression of the disease, therefore making SMA screening preferable. This study assessed Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) compared to Multiplex Ligation-dependent Probe Amplification (MLPA) for detecting Spinal Muscular Atrophy (SMA) through SMN1 gene copy number analysis in a Turkish cohort.

Methods: We analyzed 249 DNA samples, previously tested for SMN1 and SMN2 gene deletion via MLPA, using qRT-PCR kits from three different companies.

Objective: We aimed to evaluate eye and head movements, which are objective parameters in ADHD. Method: While the children were watching the course video task, which included the relevant (teacher and smart board) and irrelevant (any regions outside the relevant area) areas of interest, their eye movements were evaluated through eye tracking, and video recordings were made simultaneous. Head position estimation was made using through video recordings.

Introduction: Expressing emotions through spontaneous facial expression is an important nonverbal social communication skill. In our study, we aimed to demonstrate that both children with autism spectrum disorder (ASD) and the non-ASD siblings of children with ASD have deficits in this skill.

Method: In this study, we analyzed the six core facial emotion expressions of three distinct groups of children - those diagnosed with ASD (n = 60), non-ASD siblings (n = 60), and typically developed children (n = 60).

Objective: The aim of the study was to evaluate sustained attention performance of children with ADHD and effect of distractors on sustained attention through an eye-tracking during a class-flow video task.

Method: Data were collected using an eye-tracking during a class-flow task conducted with 60 children (ADHD and control groups). Two areas of interest were determined in the task, these are relevant (teacher and whiteboard) and irrelevant (any regions outside the relevant area) areas.

Leaky gut hypothesis is one of the well-known theory which tries to explain etiology of Autism Spectrum Disorder (ASD). Unfortunately there is still a gap of evidence to investigate the corner points of the hypothesis. The aim of this study was to investigate the determinants of leaky gut in children with ASD, their siblings and healthy controls.

Objective: Cognitive developmental delay is a picture of the group of early-onset chronic diseases that affect 1.5-10% of children. Autism spectrum disorders are neurodevelopmental diseases with a genetic basis and abnormal brain development, characterized by disorders in areas that make up interpersonal relationships, such as communication, social cognition, and processing of emotional signals.

Objective: The current study aimed to investigate the psychopathology behind gynecomastia and potential associated problems regarding self-esteem and body perception, and the relationships of these variables with sex steroid levels in adolescents with pubertal gynecomastia.

Methods: The study included 50 normal weight male adolescents aged between 11 and 18 years with gynecomastia but without any chronic organic pathology, and 50 healthy pubertal male adolescents matched for age. The adolescents underwent psychopathology assessment by Development and Well-Being Assessment interviews; self-esteem was assessed using the Rosenberg Self-Esteem Scale; body perception was evaluated using the Body Image Perception Scale, and the relationship between these variables and sex steroid levels were explored.

Objective: Studies on etiopathogenesis of attention deficit/hyperactivity disorder (ADHD) are increasingly focussing on mitochondrial dysfunction. Children diagnosed with ADHD who had significantly higher mitochondrial DNA (mtDNA) copy numbers than healthy children in our first study were re-examined in 1-year follow-up to investigate effects of severity and treatment of ADHD on mtDNA.

Methods: Twenty-eight patients who participated in previous study were included in this follow-up study.

A remarkable number of children all over the world have psychiatric disorders, which cause severe impairments in functionality. In the development of future mental health planning, not only determining epidemiological data is sufficient, but also follow-up studies are needed. This study aimed to determine the course of subthreshold psychiatric disorders in three-year follow-up process, and whether there is a relationship between sociodemographic factors, parental attitudes and SDQ scores and the escalating escalation from SPD to psychopathology or the disappearance of SPD symptoms.

Recently, the number of epidemiological studies of child psychiatry has increased, but most of these studies focus on children living in city centres. Unfortunately, one-third of the global population lives in rural areas, and various habitations exist in cities, including city centres and slums. Moreover, despite having a high risk for psychopathology development, individuals who have symptoms but fall outside the limits specified for diagnoses due to having fewer symptoms than those mentioned in diagnostic systems and individuals who do not fulfil the impairment criteria listed in diagnostic systems are not addressed in these studies.
