Objective: Attention-deficit/hyperactivity disorder (ADHD) is one of the most frequently occurring mental disorders in children and adolescents. The purpose of this study was to determine diagnostic persistence three years after the first clinical evaluation and to investigate the factors relating to diagnostic persistence in children and adolescents with ADHD., Methods: The study included 183 children and adolescents who were evaluated in the first admission. Of 183 children and adolescents, 142 children and adolescents were evaluated in the second admission and only the data of 142 children and adolescents were analysed in the study. Diagnostic persistence was defined as having met the full criteria for ADHD on second evaluation. Symptom severity of ADHD was determined using the Turgay DSM-IV-based Child and Adolescent Behavior Disorders Screening and Rating Scale-Parents Form (T-DSM-IV-S). Intelligence level was assessed through the Wechsler Intelligence Scale for Children-Revised., Results: Of the children included in the study, 77.5% (n = 110) were determined to have ADHD diagnostic persistence. Low intelligence levels, younger age and higher T-DSM-IV-S inattention and conduct disorder scores were associated with diagnostic persistence. ADHD diagnosis in children and adolescents tends to continue at high rates., Conclusions: Determination of the risks related to ADHD diagnostic persistence may contribute to improved treatment planning and interventions.

The aim of the present study was to investigate the factors associated with unintentional injury in children newly diagnosed with attention-deficit/hyperactivity disorder (ADHD). One thousand four hundred and thirty children between the ages of 6 and 18 who were diagnosed with ADHD for the first time in child psychiatry outpatient clinics were included in the present study. The socio-demographic information of the children, their developmental histories, chronic physical health conditions, comorbid psychiatric disorders, and information obtained via the Turgay DSM-IV-based Child and Adolescent Disorders Screening and Rating Scale were examined retrospectively. It was determined that 12.8% of the children (n D 183) experienced unintentional injury. It was established that age, male gender, disruptive behavioural problems, and low education levels among mothers were predictive of unintentional injuries. The results of the present study suggest that behavioural problems accompanying ADHD and comorbid psychiatric disorders are important in terms of unintentional injuries.

To investigate relationships between the polymorphisms and social functioning of children with Attention Deficit/Hyperactivity Disorder (ADHD), according to the polymorphism of three oxytocin receptor (OXTR) genes (rs53576, rs13316193, and and rs2268493). A total of 198 children-studying in the same primary and secondary school and matched in terms of age and gender (99 ADHD, 99 control)-were included in this study. The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version was administered to establish the clinical diagnosis. The Social Reciprocity Scale (SRS) was applied to evaluate social functioning. The total genomic DNA was isolated from buccal mucosa samples. No significant differences were determined between the ADHD and control groups in terms of rs2268493, rs13316193, and rs53576 genotype distribution (P = 0.078, P = 0.330, and P = 0.149, respectively). However, the control group T allele frequency in the OXTR Single Nucleotide Polymorphism (SNP) rs2268493 was significantly higher than the ADHD group (P = 0.024). Compared to the control group, the ADHD group had a higher score on the SRS scale (SRS total; Z = -21,135, P < 0.001). No significant difference existed in the SRS scale scores between the children with the T/T genotype and the C allele in the ADHD group (SRS total; Z = -0.543, P = 0.587). The allele distribution of the OXTR gene SNP rs2268493 was significantly different in the ADHD group, compared to the control group. This observation is important in understanding the underlying biological infrastructure in ADHD and developing treatment modalities., (© 2015 Wiley Periodicals, Inc.)

Objective: The aim of this study was to investigate medication persistence in Turkish children and adolescents with attention-deficit/hyperactivity disorder (ADHD). The effects of sociodemographic characteristics, symptom severity of ADHD, comorbidity, and treatment-related factors influencing medication persistence in children diagnosed with ADHD were studied., Methods: Medication persistence over a continuous 12 month period was evaluated for 877 children and adolescents between 6 and 18 years of age, who were diagnosed with ADHD for the first time and started to receive medication. Medication persistence was determined according to whether or not taking the prescribed medication continued for 12 months after the initiation of treatment. Whereas the symptom severity of ADHD was assessed by using the Turgay Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV)-based Child and Adolescent Behaviour Disorders Screening and Rating Scale-Parents Form (T-DSM-IV-S), perceived medication efficacy after the first treatment was evaluated by the Clinical Global Impressions-Improvement Scale (CGI-I)., Results: In this study, medication persistence over a continuous 12 month period occurred at a rate of 30.2% (n=265) in the subjects studied. The hierarchical regression analysis conducted in this research revealed that younger age, higher hyperactivity/impulsivity symptom severity, use of long-acting methylphenidate, addition of another ADHD medication, addition of other psychotropic medications, absence of side effects, and perceived medication efficacy were associated with successful medication persistence over a continuous 12 month period., Conclusions: Understanding the factors that affect medication persistence in ADHD may improve treatment efficacy and symptom control, while minimizing future risks.

Objective: Social interactions in children with attention deficit-hyperactivity disorder (ADHD) are inappropriate and such social problems may originate from a failure to attend to the appropriate cues of affect. The present study aimed to determine the factors predictive of social reciprocity in ADHD and their relationship to sociodemographics., Materials and Methods: Participants were required to interpret emotional cues depicted in pictures of facial expressions with a test that was adopted from the Reading Mind in the Eyes Test (RMET). Diagnoses were established based on the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL). Moreover, a detailed sociodemographic form, the Child Behavior Checklist (CBCL), and the Social Reciprocity Scale (SRS) were used for assessment., Results: This study included 133 children; 64 in the ADHD group and 69 in the control group. There wasn't a significant difference in mean age between the ADHD group (13.22 ± 1.28 years) and control group (12.97 ± 1.27 years). In all, 50% of the ADHD group and 49.3% of the control group were male. The mean RMET score was significantly lower in the ADHD group than in the control group (ADHD group: 20.52 ± 3.95; control group: 23.70 ± 3.55) and the mean SRS score was significantly higher in the ADHD group than in the control group (ADHD group: 65.84 ± 18.83; control group: 36.04 ± 16.32). In the ADHD group attention problems and lower level of ability to interpret emotional facial expressions were predictive of impaired social reciprocity., Conclusion: The findings show that both the ability to decode facial expressions and social reciprocity were impaired in the ADHD group. These findings highlight the difficulty children with ADHD have with social functioning and interpretation of emotions based on facial expressions.
