Neurocognitive training enhances the outcomes of children with attention deficit hyperactivity disorder: A preliminary study

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder characterized by diverse clinical manifestations including inattention, hyperactivity and impulsivity.

OBJECTIVE

The present study aims to investigate the effects of neurocognitive training (NT), a personalized and specialized exercise programme on symptoms, attention and dynamic balance in treatment-naïve children diagnosed with ADHD.

METHODS

Fourteen treatment-naïve children aged 7-12 years diagnosed with ADHD were enrolled in the intervention group. The NT intervention was administered weekly for 10 consecutive weeks, supplemented by a structured home exercise programme for 6 days a week over the same 10-week period. ADHD-related symptoms, attention and dynamic balance were assessed in pre-treatment, post-treatment, 6 months, and 12 months. Fifteen typically developing (TD) children, matched for age, underwent evaluation only once to establish baseline normative values.

RESULTS

Following the NT (post-treatment), significant improvements were observed in hyperactivity-impulsivity scores, oppositional-defiant behaviours and dynamic balance when compared to the TD children (p < 0.05). In the ADHD group, a significant difference was found in the long term (12-month follow-up) in hyperactivity-impulsivity, oppositional-defiant behaviours and dynamic balance (p < 0.05).

CONCLUSION

The findings suggest that the NT yields favourable effects on hyperactivity-impulsivity, oppositional defiant behaviours and dynamic balance in children diagnosed with ADHD, with these improvements appearing to be sustained over the long term.

functional outcome in late adolescence/early adulthood of patients with autism spectrum disorder and its relationships with parental burnout and depression: A preliminary multi-center, cross-sectional study

The aim of this study is to determine the functioning of adults with autism spectrum disorders (ASDs) diagnosed in childhood and depression and burnout levels among their parents. A total of 261 adults with ASDs and their parents were recruited for the study. Both parents completed the Beck Depression and Maslach Burnout Inventories and reported the functioning of their adult offspring with ASDs. Only 5.4 % of our sample reported "good" or "very good" outcomes. The most common psychiatric comorbidities were intellectual disabilities and attention-deficit/hyperactivity disorder. Maternal burnout and depression scores were significantly elevated compared to those of fathers. There is an undeniable urgent need for more research to identify the needs of adults and families suffering from ASD. Modifications for those with ASD may have to be made for support in workplaces, achieving driving licenses, using public transportation and attendance at tertiary education.

Brain-derived neurotrophic factor in bipolar disorder: Associations with age at onset and illness duration

Bipolar disorder (BD) is a heterogeneous disorder that contains neurodevelopmental differences. Defining homogeneous subgroups of BD patients by using age at onset (AAO) as a specifier may promote the classification of biomarkers. This study compares peripheral BDNF levels between pediatric and adult BD patients to investigate the associations between BDNF levels, AAO, and illness duration. We enrolled two groups of euthymic patients, those with pediatric BD (n = 39) and those with adult BD (n = 31), as well as a group of healthy controls (HCs) (n = 90). Participants were assessed using clinical measures and BDNF serum levels were obtained using ELISA. We observed that BDNF levels were comparable between adult BD and HCs, but were clearly lower in pediatric BD than in HCs. In adult BD with AAO ≥30 years, BDNF levels were significantly higher than in adult BD with AAO <30 years. In pediatric BD, patients with prepubertal-onset had higher BDNF levels than those with pubertal-onset. BDNF levels demonstrated the accuracy of being able to distinguish pediatric BD from healthy controls in a receiver operating characteristic (ROC) curve analysis (area under the curve [AUC] = 0.792). In adult BD, higher BDNF levels were associated with later disease onset, but this was not the case in pediatric BD. Finally, reduced BDNF levels were associated with illness duration in adult BD. The findings indicate that BDNF levels in BD patients are associated with AAO. BDNF may, therefore, potentially serve as a developmental marker in BD, when AAO is taken into account.

Investigation of structure-function correlation among the young offspring of patients with bipolar disorder

Bipolar disorder (BD) has been associated with impaired executive functioning and integrity of fronto-limbic white matter tracts. The evaluation of these factors in young offspring of patients with BD (BDoff) as a high-risk group offers an opportunity to investigate factors that could predict vulnerability to the disorder. This study aims to examine the correlation between neurocognition and neuroimaging findings to evaluate the potential for these findings as biomarkers for the early recognition of BD. We enrolled BDoff (n = 16) who were aged between 12 and 18. Participants were assessed using clinical and neurocognitive tests. In addition, structural brain magnetic resonance and diffusion tensor imaging data were obtained. Mean fractional anisotropy (FA) and mean diffusivity (MD) values of the superior longitudinal fasciculus (SLF) and cingulum were extracted and correlations with neuropsychological data were analyzed. FA values in the SLF were negatively correlated with Stroop interference, the Wisconsin Card Sorting Test, and the Trail Making Test (B-A) scores. MD values in the cingulum were inversely correlated with the Child and Youth Resilience Measure and positively correlated with higher scores on the Barratt Impulsiveness Scale-Attentional. These findings provide a link between features of the brain and cognitive dysfunction in BDoff.

A retrospective study with ICAST-R (ispcan child abuse screening tools-retrospective) questionnaire for determination of child abuse in first year medical students in Turkish population

Child Abuse and Neglect (CAN) is an important problem both in Turkey and worldwide. Unfortunately, we still don't have enough and reliable data on this important subject. In this study, we aimed to investigate the prevalence of childhood maltreatment in a population of first year medical students in a Turkish university using the retrospective version of the ISPCAN Child Abuse Screening Tool (ICAST-R). One hundred seventy three first year medical students, aged between 18 and 24 years, who agreed to complete the ICAST-R questionnaire, were recruited in our study. Of 173 students who completed the survey, 51.4% are found to be subjected to at least one type of child abuse (physical, emotional or sexual). The prevalence is higher in male gender and the difference is statistically significant. Physical, emotional and sexual abuse exposure rates are found to be 23.1%, 40.5% and 11% respectively. Physical and emotional abuse rates are higher in male gender and the difference is statistically significant. We did not find any statistically significant association between gender and sexual abuse. Efforts to prevent child abuse and neglect are growing in our country, as they are worldwide. However, child abuse is still common and a problematic issue. It is important to determine the prevalence of child abuse in order to raise awareness. We need further studies investigating not only prevalence but also risk factors to have reliable data for our country.
