The impact of ADHD on morality development

A Systematic Review on Social Cognition in ADHD: The Role of Language, Theory of Mind, and Executive Functions

Background: In this systematic review, conducted according to the PRISMA 2020 guidelines, we aimed to assess differences in the cognitive processes associated with social cognition-namely language, theory of mind (ToM), and executive functions (EFs)-between ADHD and control groups. Methods: The review included studies indexed in PubMed, Google Scholar, and PsycINFO up until May 2024. Eligible original peer-reviewed articles met the following criteria: they were written in English, included a clinical group with a current primary ADHD diagnosis, were empirical, included quantitative data, and utilized standardized and validated measures with adequate psychometric properties to assess social cognitive processes. Results and Discussion: A total of 1215 individuals with ADHD participated in the selected studies. Out of the 22 articles reviewed, 17 reported significant differences between ADHD and the controls across several cognitive processes related to language and EF rather than ToM. These processes included pragmatic skills, verbal and nonverbal communication, emotional prosody, interaction skills, sarcasm, paradoxical sarcasm recognition, ambiguous situations, emotion recognition, false belief, social problem solving, social behaviors, and gesture codification. We also discuss the limitations of the research and the implications of our findings. Systematic review registration: PROSPERO ID: CRD42023474681.

Attention-deficit/hyperactive disorder updates

Background

Attention-deficit/hyperactive disorder (ADHD) is a neurodevelopmental disorder that commonly occurs in children with a prevalence ranging from 3.4 to 7.2%. It profoundly affects academic achievement, well-being, and social interactions. As a result, this disorder is of high cost to both individuals and society. Despite the availability of knowledge regarding the mechanisms of ADHD, the pathogenesis is not clear, hence, the existence of many challenges especially in making correct early diagnosis and provision of accurate management.

Objectives

We aimed to review the pathogenic pathways of ADHD in children. The major focus was to provide an update on the reported etiologies in humans, animal models, modulators, therapies, mechanisms, epigenetic changes, and the interaction between genetic and environmental factors.

Methods

References for this review were identified through a systematic search in PubMed by using special keywords for all years until January 2022.

Results

Several genes have been reported to associate with ADHD: DRD1, DRD2, DRD4, DAT1, TPH2, HTR1A, HTR1B, SLC6A4, HTR2A, DBH, NET1, ADRA2A, ADRA2C, CHRNA4, CHRNA7, GAD1, GRM1, GRM5, GRM7, GRM8, TARBP1, ADGRL3, FGF1, MAOA, BDNF, SNAP25, STX1A, ATXN7, and SORCS2. Some of these genes have evidence both from human beings and animal models, while others have evidence in either humans or animal models only. Notably, most of these animal models are knockout and do not generate the genetic alteration of the patients. Besides, some of the gene polymorphisms reported differ according to the ethnic groups. The majority of the available animal models are related to the dopaminergic pathway. Epigenetic changes including SUMOylation, methylation, and acetylation have been reported in genes related to the dopaminergic pathway.

Conclusion

The dopaminergic pathway remains to be crucial in the pathogenesis of ADHD. It can be affected by environmental factors and other pathways. Nevertheless, it is still unclear how environmental factors relate to all neurotransmitter pathways; thus, more studies are needed. Although several genes have been related to ADHD, there are few animal model studies on the majority of the genes, and they do not generate the genetic alteration of the patients. More animal models and epigenetic studies are required.

Adopting the Concept of ‘Ba' and the ‘SECI' Model in Developing Person-Centered Practices in Child and Adolescent Mental Health Services

The concept of knowledge is divided into explicit and tacit knowledge; explicit knowledge refers to the knowledge that can be articulated, written and stored, while tacit knowledge refers to personal experiences, values, beliefs and emotions of an individual. By Nonaka's theory, explicit and tacit knowledge do not lie separately but interact together by interactions and relationships between human beings. Thus, the SECI model is based on the assumption that knowledge is created through the social interaction of tacit and explicit knowledge; known as knowledge conversion. The SECI model is based upon four modes of knowledge conversion; socialization, externalization, combination and internalization. 'Ba' is considered to be a shared platform for knowledge creation. 'Ba' is a shared space, be it physical, mental or a combination of both that serves as a foundation of knowledge creation. Ba involves sharing of tacit knowledge i.e. emotions, feelings, experiences and mental images. It also involves the formation of a collective relationship which is open to the sharing of practices, values, processes and culture. This concept focuses mainly on the individual as a person who holds the knowledge rather than just on the knowledge itself. It aims to create a common space to bring people together where they can dialogue to share and create knowledge. As in the relationships formed in person-centered practices, relationships formed in Ba are based on not just the sharing of objective knowledge but also on sharing values, beliefs, and emotions. It also reflects the formation of a person-centered environment as a basis for person-centered research where healthful relationships with the participants are formed. Furthermore, Ba will aid in creating a sense of connectiveness and dialogue, thus focusing on the idea that the development of new practices is done with others rather than to others. In this article we will discuss how these Eastern concepts can be adapted and used to develop person-centered practices within child and adolescent mental health services, specifically related to rehabilitation and recovery. The concepts of personhood will be discussed, followed by a reflection on current practices adopted when working with children and adolescents.

Investigative interviewing of youth with ADHD - recommendations for detective training

Attention deficit hyperactivity disorder (ADHD) in youth can lead to a trajectory of early and repeated contact with the criminal justice system (CJS), where such youth face significant challenges due to the nature of their diagnosis and the lack of specialized detective training in this area. This article reviews Australian detectives' perceptions regarding contact with ADHD-affected youth, ongoing contact of such youth with the CJS, and the impact of ADHD on interviewing time efficiency and quality of information gathered. It explores detectives' perceived impact of ADHD on components of the Cognitive Interview (CI). It overviews detectives' perceptions regarding their own skill/ability, training availability and future training preferences regarding the interviewing of ADHD-affected youth. The authors highlight best practice in specialized detective training, as well as in working with ADHD-affected youth. Recommendations are made regarding the design features of a potential specialized training programme for detectives interviewing ADHD-affected youth.

Assessing social cognition: age-related changes in moral reasoning in childhood and adolescence

OBJECTIVE

There is increasing recognition that socio-cognitive skills, such as moral reasoning (MR), are affected in a wide range of developmental and neuropsychological conditions. However, the lack of appropriate measures available to neuropsychologists poses a challenge for the direct assessment of these skills. This study sought to explore age-related changes in MR using an innovative visual tool and examine the developmental sensitivity of the task.

METHOD

To address some of the methodological limitations of traditional measures of MR, a novel, visual task, the Socio-Moral Reasoning Aptitude Level (So-Moral), was used to evaluate MR in 216 healthy participants aged 6-20 years.

RESULTS

The findings show a linear increase in MR from childhood to late adolescence with significant group differences between childhood (6-8 years) and preadolescence (9-11 years), and between early adolescence (12-14 years) and middle adolescence (15-17 years).

CONCLUSIONS

Interpreted in light of current brain development research, the results highlight age-related changes in MR that offer insight into typical MR development and opportunities for comparisons with clinical populations. The findings also provide evidence of the potential of the So-Moral as a developmentally appropriate measure of MR throughout childhood and adolescence.
