The Association of Non-obscene Socially Inappropriate Behavior With Attention-Deficit/Hyperactivity Disorder Symptoms, Conduct Problems, and Risky Decision Making in a Large Sample of Adolescents

This study used data from the Millennium Cohort Study to investigate the relationship between NOSI and emotional symptoms, conduct problems, and hyperactivity/inattention as assessed by the Strengths and Difficulties Questionnaire (SDQ) in 1,280 youths, aged 14 years. Furthermore, the relationship between NOSI and decision-making processes as assessed by the Cambridge Gambling Task (CGT) was investigated. Hyperactivity/inattention and conduct problems were significantly associated with NOSI; emotional problems were not. Risk taking was significantly associated with misbehaving in lessons but not with being rude or noisy in public. The results replicate and confirm the association of NOSI with ADHD and conduct problems in a large sample, although it should be stressed that the size of the association was small. The results also suggest that some inappropriate behaviors are related to risk-taking behavior, while others are not.

Conclusions: Neural development is an enormously complex and dynamic process. Immunological pathways are implicated in several early neurodevelopmental processes including the formation and refinement of neural circuits. Hyper-reactivity of systemic immune pathways and neuroinflammation may contribute to the natural fluctuations of the core behavioral features of CTD, OCD, and ADHD. There is still limited knowledge of the efficacy of direct and indirect (i.e., through environmental modifications) immune-modulatory interventions in the treatment of these disorders. Future research also needs to focus on the key molecular pa...

Authors: Iasevoli F, Barone A, Buonaguro EF, Vellucci L, de Bartolomeis A Abstract INTRODUCTION: Neurodevelopmental disorders (NDDs) are a group of complex and heterogeneous disorders, caused by the disruption of normal brain development. Antipsychotic agents are frequently used in these disorders to treat maladaptive conduct. However, a systematic evaluation of their safety/tolerability in NDDs is still lacking. Given the unique neurobiology of NDDs, antipsychotics may be expected to elicit distinctive side effects. AREAS COVERED: PubMed was systematically searched for all published studies from 1980 until 202...

Tic disorders (TD) are a group neuropsychiatric disorders with childhood onset characterized by tics, i.e. repetitive, sudden, and involuntary movements or vocalizations; and Tourette syndrome (TS) is the most severe form of TD. Their clinical manifestations are diverse; and are often associated with various psychopathological and/or behavioral comorbidities, including attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, depression, and sleep disorders. Individual severity and response to treatment are highly variable, and there are some refractory cases, which are less responsive ...

Movement, behavioral, and neuropsychiatric disorders in children have been linked to infections and a group of anti-neuronal autoantibodies, implying dopamine receptor-mediated encephalitis within the basal ganglia. The purpose of this study was to determine if anti-neuronal biomarkers, when used as a group, confirmed the acute disease in Sydenham chorea (SC) and pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS). IgG autoantibodies against four neuronal autoantigens (tubulin, lysoganglioside GM1, and dopamine receptors D1 and D2) were detected in SC sera (N=8), sera and/or cer...

The advent and application of high-throughput sequencing is revolutionizing our understanding of the molecular neurobiology of diverse psychiatric disorders. Whole-genome sequencing, which targets the coding regions of the genome, and whole-exome sequencing are being applied to study multiple psychiatric disorders, including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder, schizophrenia, and Tourette ’s disorder, among others [(1–3);]. These studies have demonstrated a role for ultrarare, deleterious, frequently de novo variation in each disorder, and h...

Tourette syndrome (TS), also known as Tourette ’s disorder, is a neurodevelopmental disorder with onset in early childhood characterized by multiple motor tics and at least one vocal tic that have been present for longer than 1 year. TS is a model neuropsychiatric disorder, in that the vast majority of affected individuals, whether ascertained in clinical or community settings, experience at least one co-occurring psychiatric disorder, such as attention-deficit/hyperactivity disorder, obsessive-compulsive disorder, and/or mood, anxiety, and specific learning disorders (1).

Conclusion: Clonidine has a limited evidence base for use in the management of behavioural problems in patients with ASD. Most evidence originates from case reports. Given the paucity of pharmacological options for addressing challenging behaviours in ASD patients, a clonidine trial may be an appropriate and cost-effective pharmaceutical option for this population.

Impulse control disorders (ICDs) are neuropsychiatric conditions characterized by the repeated inability to resist an impulse, drive, or temptation to perform an act that is harmful to the person or others. Although classification approaches to ICDs vary both diachronically and synchronically, this group of conditions encompasses a wide range of syndromes, including pathologic gambling, kleptomania, trichotillomania, excoriation (skin picking) disorder, intermittent explosive disorder, pyromania, oppositional defiant, conduct, and antisocial personality disorders. ICDs can play a significant role as comorbidities in both n...
