A review of executive function deficits in autism spectrum disorder and attention-deficit/hyperactivity disorder

Executive dysfunction has been shown to be a promising endophenotype in neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). This article reviewed 26 studies that examined executive function comparing ASD and/or ADHD children. In light of findings from this review, the ASD + ADHD group appears to share impairment in both flexibility and planning with the ASD group, while it shares the response inhibition deficit with the ADHD group. Conversely, deficit in attention, working memory, preparatory processes, fluency, and concept formation does not appear to be distinctive in discriminating from ASD, ADHD, or ASD + ADHD group. On the basis of neurocognitive endophenotype, the common co-occurrence of executive function deficits seems to reflect an additive comorbidity, rather than a separate condition with distinct impairments.

Parents Psychopathology of Children with Attention Deficit Hyperactivity Disorder.

Attention Deficit Hyperactivity Disorder (ADHD) is a disorder with extremely complex etiology, not yet well defined but certainly multi-factorial. This study investigated the possible etiopathogenetic role of ADHD symptoms and psychopathology disorders in parents of children with ADHD. We present a case-control study of parents of 50 children affected by ADHD and of 45 healthy children, matched to age and gender. Parents of ADHD children reported higher levels of ADHD symptoms, depressive disorders and Depressive Personality Disorders than parents of healthy children. Mothers displayed greater presence of depression, while fathers showed problems concerning alcohol use. The occurrence of ADHD symptoms, psychopathology and personality disorders in parents highlights the importance to integrate the treatment programs in the ADHD children with the screening and treatment for psychopathological symptoms of the parents.

Autism spectrum disorders in XYY syndrome: two new cases and systematic review of the literature

Abnormalities of the sex chromosomes (47, XXY, 47 XYY, 45,X/46,XY mosaicism) are frequently associated with Autism Spectrum Disorders (ASD), but the male predisposition to these disorders has not been clearly explained. Previously, the role of the X chromosome was considered important in the ASD mainly because autistic symptoms were detected in genetic syndromes involving X chromosome (fragile X syndrome, Rett syndrome, Klinefelter syndrome). Instead, few studies have analyzed the possible role of the Y chromosome in the ASD. This study explores the role of the Y chromosome in ASD through a systematic literature review about the association between ASD and XYY syndrome and a description of two new cases with this association. The literature review considered studies published in peer-reviewed journals, included in the MEDLINE and PubMed databases, that examined the association between ASD and XYY syndrome. Few studies reported the occurrence of ASD in children with XYY karyotype and the majority of them did not reported a well-defined autism diagnostic category associated with an extra Y chromosome, but several clinical conditions that are generically described as language and social impairment. Conclusion: This study underlines the underestimated role of the Y chromosome in ASD, and we postulate that all the ASD associated with the XYY karyotype may presumably fall within mild degree of ASD as in our cases.

Tolerability and safety profile of risperidone in a sample of children and adolescents.

The aim of this prospective observational study was to verify the tolerability and safety profile of risperidone in a sample of antipsychotic-naive children/adolescent patients having a different psychiatric diagnosis. Twenty-two (mean age of 12±3.2) antipsychotic-naive patients who started therapy with risperidone were recruited. The assessment involved anthropometric data (weight, height, BMI, BMI z-score and BMI percentile), cardiovascular parameters (blood pressure and QTc interval) and blood tests (levels of glucose, triglycerides, total cholesterol, glutamic oxaloacetic and pyruvic transaminases, &ggr;-glutamyl transferase, prolactin, free triiodothyronine, free thyroxine, thyroid-stimulating hormone, thyroglobulin, antithyroid peroxidase and antithyroglobulin). After an average follow-up of 6 months of risperidone therapy, a statistically significant increase in weight and body composition was observed. Furthermore, an increase in serum levels of prolactin was observed in 50% of patients. No other significant changes in metabolic and cardiovascular parameters were found. Although an increase in these parameters was detected, it remained in the normal range. This study suggests the use of specific protocols for monitoring children/adolescents treated with second-generation antipsychotics to manage the metabolic long-term complications and progression to more severe disease states.

Aggressive Behaviors and Verbal Communication Skills in Autism Spectrum Disorders

Aggressive behavior is a common problem among children with autism spectrum disorder (ASD) and could negatively affect family functioning and school and social competence. The aim of the present study was to investigate the relationship between aggressive behavior, such as self-aggression and other-aggression, with verbal communication ability and IQ level in children with ASD. The sample examined in this study included 88 children with a diagnosis of ASD. For the purposes of our study, much attention was focused on individual items of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview–Revised that were useful to evaluate the aggressive behavior. We have not found any association between aggressive behavior (other-aggression and self-aggression) and the absence of language or low IQ in children with ASD. Thus, the degree of severity of autism is probably the most important risk factor for this behavior.

Parenting stress among parents of children with Neurodevelopmental Disorders

In recent years, studies have shown that parents of children with Neurodevelopmental Disorders (NDDs) experience more parenting stress than parents of typically developing children, but the relation between the type of disorders and parenting stress is far from clear. The purpose of this study was to compare the parenting stress experienced by parents of 239 children with Specific Learning Disorders (SpLD), Language Disorders (LD), Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), and typical development (TD). Parents of children with NDDs experience more parenting stress than those of children who have TD. Although, parents of children with ASD or ADHD report the most high scores of parenting stress, also the parents of children with SpLD or LD report higher parental stress compared with parent of children without NDDs. Another interesting finding was that IQ level or emotional and behavioral problems are associated with the higher levels of parenting stress. This study suggest that parent, both mothers and fathers, of children with different type of NDDs should be provided with interventions and resources to empower them with the knowledge and skills to reduce their stress and to enhance their quality of life.

Psychopathology in children and adolescents with primary headaches: categorical and dimensional approaches.

Background Recurrent headache is common in childhood, but there is not a great amount of data on the associations between headaches and psychopathology in children. Objective The aim of this study is to examine the relationships between primary headaches and psychopathology in children, using both the categorical and dimensional assessment. Methods The sample consisted of 70 patients with primary headache compared to a matched sample of 50 healthy children. Psychiatric comorbidity was defined according to the diagnostic criteria of the Diagnostic and Statistical Manual of Disorders. Child psychopathology outcomes were assessed using child- and parent-reported standardized instruments. Results Internalizing and externalizing problems were significantly represented among children with headaches compared to the control group, respectively 63% and 27%, without significant differences between migraine and tension-type headache children. Moreover, a total of 26% of the children with a headache reported psychiatric comorbidity such as anxiety and mood disorders. Conclusion The dimensional approach improves accuracy in the recognition of emotional and behavioral problems compared to the categorical approach; however, the use of both of these approaches could be useful for clinical practice, treatment and research.

Mental health in migrant schoolchildren in Italy: teacher-reported behavior and emotional problems.

The migration process is a cause of physical and social stressors that may lead to mental health problems, particularly in children. In Italy, there are few studies about migrant children’s mental health; thus, the aim of this study is to compare the prevalence and types of emotional and behavioral problems in migrant schoolchildren to those of native Italian children. The research involved migrant (first- and second-generation) and native schoolchildren attending kindergarten, primary, and secondary school. A questionnaire was administered to parents to collect information about the sociodemographic characteristics of the children. All teachers filled in the Teacher’s Report Form for migrant and native children. The findings show that teachers detect academic and adaptive problems more easily in migrant schoolchildren, but they are probably less aware of the children’s psychological problems. The observations made in this study provide a starting point in understanding the psychological status and main problems noted among migrant children.

Aggressive behavior, cognitive impairment, and depressive symptoms in elderly subjects

Patients with dementia often have neuropsychiatric symptoms. The objective of this study was to evaluate the relationship between neuropsychiatric symptoms and progressive cognitive decline by assessing cognitive impairment, depressive symptoms, and aggressive behavior in a sample of elderly subjects. The study sample consisted of 201 subjects admitted to nursing homes. For the purpose of the present study each subject was evaluated using the Mini-Mental State Examination, the Geriatric Depression Scale, and the Modified Overt Aggression Scale. The results show that aggressive behavior and depressive symptoms are associated with progressive cognitive decline in elderly subjects. Early assessment of these conditions can promote rational therapeutic strategies that may improve the quality of life and delay institutionalization for elderly patients.

Ophthalmoplegic migraine: Migraine or oculomotor neuropathy?

Background Ophthalmoplegic migraine (OM) is a rare condition characterized by the association of headaches and an oculomotor nerve palsy. The third cranial nerve is commonly involved in recurrent attacks, whereas involvement of the sixth and fourth nerves is uncommon. It is still debated whether an uncontrolled migraine or an oculomotor neuropathy may be the primary cause of ophthalmoplegic migraine. Cases We report two patients affected by OM with normal magnetic resonance imaging findings and a history of uncontrolled migraine before an attack of OM. Conclusion The cases reported allow us to hypothesize that OM may be considered a form of migraine rather than a cranial neuralgia. It is possible that different factors such as inflammatory or structural factors, may represent a vulnerability of the nerve during a severe migraine attack causing ophthalmoplegia.
