Personality Characteristics and Neurocognitive Functions in Parents of Children with Autism Spectrum Disorder.

ABSTRACT: The increasing prevalence of autism spectrum disorder in children and the huge family burdens have caused concern in the academic field as well as society.To study the personality characteristics and neurocognitive functions in the Chinese parents of children with autism spectrum disorder (ASD) and compare them with the parents of well-developed children.This study recruited 41 Chinese children who met the diagnostic criteria of autism spectrum disorder according to Diagnostic and Statistical Manual of mental disorders-IV (DSM-IV). Their 79 biological parents were evaluated by means of Eysenck Personality Questionnaire (EPQ) and a set of neuropsychological tests. The normal control group consisted of 80 parents of well-developed children, and they were matched by age and gender.We found that the EPQ scores in the P scale for parents of children with ASD were significantly higher than the parents of well-developed children (t=1.68, p=0.039), while their scores in E scale and L scale were significantly lower (t=1.84, p=0.035; t=2.07, p=0.023). We also identified that the parents of children with ASD took significantly longer time than the normal control to complete Trail Making Test (TMT) Part A and Part B-M (t=1.57, p=0.013; t=0.83, p=0.019).Compared to the parents of well-developed children, the parents of children with ASD were more likely to be unconcerned, rigid, stubborn, introverted, and reticent. They displayed less novelty and thrill-seeking behaviors, and had limited social skills and maturity. Although the general cognitive functions including IQ were relatively intact in the parents of children with ASD, there were impairments in their planning, flexibility and visual processing functions.

Project description:Background:Genetic mosaicism is only detected occasionally when there are no obvious health or developmental issues. Most cases concern healthy parents in whom mosaicism is identified upon targeted testing of a genetic defect that was initially detected in their children. A germline genetic defect affecting the euchromatin histone methyltransferase 1 (EHMT1) gene causes Kleefstra syndrome, which is associated with the typical triad of distinct facial appearance, (childhood) hypotonia, and intellectual disability. A high degree of psychopathology is associated with this syndrome. A few parents with a mosaic EHMT1 mutation have been detected upon testing after a child was diagnosed with a germline EHMT1 defect. At first glance, carriers of a mosaic EHMT1 mutation appeared to function normally. However, recent studies have shown that de novo, postzygotic mutations in important developmental genes significantly contribute to autism spectrum disorder (ASD). Therefore, we hypothesized that EHMT1 mosaicism could cause neuropsychiatric defects. To investigate this, we performed a detailed investigation of cognitive neuropsychiatric parameters in parents identified with EHMT1 mosaicism. Methods:Three adults (two males, one female) with a genetically confirmed diagnosis of EHMT1 mosaicism were examined by means of a battery of tests and observational instruments covering both neurocognitive and psychiatric features. The battery included the following instruments: the Autism Diagnostic Observation Schedule (ADOS), the mini Psychiatric Assessment Schedules for Adults with Developmental Disabilities (mini PAS-ADD), the Vineland Adaptive Behavior Scales (VABS), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). These measures were compared with our previously reported data from Kleefstra syndrome patients with confirmed (germline) EHMT1 defects. Results:All three subjects achieved maximum total scores on the VABS, indicative of adequate (adaptive) functioning. In all, scores above cutoff were found on the ADOS for ASD and on the mini PAS-ADD for major depressive disorder (lifetime). Finally, results on the CANTAB showed impaired cognitive flexibility in all subjects. Conclusion:Individuals with EHMT1 mosaicism seem to have increased vulnerability for developing severe psychopathology, especially ASD and mood disorders. Although at first glance they appear to be well-adapted in their daily functioning, they may experience significant psychiatric symptoms and show reduced cognitive flexibility in comparison to the general population.

Project description:Background:Children diagnosed with autism spectrum disorder (ASD) have social and cognitive disabilities. For parents, these behaviors can lead to humiliation, social exclusion, and isolation. Stigma is a problem that not only may affect the individual with high functioning autism, but has the potential to extend to their family as well. Indeed, research indicates that the parents of children with disabilities (including ASD) commonly experience stigmatizing reactions from others. Aim of work:To determine the prevalence of self and enacted stigma among parents of ASD children from Riyadh, Saudi Arabia, and recognize possible risk factors and causes of stigmatization. Material and methods:An observational cross-sectional study involving the parents of ASD children from Riyadh, Saudi Arabia. About 163 participants were included from the Centre for Autism Research (CFAR) at King Faisal Specialist Hospital & Research Centre (KFSH & RC) in Riyadh. The primary material used for data collection was a five-point scale questionnaire developed by the investigator. The questionnaire consisted closed ended questions related to the participants' demographic data, autistic child, family life, resources, and social experiences as a parent. The collected data were analyzed using descriptive statistics and appropriate statistical analysis, using Statistical package for the social sciences (SPSS), version 22. The level of significance was P value?<?.05. Results:The findings of this work indicated that 55 (33.7%) of the parents scored more than 3 in answering questions related to felt stigma; 82 (50.3%) were fathers. On the other hand, 108 (66.3%) did not feel stigmatized being a parent of autistic child. Forty-two (25.8%) of the parents scored more than 3 in answering questions related to enacted stigma, whereas 121 (74.2%) did not face enacted stigmatization being a parent of autistic child. There was a strong tendency for mothers (41, 75%) to feel more self- and enacted stigmatized than fathers (P?<?.05). Moreover, the gender of the autistic child, consanguinity, severity of the ASD, and the monthly income of the family showed no significant difference in the parents who scored more than 3 for felt- or enacted stigmatization (P?>?.05). Conclusion:Among participated parents of children with ASD in Riyadh, Saudi Arabia, 33.7% of them experienced stigmatization, and mothers felt more self- and enacted stigmatized when compared to fathers. Public awareness among people in Saudi Arabia have been increased and, thus, negative stigmatization has decreased among parents in the country. A high level of felt stigma suggests the need for psychological intervention for the family to help cope with this new situation. A higher level of enacted stigma suggests the need for their rights (individuals with ASD) and increased awareness in the society. It is recommended that further research is needed in different centers in Riyadh and other regions of Saudi Arabia to investigate the prevalence of stigma in parents of autistic children.

Project description:Background:Lower gestational age may increase autism spectrum disorder (ASD) vulnerability; however, the incidence of ASD diagnosis through a direct assessment on every very preterm birth child on the population base remains unclear. Moreover, the behavioral characteristics of preterm birth ASD are unknown. Methods:Every very preterm birth child (gestational age <?32?weeks; birth weight <?1500?g) who was discharged from neonatal intensive care units in Southern Taiwan and prospectively followed to 5?years of age was evaluated using the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview-Revised (ADI-R). The term birth (gestational age >?37?weeks) ASD children characterized by ADOS and ADI-R were group matched to the preterm birth ASD by age at examination for comparison. ADOS severity scores were calculated by the Mann-Whitney U test and ADI-R by multivariate analysis of variance and canonical discriminant analysis. Results:Two hundred forty-six (87%) of the 283 very preterm survivors were followed prospectively to 5?years of age. Nineteen (7.7%) of the 246 children fulfilled the diagnostic criteria of ASD. After excluding 1 patient with cerebral palsy and profound mental disability, 18 preterm ASD children were compared with 44 term birth ASD children. The two ASD groups were comparable for age at examination, gender, and intelligence quotient. The two groups showed comparable ADOS severity scores in social affect deficits, restricted repetitive behaviors, and total score, but had differences in qualitative abnormalities in reciprocal social interaction (Wilks lambda F value?=?6.2, P?<?0.001) of ADI-R. Compared to term birth ASD children, preterm birth ASD children exhibited worse nonverbal behaviors that regulate social interaction (OR 2.59, 95% CI 1.41-4.73, P?=?0.002) but more favorable peer relationships (OR 0.58, 95% CI 0.38-0.90, P?=?0.01) and socioemotional reciprocity (OR 0.55, 95% CI 0.33-0.92, P?=?0.02). In contrast to the heterogeneous severity of social reciprocity in the term ASD group, the behavioral characteristics of the preterm ASD group showed a homogeneous reciprocal social interaction pattern. Conclusions:The 5-year incidence rate of ASD was high in very preterm birth children. Preterm birth ASD exhibited a specific behavioral phenotype of reciprocal social interaction.

Project description:ObjectivesTo estimate the prevalence of epilepsy in children with Autism Spectrum Disorder (ASD) and to determine the demographic and clinical characteristics of children with ASD and epilepsy in a large patient population.MethodsCross-sectional study using four samples of children with ASD for a total of 5,815 participants with ASD. The prevalence of epilepsy was estimated from a population-based sample. Children with and without epilepsy were compared on demographic and clinical characteristics. Multivariate logistic regression was used to examine the association between demographic and clinical characteristics and epilepsy.ResultsThe average prevalence of epilepsy in children with ASD 2-17 years was 12.5%; among children aged 13 years and older, 26% had epilepsy. Epilepsy was associated with older age, lower cognitive ability, poorer adaptive and language functioning, a history of developmental regression and more severe ASD symptoms. The association between epilepsy and the majority of these characteristics appears to be driven by the lower IQ of participants with epilepsy. In a multivariate regression model, only age and cognitive ability were independently associated with epilepsy. Children age 10 or older had 2.35 times the odds of being diagnosed with epilepsy (p<.001) and for a one standard deviation increase in IQ, the odds of having epilepsy decreased by 47% (p<.001).ConclusionThis is among the largest studies to date of patients with ASD and co-occurring epilepsy. Based on a representative sample of children with ASD, the average prevalence of epilepsy is approximately 12% and reaches 26% by adolescence. Independent associations were found between epilepsy and older age and lower cognitive ability. Other risk factors, such as poor language and developmental regression, are not associated with epilepsy after controlling for IQ. These findings can help guide prognosis and alert clinicians to patients with ASD who are at increased risk for epilepsy.

Project description:BackgroundIn recent years, parent-mediated intervention for children with autism spectrum disorder (ASD) has increased. Therefore, implementing effective parent training programs for parents of children with autism is of paramount importance, particularly in low- and middle-income countries. However, little is known about the status of and gaps in parents' knowledge on ASD, which may hinder the development of valid parental training programs. Herein, we aimed at exploring the status of Chinese parents' knowledge, attitude and behavior toward ASD, and potential factors affecting the acquisition of correct knowledge.MethodsThis study used a self-designed parental knowledge questionnaire of autism (PKQA) comprising 20 questions alongside another questionnaire comprising additional 17 questions covering the aspects of family demographics, attitudes, and behaviors of parents. In total, we included 394 parents who visited the outpatient department of the Child's Development and Behavior Center of the Third Affiliated Hospital of Sun Yat-Sen University between December 2018 and May 2019, with their children meeting the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnostic criteria for ASD.ResultsThe median knowledge score in the PKQA was 15 [interquartile range (IQR), 13-17]. Advanced paternal age and longer time interval from diagnosis to enrolling into the parent training program were associated with a lower total knowledge score (all P<0.001). Higher maternal education attainment, higher family income, child being currently under intervention, and family members sharing a common perception of the diagnosis were associated with a higher total knowledge score (all P<0.01). Reading autism-related books (P<0.001) or attending professional lectures (P=0.019) were also associated with a higher total knowledge score.ConclusionsTaken together, this study revealed that family demographics and parents' attitudes and behaviors toward ASD may significantly influence their knowledge about autism, suggesting the need for promoting more targeted parental skills training programs.
