Abstract
LAY ABSTRACT Gastrointestinal problems are common in the autism spectrum disorder community and may affect both the person with autism spectrum disorder and their families. However, little research is available on the experiences of families who have a child with both autism spectrum disorder and gastrointestinal symptoms. We held one-on-one interviews with 12 parents of children who had both autism spectrum disorder and gastrointestinal symptoms. We analyzed the raw text responses from these interviews and identified four main themes. First, parents shared that their children had trouble verbally communicating when they were experiencing gastrointestinal symptoms (Theme 1). This led parents to use bodily signs, such as changes in the stool, and non-verbal behaviors, such as irritability, to recognize when their child was having gastrointestinal symptoms. Next, gastrointestinal issues affected both the child's well-being and their ability to attend class and extracurricular or social activities (Theme 2). The gastrointestinal issues also affected the family's routines, overall well-being, and their ability to go out and do activities together as a family (Theme 3). Finally, parents often had challenges receiving accessible and quality healthcare for their child's gastrointestinal problems (Theme 4). Together, these findings highlight the enormous burden that gastrointestinal symptoms have on the wellness of children with autism spectrum disorder and their families.

Abstract
BACKGROUND Ninety percent of adults in the United States use the internet, and the majority of internet users report looking on the web for health information using search engines. The rising prevalence of autism spectrum disorder (ASD), uncertainty surrounding its etiology, and variety of intervention approaches contribute to questions about its causes and treatments. It is not known which terms people search most frequently about ASD and whether web search queries have changed over time. Infodemiology is an area of health informatics research using big data analytics to understand web search behavior. OBJECTIVE The objectives were to (1) use infodemiological data to analyze trends in web-based searches about the causes and treatments of ASD over time and (2) inform clinicians and ASD organizations about web queries regarding ASD. METHODS Google Trends was used to analyze web searches about the causes and treatments of ASD in the United States from 2004 to 2019. The search terms analyzed for queries about causes of ASD included vaccines, genetics, environmental factors, and microbiome and those for therapies included applied behavior analysis (ABA), gluten-free diet, chelation therapy, marijuana, probiotics, and stem cell therapy. RESULTS Google Trends results are normalized on a scale ranging from 0 to 100 to represent the frequency and relative interest of search topics. For searches about ASD causes, vaccines had the greatest frequency compared to other terms, with an initial search peak observed in 2008 (scaled score of 81), reaching the highest frequency in 2015 (scaled score of 100), and a current upward trend. In comparison, searches about genetics, environmental factors, and microbiome occurred less frequently. For web searches about ASD therapies, ABA consistently had a high frequency of search interest since 2004, reaching a maximum scaled score of 100 in 2019. The analyses of chelation therapy and gluten-free diet showed trending interest in 2005 (scaled score of 68) and 2007 (scaled score of 100), respectively, followed by a steady decline since (scaled scores of only 10 and 16, respectively, in 2019). Searches related to ASD and marijuana showed a rise in 2009 (scaled score of 35), and they continue to trend upward. Searches about probiotics and stem cell therapy have been relatively low (scaled scores of 22 and 18, respectively), but are gradually gaining interest. Web search volumes for stem cell therapy in 2019 surpassed both gluten-free diet and chelation therapy as web-searched interventions for ASD. CONCLUSIONS Google Trends is an effective infodemiology tool to analyze large-scale web search trends about ASD. The results showed informative variation in search trends over 15 years. These data are useful to inform clinicians and organizations about web queries on topics related to ASD, identify knowledge gaps, and target web-based education and knowledge translation strategies.

Abstract
The underlying mechanisms by which social support exerts its (typically) positive effects on parental wellbeing are still being investigated in the autism spectrum disorder (ASD) context. Parents (n = 674) of a child with ASD responded to questions probing parenting stress, parent psychological health, their child's ASD symptoms, and the types of social supports they were currently utilising. Hierarchical multiple linear regression analyses examined whether social support moderated or mediated (or neither) the relationships between: (a) parent-rated child ASD symptoms and parenting stress, and (b) parenting stress and parent psychological health. The main findings were that none of the mediating models reached statistical significance, while 7/20 moderation analyses were significant, though significance was dependent upon how social support was operationalised.

Parental satisfaction and perception of Progress in influencing the Practice of complementary health approaches in children with autism: a cross sectional survey from Negeri Sembilan, Malaysia. Altern Ther Health Med 2019; 19:250.

Abstract
Background Parents’ use of complementary health approaches (CHA) for children with autism spectrum disorder (ASD) are common despite the uncertain evidence of its benefit. Parents often adopt CHA due to dissatisfaction with conventional treatment. This study aimed to examine parents’ satisfaction with ASD treatment and their perception of progress in their child’s development. Parents’ use of CHA among children with ASD and the factors related were also evaluated. Methods Self-administered questionnaires were completed by 48 parents of children with ASD at a single tertiary referral hospital in Malaysia. Correlation analysis was used to explore associations between parental satisfaction scores, perception of progress scores and use of CHA. Results Use of CHA was reported by parents for 35.4% of children with ASD in the sample. Parents who were less satisfied with conventional treatment and parents who perceived poorer progress in their child’s development were more likely to use CHA. Strong positive relationship was found between parent satisfaction with ASD treatment scores and parent perception of progress scores, which indicates that parents who were satisfied with treatment were more likely to perceive greater progress in their child’s development. Improvement in child’s progress was most appreciated by parents in their child’s behavior (85.5%), social skills (83.3%) and motor skills (77.1%). Conclusion The use of CHA was common among children with ASD. Parents were more likely to practice CHA when they were less satisfied with conventional treatment and perceived poorer progress. A larger multicenter study is required to further explore the practice of CHA among children with ASD throughout Malaysia.

Abstract
This paper presents 6-month follow-up data of 44% (N = 64/116) of participants (ages 6-16 years) with a diagnosis of autism spectrum disorder, who participated in a previously-published randomized controlled trial of therapeutic horseback riding (THR) compared to a no-horse contact active control. The objective of this study was to examine whether significant improvements of irritability, hyperactivity, social, and communication behaviors observed in participants randomized to receive a 10-week manual-based THR intervention were sustained 6 months after the intervention conclusion. Participants' caregivers from both the THR (n = 36) and active control (n = 28) groups completed a measure of irritability and hyperactivity behaviors (primary outcome variables). Additionally, only the THR group participants completed the full battery of study outcomes assessments. Between group comparisons examining the extended interval from baseline (1-month pre-intervention assessment) to 6-months after the intervention revealed that the THR group maintained reductions in irritability behavior at a 0.1 level (effect size = 0.32, p = 0.07). (Effect size = 0.32, p = 0.07), which was 73% of efficacy preserved from the primary post-intervention endpoint (within 1-month post-intervention). Hyperactivity behaviors did not sustain this same trend. Comparisons from baseline and 6-months after the intervention revealed that the THR group sustained significant initial improvements made in social and communication behaviors, along with number of words and different words spoken during a standard language sample. This is the first known study to examine and demonstrate the longer-term effects of THR for individuals with ASD and warrants a more thorough evaluation of whether the effects of THR are maintained for at least 6-months after the intervention compared to a control.

Front Integr Neurosci 2018; 12:27. [PMID: 30038561 PMCID: PMC6046620 DOI: 10.3389/fnint.2018.00027] [Citation(s) in RCA: 45] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2018] [Accepted: 06/06/2018] [Indexed: 12/05/2022] Open
Abstract
Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder manifesting as lifelong deficits in social communication and interaction, as well as restricted repetitive behaviors, interests and activities. While there are no specific pharmacological or other physical treatments for autism, in recent years repetitive Transcranial Magnetic Stimulation (rTMS), a technique for non-invasive neuromodulation, has attracted interest due to potential therapeutic value. Here we report the results of a systematic literature review and meta-analysis on the use of rTMS to treat ASD. Methods: We performed a systematic literature search on PubMed, Web of Science, Science Direct, Bielefeld Academic Search, and Educational Resources Information Clearinghouse. Search terms reflected diagnoses and treatment modalities of interest. Studies reporting use of rTMS to treat core ASD or cognitive symptoms in ASD were eligible. Two researchers performed article selection and data extraction independently, according to PRISMA guidelines. Changes in ASD clinical scores or in cognitive performance were the main outcomes. Random effects meta-analysis models were performed. Results: We found 23 eligible reports, comprising 4 case-reports, 7 non-controlled clinical trials, and 12 controlled clinical trials, comparing the effects of real TMS with waiting-list controls (n = 6) or sham-treatment (n = 6). Meta-analyses showed a significant, but moderate, effect on repetitive and stereotyped behaviors, social behavior, and number of errors in executive function tasks, but not other outcomes. Most studies had a moderate to high risk of bias, mostly due to lack of subject- and evaluator-blinding to treatment allocation. Only 5 studies reported stability of these gains for periods of up 6 months, with descriptions that improvements were sustained over time. Conclusions: Existing evidence supports that TMS could be useful to treat some dimensions of ASD. However, such evidence must be regarded with care, as most studies did not adequately control for placebo effects. Moreover, little is known regarding the most effective stimulation parameters, targets, and schedules. There is an urgent need for further randomized, double-blind, sham-controlled trials, with adequate follow-up periods, to test the efficacy of transcranial magnetic stimulation to treat these disorders. Available evidence must be regarded as preliminary and insufficient, at present, to support offering TMS to treat ASD.

Abstract
Variation in parental beliefs about Autism Spectrum Disorder (ASD) may impact subsequent service use profiles. This study aimed to examine (1) variation in beliefs about ASD among English language proficient White (EP-W) mothers, English language proficient Latino (EPL) mothers, and limited English language proficient Latino (LEP-L) mothers of children with ASD; (2) variation in beliefs about ASD in the context of the child's ASD severity, among EP White mothers, EP Latino others, and LEP Latino mothers; and (3) potential links between maternal beliefs about ASD and children's current ASD treatment. This multi-site study included 305 English or Spanish-speaking parents of children with ASD, ages 2-10 years, who completed a survey about their beliefs about their child's ASD, their child's ASD severity, and treatments used by their children. Results showed that mothers in the EP-W, EP-L, and LEP-L groups differed in their beliefs about viewing ASD as a mystery. Only maternal views of ASD severity in the EP-W group were linked to their beliefs about ASD. Finally, maternal beliefs about ASD having major consequences on their child's life, and ASD being a mystery were strongly associated with a child's use of ASD intervention services. These findings provide new knowledge of how maternal beliefs about ASD vary in linguistically diverse groups, how a child's ASD severity may influence such beliefs, and how maternal beliefs correlate with the amount of therapy children with ASD receive. Future research should address how these beliefs or views are formed, what factors influence them, or whether they are malleable. Understanding parents' beliefs or views of having a child with ASD can potentially help us increase use of ASD intervention services in families of children with ASD.

Abstract
We compared anthropometric values, nutrient intake, the Healthy Eating Index and food variety in children with autism spectrum disorder (ASD), 20 on a gluten-free casein-free (GFCF) diet and 85 on a regular diet in Valencia (Spain) using 3-days food diaries. Those on the GFCF diet had a lower weight, body mass index, and total energy, pantothenic acid, calcium, phosphorus and sodium intake, but a higher intake of fiber, legumes, and vegetables. Further, the GFCF diet group had a better quality of fat intake, but needed supplementation with vitamin D. Randomized controlled trials are required to explore long-term effects of this diet on anthropometric and nutritional status (the focus of our study), but also behavioral symptoms, in children with ASD.

Abstract
The phrase primum non nocere ("first, do no harm") is a well-accepted credo of the medical and mental health professions. Although emerging data indicate that several psychological treatments may produce harm in significant numbers of individuals, psychologists have until recently paid little attention to the problem of hazardous treatments. I critically evaluate and update earlier conclusions regarding deterioration effects in psychotherapy, outline methodological obstacles standing in the way of identifying potentially harmful therapies (PHTs), provide a provisional list of PHTs, discuss the implications of PHTs for clinical science and practice, and delineate fruitful areas for further research on PHTs. A heightened emphasis on PHTs should narrow the scientist-practitioner gap and safeguard mental health consumers against harm. Moreover, the literature on PHTs may provide insight into underlying mechanisms of change that cut across many domains of psychotherapy. The field of psychology should prioritize its efforts toward identifying PHTs and place greater emphasis on potentially dangerous than on empirically supported therapies.

Abstract
Autism spectrum disorders (ASDs) are considered a heterogenous set of neurobehavioral diseases, with the rates of diagnosis dramatically increasing in the past few decades. As genetics alone does not explain the underlying cause in many cases, attention has turned to environmental factors as potential etiological agents. Gastrointestinal disorders are a common comorbidity in ASD patients. It was thus hypothesized that a gut-brain link may account for some autistic cases. With the characterization of the human microbiome, this concept has been expanded to include the microbiota-gut-brain axis. There are mounting reports in animal models and human epidemiologic studies linking disruptive alterations in the gut microbiota or dysbiosis and ASD symptomology. In this review, we will explore the current evidence that gut dysbiosis in animal models and ASD patients correlates with disease risk and severity. The studies to date have surveyed how gut microbiome changes may affect these neurobehavioral disorders. However, we harbor other microbiomes in the body that might impact brain function. We will consider microbial colonies residing in the oral cavity, vagina, and the most recently discovered one in the placenta. Based on the premise that gut microbiota alterations may be causative agents in ASD, several therapeutic options have been tested, such as diet modulations, prebiotics, probiotics, synbiotics, postbiotics, antibiotics, fecal transplantation, and activated charcoal. The potential benefits of these therapies will be considered. Finally, the possible mechanisms by which changes in the gut bacterial communities may result in ASD and related neurobehavioral disorders will be examined.

Abstract
There are many treatments in current use for core and associated symptoms of autism spectrum disorders (ASD). This review discusses the complementary and alternative medical (CAM) treatments commonly added to conventional interventions for children with ASD, including natural products, mind and body practices, and other biomedical treatments. The article focuses on factors associated with use of CAM, the empirical evidence for the most frequently used treatments, and how clinicians work with families who choose CAM treatments. Some treatments have been ineffective, some have unacceptable potential side effects, and others require more study in depth.

Abstract
In autism spectrum disorders, many parents resort to alternative treatments and these are generally perceived as risk free. Among these, the most commonly used is the gluten-free, casein-free diet. The objective of this work was to conduct a systematic review of studies published from 1970 to date related to the gluten-free, casein-free diet in autism spectrum disorder patients. Few studies can be regarded as providing sound scientific evidence since they were blinded randomized controlled trials, and even these were based on small sample sizes, reducing their validity. We observed that the evidence on this topic is currently limited and weak. We recommend that it should be only used after the diagnosis of an intolerance or allergy to foods containing the allergens excluded in gluten-free, casein-free diets. Future research should be based on this type of design, but with larger sample sizes.

Abstract
BACKGROUND Subjects with autism spectrum disorders (ASDs) often exhibit behavioral symptoms such as aggressiveness and irritability. The purpose of this study was to examine the efficacy and the tolerability of aripiprazole switched from risperidone in children and adolescents with ASD. METHODS This prospective, 12-week, open-label study included 9 male subjects with ASD (age range, 9-22 years; mean ± SD age, 14.8 ± 4.0 years) followed up for 12 weeks after switching to aripiprazole from risperidone. The primary outcome measures were the Clinical Global Impression-Improvement scales and the irritability subscale of the Aberrant Behavior Checklist. RESULTS The mean ± SD maintenance dosages of risperidone and aripiprazole were 0.6 ± 0.4 mg/d and 4.8 ± 4.0 mg/d, respectively. The mean ± SD scores of the irritability subscale of the Aberrant Behavior Checklist before switching to aripiprazole (baseline) and 12 weeks after switching to aripiprazole (end point) were 14.8 ± 7.6 and 13.1 ± 8.0, respectively. The mean ± SD Clinical Global Impression-Improvement score, a comparison from baseline to end point, was 2.4 ± 0.7. Mild somnolence was observed only in 1 subject. No significant changes in vital signs, weight, electrocardiogram, or laboratory measures occurred during switching to aripiprazole. Serum prolactin levels decreased significantly from 17.3 ± 9.4 ng/mL (baseline) to 2.3 ± 1.7 ng/mL (end point). CONCLUSIONS The results show that aripiprazole might be generally well tolerated and might constitute an alternative treatment of subjects with ASD who experience poor efficacy or tolerability issues with risperidone treatment. Additional long-term controlled studies are needed to evaluate the efficacy and the safety of switching to aripiprazole from other antipsychotics in subjects with ASD.

Abstract
A diagnosis of autistic spectrum disorder (ASD), now estimated to affect one in 88 children, requires deficits in social communication and interactions, and restricted interests and/or repetitive behaviors. Almost all children with ASD have deficits in adaptive skills, many have intellectual disability, and others have co-occurring psychiatric disorders or symptoms. Thus, this complex disorder has shown to have a substantial impact on patients' quality of life (QoL) and that of their families. Medication treatment is considered by clinicians and families to address problems with functioning due to psychiatric problems, and, as such, one-third of children and adolescents with ASD take at least one psychotropic medication and many use complementary and alternative medicine. This paper reviews what is known about the benefits and risks of psychotropic medications on the QoL of children with ASD. Although scarce, there are studies of psychiatric medications in autistic patients that include QoL measures, such as the pediatric studies of aripiprazole for irritability and one adult study of oxytocin. The aripiprazole study showed a positive effect on QoL in treated patients, as did the oxytocin study. Several other psychotropic medications are used in the treatment of children with ASD, and although information is available on the risks and benefits of each, we do not have specific data on the QoL impact of these medications. The aripiprazole and oxytocin studies exemplify how researchers can include QoL measures and use this information to guide clinicians. Additionally, we will recommend areas of further study in pharmacotherapy and QoL research in the context of treating children with ASD.

Utilization patterns of conventional and complementary/alternative treatments in children with autism spectrum disorders and developmental disabilities in a population-based study. J Dev Behav Pediatr 2014; 35:1-10.

Abstract
OBJECTIVE To compare the utilization of conventional treatments and utilization of complementary and alternative medicine in preschoolers with autism spectrum disorders (ASD) and other developmental disabilities (DD). METHODS Participants were 578 children who were part of an ongoing population-based, case-control study of 2- to 5-year olds with ASD, DD, and the general population. Parents completed an interview on past and current services. RESULTS Four hundred fifty-three children with ASD and 125 DD children were included. ASD families received more hours of conventional services compared with DD families (17.8 vs 11; p < .001). The use of psychotropic medications was low in both groups (approximately 3%). Overall, complementary and alternative medicine (CAM) use was not significantly different in ASD (39%) versus DD (30%). Hispanic families in both groups used CAM less often than non-Hispanic families. Variables such as level of function, immunization status, and the presence of an identified neurogenetic disorder were not predictive of CAM use. A higher level of parental education was associated with an increased CAM use in ASD and DD. Families who used >20 hours per week of conventional services were more likely to use CAM, including potentially unsafe or disproven CAM. Underimmunized children were marginally more likely to use CAM but not more likely to have received potentially unsafe or disproven CAM. CONCLUSION Use of CAM is common in families of young children with neurodevelopmental disorders, and it is predicted by higher parental education and non-Hispanic ethnicity but not developmental characteristics. Further research should address how health care providers can support families in making decisions about CAM use.

Abstract
Response to early intervention programs in autism is variable. However, the factors associated with positive versus poor treatment outcomes remain unknown. Hence the issue of which intervention/s should be chosen for an individual child remains a common dilemma. We argue that lack of knowledge on "what works for whom and why" in autism reflects a number of issues in current approaches to outcomes research, and we provide recommendations to address these limitations. These include: a theory-driven selection of putative predictors; the inclusion of proximal measures that are directly relevant to the learning mechanisms demanded by the specific educational strategies; the consideration of family characteristics. Moreover, all data on associations between predictor and outcome variables should be reported in treatment studies.

Abstract
AIM In this study polyphenols from pomegranate peel, and n-3 fatty acids with polyphenols from flax seed were evaluated for their anti depression properties in mice exposed to chronic mild stress (CMS). METHODS A total of 40 mice initially trained to consume 2% sucrose solution for 3 weeks were then divided into five groups of eight each. The first group was the normal control, the remaining four groups were exposed to CMS but were force fed with either: 10 mL water per kg bodyweight per day; imipramine (a standard antidepressant) 15 mg kg bodyweight; 30 mg per kg bodyweight polyphenol equivalent extract from pomegranate peel; or 30 mg polyphenols per kg bodyweight with omega-3 fatty acids present, for 50 days. At the end, blood and brain were analyzed for various biomarkers of depression. RESULTS The flax seed and imipramine groups had significantly increased sucrose consumption, decreased cortisol (blood), decreased epinephrine and norepinephrine concentration, decreased monoamine oxidase A and B activity, and decreased superoxide dismutase activity. Lipid peroxidation was completely inhibited. In contrast, pomegranate peel extract also completely inhibited lipid peroxidation in the brain, and reduced enzyme activity and hormone concentration but to a lesser extent than flax seed. CONCLUSION Polyphenols from flax seed with omega-3 fatty acids were able to reduce all the CMS effects tested compared to polyphenols from pomegranate peel.

Abstract
Anthropometric development and growth were assessed in 2 groups of 6- to 9-year-olds: children with autism spectrum disorders and typically developing children. In a case-control study conducted in Valencia, Spain, we compared the body mass index (kg/m(2)) of 40 children with autism spectrum disorders (cases) and 113 typically developing children (controls) from the same area of residence. The sex- and age-adjusted odds ratios for being underweight in cases was 2.41 compared to controls. Furthermore, the body mass index distribution of the cases was significantly offset to lower values with respect to that of the controls (P = .024). In particular, 20% of the cases had a body mass index below the fifth percentile versus just 8.85% of the controls. Our data suggest that the anthropometric development of children with autism spectrum disorders should be monitored as part of routine care.

Abstract
INTRODUCTION This study examined the prevalence of the use of different complementary and alternative medicine (CAM) strategies, families' attitudes and belief systems about the use of these strategies, and the economic burden of these strategies placed on family income in families of children with autism spectrum disorders (ASD). METHOD A questionnaire survey concerning the use of CAM in children with ASD was administered to parents in the five different geographic locations in Turkey. RESULT Of the 172 respondents, 56% had used at least one CAM therapy. The most frequently used CAM intervention was spiritual healing. Among the most reported reasons for seeking CAM were dissatisfaction with conventional interventions and a search for ways to enhance the effectiveness of conventional treatments. The most frequently reported source of recommendation for CAM was advice from family members. The mean economic burden of the CAM methods was a total of 4,005 Turkish lira ($2,670) in the sample using CAM. The CAM usage rate was lower in parents who suspected genetic/congenital factors for the development of ASD. CONCLUSION This study observed the importance of socioeconomic and cultural factors as well as parents' beliefs about the etiology of ASD in treatment decisions about CAM.

Abstract
This article provides a conceptual overview for the use of biomedical complementary and alternative medicine (CAM) treatments for autism spectrum disorders. Pharmaceutical agents with published studies are briefly mentioned; but the focus of the article is on possible biomedical CAM treatments, the rationale for their use, and the current database of mostly preliminary studies regarding their safety and efficacy. Of the more than 50 treatments currently listed here and in use by eager families, 9 are reviewed in more detail because of their promise from preliminary research studies or because of public interest.

Abstract
The Internet is a major source of health-related information for parents of sick children despite concerns surrounding quality. For neurodevelopmental disorders, the websites of advocacy groups are a largely unexamined source of information. We evaluated treatment information posted on nine highly-trafficked advocacy websites for autism, cerebral palsy, and fetal alcohol spectrum disorder. We found that the majority of claims about treatment safety and efficacy were unsubstantiated. Instead, a range of rhetorical strategies were used to imply scientific support. When peer-reviewed publications were cited, 20 % were incorrect or irrelevant. We call for new partnerships between advocacy and experts in developmental disorders to ensure better accuracy and higher transparency about how treatment information is selected and evidenced on advocacy websites.

Abstract
The use of complementary and alternative interventions is growing and gaining popularity, both in the UK and internationally, with significant financial and emotional implications. Complementary and alternative interventions are often utilised by parents of children with Autistic Spectrum Disorders and research has investigated parental beliefs. There is, however, limited understanding regarding what professionals believe about the use of alternative treatments. In this paper we explore the opinions of a range of different professionals about alternative treatments and found that while some have an open-minded opinion, there was a tendency to hold beliefs that these treatments are ineffective, that they give false hope and have potential to harm the child. We discuss the implications for this in terms of the importance of an open dialogue between professionals and families and consider the importance of this in relation to the popularity of these interventions.

Abstract
Little research has been conducted on behavioral characteristics of children with autism spectrum disorder (ASD) from diverse cultures within the US, or from countries outside of the US or Europe, with little reliable information yet reported from developing countries. We describe the process used to engage diverse communities in ASD research in two community-based research projects-an epidemiologic investigation of 7- to 12-year olds in South Korea and the Early Autism Project, an ASD detection program for 18- to 36-month-old Zulu-speaking children in South Africa. Despite the differences in wealth between these communities, ASD is underdiagnosed in both settings, and generally not reported in clinical or educational records. Moreover, in both countries, there is low availability of services. In both cases, local knowledge helped researchers to address both ethnographic as well as practical problems. Researchers identified the ways in which these communities generate and negotiate the cultural meanings of developmental disorders. Researchers incorporated that knowledge, as they engaged communities in a research protocol, adapted and translated screening and diagnostic tools, and developed methods for screening, evaluating, and diagnosing children with ASD.

Abstract
BACKGROUND Subjects with Pervasive Developmental Disorders (PDD) often exhibit behavioral symptoms such as aggressiveness and irritability, which are targets of psychopharmacologic intervention. This retrospective study was designed to examine children and adolescents with PDD experiencing tolerability issues with risperidone treatment, and thereby assess the efficacy and tolerability of switching to aripiprazole. METHODS This naturalistic study included 23 subjects with PDD (16 males, 7 females, age range 9-24 years, mean age 15.1±3.9 years) diagnosed according to DSM-IV criteria and followed up for 14.9±8.4 weeks after switching to aripiprazole from risperidone. Outcome measures were the Clinical Global Impression-Severity (CGI-S) and CGI Improvement (CGI-I) scales. RESULTS The mean CGI-S scores of pre-aripiprazole treatment and post-aripiprazole treatment were, respectively 4.7±1.4 and 4.6±1.3. Mean maintenance dosages of risperidone and aripiprazole were, respectively, 0.7±0.5mg/day and 2.8±1.3mg/day. The mean CGI-I score, which shows the difference induced by switching from risperidone to aripiprazole, was 3.4±0.8 for the whole sample, suggesting that the efficacy of risperidone for treating behavioral problems of PDD was maintained by aripiprazole. Some improvement of safety/tolerability issues such as increased appetite, somnolence, hyperprolactinemia, and amenorrhea occurred after switching to aripiprazole. CONCLUSION Results show that switching to aripiprazole might be generally well tolerated and might constitute an alternative treatment for subjects with PDD who experience tolerability issues with risperidone treatment. Additional long-term controlled studies of PDD subjects should be undertaken to evaluate the efficacy and safety of switching to aripiprazole from other antipsychotics.

Abstract
The application of carnosine in medicine has been discussed since several years, but many claims of therapeutic effects have not been substantiated by rigorous experimental examination. In the present perspective, a possible use of carnosine as an anti-neoplastic therapeutic, especially for the treatment of malignant brain tumours such as glioblastoma is discussed. Possible mechanisms by which carnosine may perform its anti-tumourigenic effects are outlined and its expected bioavailability and possible negative and positive side effects are considered. Finally, alternative strategies are examined such as treatment with other dipeptides or β-alanine.

Abstract
Developmental disorders (DDs) are important leading cause of disability in developed countries and also in the United States. DDs are a group of individual conditions that result from abnormal nervous system development and cause altered function. They can begin at any time from prenatal to 22 years of age and the disability usually presents itself throughout a person's life time. Down syndrome, autism, neural tube defects, schizophrenia, cretinism, and attention-deficit hyperactivity disorder are among the most common DDs that currently plague numerous countries and have varying incidence rates. Their occurrence may be partially attributable to the lack of certain dietary nutrients. Notably, essential vitamins, minerals, and ω-3 fatty acids are often deficient in the general population of America and developed countries and are exceptionally deficient in patients suffering from mental disorders. Typically, most of these disorders are treated with prescription drugs, but many of these drugs cause unwanted side effects. Therefore, psychiatrists recommend alternative or complementary nutritional remedies to overcome the adverse effects of those drugs. Studies have shown that daily supplements of vital nutrients, such as that contain amino acids, often effectively reduce symptoms of the patients, because they are converted into neurotransmitters that alleviate depression and other mental disorders. The aim of this article is to discuss the role of dietary imbalances in the incidence of DD and to emphasize which dietary supplements can aid in the treatment of the above-mentioned DD.

Abstract
Discussions and debates have recently emerged on the potential positive and negative effects of cow's milk in the paediatric community, also under the pressure of public opinion. The negative effects of cow's-milk consumption seem to be limited to iron status up to 9 to 12 months; then no negative effects are observed, provided that cow's milk, up to a maximum daily intake of 500 mL, is adequately complemented with iron-enriched foods. Lactose intolerance can be easily managed and up to 250 mL/day of milk can be consumed. Allergy to cow's-milk proteins is usually transient. Atopic children may independently be at risk for poor growth, and the contribution of dairy nutrients to their diet should be considered. The connection of cow's milk to autistic spectrum disorders is lacking, and even a cause-effect relation with type 1 diabetes mellitus has not been established because many factors may concur. Although it is true that cow's milk stimulates insulin-like growth factor-1 and may affect linear growth, association with chronic degenerative, noncommunicable diseases has not been established. Finally, fat-reduced milk, if needed, should be considered after 24 to 36 months. Cow's milk represents a major source of high nutritional quality protein as well as of calcium. Moreover, it has growth-promoting effects independent of specific compounds. Its protein and fat composition, together with the micronutrient content, is suggestive of a functional food, whose positive effects are emphasised by regular consumption, particularly under conditions of diets poor in some limiting nutrients, although in industrialised countries cow's milk's optimal daily intake should be around 500 mL, adequately complemented with other relevant nutrients.

DESIGN A within-subject analysis comparing pre- to post-treatment scores on two standard measures of childhood behavioral problems was used. SETTINGS AND LOCATION: The intervention and data analysis occurred at a tertiary care, medical school teaching hospital. SUBJECTS Twenty-four (24) children aged 3-16 years with a diagnosis of an ASD comprised the study group. INTERVENTION The efficacy of an 8-week multimodal yoga, dance, and music therapy program based on the relaxation response (RR) was developed and examined. OUTCOME MEASURES The study outcome was measured using The Behavioral Assessment System for Children, Second Edition (BASC-2) and the Aberrant Behavioral Checklist (ABC). RESULTS Robust changes were found on the BASC-2, primarily for 5-12-year-old children. Unexpectedly, the post-treatment scores on the Atypicality scale of the BASC-2, which measures some of the core features of autism, changed significantly (p=0.003). CONCLUSIONS A movement-based, modified RR program, involving yoga and dance, showed efficacy in treating behavioral and some core features of autism, particularly for latency-age children.

Abstract
OBJECTIVE This report presents a case of a 9-year-old boy with autism that responded positively to nutritional supplements. METHODS The supplements were dimethylglycine and a combination of a large dose of vitamin B6 (pyridoxal HCl) and magnesium. The Autism Treatment Evaluation Checklist (ATEC) was used for outcome assessment and administered by 2 of his family members both before the nutritional supplements and 5 months into the supplements, thereby referred to as pretest and post-test, respectively. Two (2) assessors independently performed evaluations. The ATEC evaluates four areas: communication, sociability, sensory/cognitive awareness, and behavior. The lower the scores are, the less severe the symptoms are. RESULTS The ATEC evaluations by 2 independent assessors showed that the changes in total ATEC were from 63 at pretest to 33 at post-test, and from 64 at pretest to 30 at post-test, respectively. These changes represented reductions of 47.6% and 53.1%. A strong inter-rater reliability was demonstrated, with an intraclass correlation coefficient of 0.988. The school teachers also noticed improvements in various areas consistent with the ATEC evaluations. CONCLUSIONS Although the reported findings cannot be generalized, this case report provides useful preliminary evidence to an accumulating body of literature supporting the theory and efficacies of nutritional supplements in autism-spectrum disorders.

Dysautonomia in autism spectrum disorder: case reports of a family with review of the literature. AUTISM RESEARCH AND TREATMENT 2011; 2011:129795. [PMID: 22937241 PMCID: PMC3420600 DOI: 10.1155/2011/129795] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/07/2010] [Accepted: 04/10/2011] [Indexed: 11/18/2022]
Abstract
Case histories of a mother and her two children are reported. The mother was a recovered alcoholic. She and her two children, both of whom had symptoms that are typical of autistic spectrum disorder, had dysautonomia. All had intermittently abnormal erythrocyte transketolase studies indicating abnormal thiamine pyrophosphate homeostasis. Both children had unusual concentrations of urinary arsenic. All had symptomatic improvement with diet restriction and supplementary vitamin therapy but quickly relapsed after ingestion of sugar, milk, or wheat. The stress of a heavy metal burden, superimposed on existing genetic or epigenetic risk factors, may be important in the etiology of autism spectrum disorder when in combination. Dysautonomia has been associated with several diseases, including autism, without a common etiology. It is hypothesized that oxidative stress results in loss of cellular energy and causes retardation of hard wiring of the brain in infancy, affecting limbic system control of the autonomic nervous system.

Abstract
OBJECTIVES To explore the relationship between causal beliefs on autism (CBA) and treatment choices. DESIGN AND METHODS A cross-sectional design was employed. Parents of a child with autism spectrum disorder (ASD) were asked to complete the Lay-Beliefs about Autism Questionnaire (LBA-Q) and answer questions about treatments used. Only items inquiring about a cause of autism were retained for analysis. Series of forward stepwise logistic regressions were performed with each treatment as dependent variable and the scores given to each of the CBA items as independent variables. RESULTS 78 parents were included. The most strongly held causal beliefs were brain abnormalities and genetic factors. Parents who had more beliefs in the causal role of very early traumatic experiences were less likely to use behavior therapy and PECS. Higher beliefs in illness during pregnancy increased the odds of medication use. Stronger beliefs on the role of food allergy were associated with higher use of detoxification treatments, special diets, and vitamins. On the contrary, these beliefs reduced the odds of drug use. CONCLUSIONS Causal beliefs are associated with treatment choices. Such preliminary results highlight the value of continued studies, not only to establish the causal nature of these associations, but also to demonstrate the utility of modifying such beliefs for both parents' and child's benefits. Identifying parents' beliefs about their child's illness may be an important step in formulating interventions facilitating appropriate care.

Abstract
BACKGROUND Autism is a complex neurodevelopmental disorder that forms part of a spectrum of related disorders referred to as Autism Spectrum Disorders. The present study assessed the effects of topiramate plus risperidone in the treatment of autistic disorder. METHOD Forty children between the ages of 4 and 12 years with a DSM IV clinical diagnosis of autism who were outpatients from a specialty clinic for children were recruited. The children presented with a chief complaint of severely disruptive symptoms related to autistic disorder. Patients were randomly allocated to topiramate+risperidone (Group A) or placebo+risperidone (Group B) for an 8-week, double-blind, placebo-controlled study. The dose of risperidone was titrated up to 2 mg/day for children between 10 and 40 kg and 3 mg/day for children weighting above 40 kg. The dose of topiramate was titrated up to 200 mg/day depending on weight (100 mg/day for <30 kg and 200 mg/day for >30 kg). Patients were assessed at baseline and after 2, 4, 6 and 8 weeks after starting medication. Measure of outcome was the Aberrant Behavior Checklist-Community (ABC-C) Rating Scale. RESULTS Difference between the two protocols was significant as the group that received topiramate had a greater reduction in ABC-C subscale scores for irritability, stereotypic behavior and hyperactivity/noncompliance. CONCLUSION The results suggest that the combination of topiramate with risperidone may be superior to risperidone monotherapy for children with autistic disorder. However the results need to be further confirmed by a larger randomized controlled trial.

Pyrosequencing study of fecal microflora of autistic and control children. Anaerobe 2010; 16:444-53.

Abstract
There is evidence of genetic predisposition to autism, but the percent of autistic subjects with this background is unknown. It is clear that other factors, such as environmental influences, may play a role in this disease. In the present study, we have examined the fecal microbial flora of 33 subjects with various severities of autism with gastrointestinal symptoms, 7 siblings not showing autistic symptoms (sibling controls) and eight non-sibling control subjects, using the bacterial tag encoded FLX amplicon pyrosequencing (bTEFAP) procedure. The results provide us with information on the microflora of stools of young children and a compelling picture of unique fecal microflora of children with autism with gastrointestinal symptomatology. Differences based upon maximum observed and maximum predicted operational taxonomic units were statistically significant when comparing autistic and control subjects with p-values ranging from <0.001 to 0.009 using both parametric and non-parametric estimators. At the phylum level, Bacteroidetes and Firmicutes showed the most difference between groups of varying severities of autism. Bacteroidetes was found at high levels in the severely autistic group, while Firmicutes were more predominant in the control group. Smaller, but significant, differences also occurred in the Actinobacterium and Proteobacterium phyla. Desulfovibrio species and Bacteroides vulgatus are present in significantly higher numbers in stools of severely autistic children than in controls. If the unique microbial flora is found to be a causative or consequent factor in this type of autism, it may have implications with regard to a specific diagnostic test, its epidemiology, and for treatment and prevention.

Abstract
This review focuses on helping clinicians identify resources and develop strategies they may use to effectively negotiate safe and effective use of complementary and alternative medicine (CAM) treatments with families of children with autism spectrum disorders (ASD), as well as other neurodevelopmental disorders. Since new types of CAM continue to be introduced into the autism community, emphasis is placed on providing clinicians with tools to help families negotiate the myriad of available treatments and make decisions based on current safety and efficacy data, while remaining mindful of the reasons families may be considering these treatments. We familiarize readers with high-quality, evidence-based resources that providers and families may use to ascertain current information about specific types of CAM, verify the content of biologically-based treatments, identify ongoing CAM research and obtain toolkits designed to help healthcare providers raise the topic of CAM usage and facilitate disclosure and discussion of CAM use with patients and their families.

Abstract
BACKGROUND There are several lines of evidence to indicate that the immune system plays an important role in the pathophysiology of autism. The objective of this study was to access the effects of pentoxifylline plus risperidone in the treatment of autistic disorder. METHODS Forty children between the ages 4 and 12 years with a DSM IV-TR clinical diagnosis of autism were recruited. The children presented with a chief complaint of severely disruptive symptoms related to autistic disorder. Patients were randomly allocated to pentoxifylline+risperidone or placebo+risperidone for a 10-week, double-blind, placebo-controlled study. The dose of risperidone was titrated up to 3 mg/day, pentoxifylline was titrated to 600 mg/day. Patients were assessed at baseline and after 2, 4, 6, 8 and 10 weeks of starting medication. The measure of the outcome was the Aberrant Behavior Checklist-Community (ABC-C). RESULTS The difference between the two protocols was significant as the group that received pentoxifylline had greater reduction in ABC-C subscale scores for Irritability, Lethargy/Social Withdrawal, Stereotypic Behavior, Hyperactivity/Noncompliance and Inappropriate Speech. CONCLUSION The results suggest that combination of atypical antipsychotic medications and pentoxifylline might have synergistic effects in treatment of behavioral problems of children with autism.

Abstract
Probiotic bacteria, commensals selected for their presumed therapeutic properties when ingested orally, have attracted increasing attention for their possible efficacy in a range of gastrointestinal disorders, including the inflammatory bowel diseases of Crohn's disease and ulcerative colitis. Since the barrier properties of the intestinal epithelium are believed to be compromised as a consequence (or perhaps as a cause) of intestinal inflammation, we hypothesized that probiotics might ameliorate such epithelial dysfunction as part of their spectrum of beneficial effects. We have used both cell line and animal models to test this hypothesis and show that two probiotics have significant effects on epithelial barrier properties, both at baseline and when deranged by inflammatory cytokines or in the setting of inflammation in a mouse model of colitis. Moreover, the probiotics also normalize epithelial ion transport function, which could also contribute to clinical efficacy. Overall, our studies extend the spectrum of functional effects attributable to probiotics, and may provide a rationale for their use in a range of gastrointestinal disorders associated with epithelial dysfunction.

Abstract
OBJECTIVE To determine whether children with autism have an increased incidence of gastrointestinal symptoms compared with matched control subjects in a population-based sample. DESIGN/METHODS In a previous study including all of the residents of Olmsted County, Minnesota, aged <21 years between 1976 and 1997, we identified 124 children who fulfilled criteria on the basis of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, for a research diagnosis of autism. Two matched control subjects were identified for each case subject. Through the Rochester Epidemiology Project, all medical diagnoses, are indexed for computerized retrieval. Gastrointestinal diagnoses before 21 years of age were grouped into 5 categories: (1) constipation; (2) diarrhea; (3) abdominal bloating, discomfort, or irritability; (4) gastroesophageal reflux or vomiting; and (5) feeding issues or food selectivity. The cumulative incidence of each category was calculated by using the Kaplan-Meier method. Cox proportional hazards models were fit to estimate the risk ratios (case subjects versus control subjects) and corresponding 95% confidence intervals. RESULTS Subjects were followed to median ages of 18.2 (case subjects) and 18.7 (control subjects) years. Significant differences between autism case and control subjects were identified in the cumulative incidence of constipation (33.9% vs 17.6%) and feeding issues/food selectivity (24.5% vs 16.1). No significant associations were found between autism case status and overall incidence of gastrointestinal symptoms or any other gastrointestinal symptom category. CONCLUSIONS As constipation and feeding issues/food selectivity often have a behavioral etiology, data suggest that a neurobehavioral rather than a primary organic gastrointestinal etiology may account for the higher incidence of these gastrointestinal symptoms in children with autism.

Abstract
Asperger syndrome is a relatively new diagnostic classification. A number of factors make receiving a diagnosis of Asperger syndrome in adulthood a unique experience. This study used a phenomenological approach to examine the experiences of 10 adults receiving such a diagnosis. Results suggested that six major themes were associated with receiving a diagnosis of Asperger syndrome. Individuals discussed their negative life experiences and their experience of services prior to diagnosis, which led to individuals holding certain beliefs about the symptoms of Asperger syndrome. These beliefs had an effect on the formation of each individual's perceived self-identity. Participants made links between how they felt when they received the diagnosis and their current beliefs about both their `symptoms' and themselves. Finally, participants highlighted the importance of the societal view of Asperger syndrome. The implications of these findings are reappraised in the context of previous research and the wider literature on identity formation.

Abstract
The substantial increase in the prevalence of autism necessitates that practicing physicians become more familiar with the presentation of symptoms to improve early diagnoses and interventions, thus improving the prognosis for affected children. Autism is a complex neurodevelopmental disorder with a triad of core impairments in social interactions, repetitive behaviors, and communication. Clinically, autism appears as a spectrum, with many variations in the severity of defining behaviors and associated symptoms among children. Although the etiology of autism is unknown, it is thought to involve a genetic susceptibility that may be triggered by environmental factors. Because of the high variability in behaviors, biologic findings, and response to treatment, many specialists are assuming a theory of many different autisms, each of which may have a somewhat different etiology and response to treatment. Although there is no known cure for autism, many treatments are available to improve core and associated symptoms.
