Review
Autism Spectrum Disorder (ASD) refers to a group of neurodevelopmental disorders including autism, Asperger's syndrome (AS) and pervasive developmental disorder-not otherwise specified (PDD-NOS). The new diagnostic criteria of ASD focuses on two core domains: social communication impairment and restricted interests/repetitive behaviors. The prevalence of ASD has been steadily increasing over the past two decades, with current estimates reaching up to 1 in 36 children. Hereditary factors, parental history of psychiatric disorders, pre-term births, and fetal exposure to psychotropic drugs or insecticides have all been linked to higher risk of ASD. Several scales such as the Childhood Autism Rating Scale (CARS), The Autism Spectrum Disorder-Observation for Children (ASD-OC), The Developmental, Dimensional, and Diagnostic Interview (3di), are available to aid in better assessing the behaviors and symptoms associated with ASD. Nearly 75% of ASD patients suffer from comorbid psychiatric illnesses or conditions, which may include attention-deficit hyperactivity disorder (ADHD), anxiety, bipolar disorder, depression, Tourette syndrome, and others. Both pharmacological and non-pharmacological interventions are available for ASD. Pharmacological treatments include psychostimulants, atypical antipsychotics, antidepressants, and alpha-2 adrenergic receptor agonists. These medications provide partial symptomatic relief of core symptoms of ASD or manage the symptoms of comorbid conditions. Non-pharmacological interventions, which show promising evidence in improving social interaction and verbal communication of ASD patients, include music therapy, cognitive behavioral therapy and social behavioral therapy. Hormonal therapies with oxytocyin or vasopressin receptor antagonists have also shown some promise in improving core ASD symptoms. The use of vitamins, herbal remedies and nutritional supplements in conjunction with pharmacological and behavioral treatment appear to have some effect in symptomatic improvement in ASD, though additional studies are needed to confirm these benefits. Developing novel disease-modifying therapies may prove to be the ultimate intervention for sustained improvement of symptoms in ASD.

Review
Autism spectrum disorder is characterized by difficulty with social communication and restricted, repetitive patterns of behavior, interest, or activities. The Diagnostic and Statistical Manual of Mental Disorders, 5th ed., created an umbrella diagnosis that includes several previously separate conditions: autistic disorder, Asperger syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified. There is insufficient evidence to recommend screening for autism spectrum disorder in children 18 to 30 months of age in whom the disorder is not suspected; however, there is a growing body of evidence that early intensive behavioral intervention based on applied behavior analysis improves cognitive ability, language, and adaptive skills. Therefore, early identification of autism spectrum disorder is important, and experts recommend the use of a validated screening tool at 18- and 24-month well-child visits. Medications can be used as adjunctive treatment for maladaptive behaviors and comorbid psychiatric conditions, but there is no single medical therapy that is effective for all symptoms of autism spectrum disorder. Prognosis is heavily affected by the severity of diagnosis and the presence of intellectual disability. Children with optimal outcomes receive earlier, more intensive behavioral interventions and less pharmacologic treatment.

Review
Asperger's syndrome is a neurodevelopmental disorder which is part of the large family of autism spectrum disorders. People with Asperger's syndrome have difficulties in social interactions, verbal and non-verbal communication, and may display behavioural oddities, with stereotypies and limited interests. They show no language delay and their cognitive development is not marked by an overall delay but by specific impairments in certain areas such as the executive functions. The clinical presentations are very heterogeneous, varying according to age and psychiatric comorbidities. Screening, diagnosis and specialized treatment are not made any easier by the diversity of the clinical manifestations. Asperger's syndrome is often diagnosed belatedly, at 11years of age on average and even in adulthood in some cases. This late diagnosis has a significant impact on the risks of depression and a poor quality of life. However, in adulthood or in adolescence, certain situations, personality traits and cognitive profiles or certain comorbidities should suggest the hypothesis of an Asperger-type autism spectrum disorder. We propose here a review of the clinical situations at different ages of life that could help with the screening and the referral of patients to specialized clinicians for diagnosis and appropriate treatment.

Review
Autism spectrum disorder (ASD) was described for the first time in 1943 by Leo Kanner, and since 2004, 18 490 articles in the subject have been published, which in turn have been cited 48 416 times.1 Almost half of these publications come from the United States of America and the vast maority of the efforts to improve the quality of life of these patients have taken place in developed countries. This disorder consists of an inability to acquire social and emotional skills during early development that progressively results in variable degrees of social adaptation discapacity. The etiology is multifactorial and includes functional and structural neurological abnormalities, some of them with putative genetic and/or epigenetic origin. There is an alarming lack of knowledge in the subject among health care professionals. The purpose of this systematic review is to summarize the most relevant historical, diagnostic and therapeutic aspects of ASD.

Comparative Study
Since Hans Asperger's first description (Arch Psych Nervenkrankh 117:76-136, 1944), through Lorna Wing's translation and definition (Psychol Med 11:115-129, 1981), to its introduction in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM, 1994), Asperger Syndrome has always aroused huge interest and debate, until vanishing in the DSM fifth edition (2013). The debate regarded its diagnostic validity and its differentiation from high functioning autism (HFA). The present study aimed to examine whether AS differed from HFA in clinical profiles and to analyze the impact of DSM-5's innovation. Differences in cognitive, language, school functioning and comorbidities, were revealed when 80 AS and 70 HFA patients (3-18 years) were compared. Results suggested that an AS empirical distinction within autism spectrum disorder should be clinically useful.

Review
A variant of autism spectrum disorder (ASD) known as Asperger syndrome (AS) is characterized by severe issues with interpersonal, verbal, and nonverbal communication as well as restricted and repetitive patterns of behavior and activities. Although there is no known cause for ASD, various genetic as well as non-genetic risk factors that may act either alone or in combination to induce ASD have been identified. The occurrence of ASD has been increasing worldwide. Co-occurring neuropsychological diseases are frequently present as well. The premise for diagnosis is the observation of abnormal conduct, with diagnostic criteria emphasizing limitations in social interaction and communication as well as constrained, repetitive behavioral patterns, activities, or hobbies. The degree of the illness and the presence of intellectual impairment have a significant impact on the prognosis. Like autism, Asperger's can neither be prevented nor treated. There is no specific medical therapy that can effectively cure all of the symptoms of autism. However, medications may be used as adjuvant therapy for maladaptive behaviors and co-occurring mental problems. The treatment aims to reduce core impairments, increase functional ability, and reduce harmful behaviors that could limit functional skills. It is crucial to provide proper care, establish supportive networks for individuals who are affected and their families, and use effective therapies to enhance functioning and results.

Review
Autism spectrum conditions comprise a set of early-onset neurodevelopmental syndromes with a prevalence of 1% across all ages. First diagnosis in adulthood has finally become recognised as an important clinical issue due to the increasing awareness of autism, broadening of diagnostic criteria, and the introduction of the spectrum concept. Thus, the idea of a lost generation of people who were previously excluded from a diagnosis of classic autism has arisen. Making a first diagnosis of autism spectrum conditions in adults can be challenging for practical reasons (eg, no person to provide a developmental history), developmental reasons (eg, the acquisition of learnt or camouflaging strategies), and clinical reasons (eg, high frequency of co-occurring disorders). The diagnostic process includes referral, screening, interviews with informants and patients, and functional assessments. In delineating differential diagnoses, true comorbidities, and overlapping behaviour with other psychiatric diagnoses, particular attention should be paid to anxiety, depression, obsessive-compulsive disorder, psychosis, personality disorders, and other neurodevelopmental disorders. Possible misdiagnosis, especially in women, should be explored. The creation of supportive, accepting, and autism-friendly social and physical environments is important and requires a coordinated effort across agencies and needs support from government policies.

Review
BACKGROUND
Mind-body therapies are often used by people with autism spectrum disorders (ASD). However, there has been little examination into which types of mind-body therapies have been investigated for people with ASD and for what purposes. A systematic review was conducted to evaluate the existing evidence for mind-body therapies for people with ASD, particularly to determine the types of mind-body therapies used and the outcomes that are targeted.
METHODS
PubMed, PsychInfo, and Scopus were searched using terms for ASD and mind-body therapies. Sixteen studies were selected for review; these studies tested interventions using mindfulness, meditation, yoga, Nei Yang Gong, and acceptance commitment therapy. Most study outcomes targeted behavior, psychological symptoms, and quality of life for children and adults with ASD as well as their parents.
RESULTS
There was little overlap between studies on the types of mind-body therapies used and associated outcomes, and only three of the studies were randomized controlled trials. Most studies were small and uncontrolled. Some studies modified the mind-body therapies to increase accessibility for people with ASD.
CONCLUSION
The evidence for mind-body therapies for people with ASD is limited and would benefit from larger randomized controlled trials.

UNLABELLED
Autism spectrum disorder (ASD) is one the most disabling developmental disorders, imposing an extremely high economic burden. Obtaining as accurate prevalence estimates as possible is crucial to guide governments in planning policies for identification and intervention for individuals with ASD and their relatives. The precision of prevalence estimates can be heightened by summative analyses of the data collected around the world. To that end, we conducted a three-level mixed-effects meta-analysis. A systematic search of the Web of Science, PubMed, EMBASE, and PsycINFO databases from 2000 up to 13 July 2020 was performed, and reference lists of previous reviews and existing databases of prevalence studies were screened. Overall, 79 studies were included in the analysis of ASD and 59-in the analysis of previously existing relevant diagnoses: 30 for Autistic Disorder (AD), 15 for Asperger Syndrome (AS), and 14 for Atypical Autism (AA) and Pervasive Developmental Disorder - Not Otherwise Specified (PDD-NOS); these research reports covered the period from 1994 to 2019. Pooled prevalence estimates were 0.72% (95% CI = 0.61-0.85) for ASD, 0.25% (95% CI = 0.18-0.33) for AD, 0.13% (95% CI = 0.07-0.20) for AS, and 0.18% (95% CI = 0.10-0.28) for the combined group of AA and PDD-NOS. Estimates were higher (1) for the studies that used records-review surveillance rather than other designs; (2) in North America compared with other geographical regions; and (3) in high-income compared with lower-income countries. The highest prevalence estimates were registered in the USA. There was an increase in autism prevalence estimates over time. The prevalence was also significantly higher for children aged between 6 and 12 years compared to children under the age of 5 and over the age of 13 years.
