Review
Autism is a neurodevelopmental disorder characterized by deficits in social cognition and communication, restricted interests, and stereotyped behaviors. Frequently associated with sensory dysfunction, other neurodevelopmental disorders, neuropsychiatric disorders, epilepsy and/or sleep disorders. This condition will accompany people throughout their lives, which will generate various support and treatment needs. Although there are no drugs that modify the core symptoms of autism, various drugs have shown their usefulness in associated conditions. Atypical antipsychotics for hyperactivity, impulsivity, agitation, auto or heteroaggression crises. Serotonin reuptake inhibitors, to decrease anxiety, obsessive-compulsive symptoms, and irritability/agitation. Stimulants and atomoxetine used for hyperactivity, inattention, and impulsivity. Clonidine and guanfacine show some efficacy on hyperactivity and stereotyped behaviors. Buspirone has been used for restrictive behaviors and anxiety. There are drugs in the research phase such as oxytocin, vasopressin and even some developed for specific entities related to autism such as arbaclofen in Fragile X and Trofinetide that has just been approved for use in Rett syndrome. As specific entities and their pathophysiology are identified, it is likely that tailored treatments will be developed for each entity associated with autism..

Meta-Analysis
: Recent studies have shown the existence of a positive relationship between physical exercise, symptomatic improvement, and reduction of damage caused by comorbidities associated with autistic spectrum disorder (ASD) in children, adolescents, and adults. The aim of this systematic review with meta-analysis (SRM) was to estimate the effects of physical exercise (PE) on the stereotyped behaviors of children with a diagnosis of ASD in intervention studies. : The design followed the PRISMA guidelines and the TREND statement to assess the quality of information in each study. Nine non-randomized intervention trial studies with low, moderate, and vigorous physical exercise, with a duration varying from 8 to 48 weeks and a frequency of 3 times a week, were included in the SRM. The dependent variable episodes of stereotypical behaviors was analyzed in all studies and assessed as the number of episodes demonstrated by the child in pre- versus post-exercise intervention conditions. : The eight studies included a total 129 children (115 males and 14 females) with an average age of 8.93 ± 1.69 years. Children with ASD showed a reduction of 1.1 in the number of occurrences of stereotypical behaviors after intervention with physical exercise. : Evidence was found to support physical exercise as an effective tool in reducing the number of episodes of stereotypical behaviors in children diagnosed with ASD.

Autism is a neurodevelopmental disorder characterized by deficits in social cognition and communication, restricted interests, and stereotyped behaviors. It is often associated with sensory dysfunctions, other neurodevelopmental disorders, neuropsychiatric disorders, epilepsy and/or sleep disorders. This condition will accompany people throughout their lives, with variations in its evolution. In the last ten years, only 1% of all autism research focused on developing post-secondary education programs and training in adult health services. Taking into account this dichotomy of interests, we must think about the different stages of life, such as early intervention, school inclusion, bullying, associated mental and medical disorders, lack of group belonging, job opportunities and the aging. Only by becoming aware of each of them can we achieve a better quality of life for people with autism and their families.

Review
The need for high-throughput, precise, and meaningful methods for measuring behavior has been amplified by our recent successes in measuring and manipulating neural circuitry. The largest challenges associated with moving in this direction, however, are not technical but are instead conceptual: what numbers should one put on the movements an animal is performing (or not performing)? In this review, I will describe how theoretical and data analytical ideas are interfacing with recently-developed computational and experimental methodologies to answer these questions across a variety of contexts, length scales, and time scales. I will attempt to highlight commonalities between approaches and areas where further advances are necessary to place behavior on the same quantitative footing as other scientific fields.

Review
The way autism is represented in fictional media can impact people's views of autistic people. For example, representations may contribute to negative views of autistic people as being unusual or dangerous, or they may challenge stereotypes and instead highlight the strengths of autistic people. This work aimed to review previous research to understand how autistic people have been represented in fictional media (Part A). It also sought to understand whether viewing fictional portrayals of autism has an impact on people's knowledge of autism and attitudes towards autistic people (Part B). Of 14 studies that were included in Part A, several unhelpful and stereotypical portrayals of autism emerged. Positive portrayals were those that highlighted the strengths of autistic people and reflected nuance. There is a need for greater diversity in representation of autism in fictional media. For example, not all autistic people are white heterosexual males. Across the five studies included in Part B, there were no improvements in people's knowledge of autism after watching or reading a short segment from a fictional TV series or novel that depicts an autistic person. Although there was a significant improvement in people's attitudes towards autistic people, these findings do not provide a complete picture given the short length of the media exposure and small number of studies. Future studies should investigate how multiple exposures to the representation of autistic people in both fictional and non-fictional sources can affect people's understanding of autism. There is also a need to develop more accurate and respectful ways of measuring people's knowledge of, and attitudes towards, autism.

Autism is a neurobiologically based neurodevelopmental disorder with high prevalence and a clear predominance in males. It is characterized by deficits in social cognition and communication, restricted interests, and stereotyped behaviors, frequently associated with sensory dysfunction others neurodevelopmental conditions, neuropsychiatric disorders, epilepsy, and/or sleep disorders. This condition will accompany people throughout their lives, which will generate various support and treatment needs. People with autism often need to "fit in" and for this they use techniques such as camouflage, also called masking. This attitude has been observed in people with typical development and in people with autism in childhood, adolescence and adult life, although in autistic people this behavior is more intense and takes longer and with more frequency and intensity in autistic adult women. This could explain the underreporting of autism, the later diagnosis, the delay in the therapeutic approach, and the greater presence of anxiety and depression disorders related to the effort that "appearing normal" implies. Even though camouflage people appear to be "normal" and fit in perfectly, this is not an attitude that we should promote and, on the contrary, it is imperativeto work to improve the environment and the understanding of each person. In this paper we will analyze the clinical aspects, their relationship with age, sex, and ways of detecting it.

Review
We start from the evidence that confirms a greater vulnerability to anxiety in people with autism and to wonder to what extent the intolerance to the uncertainty mediates in that anxiety. In addition, the alterations of the predictive abilities in autism could explain the coherence between greater intolerance to uncertainty and some peculiarities inherent in autism such as patterns of restrictive and stereotyped behaviors, interests and activities, and particularities in the processing of sensory information. This information will allow us to develop interventions specifically focused on this construct for the prevention and improvement of anxiety symptoms in autism in cases that the severity of intolerance to uncertainty constitutes a significant risk factor.

Review
The field of primate behavior management has had only limited success in preventing and treating abnormal behaviors, such as stereotypy and self-injury, in captive non-human primates (NHP). In contrast, applied behavior analysts have had great success in treating similar topographies of behavior in human clinical settings. By adapting and adopting the behavioral principles and methodologies commonly used by applied behavior analysts, primatologists may be able to develop more effective ways to analyze, reduce, and prevent these aberrant behaviors in NHP. This article reviews studies that have used behavior analytic techniques to successfully address problem behaviors in NHP. Additionally, relevant literature from the field of applied behavior analysis is reviewed to illustrate how adopting a theoretical framework that emphasizes the determination of the underlying operant functions of behavior could lead to new behavioral technologies and advance the field of captive primate management.

Review
In order to understand the physiological role of the caudate nucleus, we combine here our laboratory data on cats with reports of patients with selective damage to this nucleus. Cats with bilateral removal of the caudate nuclei showed a stereotyped behavior consisting of persistently approaching and then following a person, another cat, or any object, and attempting to contact the target. Simultaneously, the animals exhibited a friendly disposition and persistent docility together with purring and forelimbs treading/kneading. The magnitude and duration of this behavior was proportional to the extent of the removal reaching a maximum after ablations of 65% or more of the caudate tissue. These cats were hyperactive but they had lost the feline elegance of movements. Additional features of acaudate cats were: (1) postural and accuracy deficits (plus perseveration) in paw usage tasks including bar pressing for food reward; (2) cognitive and perceptual impairments on a T-maze battery of tasks and on the bar pressing tasks; (3) blockage or blunting of the species-specific behavioral response to a single injection of morphine; Unilateral caudate nucleus removal did not produce global behavioral effects, but only deficit in the contralateral paw contact placing reaction and paw usage/bar pressing. Moreover and surprisingly, we found hypertrophy of the ipsilateral caudate nucleus following prenatal focal neocortical removal. The findings in human were also behavioral (not neurological) and also occurred with unilateral caudate damage. The main manifestations consisted of loss of drive (apathy), obsessive-compulsive behavior, cognitive deficits, stimulus-bound perseverative behavior, and hyperactivity. Based on all of the above data we propose that the specific function of the caudate nucleus is to control approach-attachment behavior, ranging from plain approach to a target, to romantic love. This putative function would account well for the caudate involvement in the pathophysiology of a number of clinical syndromes that we mention, all of which compromise approach-attachment- affect behaviors. In addition we conclude that the caudate nucleus contributes importantly to body and limbs posture as well as to the accuracy and speed of directed movements.
