Review
Autism spectrum disorder is made up of several disorders, which include autism, Asperger syndrome, and pervasive developmental disorder. Boys are four times more likely to be diagnosed than girls with autism spectrum disorder, and symptoms usually become apparent by the age of three. Autism spectrum disorders' core characteristic features are abnormal interaction, impairment in communication, and stereotyped behaviors with restricted activities and interests. There are also non-core features associated with autism spectrum disorder, and these are aggression, self-injurious behavior, and tantrums. To date, there is no one drug approved to treat the core symptoms of autism spectrum disorder, but antipsychotic drugs such as risperidone have been shown to be effective at treating both core and non-core symptoms in controlled trials using multiple behavioral rating scales such as the Aberrant Behavioral Checklist subscale, the Clinical Global Impression Improvement Scale, the Ritvo-Freeman Real Life Scale, the Children's Yale-Brown Obsessive Compulsive Scale, the Vineland Adaptive Behavior Scale, and the Social Withdrawal Subscale. The safety, efficacy, acceptability, and tolerability of risperidone were assessed in these studies, and weight gain was a common side effect observed, but the outcome was usually mild and self-limiting. The effect of risperidone on cognition was explored in this article. The studies selected for this article were of small sample size and short duration, which presented limitations for treatment with risperidone and an area that needs to be explored further for its contribution to clinical practice.

Subjects with Asperger's syndrome without intellectual disabilities have significant difficulties in establishing social relationships despite their IQ being within the normal range. One of the effects of social deficit is depression. The question arises whether loneliness and dimensions of meaning in life correlate with the severity of depression and whether the average severity of depression, loneliness and dimensions of meaning in life differentiate the following groups: people with Asperger's syndrome and depression, people with Asperger's syndrome without depression, people with depression without Asperger's syndrome and healthy subjects. The study was conducted on a total of 170 people, including: 43 people with Asperger's syndrome and depression, 41 people with Asperger's syndrome without depression, 40 people with depression without Asperger's syndrome and 46 healthy people (without Asperger's syndrome and without depression). All were administered a demographic survey, Beck Depression Inventory II (BDI-II), De Jong Gierveld Loneliness Scale, Life Attitude Profile-Revised. Asperger's syndrome and depressive episodes were diagnosed on the basis of ICD-10 research criteria still applicable in Poland. In the group with Asperger's syndrome and depression the highest levels of loneliness and the lowest values of the dimensions of the sense of meaning in life, except for the acceptance of death, were observed. This result was significantly different from the results obtained in the other study groups. Both in people with Asperger's syndrome without depression and in people with depression without Asperger's syndrome, the values of the dimensions of the sense of meaning in life and the level of loneliness differ significantly from the results obtained in the control group. The BDI-II scores correlated positively with the loneliness values and negatively with the sense of meaning in life values in all groups. The results indicate that both suffering from depression and having Asperger's syndrome are associated with an increased sense of loneliness and a reduced sense of meaning in life. People with Asperger's syndrome and depression have the highest values of loneliness and the lowest values of dimensions of the sense of meaning of life compared to the other groups studied. The limitation of the work is the deliberate selection of groups, because it would be interesting to answer the question whether Asperger's syndrome is a risk factor for depression in the population.

Functional contribution of the intestinal microbiome in autism spectrum disorder, attention deficit hyperactivity disorder, and Rett syndrome: a systematic review of pediatric and adult studies.
INTRODUCTION
Critical phases of neurodevelopment and gut microbiota diversification occur in early life and both processes are impacted by genetic and environmental factors. Recent studies have shown the presence of gut microbiota alterations in neurodevelopmental disorders. Here we performed a systematic review of alterations of the intestinal microbiota composition and function in pediatric and adult patients affected by autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and Rett syndrome (RETT).
METHODS
We searched selected keywords in the online databases of PubMed, Cochrane, and OVID (January 1980 to December 2021) with secondary review of references of eligible articles. Two reviewers independently performed critical appraisals on the included articles using the Critical Appraisal Skills Program for each study design.
RESULTS
Our systematic review identified 18, 7, and 3 original articles describing intestinal microbiota profiles in ASD, ADHD, and RETT, respectively. Decreased Firmicutes and increased Bacteroidetes were observed in the gut microbiota of individuals affected by ASD and ADHD. Proinflammatory cytokines, short-chain fatty acids and neurotransmitter levels were altered in ASD and RETT. Constipation and visceral pain were related to changes in the gut microbiota in patients affected by ASD and RETT. Hyperactivity and impulsivity were negatively correlated with (phylum Firmicutes) and positively correlated with sp. (phylum Bacteroidetes) in ADHD subjects. Five studies explored microbiota-or diet-targeted interventions in ASD and ADHD. Probiotic treatments with sp. and fecal microbiota transplantation from healthy donors reduced constipation and ameliorated ASD symptoms in affected children. Perinatal administration of sp. prevented the onset of Asperger and ADHD symptoms in adolescence. Micronutrient supplementation improved disease symptomatology in ADHD without causing significant changes in microbiota communities' composition.
DISCUSSION
Several discrepancies were found among the included studies, primarily due to sample size, variations in dietary practices, and a high prevalence of functional gastrointestinal symptoms. Further studies employing longitudinal study designs, larger sample sizes and multi-omics technologies are warranted to identify the functional contribution of the intestinal microbiota in developmental trajectories of the human brain and neurobehavior.

Review
In the last decades, growing caseness for Autism Spectrum Disorder (ASD) has been observed, owing to the diagnostic accretion of low-impairment forms, over and above other possible causes. Unrecognized ASD is likely to be mislabeled as a psychotic disorder (PD), as people in the spectrum may show 'pseudopsychotic' symptoms, resembling both negative and positive symptoms. On the other hand, PDs are likely to be overlooked when they arise in people with ASD, due to the 'diagnostic overshadowing' of new-onset conditions by lifelong core autistic symptoms. The three available metanalyses on the occurrence of psychosis in adults with ASD convergently reported a rate of PDs that is at least ten times higher than in the general population. Therefore, the lack of literature addressing risk factors, outcomes, and treatment options for psychosis in the context of ASD is utterly concerning. The present review aims to summarize up-to-date knowledge of PDs with comorbid ASD in terms of clinical features, course, and treatment.

Review
Being a typically developing sibling to a child with autism spectrum disorder (ASD-Sib) can be associated with several behavioral and mental health problems. With this understanding, researchers are beginning to focus on sibling-oriented interventions. This review seeks to evaluate the current literature on such interventions. We searched digital databases and identified eight relevant studies. The sample (n = 247) had an age range of 4-16 years. The outcomes were generally positive, with improvements in different facets of ASD-Sibs. Results differed due to varied intervention styles, outcome variables, methods, and samples. Our findings highlight the potential for improvement in ASD-Sib's knowledge of autism and their psychological functioning and hence call for further research with robust methods.

INTRODUCTION
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that persists into adulthood with both social and cognitive disturbances. Asperger's syndrome (AS) was a distinguished subcategory of autism in the DSM-IV-TR defined by specific symptoms including difficulties in social interactions, inflexible thinking patterns, and repetitive behaviour without any delay in language or cognitive development. Studying the functional brain organization of individuals with these specific symptoms may help to better understand Autism spectrum symptoms.
METHODS
The aim of this study is therefore to investigate functional connectivity as well as functional network organization characteristics using graph-theory measures of the whole brain in male adults with AS compared to healthy controls (HC) (AS: = 15, age range 21-55 (mean ± sd: 39.5 ± 11.6), HC: = 15, age range 22-57 [mean ± sd: 33.5 ± 8.5]).
RESULTS
No significant differences were found when comparing the region-by-region connectivity at the whole-brain level between the AS group and HC. However, measures of "transitivity," which reflect local information processing and functional segregation, and "assortativity," indicating network resilience, were reduced in the AS group compared to HC. On the other hand, global efficiency, which represents the overall effectiveness and speed of information transfer across the entire brain network, was increased in the AS group.
DISCUSSION
Our findings suggest that individuals with AS may have alterations in the organization and functioning of brain networks, which could contribute to the distinctive cognitive and behavioural features associated with this condition. We suggest further research to explore the association between these altered functional patterns in brain networks and specific behavioral traits observed in individuals with AS, which could provide valuable insights into the underlying mechanisms of its symptomatology.

BACKGROUND
Asperger syndrome is a type of autism spectrum disorder that may affect oral health and dental management. Spongiotic gingival hyperplasia is a rare lesion with unique clinicopathological features and unknown pathogenesis that has not been previously reported in a patient with autism spectrum disorder. The purpose of this case report is to present the first case of spongiotic gingival hyperplasia in a child with Asperger syndrome.
METHODS
A 14-year-old boy with Asperger syndrome was referred for diagnosis and management of bright red granular overgrowths of the marginal gingiva and interdental papilla of the mandibular right incisors and marginal gingiva of the mandibular left incisor. A biopsy was performed on the interdental papilla between the mandibular right incisors.
RESULTS
Microscopic examination and cytokeratin 19 immunopositivity confirmed the diagnosis of spongiotic gingival hyperplasia. The parents of the patient declined any further intervention, and four months later the gingival lesions, including the biopsied area, did not show any significant difference from the initial examination.
CONCLUSIONS
Patients with autism spectrum diseases, such as Asperger syndrome, cannot achieve a good level of oral hygiene. Thus, it is expected that the incidence of spongiotic gingival hyperplasia should be higher in this group of patients, in case oral microbiome participates in its pathogenesis. Management of such lesions is challenging, as such patients do not comply with a proper oral hygiene program and do not cooperate with surgical excision.

We developed a 28-item Chinese Eyes Test and tested its psychometric properties with a mixed sample of high-functioning adults with autism or Asperger syndrome and neurotypical adults. The Chinese Eyes Test showed good convergent and divergent validity, satisfactory known-group discrimination, and acceptable internal consistency. The identified cutoff score of 18 or below (Sensitivity: 66.7%; Specificity: 84.0%) should be useful for identifying clinically significant levels of social cognitive deficits, in terms of difficulty with the perceptual understanding of others' mental states, in high-functioning adults with autism or Asperger syndrome.

In this article, we present the case of an adult patient, whose main problem is episodes of fantasizing and rocking lasting up to 12 hours a day and completely preventing school development. The nature of the disorder in the patient is related to the sinking into fantasies, and not typical obsessions as in OCD. The patient was previously treated with drugs from the SSRI group, neuroleptics (without aripiprazole) and methylphenidate. Only methylphenidate showed some improvement; however, it made the patient feel ‟stiff in thinking". The patient was hospitalized because of a suicide attempt, which, as it later turned out, was self-harm with no intention of killing himself. During hospitalization, a differential diagnosis was performed and the diagnosis of Asperger's syndrome was made, which was accompanied by immersion in the world of one's fantasies and stereotypical behavior. The patient was administered aripiprazole at a dose of 15 mg/d and after three weeks, a significant improvement in health was achieved, including a reduction in the duration of episodes from several hours to several dozen seconds. The drug is well tolerated by the patient. The patient was discharged from the hospital and continues his school education. In the article, we present single case reports in which similar spectacular results were achieved in similar cases. We also describe a possible physiological explanation for this response to this drug.
