Introduction: The prevalence of Autism Spectrum Disorder (ASD) is four times higher in males than females; however, females are significantly more likely to go undiagnosed due to the existence of a “female autistic phenotype”, a manifestation unique to females that conflicts with conventional, masculine conceptualizations of ASD. Furthermore, subthreshold autistic traits, which exert a significantly negative impact on quality of life and represent a vulnerability factor for the development of other psychopathological conditions, may remain even more under-recognized. Subsequently, many women with ASD may never receive a diagnosis or any resulting care, with serious consequences for their health. Aims: We aimed to describe two brief cases in order to confirm the diagnostic difficulties that ASD female undergo during their clinical evaluation and the possible alternative phenotype that they can manifest. Methods: We reported the cases of two young women on the autism spectrum that came to clinical attention only after the development of severe symptomatology attributed to other mental disorders, overlooking the presence of underlying autism spectrum features and a brief résumé of the literature on this topic. Results: These cases confirm the need for a timely and proper identification of females on the autism spectrum in order to prevent complications and improve the outcome. Conclusions: Research on gender differences could lead to a reexamination of the sex ratio in the prevalence of ASD and provide a better understanding of several psychiatric conditions that are frequently diagnosed in women, supporting the neurodevelopmental approach to psychopathology.

Objective: Orthorexia nervosa (ON) is characterized by the pursuit of extreme dietary purity due to an exaggerated focus on food quality that could ultimately lead to a new kind of eating disorder. Even though researchers have tried to reach a univocal description of ON, to this date, there is no consensus on its diagnostic criteria, making it considerably more difficult to develop a valid questionnaire for assessing the symptoms of ON and to assess its actual prevalence. The aim of this review was to evaluate and gather scientific evidence about the prevalence of ON in both clinical and non-clinical adult populations, using the main validated scale for ON evaluation.Methods: Electronic databases (PubMed, Scopus, and Web of Science) were reviewed to identify studies in accordance with PRISMA guidelines; at the end of the selection process, 62 studies were included.Results: Prevalence rates of ON vary greatly due to the differences in psychometric qualities of the tools used and the socio-cultural norms of the countries, with the lowest being obtained with the Dusseldorf orthorexic scale (DOS) (2.6% up to 36.7% in cancer survivor women) and the BOS-T (12.8% up to 34.7%), the greatest variability concerning the two thresholds of the ORTO-15 (14.6% with the >35 threshold and up to 86% with the >40 threshold) and the higher score being reported with the ORTO-11 in post-partum women (87.7%).Conclusions: Additional research is necessary to support the development of a thorough, sensitive, and valid questionnaire for assessing the symptoms of ON.

The current literature globally highlights the efficacy of Clozapine in several psychiatric disorders all over the world, with an FDA indication for reducing the risk of repeated suicidal behavior in patients with schizophrenia or schizoaffective disorder. A growing field of research is also stressing a possible broader beneficial effect of Clozapine in promoting neuroprotection and neurotrophism. However, this drug is linked to several life-threatening side effects, such as agranulocytosis, myocarditis and seizures, that limit its use in daily clinical practice. For this work, a search was performed on PubMed using the terms “Clozapine indications”, “Clozapine adverse effects”, “Clozapine regenerative effects”, and “Clozapine neuroplasticity” with the aim of reviewing the scientific literature on Clozapine’s treatment indications, adverse effects and potential regenerative role. The results confirmed the efficacy of clozapine in clinical practice, although limited by its adverse effects. It appears crucial to raise awareness among clinicians about the potential benefits of using Clozapine, as well educating medical personnel about its risks and the early identification of possible adverse effects and their management.

Background: In recent years, there has been growing interest in the evaluation of autism spectrum disorder (ASD) and autistic traits in prison populations and offenders. Due to misleading headlines and highly publicized criminal cases, the belief that autistic individuals are more prone to commit crimes has spread among the general population, also leading to increasing research on this matter. Aims: In this context, this narrative review aimed to analyze the available scientific literature on the bi-directional link between ASD and criminal behaviors and to assess the key characteristics of eventual ASD offenders, including sociodemographic data, comorbidities, crime-related features, and interactions with the criminal justice system. Results: Our review highlighted that the available studies lack methodological rigor and present controversial results. Overall, the current state of research does not support any definitive correlation between ASD or autistic traits and the predisposition to engage in criminal conduct. Further studies are needed to confirm or reject this hypothesis.

Background/Objectives: Recent research has explored the presence of subthreshold autistic traits (ATs) in individuals with borderline personality disorder (BPD), suggesting that these traits may contribute to the severity of BPD symptoms and increase the risk of other mental health issues, including suicidal behaviors. This study aims to investigate the relationship between ATs and affective symptoms, such as mood instability and suicidality, in people diagnosed with BPD. Methods: A total of 48 subjects with BPD were assessed with self-report questionnaires including the Adult Autism Subthreshold Spectrum (AdAS Spectrum), the mood spectrum self-report version (MOODS-SR) and the ruminative response scale (RRS). Results: Subjects with significant ATs scored higher than BPD subjects in all domains and in the total score of AdAS Spectrum, RRS, and MOODS-SR, as well as in the items investigating suicidality. RRS total score, its depression domain, and the MOODS-SR rhythmicity domain, as well as suicidality, were predictors of the presence of ATs. Conclusions: Our data confirm the relationship between the presence of clinically significant ATs and affective symptoms, ruminative thinking, and suicidality in patients with BPD.

Background/Objectives: Recent lifestyle and dietary changes, driven by health awareness and ecological concerns, have led to the rise in numerous type of diets, which can promote well-being but may also contribute to Orthorexia Nervosa (ON), which have been suggested to be linked to autism spectrum disorder. This study aimed to explore the relationship between autistic traits, social camouflaging, and orthorexic tendencies in female university students, focusing on how these factors intersect with specific dietary habits. Methods: 554 female students were recruited via an online survey and assessed with the Adult Autism Subthreshold (AdAS) Spectrum, the Camouflaging Autistic Traits Questionnaire (CAT-Q), and the ORTO-R. Participants were categorized into four groups based on AdAS Spectrum and CAT-Q quartiles. Results: Vegans and vegetarians exhibited higher orthorexic tendencies and specific autistic traits. High scorers on the AdAS Spectrum and CAT-Q also showed higher ORTO-R scores, with both AdAS Spectrum and CAT-Q total scores, as well as certain domains, serving as significant positive predictors of higher ORTO-R scores. Notably, the AdAS Spectrum total score had a significant direct and indirect effect (through the CAT-Q) on the ORTO-R total score. Conclusions: The study found significant associations between autistic traits, social camouflaging behaviors, and orthorexic tendencies in female university students. These findings suggest that the strict dietary behaviors and rigid thinking characteristic of orthorexia may be influenced by underlying autistic features, highlighting the need for further research into the intersection of autism and eating disorders.
