Objective: To highlight the differences in behaviors in children with diagnosis of Down syndrome.
Method: Eight children with Down syndrome who displayed autistic features were compared with eight Down syndrome children without autistic features. These children were randomly selected and were matched for age and level of retardation. Standardized Psychological tests were administered to tap the behavioral differences. Mann-Whitney U test was used for significance of difference between both the groups.
Results: Down syndrome children without Autism Spectrum Disorder had better communication and socialization skills than children with Down syndrome with Autism Spectrum Disorder. Down syndrome children with Autism Spectrum Disorder displayed more restricted repetitive and stereotyped patterns of behaviors, interests and activities.
Conclusion: Our findings indicate that Autism Spectrum Disorder manifests as a distinct behavioral phenomenon in Down syndrome. Hence it is important for professionals to consider the possibility of a dual diagnosis which will entitle the child to a more specialized and effective educational and intervention services.

Background: The causal relationship between PM (particulate matter with an aerodynamic diameter ≤2.5 μm) and common mental disorders, along with its neuropathological mechanisms, remains unclear.
Methods: We used genome-wide association study datasets from the UK Biobank and Psychiatric Genomics Consortium to systematically investigate the causal relationship between PM and nine common psychiatric disorders using two-sample Mendelian randomization (TSMR) methods.

Echolalia, the immediate or delayed repetition of speech, is a core diagnostic criterion for autism spectrum disorder. It has been studied for over 50 years and is well-described; however, no consensus on prevalence estimates exists for echolalia's occurrence in autistic youth. The current study sought to (1) describe endorsement of echolalia-related items using parent-, teacher-, and clinician-reports in a well-validated sample of autistic youth and (2) characterize relations between echolalia and other key factors, including age, language ability, and repetitive behaviors.

Emerging research has highlighted the significant role of microbiota-gut-brain communication in child psychiatric disorders, including autism spectrum disorder (ASD) and anxiety disorders. Despite this, mainstream psychiatric interventions for children continue to focus predominantly on neurological and psychological therapies, neglecting the critical influence of gut microbiota on brain development and behavior. This commentary underscores the need for greater integration of microbiota-targeted therapies, such as dietary interventions, prebiotics, and probiotics, into early psychiatric intervention strategies.

Introduction: Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by deficits in social interaction and communication, along with restricted and repetitive behaviors. Both genetic and environmental factors contribute to ASD, with prenatal exposure to valproic acid (VPA) and nicotine being linked to increased risk. Impaired adult hippocampal neurogenesis, particularly in the ventral region, is thought to play a role in the social deficits observed in ASD.

Introduction: Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition diagnosed clinically based on phenotypic characteristics and criteria such as the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Due to its significant social, emotional, and psychological impacts, early identification and diagnosis are crucial for starting early intervention and improving outcomes. A screening tool is imperative in identifying young children at risk so timely intervention can be instituted.
