What Are the Main Diagnostic Guidelines for Autism in ICD-11? 

The ICD-11 autism diagnostic guidelines provide clear criteria for diagnosing autism spectrum disorder (ASD) based on the latest scientific understanding of the condition. These guidelines emphasise the need for a comprehensive assessment that takes into account the core characteristics of autism, including social communication challenges and restricted, repetitive behaviours. The ICD-11 guidelines aim to ensure that diagnoses are consistent, evidence-based, and applicable across different healthcare systems globally. 

Key Components of the ICD-11 Autism Diagnostic Guidelines 

Here are the primary elements of the ICD-11 autism diagnostic guidelines: 

Autism Traits 

The ICD-11 highlights that individuals with ASD exhibit persistent deficits in social communication and interaction across multiple contexts. This includes difficulties in verbal and non-verbal communication, such as understanding social cues and establishing relationships with peers. Additionally, the ICD-11 guidelines specify that there must be restricted, repetitive patterns of behaviour, interests, or activities, such as engaging in specific routines or fixating on objects. 

Diagnosis Procedure 

 The diagnosis procedure in ICD-11 includes a detailed evaluation of developmental history, current symptoms, and behaviour patterns. This may involve structured interviews with caregivers, observation of the child’s behaviour, and assessments such as the ADOS-2 or ADI-R to confirm the presence of autism-related traits. The guidelines stress that the symptoms should appear early in development and cause significant impairment in social or occupational functioning. 

Criteria for Severity Levels 

ICD-11 autism diagnostic guidelines also provide criteria for determining the severity of autism, considering the level of support required by the individual. This includes whether the person requires substantial support, which is common in individuals with more severe forms of autism, or if they can function independently with minimal assistance.
