OBJECTIVES
Increasing numbers of young children referred for a differential diagnosis of autism spectrum disorders (ASD) necessitates better understanding of the early syndrome expression and the utility of the existing state-of-the art diagnostic methods in this population.
METHOD
Out of 31 infants under the age of 2 years referred for a differential diagnosis, 19 were diagnosed with autism, and 9 with pervasive developmental disorder - not otherwise specified (PDD-NOS) when reassessed at 3…

- 2008
Early detection of—and intervention to treat—ASD is crucial because it is likely to lead to an improved outcome, and early diagnosis will lead to earlier behavior-based intervention, which is associated with improvements in core areas, such as social functioning and communication.
Early diagnosis of autism spectrum disorder: stability and change in clinical diagnosis and symptom presentation.
- Psychology, MedicineJournal of child psychology and psychiatry, and allied disciplines

Stability was documented for children diagnosed at 19 months on average, although a minority of children initially showed unclear diagnostic presentations, and findings highlight utility of the ADOS-T in making early diagnoses and predicting follow-up diagnoses.

The rationale for defining a new disorder, Early Atypical Autism Spectrum Disorder (EA-ASD) to accompany ASD in the new revision of the ZERO to THREE Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC:0-5) (in press) alternative diagnostic classification manual is outlined.
Early assessment and diagnosis of children

This chapter will review the evidence for ASD, the epidemiology and prevalence of these disorders and consider (using the framework of the National Autism Plan for Children) a range of assessment and diagnostic procedures including the use of the best estimate clinical diagnosis for clinical and research practice.
Overall prognosis of preschool autism spectrum disorder diagnoses.
- Psychology, MedicineThe Cochrane database of systematic reviews
- 2022
The majority (95% confidence interval 89% to 95%) of participants continued to meet diagnostic criteria for autism spectrum disorder from baseline to follow-up one or more years later; however, the quality of the evidence was judged as low due to study limitations and inconsistency.
Early markers of autism spectrum disorders in infants and toddlers prospectively identified in the Social Attention and Communication Study
- Psychology, MedicineAutism : the international journal of research and practice
- 2013
The recurring key markers of both autistic disorder and autism spectrum disorder were deficits in eye contact and pointing, and from 18 months, deficits in showing became an important marker and were found to be the best group of predictors for a best estimate diagnostic classification of autistic disorder/autism spectrum disorder at 24 months.

A review of the current state of the science on early identification, screening, and intervention of ASD was warranted because of advances in genetic, neuroimaging, and other neurobiological research.

A comprehensive review of findings from recent studies on the early development of children with autism spectrum disorders is provided, summarizing current knowledge on early signs of autism Spectrum disorders, the screening properties of early detection tools, and current best practice for diagnostic assessment before 2 years of age.
Diagnostic tests for autism spectrum disorder (ASD) in preschool children.

This Review evaluated diagnostic tests in terms of sensitivity and specificity to determine whether any diagnostic test has greater diagnostic test accuracy for age-specific subgroups within the preschool age range.
A prospective study of toddlers with ASD: short-term diagnostic and cognitive outcomes.
- Psychology, MedicineJournal of child psychology and psychiatry, and allied disciplines

Stability of ASD diagnosis in toddlers is high, though marked changes in severity of symptoms is to be expected in a minority of cases and particular relevance of the assessment of verbal and nonverbal communication skills to diagnostic differentiation between subtypes within ASD in the second year of life is suggested.
