Infantile autism: a total population study of reduced optimality in the pre-, peri-, and neonatal period

Area of Science:

• Neurodevelopmental disorders
• Pediatric neurology
• Autism spectrum disorder (ASD) research

Background:

• Early research suggested children with autism spectrum disorder (ASD) did not experience potential brain injury.
• Recent studies indicate a potential link between prenatal and perinatal factors and ASD development.
• Understanding these early-life factors is crucial for early intervention and prevention strategies.

Purpose of the Study:

• To investigate the occurrence of reduced optimality in the pre-, peri-, and neonatal periods in children diagnosed with infantile autism.
• To compare these findings with a matched control group to identify significant differences.
• To re-evaluate the relationship between early developmental factors and the etiology of autism.

Main Methods:

• A total population sample of 25 children with infantile autism was selected.
• A control group of 25 children, matched for sex and maternity clinic, was established.
• Medical records were retrospectively reviewed to assess reduced optimality in the prenatal, perinatal, and neonatal stages.

Main Results:

• Children with autism exhibited significantly higher scores for reduced optimality compared to the control group.
• Prenatal factors were particularly associated with increased reduced optimality in the autistic group.
• The findings indicate a notable prevalence of adverse early developmental factors in children with autism.

Conclusions:

• The study provides evidence contradicting earlier reports suggesting no link between early adverse events and autism.
• Prenatal and perinatal reduced optimality may play a significant role in the development of autism spectrum disorder.
• Further research is warranted to explore the causal pathways and implications for clinical practice.
