What is Autism?
- Autism Spectrum Disorder (ASD) is a neurodevelopmental condition affecting communication, social interaction, and behavior.
- It includes a range of symptoms from mild to severe; often visible in early childhood but sometimes diagnosed later.
- Classified by the WHO as a diverse set of conditions, not a single disorder.
Relevance : GS 2(Health ,Social Issues)
Is Autism on the Rise?
- Prevalence of autism has increased:
- 1 in 36 (2020) → 1 in 31 (2022) in the U.S. (CDC data).
- In India, an estimated 1 in 68 children are affected by autism. This translates to approximately 18 million individuals on the autism spectrum in the country.
- Reasons:
- Better recognition and broader diagnostic criteria.
- Increased awareness and access to healthcare.
- Mild cases now included in diagnosis which were earlier missed.
What Causes Autism?
- No single cause — it’s a complex interplay of genetics and environment.
- Genetic factors: High heritability (up to 91% in some studies – JAMA 2016).
- Environmental factors (limited evidence, still under research):
- Advanced parental age.
- Prenatal exposure to air pollution.
- Vaccines do NOT cause autism – the MMR vaccine link has been debunked.
Is Autism Preventable?
- Not fully preventable due to complex etiology.
- Primary prevention is difficult with current knowledge.
- Focus should be on:
- Secondary prevention – early detection and screening.
- Tertiary prevention – targeted intervention and support.
Misinformation Risks
- Claims linking vaccines to autism have caused:
- Reduced vaccination rates.
- Increased public health risk (measles outbreaks, etc.).
- Such narratives blame parents (especially mothers) and increase stigma.
What is the Need of the Hour in Autism Care?
Early Diagnosis
- Many children are still not diagnosed early, especially in rural and underserved areas.
- Early detection is crucial for effective intervention.
Accessible Interventions
- Need for individualised, evidence–basedtherapies (speech, behavioral, occupational).
- Tailored interventions based on each child’s needs.
Psycho-education for Families
- Families need support and realistic guidance, not false promises or shame.
Maternal and Child Health
- Greater focus on maternalmental and physicalhealth during pregnancy.
- Move beyond communicable diseases to include mental and neurodevelopmental health in prenatal care.
Awareness and Sensitisation
- Combat myths and stigma around ASD.
- Promote inclusion and rights-based approach for individuals with autism.
Research and Data
- Continued, rigorous research on genetic and environmental factors.
- Avoid politicised or oversimplified narratives (e.g. blaming toxins or single causes).
