Headline : AIIMS doctors develop application to help in timely diagnosis of autism
- In the backdrop of the World Autism Awareness Day, doctors at AIIMS have developed a mobile app for early diagnosis of Autism Spectrum Disorders.
- World Autism Awareness Day is observed on April 2 every year.
About the App
- The app developed is called PedNeuroAiimsDiagnostics.
- It is a questionnaire-based app which has 2 sections of questionnaire
- Section A has questions to assess the social interaction and communication skills
- Section B has questions to analyse the response given to questions in section A.
- Based on the response to the questionnaire the app analyses if the child has any of the Autism Spectrum Disorders
- Accordingly the following cases are considered to be suffering with ASD
- A child who cannot babble or point or gesture by 12 months
- Couldn’t say single word by 16 months
- Couldn’t say any two-word spontaneous phrases by 24 months
- Loss of language or social skills at any age.
- The App is easy to use with even a paediatrician can assess the test results.
- The app is very sensitive in that detects 98% of cases.
- It is also very specific in that it predicts specifically which of the ASD in 92% of the cases.
In focus: Autism Spectrum Disorders

- It shows signs in the first 3 years of child development.
- Autism is a brain malfunction mainly associated with impairments in 3 main areas
