  • Required support
  • Required substantial support
  • Required very substantial support

Age of diagnosis: symptoms must present within neurodevelopmental age. Symptoms are recognized during 12-24 months of age. but may be seen earlier as well


  • Autism is a degenerative disorder
  • Without therapy one can manage symptoms


Autism as a different ability


One of the epidemics among all neurodevelopmental disorders is Autism spectrum disorder. 1 in 68 children has been diagnosed with autism and the number is increasing day by day. Considering this epidemic, the question that arises now a day is that whether the number is really increasing or it’s just that the psychiatrist/ psychologist is sensitive enough to diagnose it at a quicker ratio.
