The main objectives of this study were to profile the communication difficulties and environmental changes adopted by parents of children with ASD who did not have proper access to healthcare/rehab facilities during the pandemic in Indian scenario.

Material and methods:
In total, 51 parents of children with ASD in the age range of 3 to 10 years participated in this study. They were asked to fill in a questionnaire (Google form) that had 20 close ended questions on their children's prelinguistic skills, communication behaviors, behavioral aspects, and emotional variations before and during the pandemic.

Depending on the severity of the disorder, children had difficulty in several tasks such as comprehension of simple commands and expression of daily needs.

Conclusions:
Individuals with ASD are a significant population who may require special assistance during the pandemic and future public health crises.
