###Human: How to find out if my son is suffering from any communication problem? ###Assistant: Hi. I have gone through the query with keen interest and understand your concerns. Before making any opinions I need to inform you that take the things in objective manner and not on emotions I understand there is history of autism in the family and it does not mean your child suffers with autism. In a normal growing child there are many ups and downs and not responding on some occasions is not indicative of serious pathology like autism. We need to take notice that a child plays well with another child, responds to language on most occasions, cheerful, not having any abnormal repetitive stereotyped movements and communicates with the mother. Having said this I feel it will be appropriate to fill a simple questionnaire called Autism Spectrum Screening Questionnaire (ASSQ). This is a screening instrument for autism and you will know probably with sure that whether there is problem or not. If you still feel there is something abnormal, then you may contact the specialist doctor nearby for a physical evaluation. For further information consult a psychologist counsellor online -->
