Modern families, in recent times, are aware of autism and its related disorders. Most of them have a well maintained family tree that offers a defined family history.
When evaluating a child for autism, it is important to know about the family history and search for any genetic disorder that may have been in the family. Parents’ perception of autism has seen a considerable change that has, in turn, made them mature. They may consult the possibility, with counsellors, of their second child inheriting the same syndrome as its older sibling with autism.
In the past, parents may have been reluctant, but now their thoughts have changed remarkably.
Every parent while planning a sibling for their child/children with autism often have a query, “what is the threat of planning another child?” It is highly suggested that the parents must consult with a genetic counsellor and for early intervention for the unborn child having sibling with autism. A study has shown that:
- If a family has one child with autism, there is a 15 % chance that the next child may also have ASD.
- If the next child happens to be a male, then the risk is 2-3 times more than for girls.
Younger siblings, of children with autism spectrum disorder, are more likely to have ASD syndromes like language delays, learning difficulties, lack of social communication, repetitive behaviour and sensory sensitivities.
It is believed that autism is the effect of multiple genes interacting with each other. These genes are the root cause that develop a baby’s brain abnormally or make him/her vulnerable to other unknown neurological factors. There may also be a combination of genetic and environmental influences too, that may affect normal development.
If the child is born without any influence of ASD, there may be a possibility (negative) of intellectual ability, behaviour of the older sibling with autism to impact a healthy relationship between the two siblings. There is also a possibility (positive) of a sense of responsibility for the sibling with autism by the younger healthy sibling. Many of the siblings of children with autism function well with their younger siblings in adolescent and adult stages.
It is advisable for parents to gain more information on autism and the risk in welcoming a second child in the family that already has a child with autism. Modern families who want to have a child are very mindful of their family history.
So, YES, Things Have Changed!
