Autism can have effects, good and bad, on a disabled child's siblings
from The Washington Post
A fair amount of research has been done on how autism impacts the family. Most of it has focused on how parents are affected. The small amount of sibling research tends to center on issues of academic performance, mood disorders and social performance, and is far from conclusive. A 2006 review of the research in the Journal of Intellectual and Developmental Disability found that while some researchers were uncovering "deleterious outcomes," others were finding siblings who were well adjusted or whose challenges were of "low magnitude and non-significant."
