Up until just a few years ago, it was thought that a person with Down syndrome could not have autism. Well that perspective has changed dramatically.
Just a few years ago…less than 10 years ago, the mother a child with Down syndrome would simply be told that her child had Down syndrome with a severe cognitive impairment.
They would make no effort to find out the cause of the supposed cognitive impairment.
A mother might be told, ” This is part of what happens with ‘low-functioning’ Down syndrome”.
We now know that this is not true.
It turns out that children with Down syndrome are even more pre-disposed to have autism spectrum disorder than the rest of the population.
