My brother has Aspergers and now DHS has Taken his son

My brother has a Form of Aspergers BUT is not violent towards his son.
Is there any support for parents with this problem that have children ( his son doesnt have it )
As my Nephue is deteriorating fast in the Hands of the DHS and has missed hospital apointments while in the care of the government. He is now very sick since being in THERE CARE. We are un able to find support and are at a loss as to where to goto next. THIS IS A LONG SHOT COMING TO THIS WEB SITE.
We have asked the DHS if they took the child due to any phisical abuse

We asked and They said
did he beat him - no
did hit him - no
was he not fed - no

Then why ???????????????
