An MRI revealed aqueductal stenosis with resulting hydrocephalus. Two months ago, he underwent an endoscopic third ventriculostomy. Two weeks post surgery, swelling developed at the site. There was an infection, and subsequently, a shunt was placed in his head. I have been told that it will be about 3-6 months before his brain shrinks down to normal size.
Autism can be present to varying degrees and the superimposed hydrocephalus complicates the issue.
A best guess would be that your son will see improvement within the next few months from putting in the shunt, as is typical in kids with hydrocephalus alone. After this period you are left with the autism as a baseline for further development. Sorry we can't be too specific on this one.
