I have never heard of childhood dementia and a quick Google search seems to point only on this website and other sites with exact same wording.
The numbers they give seem impressively high for a disorder that is barely documented on the internet.
The symptoms are basically normal children behavior.
This looks like a scam design to scare parents into buying something.
It might look like this by accident but I would do a lot more research if I were to donate or take their advice.
How will they install ac units ?
