HGH
From PWS Notes
The thing I cling to above all is the belief that early stimulation can lead to cognitive development. I belive that GH allows for movement which allows for exploration of the environment which allows for the neurological stimulation which allows for cognitive development and normal intelligence. Read the posts of the moms of kids who went on GH early. Their kids are of normal intelligence and sometimes even smart. There is no proof that it is the growth hormone that allows for this, but I believe that it is a huge component.
