Dear Doctor Letter

“Research” Results

April 2007: preliminary results of 2006-2007 survey now online

The following are the results of 3 questionnaires/research studies, which families have participated in. I believe that it’s the first “study” (non scientific) that looks at children with Hydranencephaly and identifies common factors and differences in their abilities, care needs, etc. The first questionnaire was available at Flashbase over approximately 12 months. Fifty eight people participated. The 2nd was available via the yahoogroups polls section. Each question had a different number of participants. Only people subscribed to the mailing list were able to participate, and those who had more than one child with the condition could only answer for one child. Therefore I don’t think it’s as accurate. The 3rd was conducted online via a form and via snail mail and was available from September 2002-February 2003. 81 families participated. I am including the numbers in the basic statistics in brackets. I am also including in brackets some of the statistics on the children with hydranencephaly who have died.

I've found some of the results of this study surprising and contrary to what we've previously assumed about this condition and others were expected.  The main results appear on this page but to get a true picture of our children their stories also have to be seen.
