New research from France shows oxytocin can improve feeding and social skills in infants with Prader-Willi syndrome. These results are based on 18 infants (under 6 months old) and use well-established tests of sucking and swallowing, and behavioural measures including parent-infant interactions. A useful summary written by Dr Theresa Strong is available from The Foundation for Prader-Willi Research (USA) here.
