Hi there, i have a 4 year old daughter who has a simian line on her right hand, she has extreme behavior problems, and violent tantrums, she has disturbed sleep etc, is there a link between a simian line and these issues? She has always had behavior issues etc but the older she gets the more extreme they are, she will not sit still and is always adjitated, she will not take any form of dicapline at home or at nursery, although she is very intelligent for her age the nursery want to keep her back a year because of her behaviour and lack of concentration, i have done a ADHD test online and it states that she is on the spectrum for ADHD but i do think that this has more to do with her having a simian line. Does anybody have any advice or answers or similar problem?
