It is extremely important that we become involved in research as to the cause of the condition. We are not sure of the cause but it is quite possibly a genetic disorder of brain chemistry. What we do know is that there are about four boys to one girl affected and that it comes on at the time of cognitive development at about 18 months to two years. This is just when a child is beginning to flower and develop and it is extraordinarily distressing for parents who, as Senator Ross so rightly said, then cannot get anyone to see and assess their children.
