As children with attenuated Hunter syndrome become older, their attention and activity level may improve, although issues such as low self-esteem may emerge as they become more self-aware and compare themselves with their peers.
Sports and other physical activities may be a key place where these feelings manifest, as there is a strong association between sports participation and self-image and psychological well-being, particularly among young adult males. There is a possible negative impact on self-image among students who are not skilled at sports, although their own belief in their ability seems to have a greater impact than their actual ability.
As these issues in young adult life likely stem from self-esteem and perceptions of the self, early intervention to promote self-esteem and a sense of competency may help. It is important to remind your child that support is available to them throughout all stages of their life as they grow into adults; there are other patients who have experienced how they are feeling and they may find it helpful to reach out to them or join relevant support networks.
