Aaron reports that there was an informational ad concerning "Fragile X" above my blog.

"Anxiety in both boys and girls manifests itself in various ways. Some persons with fragile X become very worried about changes in routine or upcoming stressful events (e.g., fire drills, assemblies). This is often referred to as "hypervigilance". Parents often report that their children stiffen up when angry or upset, becoming rigid and very tense. Sometimes, they simply tighten up their hands. Tantrums may be a result of anxiety and a feeling of being overwhelmed. Crowds and new situations may cause boys to whine, cry, or misbehave, in attempts to get out of the overwhelming settings."
