%X <B>UNASSIGNED: </B>Williams syndrome (WS) is a rare genetic disorder associated with a high prevalence of anxiety disorders. Evidence-based pharmacologic treatments for anxiety in WS are lacking. The purpose of this study is to provide naturalistic data on the use of buspirone for the treatment of anxiety in WS.<BR><B>UNASSIGNED: </B>Medical records of 24 individuals with Williams syndrome (ages 7-47 years) and anxiety who received treatment with buspirone were reviewed. Treatment response to buspirone was rated by assigning a retrospective Clinical Global Impression Improvement subscale (CGI-I) score.<BR><B>UNASSIGNED: </B>Twenty-three of 24 (96%) patients completed at least a 16-week treatment course with buspirone. Sixteen patients (67%; 95% CI 47%, 82%) were treatment responders (CGI-I ≤ 2). Only 1 (4%) patient discontinued buspirone due to a treatment-emergent side effect (nausea and vomiting). The most common side effect was nausea (13%). Twenty (84%) patients remained on buspirone at the time of their most recent follow-up visit.<BR><B>UNASSIGNED: </B>In this retrospective study, the majority of patients responded to a 16-week course of buspirone. Prospective studies are warranted to further assess the efficacy and tolerability of buspirone for anxiety in WS.
