With about 100 case studies, the incidence of the disorder is not precisely known. Individuals of multiple backgrounds have been reported as having the disorder. The syndrome was historically thought to be more common in men. However, Whitlock speculates that the higher reported rate of<unk>  in men might be due to the greater proportion of men who are incarcerated. It has been most frequently seen in individuals ages 15 to 40 and has also been observed in children. This wide age range is derived from case studies, and therefore may not be an accurate estimate.<unk>  has also been observed in groups other than prison populations.
