Regarding the enuresis issue (bedwetting), a great deal of research seems to indicate that bed wetting is actually a more is a possible sign of sexual abuse or parental neglect
, especially when accompanied by other behavioral markers (i.e. acting out, violent behavior, delusions of either persecution or grandeur).
Basically, the more "modern" view on the trifecta is that it's a clear sign that there's some serious disturbances in a child's life, whether abuse, sexual assault, neglect, or a mental disorder. And with these negative factors often comes a later diagnosis of a personality disorder such as Antisocial Personality Disorder.
