Rogers refers to PAS in her report on five divorce/custody cases in which the falsely accusing parent, all mothers in this sample, suffered from delusional disorder. The children were subjected to undue influence to get them to accept the accusing parent’s psychotic belief and concomitant rejection of the other parent in a severe PAS scenario. Where the child succumbed, a diagnosis of shared paranoid disorder, otherwise known as folie a deux might also be made. According to Rogers, the first stages of the mother’s delusional disorder were present to some degree during the marriage and exacerbated parental conflicts prior to the separation. However, these subtle signs were not immediately discernible as a psychiatric illness and were only recognized in retrospect, as the mother’s symptoms became worse in the course of the divorce and its attendant disputes. One of the severe PAS cases reported by Dunne and Hedrick appears to be an example of the mother developing delusional disorder.
