Mrs Dayal and her son were diagnosed to have Shared Psychotic Disorder .This is a condition where a healthy person shares the delusion of a psychotic person. The first case is called the secondary case and the second is the primary case. The delusions are induced in the secondary cases which usually disappear when both are separated. This disorder is seen in long term relationships in which one person is dominant and other is passive. Generally the people involved are isolated and have a close emotional link. The cause of shared psychotic disorder is unknown but social isolation and stress plays a role in its development.
Basically 3 important symptoms are required to make the diagnosis
The treatment recommended is to separate the secondary partner from the source of the delusion. The primary case has to be started on anti psychotic medicines. If the secondary case symptoms do not disappear, anti psychotic medication may be considered. Prognosis is good if the partners are separated and do not reunite. Psychotherapy for the secondary partner is most important for him or her to realize the existence of delusions.
