Folie à Deux – Shared Psychotic Disorder

Folie à deux is a shared psychotic disorder where the delusion is shared between two individuals.

Criteria for a folie à deux as described by Dewhurst and Todd:

  • definite evidence that the partners had been in intimate association
  • a high degree of commonality in the content of delusion, although the formal psychosis may differ
  • unequivocal evidence that the partners share support, and accept each other’s delusions

In the DSM -5 it is included under the section on psychotic disorders and does not exist as a separate entity.


Currently studying Psychotherapy , Cognitive psychology, Biological psychology, Counselling psychology and CBT and NLP. I believe in truth, honesty and integrity! ≧◔◡◔≦
