The phenomenon of couples being extremely codependent on each other can sometimes lead to more serious consequences, such as a shared psychosis known as folie à deux. This condition involves the transmission of delusional beliefs within a close relationship, often resulting in irrational behavior. One famous case of suspected folie à deux was the Burari deaths in India, where a family of 11 members committed mass suicide due to shared psychotic beliefs. The term folie à deux was first described in 1877 by French psychiatrists and typically occurs in relationships where one partner influences the beliefs of the other.
Codependent relationships can create an environment conducive to the development of shared delusional beliefs. In most codependent relationships, there is usually a leader and a follower, with the follower partner being particularly vulnerable to adopting the dominant partner’s delusional beliefs due to low self-esteem and a need for approval. The fact that codependent partners live entirely enmeshed with each other can make the situation worse, as isolation from external reality and social connections can reinforce each other’s distorted views.
Treating codependency-linked folie à deux poses unique challenges, especially when these conditions co-occur. Primary intervention typically involves separating the individuals to break the cycle of delusions, which can be difficult for codependent individuals who derive their self-worth from the relationship. Pharmacological interventions, such as antipsychotic medications, are often used to address the primary individual’s psychotic symptoms, while treatment for codependency focuses on addressing underlying psychological issues and promoting healthier relational patterns.
Not all codependent relationships lead to shared psychosis, but the intersection of codependency and folie à deux is a complex study area that provides valuable insights into the power of interpersonal influence on mental health. By understanding these conditions, we can recognize the potential dangers of being too reliant on each other. If you are unsure if your relationship is healthy or unhealthy, taking the Relationship Control Scale can provide a science-backed answer.
