Background: Folie à deux, or shared psychotic disorder, has traditionally been associated with close interpersonal relationships, emotional dependency, social isolation, and physical proximity. However, modern communication technologies may allow emotionally significant relationships to persist despite physical separation.
Objectives: To describe a folie à deux-like clinical presentation occurring between two formerly intimate individuals who remained physically separated but maintained sustained communication through telephone contact.
Case Presentation: A 19-year-old woman developed prominent auditory and visual hallucinations involving her former boyfriend after their relationship was forcibly terminated by her family. She reported seeing him entering her room, sitting beside her, and conversing with her despite his physical absence. She subsequently received psychiatric treatment and improved. During the following period, she maintained secret telephone communication with her former boyfriend and repeatedly described these experiences to him. Approximately two years later, the former boyfriend, aged 24 years, developed remarkably similar experiences involving the woman. He reported seeing her entering his room, walking around, sitting beside him, and conversing with him despite her physical absence. The phenomenological similarity and temporal sequence raised consideration of a shared psychotic phenomenon mediated through sustained virtual communication.
Discussion: The cases demonstrate a possible folie à deux-like phenomenon in the absence of physical proximity. The emotionally intense prior relationship, social isolation, repeated telephone communication, content-specific similarity of hallucinations, and temporal sequence support the hypothesis of interpersonal transmission or reinforcement of psychotic experiences. However, causality cannot be established from a single case, and independent psychotic disorders and other differential diagnoses require careful consideration.
Conclusion: Shared psychotic phenomena may potentially occur despite physical separation when a psychologically significant relationship is maintained through sustained virtual communication. The concept of "virtual proximity" may provide a useful clinical framework for understanding such presentations, although empirical research is required before causal conclusions can be drawn.
