Folie simultanée

Folie simultanée

Folie simultanée is a rare psychiatric phenomenon where two or more individuals, usually in close emotional proximity, simultaneously develop the same or similar delusions. This condition is a subtype of folie à deux, which is a shared psychotic disorder. Unlike other forms of shared psychosis, in folie simultanée, the delusions arise independently but concurrently in the individuals involved.

Characteristics

Folie simultanée is characterized by the simultaneous onset of delusional beliefs in two or more individuals who are in a close relationship, such as family members, partners, or close friends. Unlike folie imposée, where one dominant individual imposes their delusions on another, folie simultanée involves the independent development of similar delusions without a clear primary inducer.

Symptoms

The symptoms of folie simultanée are similar to those of other psychotic disorders and may include:

• Delusions: Strongly held false beliefs that are resistant to reason or contrary evidence.
• Hallucinations: Perceptions in the absence of external stimuli, though less common in folie simultanée.
• Disorganized thinking: Difficulty in organizing thoughts, which may manifest in speech.

Diagnosis

Diagnosis of folie simultanée requires a thorough psychiatric evaluation. It is important to differentiate it from other types of shared psychotic disorders and to rule out other psychiatric conditions such as schizophrenia or bipolar disorder.

Causes

The exact cause of folie simultanée is not well understood, but it is believed to involve a combination of genetic, environmental, and psychological factors. The close emotional bond between the individuals involved is a significant factor, as it facilitates the simultaneous development of similar delusions.

Treatment

Treatment of folie simultanée typically involves:

• Separation: Temporarily separating the individuals involved to break the cycle of shared delusions.
• Psychotherapy: Cognitive-behavioral therapy (CBT) can help individuals challenge and change their delusional beliefs.
• Medication: Antipsychotic medications may be prescribed to manage symptoms of psychosis.

Prognosis

The prognosis for individuals with folie simultanée varies. With appropriate treatment, many individuals can recover fully, although some may continue to experience residual symptoms or relapses.
