Folie à Deux (pronounced fo-lee uh doo) is a rare mental health disorder that can be difficult to understand but can be treated successfully when professional help is sought. This article will discuss what it is, the treatment and provide resources for persons dealing with a loved one with this disorder.
Folie à Deux literally means a madness or insanity shared by two people. In essence, it means two people that share a delusion and support each other in their delusion. A delusion is a false belief that a person strongly believes and does not go away just by telling a person that it’s not real. It requires treatment and possibly medication.
Folie à deux is a rare disorder and there is not much information on it. Because of that, it is not known how many people suffer from this as there are only case studies that are shared.
It is unknown what causes this disorder, but what is known is that one person suffers from a psychotic disorder and the other person comes to believe the delusion. Almost 100% of the cases involve persons in close emotional relationships, such as husband and wife, siblings or parent and child. This disorder has rarely been seen in persons who do not have a close relationship. The person who comes to believe the delusion will most likely have a predisposition to psychosis, although it may never manifest completely. Research shows there is no way to prevent this disorder and almost impossible to predict whether a person will ever develop it.
While it is unknown why this disorder happens, there are some signs to look out for. Most people with Folie à Deux are passive in nature, may be socially isolated, may have dependent personality traits, is very dependent on the person who has a psychotic or delusional disorder, and are more often women.
Common characteristics of someone with Folie à Deux is:
The DSM 5 states all of these must be present to have a diagnosis of Folie à deux:
There are other conditions in which two people share a delusion but are even rarer:
Folie à deux is when two people share the same delusion and only one person is diagnosed with a psychotic disorder while the other person who took on the delusion is relatively healthy. A delusional disorder, by contrast, is when a psychotic disorder is not shared with another person but rather is independent in nature.
Primary Delusional Disorders are delusions that may happen out of the blue and cannot be understood by others. It is a delusion with no basis or explanation.
Secondary delusions are ones that, although they are not correct, may come from an experience or situation that happened that has led the person to now believe the delusion. An example would be when a person is depressed and thinks that they are depressed because they are being punished for something.
Schizophrenia is a psychotic disorder where an individual hears voices and will often have delusions or hallucinations, however hearing voices are the hallmark of this disorder.
Psychosis refers to a person’s thoughts and emotions being so impaired that they are unable to function on a daily basis. This differs from Folie à Deux where a person is usually functioning in all aspects of their life but has adopted the delusion.
In 2014, two 12-year-old girls (Morgan Geyser and Anissa Weier) killed a man they thought was Slenderman (a fictional character whom they thought was real), because they felt that if they didn’t then he would kill them and their families. Later it was determined by a psychologist who assessed both girls, that Morgan Geyser had early-onset schizophrenia, and her friend Anissa Weier came to adopt the same delusion after the two friends became close. According to Anissa’s parents, she was shy, didn’t have many friends, and eager to make friends. After the two girls were arrested and separated, slowly Anissa began to realize that her delusion was false after receiving therapy and support from her family.
Coping with Folie à Deux can be stressful and confusing. Seeking support from others and seeking professional help for yourself if you have a family member with this can be beneficial. It’s important that family and friends understand this disorder as much as possible and support their loved one who may have this disorder. Remember this is not a disorder by choice and the person affected actually believes this delusion. They are not doing this to seek attention and it is not a sign of weakness, rather it is a serious disorder that should be carefully handled with the help of a licensed mental health professional. Separating the two people is the best way to treat this disorder but can be difficult and should not be forced without the help of others.
It can sometimes be difficult for someone to recognize this Folie à Deux because the affected person may appear to be relatively healthy and seem to act “normal”. When interviewing a person with this disorder, nothing may seem out of the ordinary until the delusion is discussed. The affected person may become anxious or angry when challenged with this delusion and should, therefore, be done with the support of others.
The most powerful treatment for Folie à Deux is separating the two individuals. It has been proven that when the person who has been influenced is separated from the primary person and given therapy, the delusion tends to diminish. At times it may be necessary to prescribe medication for the affected person when separating doesn’t work. The person affected would benefit from therapy to understand why they came to believe the delusion and to work on other things such as dependency issues, self-esteem, and confidence. Family therapy can also be helpful to assist the entire family in understanding why this happened and how to better support the person affected.
Medication is often used to assist the person who has the psychotic disorder with their symptoms. Although it is not usually used on the secondary person, it may be worth considering if other techniques don’t work. Medications such as antipsychotics work well. These medications include Haldol and Thorazine (which are considered first-generation antipsychotic medications). These medications should be given by a psychiatrist and the patient needs to monitored closely.
There are no known home remedies for persons suffering from Folie à Deux.

Folie à Deux is a rare mental health disorder that is recognized among mental health professionals as a delusion shared between two people, with one being the primary (the person with a psychotic disorder that has the delusion) and the other person being secondary (the person who comes to believe this delusion). The secondary person is the one who is diagnosed with Folie à Deux as they are the one that is relatively healthy but have taken on the delusion.
This disorder occurs when two people have an extremely emotional closeness that is sometimes unusual in nature. There is usually a dependency by the secondary person on the primary person and some characteristics that have been seen in persons with Folie à Deux are shyness, isolation, and low self-esteem.
While much research doesn’t exist, there have been cases studied and it has been determined that this disorder can be treated by being separated from the primary person and at times may have to take medication for a short period of time.
