title: Folie à deux: a case report.
abstract: Folie à deux is a relatively rare mental disorder first described in France in 1877 by Lasègue and Falret. However, folie à deux is still a matter of study and debate today as it remains a challenge for psychiatrists. The aim of our work is to report a clinical case of folie à deux, subtype A of Gralnick, between an inducer daughter and an induced mother who lived quite socially isolated and had a strong and close relationship. In the clinical case presented, folie à deux was easily diagnosed but its treatment proved to be a higher challenge. The main diagnosis of the inducer patient was also quite interesting. Many years after it was first described, folie à deux is still an interesting and challenging disorder to psychiatrists, especially concerning its pathophysiology and treatment.
