Folie a deux: a case report

Folie à deux is a relatively rare mental disorder first described in France in 1877 by Laségue and Falret. However, folie á 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 á 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 á 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 á deux is still an interesting and challenging disorder to psychiatrists, specially concerning its pathophysiology and treatment.
