[Functional neurological disorders: history and current situation].

Functional neurological disorders are characterized by a variety of neurological symptoms that are not explained by an identifiable organic pathology. Despite their significant prevalence and major impact on quality of life, their recognition and management remain inadequate. Formerly known as hysteria, modern criteria (Diagnostic and Statistical Manual of Mental Disorders, 5th edition [DSM-5]) allow a positive diagnosis, distinct from malingering. These disorders often lead to long periods of misdiagnosis, high levels of care consumption and significant socio-economic repercussions, including frequent loss of employment. Improving the training of professionals, developing specific treatments, reducing stigmatization and providing support for patients are crucial to meeting this public health challenge.
