[Prevalence of mental disorders in French prisons: A systematic review].

Introduction: The prevalence of psychiatric disorders among prisoners remains a major public health issue worldwide. In France, despite the increasing number of persons who are incarcerated (+30% between 1992 and 2002 with a 120% prison overcrowding), and a historical concern about the mental health of persons in detention and its management, no systematic review has been published on this subject. The aim of this article is to present the results of a systematic review of the literature on the prevalence of psychiatric disorders in French prisons.

[Addiction management in prisons].

High levels of substance-related disorders among incarcerated people have been documented and there is a lot of drug users in French prisons. Several health and social workers are involved in the management of people dealing with addictions in prison. The coordination between substance use and mental health services in correctional settings and in the community is fundamental to ensure treatment continuity for these people.

[Psychiatric emergencies in teleconsultation: legal and practical aspects].

In the context of the Covid-19 pandemic, teleconsultation is an obvious solution in psychiatry to ensure continuity of care and facilitate access. However, the digitisation of ambulatory practices raises a certain number of reservations, in particular concerning the remote management of psychiatric emergencies. These situations, because of the specific aspects they cover, are in fact upsetting texts and recommendations of good practice in terms of teleconsultation.

Circular inference in bistable perception.

When facing ambiguous images, the brain switches between mutually exclusive interpretations, a phenomenon known as bistable perception. Despite years of research, a consensus on whether bistability is driven primarily by bottom-up or top-down mechanisms has not been achieved. Here, we adopted a Bayesian approach to reconcile these two theories.
