The term refers to the inability to recognise a familiar face, a rarely isolated symptom. Prosopagnosia is thought to result from brain lesions, predominantly at the ventral right temporo-occipital junction. There are more common cases of developmental prosopagnosia, where no lesion has been identified. Capgras syndrome (CS), described by Joseph Capgras (1873–1950), a psychiatrist, consists of the persistent belief that a close relative, identified, has been replaced by a look-alike. SC, considered a delusional disorder of identification or familiarity, has been described in chronic psychoses, mainly schizophrenia. It is also reported in the course of neurodegenerative diseases (mainly Alzheimer's disease, Lewy body dementia, Parkinson's dementia). Lesion-based forms have recently been described. Prosopagnosia and SC were initially thought to result from mirror-image lesions involving a single factor, one affecting an overt ventral circuit for face recognition (in the case of prosopagnosia), the other a covert dorsal circuit involved in emotional and vegetative responses (in the case of CS). Lesion network mapping has been used in both lesion-related conditions and suggests a more complex figure. Lesions causing prosopagnosia were correlated with one of the main regions associated with face recognition, the right fusiform face area, and anticorrelated with left frontal regions possibly involved in visual attentional control. In lesional forms of CS or other delusional misidentification syndromes, there was a correlation with left retrosplenial cortex, an area associated with familiarity processing, and a correlation with right frontal regions associated with belief evaluation. This finding supports the intervention of two factors in CS, one generating the impaired familiarity associated with perception and the other the genesis and persistence of a delusional idea. The debate on the mechanisms of CS is not settled, especially as it is limited to its lesional forms, but studies using lesion network mapping already mark a more general paradigm shift, with attention shifting from lesions (clinico-anatomical method) to circuit dysfunction.</div></div>","PeriodicalId":7992,"journal":{"name":"Annales medico-psychologiques","volume":"182 9","pages":"Pages 862-866"},"PeriodicalIF":0.5,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142659381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While working on nitric acid, the English chemist Joseph Priestley forgot a gas he called “nitrous air” for two months in contact with mercury and iron nails. He thus discovered a new gas which supports combustion, but which is fatal for animals. At that time, few instruments existed, and scientists tasted and inhaled their discoveries to study them. Writers were called upon to test Priestley's air and find the most accurate words to describe its extraordinary effects on the human mind. Humphry Davy, a young English chemist, was passionate about nitrous oxide. He synthesized it late in the evening at the Pneumatic Institute and inhaled it regularly, sometimes with other substances, including wine. In his book Researches, Chemical and Philosophical, chiefly concerning Nitrous Oxide and its Respiration, he specified that his health had deteriorated with the repetition of these experiments from April 1799 to June 1800, evoking disorders similar to what we observe today with the recreational use of N<sub>2</sub>O cartridges. This gas will subsequently inspire poets and philosophers and become popular in circuses and fairs, where it was used to entertain crowds. In the 19th century, in France, a first wave of concern about the use of Nitrous oxide appeared following cases of death and madness among users. In the 20th century, recreational use remained scattered until the 1990s. It circulated at this time, mainly on the party and techno scene where it was inhaled from whipped cream siphon cartridges, using balloons, alone or in combination, to enhance the effect of other substances such as ecstasy for example. Its ability to block NMDA receptor activity makes it a product that modifies perceptions and the coherence of thought: an effect similar to that caused by ketamine. Its medical potential first came to light in dentistry. Horace Wells, an American dentist, attended a public “laughing gas” demonstration. A man who had just inhaled it fell and injured his calf. He showed no pain. The dentist then had the idea of testing it on himself by inhaling nitrous oxide and having his assistant pull out a tooth, with success. Then he used it on his patients for pain-free care. In France, it was Apolloni Pierre Préterre who developed the use of nitrous oxide for dental care. In 1866, he filed a patent for his invention, which synthesized and administered N<sub>2</sub>O for anesthetic purposes. He developed a mask that allowed for the inhalation through the mouth and nose: the use of anesthesia was quickly adopted. However, during the Franco-Prussian War in the 1870s and the subsequent great demand for anesthesia, nitrous oxide was abandoned in favor of chloroform, which was easier to use. Today, its place is essential and unique among the therapeutic options against pain. Its action is rapid, with few side effects.

This innovative approach, which has been neglected due to historical biases rather than empirical evidence, is now experiencing a renewed interest among clinicians. Contemporary research, equipped with advanced methodologies and a rigorous scientific approach, is showing significant therapeutic potential for a range of mental health disorders. In Switzerland, the legal framework authorizes the medicinal use since 2014 for exceptional authorizations for the medicinal use of LSD and psilocybin for therapeutic purposes, under strict regulations.</div></div><div><h3>Method</h3><div>We provide a comprehensive description of the PAP protocol implemented at the Geneva University Hospitals, beginning with its inception in September 2020. Our methodological outline includes the administrative and clinical selection criteria for patient eligibility; the preparatory sessions designed to introduce the patients with psychoeducation interventions and the analysis of intention and therapeutical objectives; the controlled administration of psychedelics in a supportive environment; and the integration sessions that follow psychedelic experiences. Our protocol emphasizes safety, ethical considerations, and the importance of a supportive therapeutic relationship throughout the process. We also describe questionnaires we use to qualify and assess the alteration in the state of consciousness, namely The Five Dimension Altered States of Consciousness (5AD-ASC) and the Mystical Experience Questionnaire (MEQ). Since the start of the program in September 2020 and up to February 2024, a total of 224 personal authorizations (114 LSD, 110 Psilocybin) have been issued to the Geneva University Hospital PAP team, for a total of 396 individual sessions.</div></div><div><h3>Discussion</h3><div>The core argument presented in this article is that the psychedelic-induced alteration of consciousness is a novel therapeutic tool, which works as a potent catalyst that can be synergistically combined with traditional dialogue-based psychotherapy.

Many of these studies are part of the history of ideas: they examine in particular the relationship between the newly developed concept of schizophrenia and other existing concepts, above all that of dementia praecox founded by Emil Kraepelin. Other studies relate to social history: they analyze the emergence of schizophrenia as gender-related or as a phenomenon influenced by political or economic factors. However, whether they consider schizophrenia as a scientific or as a social object, none of these studies provide a clinical description corresponding to everyday practice in psychiatric institutions at the level of the inpatient population. Studies on the history of ideas are based on clinical descriptions from psychiatric textbooks or scientific articles, and are therefore far from everyday practice. The discrepancy between science-in-the-making and published science has already been widely described. Social history studies are based on clinical descriptions from medical archives, but these only concern the situation of a single patient or a small number of patients. Moreover, they exclusively focus on the social situation of patients and not on everyday medical practice, such as diagnosing patients. The aim of this study is to describe the clinical features associated with the diagnosis of schizophrenia at the Strasbourg University Clinic of Psychiatry at the time of its introduction into clinical practices (1929–1931).
