“…Any reversal of the cause of their visual loss like cataracts is associated with a resolution in symptoms as is, quite paradoxically, complete loss of vision [17]. As the condition can be associated with elderly who are also socially isolated, addressing such issues has been proposed as part of a comprehensive management plan [18,19].…”

“…Éstos incluyen el aislamiento social, [19][20][21] la timidez y, en general, una calidad deficiente en los contactos sociales, 19 la enfermedad cerebro-vascular, 21 el cansancio y los trastornos del estado de alerta, el estrés, la sugestión, 8 el nivel de visión, la iluminación y la hora del día. 6 Cabe destacar que el estudio de Gilmour et al 6 no encontró que la edad, el vivir solo, ni la viudez fueran factores de riesgo.…”

IntroductionSome patients, after brain or peripheral injuries, lose a sensory function, such as sight or hearing, but paradoxically experience complex hallucinations related to the function they have lost. It is known that this phenomenon may appear with injuries at any level in the visual pathway, especially in the retina. ObjectiveTo review the existent bibliography on the Charles Bonnet syndrome to establish the state of the art with regards to this phenomenon. MethodThe databases PubMed and PsychInfo were searched for articles containing the following keywords: Charles Bonnet syndrome; visual hallucinations; peduncular hallucinosis; Charles Bonnet; sensory deprivation. We included those related to the subject. We also included the classic texts referring to this phenomenon and the articles mentioned in the literature. ResultsIn the present study, we describe the history of Charles Bonnet syndrome, clinical presentation, risk factors, diagnostic criteria, treatment employed, similar conditions and the theories seeking to explain it. Discussion and conclusionTo date, the diagnostic criteria for Charles Bonnet syndrome remain controversial, especially those concerning the absolute preservation of insight as a sine qua non factor to establish the diagnosis. Conclusion: Described since the 18th century, the Charles Bonnet syndrome corresponds to the prototype of visual hallucinations in patients with visual deprivation, although, according to the present review, its phenomenology is vast, remaining unclear if it corresponds to the prototype of hallucinations with preserved insight.Key words: Charles Bonnet syndrome, visual formed hallucinations, insight, neuropsychiatry. RESUMEN IntroducciónExisten pacientes que, después de lesiones cerebrales o periféricas, pierden alguna función sensorial, como la vista o el oído. Paradóji-camente, después de perder esta función, presentan alucinaciones complejas relacionadas con la función perdida. Se sabe que este fenómeno puede presentarse ante lesiones en cualquier nivel de la vía visual, especialmente en el nivel de la retina. ObjetivoRevisar la bibliografía existente acerca del síndrome de Charles Bonnet para conocer los últimos avances con respecto a este fenómeno. MétodoSe revisaron las bases de datos de PubMed y PsychInfo con las siguientes palabras clave: síndrome de Charles Bonnet; alucinaciones visuales; alucinosis peduncular; Charles Bonnet; privación sensorial. Se incluyeron aquellos artículos que efectivamente trataran del tema. Asimismo, se revisaron los textos clásicos referentes a este síndrome y los artículos mencionados en la bibliografía encontrada. ResultadosEn el presente artículo se describe la historia del síndrome, el fenó-meno clínico, los factores de riesgo, los criterios diagnósticos, los tratamientos empleados, otros fenómenos similares y las teorías propuestas para explicarlo. Discusión y conclusiónA la fecha continúan siendo controvertidos los criterios diagnósticos del síndrome de Charles Bonnet, en especial en lo referente a la preserv...

“…Little is known about the etiology or pathogenesis, although theories abound. The syndrome may be associated with loneliness and low extraversion in the visually handicapped (Teunisse et al, 1999), energy loss or exhaustion (associated with compromised general health and a raised temperature) (Paulig and Mentrup, 2001) and the use of beta-blocker medication (Teunisse et al, 1998). It was associated with the use of a mobile phone in a single patient (Paulig and Mentrup, 2001).…”

“…Some authors claim that impaired visual acuity is a necessary prerequisite for CBS (Eperjesi and Akbarali, 2004); others have suggested that more generalized sensory deprivation is an important contributing factor (Teunisse et al, 1999). Pliskin et al (1997) suggested that the criteria should also include cognitive defects on formal neuropsychological testing, as their study of 15 elderly patients presenting with CBS showed that they all had significantly worse cognitive function (consistent with the early stages of dementia) than 11 matched controls.…”
