Posterior circulation strokes represent 20% of all acute ischemic strokes. Posterior circulation stroke patients are misdiagnosed twice as often compared to those with anterior events. Misdiagnosed patients likely have worse outcomes than correctly diagnosed patients because they are at risk for complications of the initial stroke as well as recurrent events due to lack of secondary stroke prevention and failure to treat the underlying vascular pathology.Understanding important anatomic variants, the clinical presentations, relevant physical examination findings, and the limitations of acute brain imaging may help reduce misdiagnosis. We present a symptom-based review of posterior circulation ischemia focusing on the subtler presentations with a brief discussion of basilar stroke, both of which can be missed by the emergency physician. Strategies to avoid misdiagnosis include establishing an abrupt onset of symptoms, awareness of the nonspecific presentations, consideration of basilar stroke in altered patients and using a modern approach to diagnosis of the acutely dizzy patient.

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...
