Charles Bonnet’s Syndrome: A Case Report from Brazzaville (Congo)

Williams Atipo Tsiba, G Noa G, IA Diomande


The Charles Bonnet’s syndrome (CBS) is a set of complex hallucinations, strictly visual, occurring at any age in the absence of any neuropsychiatric disorder. These hallucinations are the consequences of a profound impairment of vision, usually following a cataract, glaucoma or macular degeneration. Its prevalence is probably underestimated. The poor knowledge of this syndrome by the health personnel is the main reason for diagnostics errors and erroneous treatment in the presence of hallucinations in the elderly. Furthermore, many patients prefer living without talking about the hallucinations, because of fear to be considered as insane or a person with a serious psychiatric illness such as Alzheimer's disease. Here, we report the first documented case of CBS linked to cataract in the University Hospital of Brazzaville (UHB) in a patient of 84 years.
