Abstract:

Abstract We report the case of a 90 year - old female patient treated at our health centre whose main symptom was the presence of isolated visual hallucinations . The symptoms produced a state of intense concern to the patient and her family . The initial assessment by the primary care unit showed that no acute pathology was affecting the patient . So , the first option that was considered was cognitive impairment and the patient was referred to the Area Dementia Unit to exclude this pathology . However , after a neuropsychological examination , dementia syndrome was ruled out , and Charles Bonnet Syndrome , consisting of the appearance of visual hallucinations secondary to severe visual impairment , was considered instead . After five years , symptoms have almost completely disappeared and there are no signs of cognitive impairment . This shows the need to consider Charles Bonnet Syndrome in the differential diagnosis of visual hallucinations in elderly patients in primary health care .
