[Zenker's diverticulum as a cause of aspiration pneumonia and dysphagia in nonagenarian with moderate dementia].

The association between aspiration pneumonias and digestive symptoms is frequent in geriatric patients and is usually attributed to comorbidity, being the most frequent causes cerebrovascular disease or dementia. We present the case of a 90-year-old woman, with malnutrition associated with progressive dysphagia and episodes of aspiration pneumonia, due to Zenker's diverticulum, which was treated surgically. We provide a review of this disease and analyze the criteria that can be applied when considering surgical indication in the oldest-old with dementia.
