A Challenging Hypoactive Delirium Case with Multiple Etiological Considerations

Delirium is a common clinical syndrome characterized by disturbed consciousness, cognitive function or perception. It is associated with poor outcomes, unless prevented and treated urgently. Hypoactive delirium is more common and is associated with poor prognosis because it is less frequently recognized. Typically, the causes of delirium are multifactorial. The aim of this case report was to draw attention to the fact that both hypoactive delirium itself and, more importantly, the underlying multiple causes may be overlooked in older adults.
