Summary

Delirium ("acute confusional state")is characterized by an acute decline in attention and cognition, and is a common clinical syndrome in elderly patients. The purpose of this randomised, controlled, parallel group pilot trial is to explore superiority of clonidine vs placebo in decreasing delirium in patients diagnosed delirium at the acute geriatric ward. We will also study the feasibility of oral clonidine in a geriatric ward and effects of clonidine upon a variety of outcomes as a means to design a more definite study later.
