Delirium Hub: Introduction

Delirium is the onset of sudden confusion. Characteristic features include difficulty concentrating, disorientation, difficulty with understanding or memory and personality changes (becoming more irritable or more withdrawn). The condition can be distressing for the patient and their loved ones.

The causes of delirium are multifactorial and it is a sign of an underlying physical illness. The links below provide additional information on what to be aware of where delirium is suspected or confirmed.
