Delirium refers to an acute state of confusion. Delirium is not in fact a disease in itself but rather a syndrome caused by multiple factors and results in a number of symptoms. Delirium is marked by a disorder of cognition and marked cerebral dysfunction. However, it is a transient condition that is usually reversible.
Delirium often remains undiagnosed or misdiagnosed causing further problems. Commonly mistaken for depression, schizophrenia or dementia, the symptoms of delirium tend to set in suddenly and should be treated as a medical emergency.Alternative Names
