Transient cognitive disorders (delirium and pseudodelirium) are highly
prevalent among the elderly, especially those with brain damage. Delirium
is a common feature of physical illness or drug intoxication in elderly
patients and requires prompt medical attention. While potentially
reversible, delirium may herald death. Pseudodelirium may be induced by
psychosocial stress or accompany a functional mental disorder. Transient
cognitive disorders must not be confused with dementia, a chronic syndrome.
The author discusses clinical features, etiology, pathogenesis, diagnosis,
and treatment of delirium and related transient disorders of cognition in
the elderly.Abstract Teaser
