Restlessness, Agitation and Delirium at the End Stages
The terms End Stage Restless, End Stage Agitation or Terminal Delirium are interchangeably used to describe the confused, restless and sometimes agitated and aggressive behavior that patients may suffer during the dying process. The word for delirium comes from the Latin term meaning “off the track,” and is not a disease in itself but rather an array of symptoms with different causes. Delirium and new onset confusion is extremely common among nursing home residents where it is found in as many as 80% of patients near death. Restlessness and agitation may also occur when emotional or spiritual issues are unresolved. In delirium, the patient usually has an acute, sudden and simultaneous impairment of memory, thinking and perception.
