Disguises of delirium

Area of Science:

• Neurology
• Geriatrics
• Psychiatry

Background:

• Delirium is an acute, fluctuating disturbance of consciousness characterized by inattention and cognitive changes.
• The syndrome has diverse etiologies and varied clinical presentations, making it challenging to diagnose.
• Behavioral symptoms of delirium are frequently misattributed to pre-existing psychiatric conditions.

Observation:

• Four patients presenting with overt signs and symptoms of delirium had their condition overlooked.
• The study details the protean features of delirium in these cases.
• Misdiagnosis occurred because behavioral changes were attributed to functional disorders.

Findings:

• Delirium can manifest with a wide range of symptoms, complicating recognition.
• The syndrome's varied etiology contributes to diagnostic challenges.
• Overlooking delirium can lead to delayed or missed critical interventions.

Implications:

• Increased awareness and recognition of delirium's diverse presentations are essential.
• Healthcare professionals should consider delirium in patients with acute behavioral changes, especially the elderly.
• Prompt diagnosis and management of delirium can prevent severe outcomes and improve patient prognosis.
