Pseudodelirium

Area of Science:

• Psychiatry
• Neurology

Background:

• Acute functional psychoses are psychiatric conditions that can present with symptoms overlapping those of delirium.
• Distinguishing between primary psychiatric disorders and delirium is crucial for appropriate patient management.

Observation:

• Two case histories demonstrate how acute functional psychoses can present with clinical features resembling delirium.
• These cases highlight the potential for misdiagnosis when the underlying psychiatric nature is not recognized.

Findings:

• The term "pseudodelirium" is proposed to describe functional psychoses that simulate delirium.
• This proposed terminology aims to increase clinical awareness of this diagnostic challenge.

Implications:

• Adoption of the term "pseudodelirium" may improve the early identification of psychiatric illness.
• Facilitating earlier diagnosis can lead to more timely and effective psychiatric treatment, improving patient outcomes.
