Organic brain syndrome. The psychiatric imposter

Area of Science:

• Neurology
• Psychiatry
• Emergency Medicine

Background:

• Differentiating organic brain syndrome (OBS) from functional psychiatric illness presents diagnostic challenges in emergency settings, particularly with prominent psychiatric symptoms.
• Accurate and timely diagnosis is crucial for appropriate patient management and outcomes.

Purpose of the Study:

• To evaluate the effectiveness of a specific screening tool for identifying OBS in emergency department patients with psychiatric symptoms.
• To improve the diagnostic accuracy in distinguishing OBS from primary psychiatric disorders.

Main Methods:

• A retrospective analysis of 1,140 medically cleared patients presenting with predominantly psychiatric symptoms.
• Application of four screening criteria: disorientation, abnormal vital signs, clouded consciousness, and age over 40 with no prior psychiatric history.
• Identification of OBS cases based on these criteria.

Main Results:

• Thirty-eight cases of OBS were detected using the four screening criteria.
• Twelve of the identified OBS patients required admission to a medical unit.
• The screening tool demonstrated utility in identifying OBS among patients with behavioral aberrations.

Conclusions:

• The proposed four-criterion screening tool can aid emergency department physicians in differentiating OBS from functional psychiatric illness.
• Increased physician awareness of OBS clinical manifestations is vital for accurate diagnosis.
• Early detection of OBS can facilitate timely medical admission and treatment.
