Psychogenic Pseudosyncope: Clinical Features, Diagnosis and Management

Area of Science:

• Neurology
• Psychiatry
• Cardiology

Background:

• Psychogenic Pseudosyncope (PPS) presents as Transient Loss of Consciousness (TLOC) without the typical hemodynamic or electroencephalographic changes seen in syncope.
• Distinguishing PPS from syncope is crucial for appropriate patient management.

Purpose of the Study:

• To review the historical aspects, clinical features, diagnostic methods, and therapeutic strategies for Psychogenic Pseudosyncope.
• To provide an overview of current diagnostic classifications and neurobiological underpinnings of PPS.

Main Methods:

• Review of existing literature on Psychogenic Pseudosyncope.
• Analysis of clinical clues, diagnostic criteria, and treatment outcomes.
• Emphasis on the role of tilt testing in diagnosis.

Main Results:

• Detailed patient history is key, with specific clinical clues suggesting PPS, such as prolonged episodes and unusual triggers.
• Tilt testing is the gold standard, documenting normal physiological responses during an event.
• Empathetic communication of the diagnosis can reduce attack frequency.

Conclusions:

• Accurate diagnosis of PPS requires careful clinical evaluation and objective testing, differentiating it from true syncope.
• Cognitive-behavioral therapy offers the most robust evidence for managing PPS.
• Integrated treatment approaches, including psychological interventions, are beneficial.
