Serotonin syndrome controversies: A need for consensus

Area of Science:

• Neuroscience
• Clinical Pharmacology
• Toxicology

Background:

• Serotonin syndrome (SS) is a complex drug-induced condition from excessive central nervous system serotonergic activity.
• Despite decades of study, SS lacks standardized terminology, diagnostic criteria, and consistent therapeutic approaches.
• Historically associated with psychiatry and toxicology, SS is increasingly recognized in diverse clinical settings.

Purpose of the Study:

• To highlight the evolving clinical landscape of serotonin syndrome.
• To address the diagnostic and therapeutic challenges posed by SS in non-traditional settings.
• To emphasize the need for broader consensus on SS management.

Main Methods:

• Review of existing literature on serotonin syndrome.
• Analysis of case reports from various medical specialties.
• Discussion of clinical presentations and etiological factors.

Main Results:

• Serotonin syndrome cases are now prevalent beyond toxicology and psychiatry, appearing in perioperative, neurological, cardiological, gynecological, and pediatric contexts.
• SS can manifest at therapeutic drug dosages, differing from overdose-induced cases.
• Clinical presentations vary significantly, complicating diagnosis and management.

Conclusions:

• Serotonin syndrome is a multifaceted condition requiring wider recognition and understanding.
• Standardized diagnostic criteria and therapeutic guidelines are crucial for effective management.
• Interdisciplinary consensus is essential to address the complexities of serotonin syndrome.
