Status Dystonicus: An Updated Review on Diagnosis, Pathophysiology, and Management

Area of Science:

• Neurology
• Movement Disorders

Background:

• Status dystonicus (SD), or dystonic storm, is a rare, life-threatening condition characterized by continuous dystonic spasms.
• It often occurs in patients with generalized dystonia, particularly secondary forms linked to basal ganglia dysfunction and dopaminergic disturbances.

Purpose of the Study:

• To provide a comprehensive overview of the clinical spectrum, pathophysiology, triggers, and updated management strategies for status dystonicus.
• To highlight practical approaches for early identification and coordinated care of SD.

Main Methods:

• A narrative review of peer-reviewed literature from PubMed and Scopus databases.
• Appraisal of key consensus guidelines and case series focusing on etiopathogenesis, risk factors, grading, therapies, and outcomes.

Main Results:

• Early diagnosis, prompt triage, and adequate management are critical for improving survival and neurological outcomes in SD.
• Standardized clinical pathways and multicenter data are essential for advancing the understanding of SD's natural history and therapeutic efficacy.

Conclusions:

• Status dystonicus requires prompt recognition and multidisciplinary management to prevent multisystemic failure.
• Optimizing sedation, airway management, and disease-specific therapies, alongside trigger identification, are key management principles.
