Autoimmune Encephalitis in Acute Care-Pathology, Diagnosis, and Management

Area of Science:

• Neuroscience
• Immunology
• Critical Care Medicine

Background:

• Autoimmune encephalitis (AE) is an immune-mediated brain inflammation causing diverse neurological symptoms.
• AE can lead to life-threatening complications requiring intensive care unit (ICU) admission.
• Diagnosis and management of AE present significant challenges in acute and critical care settings.

Purpose of the Study:

• To synthesize current knowledge on autoimmune encephalitis in acute and intensive care.
• To highlight diagnostic and therapeutic challenges in critically ill AE patients.
• To provide a comprehensive overview for optimal patient care.

Main Methods:

• Review of current literature on autoimmune encephalitis pathophysiology, epidemiology, and clinical manifestations.
• Analysis of diagnostic approaches including autoantibody detection, neuroimaging, and EEG.
• Synthesis of immunotherapeutic strategies and management of critical complications.

Main Results:

• AE presents with varied neurological syndromes, including seizures, altered consciousness, and movement disorders.
• Diagnosis is complex, especially in antibody-negative cases, requiring a multimodal approach.
• Effective management involves prompt immunotherapy and aggressive supportive care for complications.

Conclusions:

• Autoimmune encephalitis requires specialized, multidisciplinary care in acute and intensive settings.
• Timely diagnosis and treatment are critical for improving prognosis and reducing long-term sequelae.
• Further research into AE management and critical care complications is essential.
