Autoimmune Encephalitis: A Physician's Guide to the Clinical Spectrum Diagnosis and Management

Area of Science:

• Neuroscience
• Immunology
• Neurology

Background:

• Autoimmune encephalitis (AE) spectrum has expanded due to new neuronal autoantibody discoveries.
• Diagnosis is challenging due to diverse clinical presentations, psychiatric mimicry, and non-specific imaging/EEG findings.
• A subgroup of patients lack detectable IgG autoantibodies in blood or CSF.

Purpose of the Study:

• To provide primary care physicians and hospitalists with an evidence-based approach to diagnosing and managing autoimmune encephalitis.
• To update clinicians on the latest data regarding new-onset neuropsychiatric symptoms of suspected autoimmune origin.
• To facilitate early recognition and treatment for improved patient outcomes.

Main Methods:

• This is a review article, synthesizing current evidence on autoimmune encephalitis.
• It focuses on diagnostic challenges and management strategies.
• The review targets non-neurologists who are often the first point of contact.

Main Results:

• The review highlights the diagnostic difficulties in autoimmune encephalitis.
• It emphasizes the importance of considering autoimmune etiologies in new-onset neuropsychiatric disorders.
• It underscores the need for timely intervention to improve recovery.

Conclusions:

• Early diagnosis and treatment of autoimmune encephalitis are critical for better outcomes.
• This review equips primary care physicians and hospitalists to manage suspected autoimmune neurological disorders.
• Prompt management can lead to complete recovery and prevent long-term disability.
