How autoimmunity changed our diagnostic practice in epileptology?

Area of Science:

• Neurology
• Immunology
• Epileptology

Background:

• Autoimmunity is recognized as a key etiology of epilepsy.
• Autoimmune epilepsy (AE) presents as either acute symptomatic seizures (ASS) or autoimmune-associated epilepsy (AAE).
• Distinguishing ASS and AAE is crucial due to differing prognoses and treatment responses.

Purpose of the Study:

• To highlight the growing importance of autoimmune epilepsy as a distinct neurological disorder.
• To emphasize the need for clinical tools to identify patients at high risk for positive antibody testing.
• To discuss the potential for targeted therapies in autoimmune epilepsy.

Main Methods:

• Review of current understanding of autoimmune epilepsy based on ILAE classification.
• Analysis of clinical presentations differentiating ASS and AAE.
• Discussion on the diagnostic challenges and therapeutic implications.

Main Results:

• Autoimmune epilepsy is a distinct cause of seizures, classified as ASS or AAE.
• Patients with isolated seizures pose a diagnostic challenge, potentially indicating either ASS or AAE.
• Clinical scores are needed to guide antibody testing and immunotherapy decisions, especially in non-encephalitic cases.

Conclusions:

• Early identification of autoimmune epilepsy is critical for optimal patient outcomes.
• Development of predictive clinical scores is essential for timely diagnosis and treatment.
• Targeted immunotherapies represent a promising frontier for managing and potentially curing autoimmune epilepsy.
