Abstract
Purpose of Review
Provide an overview of the current diagnosis, pathophysiology, and treatment of Susac’s syndrome (SuS), with special emphasis on summarizing what is currently known about headache as a symptom of disease activity.
Recent Findings
The most recent literature in SuS has focused on furthering the understanding of the underlying pathology and efficacy of treatments for SuS. The importance of early recognition to facilitate timely treatment and avoid long-term disability has been highlighted. Headache, the most common symptom experienced by patients with SuS, can occur up to 6 months in advance of other symptoms, and exacerbations of headache can herald increased disease activity.
Summary
Susac’s syndrome (SuS) is a rare disorder classically characterized by triad of encephalopathy, branch retinal artery occlusion (BRAO), and sensory neuronal hearing loss (SNHL). The full triad is uncommon at initial presentation, which can confound efforts to make timely diagnosis and treatment decisions. Headache is the most common symptom in SuS, is often an early feature, and can help separate SuS from other diagnoses in the differential. However, the features and management of the headache associated with SuS have not been systematically defined in the literature.

Egan RA. Diagnostic criteria and treatment algorithm for Susac syndrome. J Neuroophthalmol. 2019;39(1):60–7 This article builds on the diagnostic criteria published by Kleffner et al. [ref 13], suggesting that there are 2 findings that allow for the diagnosis of definite Susac syndrome even when the clinical triad is not fully present, which might allow for earlier diagnosis and therefore earlier treatment.
