SUNCT/SUNA: A Review

Area of Science:

• Neurology
• Headache Medicine

Background:

• Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting neuralgiform headache attacks with cranial autonomic features (SUNA) are rare, severe headache disorders.
• These conditions are frequently refractory to standard treatments and can present as secondary symptoms.

Purpose of the Study:

• To provide a comprehensive review of the history, pathophysiology, and treatment of SUNCT and SUNA.
• To discuss both established and emerging therapeutic strategies for these challenging headache disorders.

Main Methods:

• Literature review encompassing historical data and recent reports on SUNCT and SUNA.
• Analysis of pharmacotherapy and procedural interventions for managing these conditions.

Main Results:

• The review covers the evolution of understanding and treatment approaches for SUNCT and SUNA.
• It highlights the challenges in managing these rare headache types due to their refractory nature.

Conclusions:

• Effective management of SUNCT and SUNA requires a thorough understanding of their pathophysiology and a tailored approach to treatment.
• Both pharmacological and interventional strategies play a role, with ongoing research needed to improve outcomes.
