Classification of two phenotypically distinct headache disorders

Takeaway

  • Due to the absence of major clinical differences between short-lasting unilateral neuralgiform headache attacks with autonomic features (SUNA) and short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT), the authors propose that the two disorders are unified in a single diagnostic category.

Why this matters

  • SUNCT and SUNA could be considered a single clinical entity under the name SUNA, as this terminology highlights the occurrence of a wide spectrum of cranial autonomic features beyond conjunctival injection and lacrimation.
