SUN: Short-Lasting Unilateral Neuralgiform Headache Attacks

Area of Science:

• Neurology
• Headache Medicine
• Pain Management

Background:

• Short-lasting unilateral neuralgiform headache attacks (SUN) are classified under trigeminal autonomic cephalalgias (TACs).
• SUN attacks are characterized by unilateral head pain accompanied by ipsilateral cranial autonomic symptoms.
• Recent classification changes accommodate diverse autonomic symptom presentations.

Purpose of the Study:

• To review the clinical features of SUN attacks.
• To discuss the pathophysiology underlying SUN.
• To explore current and emerging therapeutic strategies for SUN.

Main Methods:

• Literature review of clinical studies and case reports on SUN.
• Analysis of recent updates in TAC classification.
• Synthesis of data on treatment efficacy and future directions.

Main Results:

• SUN syndrome diagnosis is evolving with updated classifications.
• Increased recognition of SUN syndrome and its treatment landscape.
• Diverse therapeutic options are becoming available for managing SUN.

Conclusions:

• SUN is a distinct entity within TACs, requiring specific diagnostic and therapeutic approaches.
• Understanding the pathophysiology is key to developing novel treatments.
• Ongoing research promises improved management for patients with SUN.
