The Treatment of Trigeminal Autonomic Cephalalgias: An Overview

Area of Science:

• Neurology
• Headache Medicine

Background:

• Trigeminal autonomic cephalalgias (TACs) encompass a group of primary headaches including cluster headache (CH), paroxysmal hemicrania (PH), and short-lasting unilateral neuralgiform headache attacks (SUNHAs).
• Hemicrania continua (HC) shares clinical and pathophysiologic features with TACs.
• While rare, CH is the most prevalent TAC, affecting approximately 1 in 1,000 individuals.

Purpose of the Study:

• To review current treatments for TACs based on recent guidelines.
• To explore emerging therapeutic options for these challenging headache disorders.

Main Methods:

• Review of existing literature and guidelines on TAC treatments.
• Analysis of evidence from open studies, case series, and single-case observations due to limited randomized controlled trials.
• Inclusion of data on novel drug administration, pericranial interventions, and neurostimulation.

Main Results:

• Current treatment strategies for TACs are discussed.
• Promising results are emerging from novel drug delivery systems, invasive pericranial procedures, and neurostimulation techniques.
• Ongoing research is exploring future treatment avenues.

Conclusions:

• Effective management of TACs relies on current guideline-based treatments.
• Novel therapeutic approaches, including drug administration, interventions, and neurostimulation, show promise.
• Further research is essential to develop and validate new treatments for TACs.
