Navigating the waves of cluster headache

Summary

Cluster headache is characterized by recurring 'waves' of attacks. Long-term remission is linked to episodic disease, later onset age, more painful attacks, and smoking cessation, suggesting smoking may play a role in disease development. People with cluster headache more often use psilocybin and LSD, with some reporting reduced attack frequency or duration. Risk-taking behavior is increased in episodic but reduced in chronic disease, indicating adaptive changes. Testosterone deficiency is more prevalent, especially in chronic cases, likely originating in the brain. A Dutch version of the Cluster Headache Quality of Life questionnaire was developed; quality of life is more strongly tied to mental health and activity limitations than attack frequency alone. Greater occipital nerve infiltration is clinically effective, but its mechanism remains unresolved.

Abstract

This dissertation explored the factors underlying the “waves” of cluster headache and investigated strategies to reduce disease burden and improve quality of life. The first part focused on disease mechanisms, prognosis, and patient experiences. Long-term remission was associated with episodic disease, later onset age, more painful attacks, and smoking cessation, suggesting a multifactorial process and a possible role of smoking in disease development. Studies on illicit drug use showed that people with cluster headache more often used substances such as psilocybin and LSD, with some reporting reduced attack frequency or duration. Risk-taking behavior appeared increased in episodic cluster headache but reduced in chronic disease, suggesting adaptive changes over time. Hormonal studies demonstrated an increased prevalence of testosterone deficiency, particularly in chronic cluster headache, likely originating centrally in the brain. To better assess disease burden, a Dutch version of the Cluster Headache Quality of Life questionnaire (CHQ-D) was developed and validated. Quality of life was more strongly associated with mental health and activity limitations than with attack frequency alone. The second part investigated greater occipital nerve (GON) infiltration as a preventive treatment. Although clinically effective, neurophysiological studies found no evidence that symptom relief was mediated through altered trigeminal conduction, leaving the mechanism unresolved.
