Abstract:
Cluster Headache (CH) is cited as one of the most painful experiences known to humankind. This thesis portfolio aimed to provide a greater insight into the psychological aspects of CH. A systematic review accumulated evidence of rates of depression and suicidality in individuals living with CH and an empirical paper explored the psychological experience of living with CH.

A systematic review and meta-analysis was conducted to determine rates of depression and suicidality amongst individuals with CH compared to non-headache controls and individuals with other primary headache conditions (Migraine or Tension-Type Headache (TTH)). Secondly, 13 interviews were conducted with individuals living with CH and this data was analysed using Reflexive Thematic Analysis.

Meta-analyses of 20 studies showed that compared to non-headache controls, adults with CH had much higher levels of depression and suicidality. However, there was no significant difference in depression levels between CH and Migraine individuals. Comparing individuals with CH and TTH, the initial meta-analysis found no significant difference in depression levels, but a sensitivity analysis showed TTH individuals having higher levels of depression. Considerable heterogeneity and publication bias were present. Reflective Thematic Analysis identified five themes relevant to the CH experience: “Darkness”, “Battling”, “Shifting”, “Control”, and “Despair”. There were differences within these themes based on whether a person was in the moment of pain or between attacks, whether they had the chronic or episodic form of CH, and how long they had lived with CH.

This portfolio highlighted that psychological aspects of CH include increased depression and suicidality. Increased depression was also present for the other primary headache disorders. The empirical paper identified various psychological processes important in the experience of CH which could be the target of psychological treatment.
