Theory of mind: a new perspective on cluster headache-a cross-sectional study.

Introduction: Theory of mind (ToM) is the ability to attribute mental states of self and others, such as beliefs (cognitive ToM) and feelings (affective ToM). Based on the role of the hypothalamus in pain and social cognition, our aim is to determine whether ToM is impaired in patients with cluster headache (CH).

Methods: Cross-sectional study in which 31 episodic cluster headache (ECH) patients outside the bout and 20 matched controls carried out social cognition and executive function tasks.
