Theory of Mind assessed via real life materials in Chronic Migraine with Medication Overuse.

Dataset refers to a study aimed to outline the Theory of Mind (ToM) functioning of patients with Chronic Migraine with Medication Overuse (CM+MO) compared to Episodic Migraine (EM) using the Movie for the Assessment of Social Cognition (MASC), a task consisting of the presentation of a 15-minute video clip of social interactions close to real life encounters in which participants are asked to identify and attribute mental states online. Seventy-two subjects were enrolled, of which 30 suffered from CM+MO and 42 from EM. All participants were assessed with a conventional ToM task, the Reading Mind in the Eyes test (RMET), and the MASC. We confirm impaired ToM performances in CM+MO with respect to EM when using the RMET. Interestingly, we also found that CM+MO when compared to EM were characterized by more marked deficits in the affective ToM dimension of the MASC with respect to the cognitive one and committed more hypomentalizing errors. This means that CM+MO patients may be more prone to under-interpret and misunderstand intended social interaction from another human being than the EM group. These findings have important theoretical and practical relevance in the field of CM+MO.
