Personality traits, personality disorders, and migraine: a review

The personality trait of neuroticism has been associated with migraine, although research is needed to clarify potential moderators of this relationship and the extent to which neuroticism reflects a stable disposition or instead is a function of general somatic distress or situational influences. With the possible exception of harm avoidance, research has not consistently identified any other personality trait unique among migraineurs. Personality disorders have been researched less extensively, but existing data suggests that borderline personality disorder, in particular, is associated with increased negative impact of migraine, risk for medication overuse, and poor response to treatment that is likely of greater clinical importance than any personality trait per se.
