Childhood emotional abuse fuels odds for migraine in adulthood

Emotionally abused children are 52% more likely to develop migraine in young adulthood than are those who were never abused, based on longitudinal survey data from nearly 15,000 individuals.

“Childhood maltreatment, and especially emotional abuse, is a common, likely under-recognized occurrence, which has enduring consequences for health throughout life. The association of emotional abuse with migraine has not heretofore been well studied, being the subject of only population-based study,” lead author Dr. Gretchen E. Tietjen of the University of Toledo (Ohio) said in an interview in advance of the presentation of the study at the annual meeting of the American Academy of Neurology in Vancouver in April.

Dr. Tietjen and her colleagues assessed data from 14,484 adults aged 24-32 years who took part in wave four of the National Longitudinal Study of Adolescent to Adult Health. Of these, 2,061 (14%) reported a migraine diagnosis, and 1,246 (60%) of those diagnosed with migraines reported some type of childhood abuse. A total of 6,088 (49%) individuals without migraine reported some type of childhood abuse.

Overall, the odds of migraine in adulthood was 55% higher in children who reported emotional abuse, physical abuse, or sexual abuse, compared with those who reported no childhood abuse, after controlling for age, race, sex, and income (odds ratio, 1.55; 95% confidence interval, 1.35-1.77). However, only emotional abuse remained significantly associated with increased odds for migraine after controlling for other types of abuse (OR, 1.52; 95% CI, 1.34-1.73).

Emotional abuse was assessed by asking, “How often did a parent or other adult caregiver say things that really hurt your feelings or made you feel like you were not wanted or loved?” Physical abuse was defined as being hit with a fist, kicked, or thrown down on the floor, into a wall, or down stairs. Sexual abuse included forced sexual touching or sexual relations.

Controlling for depression and anxiety weakened the associations between childhood abuse overall and likelihood of migraine in young adulthood, as well as for emotional abuse in particular, but the relationships remained statistically significant (OR, 1.32 and 1.33, respectively).

Dr. Tietjen said she was surprised by the absence of an association between migraine and physical and sexual abuse after controlling for other types of abuse.

“Sexual and physical abuse may be less frequent, occur over a briefer duration, and if limited, lead in some cases to resilience,” Dr. Tietjen noted. “Emotional abuse is likely more insidious, being ingrained in the fabric of the family dynamic. It may occur over years without recognition or intervention,” she said. “This type of abuse may cause more cumulative stress, with subsequent dysregulation of the HPA axis, immune, autonomic, and metabolic systems,” she added. 

The study does not show cause and effect, the researchers noted, and more research is needed. But the findings suggest that clinicians might consider childhood abuse when counseling adult migraine patients.

“In migraineurs, childhood abuse, particularly emotional abuse, is common and possibly causally related,” Dr. Tietjen said. “Knowledge of adverse childhood experiences allows physicians to identify migraineurs at higher risk for psychiatric disease, pain comorbidities, and conditions associated with inflammation. These patients would likely benefit from exposure to cognitive behavioral therapy strategies, in order to decrease neurophysiological responses to stress,” she noted.

“There are currently therapies which reverse stress-induced epigenetic changes, which might be particularly useful in the subset of migraineurs who have been abused,” said Dr. Tietjen. Her next steps for research involve studying the effect of early life stress on factors such as pain sensitivity, anxiety, and depression.

The University of Toledo and the Clair Martig Endowment funded the study.
