Abstract
Purpose: To estimate headache-related disability and to identify predictor of
disability in children and adolescent with headache. In addition, to assess the
improvement of disability after treatment.

Method: We conducted a retrospective analysis of clinical records of children and
adolescents who were presented with headache at the Chosun University Hospital
between January 2010 and December 2014. Headache-related disabilities were
valuated using the 6-question Pediatric Migraine Disability Assessment (PedMIDAS). The
headaches were classified according to the International Classification of Headaches
Disorders-II (ICHD-II).

Results: A total of 307 patients were identified : 117 boys and 190 girls with a mean age
of 11.3 years (range 6-18 years). About 17% of patients had a grade III-IV disability. There
is a trend towards more severe disabilities in older age groups, especially in the 16-18
year-olds. The migraine patients have the highest PedMIDAS scores (19.9¡¾26.6), whereas,
the other headache patients have the lowest scores (7.9¡¾16.0). This is higher score and
severe disability at home activity (3.5¡¾7.4) than school (2.4¡¾4.2) and play, social or leisure
activity (2.9¡¾7.7). The predictors of disability due to headache are migraine, frequent
headache and longer duration of symptom before presentation. Mean PedMIDAS score
is significantly improved by treatment (P=0.002).

Conclusion: A considerable number of children and adolescents with headache
had a moderate to severe disability. The migraine patients have the worst disability.
This study demonstrated that migraine, frequent headache and longer duration of
symptom before presentation are the predictors of headache-related disability and
a proper preventive treatment can improve the quality of life of pediatric headache
patients.
