Childhood Chronic Recurrent Headache in Hong Kong: A Case Control Study

KL Cheung, WW Cheng, KYY Ng, CH Ko


Childhood headache is commonly encountered in paediatric practice and can lead to significant morbidities. Local research and management consensus is lacking. This is a case control study conducted on children with primary functional headaches from a specialist outpatient clinic utilising a structured questionnaire. Headaches were classified as migraine, tension headache and nonspecific headache, according to the International Headache Society criteria. We ascertained the pattern of distribution of various functional headaches, pain characteristics, interventions and psychosocial impacts on the child and family. Subjects with migraine were compared with those with tension and nonspecific headaches, which were grouped into non-migrainous headache. The findings were appraised with reference to local and overseas literatures from adult and paediatric practices. Forty-eight consecutive subjects were recruited, in which 58.3% were diagnosed to have migraine and 41.7% with non-migrainous headache. Characteristics of childhood headaches manifest differently in children compared to adults. A high incidence of unnecessary neuroimaging and psychosocial impairment warrants overhaul of local practice in refractory headaches. Impairment in social function was found to be common in both groups.
