A型肉毒毒素治疗慢性偏头痛的专家共识OA

Migraine,with its high prevalence,ranks as the second leading cause of disability among neurological disorders.Chronic migraine,in particular,imposes a greater disease burden,leads to poorer quality of life for patients,and results in higher healthcare resource consumption.Current conventional oral preventive medications often suffer from inadequate efficacy,poor tolerability,and potential drug-drug interactions,which can contribute to the persistence of headaches.This makes chronic migraine a significant clinical challenge and public health issue.Botulinum toxin type A injection has gained widespread attention as an effective preventive treatment for chronic migraine.This expert consensus is developed based on domestic and international advances in diagnosis and treatment,combined with the actual situation in China,with the aim of guiding neurologists and other relevant clinicians in the standardized use of botulinum toxin type A for the management of chronic migraine.
