The role of emotional and behavioral disorders in the development of drug dependence in patients with medication-induced headache (review)
Medication-induced headache (MIH) is a variety of chronic daily headache (HA). MIH belongs to secondary (symptomatic) HA, develops as a complication of pre-existing primary cephalgia, and is caused by the overuse of drugs to relieve HA. The role of drug dependence syndrome and behavioral and emotional disorders in the development of MIH, which may be associated with dysfunction of certain brain systems that control these functions, has been recently discussed. The paper reviews the literature dealing with studies of the role of behavioral and emotional disorders and orbitofrontal cortical dysfunction in the development of drug dependence syndrome in patients with MIH. The importance of analyzing these aspects of MIH is determined by the prospects for applying alternative approaches to managing these patients.
