Peripheral and Central Mechanisms in Tension-Type Headache: an Update

Abstract

Despite the tremendous socoeconomic impact of tension-type headache surprisingly little is known about the underlying pathophysiology and treatment. Existing evidence and theories about the relation between central and peripheral mechanisms are discussed. Central sensitization is probably the most important key to understand this widespread disorder. An effective prevention or reversal of this central sensitization will probably be of major importance in future treatment strategies.
