Abstract
Platelet tyrosine and catecholamine (CA) content was measured in cluster headache sufferers during the different phases of the illness. Compared with controls, cluster headache sufferers had lower platelet levels of norepinephrine (NE) and epinephrine (E) in all phases of the syndrome. Tyrosine levels were increased significantly during the cluster headache attack. We suggest that these results provide biochemical evidence of sympathetic nervous system (SNS) hypofunction in cluster headache.Entities:
