Abstract
The frequent association between headache and hypertension has been recognized since the introduction of the sphygmomanometer. A cause and effect relationship proposed by early writers and widely accepted in the medical and lay community has been proposed, questioned and re-examined. The purpose of this review is to scan the literature on the subject, to present some factual data obtained from a 20 year follow-up study carried out at the Cardio-Vascular Clinic, Sydney Hospital and to summarize some personal views currently held on the relationship of hypertension and headache.
