Hypertension And Its Relation To Headache And Other Craniofacial Neuralgiform Pain
Published 2018 · Medicine
Patients who suffer from headache are anxious to know the cause of their headache. Majority of the patients relate their headache to either a refractory error or high blood pressure. However, despite correction of hypertension and the refractory error, they continue to have headaches. The relationship of headache with hypertension has interested the headache specialists for nearly one century. T.C. Janeway first suggested the causal relationship of hypertension to headache in 1913. However, the relationship of headache with hypertension does not appear to be linear. There are many unanswered questions. Can mild-to-moderate hypertension produce headache? Does headache produce high blood pressure? Can acute rise in blood pressure produce headache? Is headache related to chronic hypertension? Is headache an invariable symptom in conditions associated with acute hypertension such as pheochromocytoma, eclampsia, and preeclampsia? Is headache a symptom of hypertensive encephalopathy or malignant hypertension? What is the possible mechanism of a hypertensive headache? Are there any specific headache characteristics that can be attributed to hypertensive headache? These are some of the questions that the researchers have tried to answer in the last century. In this review, we will take up individual case scenarios and try to address some of these questions.
