Summary

Hypertension and neurologic diseases have an intricate relationship. In the cerebrovascular diseases, many of them are caused by long-standing hypertension, however, in the acute period, the brain demands elevated blood pressures to maintain its functioning. In some inflammatory disorders of the brain, an abrupt increase in blood pressures can cause significant damage to the brain, however, as in cerebrovascular diseases, careful lowering of blood pressures is required to allow the brain to maintain a status quo in the acute period. This chapter will enlighten the reader on the pathophysiology of blood pressure and cerebral blood flow – the basics for understanding how to manage blood pressure in neurologic emergencies. A brief discussion on antihypertensive agents will follow, with the remaining chapter discussing blood pressure management tailored to common neurologic diseases presenting with hypertensive crises.
