High blood pressure crisis and headaches. If your blood pressure is 180/120 mm Hg or higher and you have chest pain, back pain, or vision changes, you may be having a hypertensive emergency ...
The impairment of cerebral blood flow that underlies hypertensive encephalopathy is still controversial. Normally, cerebral blood flow is maintained by an autoregulation mechanism that dilates arterioles in response to blood pressure decreases and constricts arterioles in response to blood pressure increases. This autoregulation falters when ...
A hypertensive emergency is not based solely on an absolute level of blood pressure, but also on a patient's baseline blood pressure before the hypertensive crisis occurs. Individuals with a history of chronic hypertension may not tolerate a "normal" blood pressure, and can therefore present symptomatically with hypotension , including fatigue ...

[1] A clinician may recommend rest and the avoidance of activities or vasoactive drugs which trigger symptoms (see § Causes). [1] Analgesics and anticonvulsants can help manage pain and seizures, respectively. [1]
A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
