2 per 100,000 per year [ 4] Idiopathic intracranial hypertension ( IIH ), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [ 2] The main symptoms are headache, vision problems, ringing in the ears ...
e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [ 11] High blood pressure usually does not cause symptoms itself. [ 1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
Hypertensive encephalopathy is most commonly encountered in young and middle-aged people who have hypertension. [7] [8] [9] Overall, the condition is rare even among people with hypertension. Studies report that from 0.5 to 15% of people with malignant hypertension develop hypertensive encephalopathy.
Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause. [ 1][ 2] It is the most common type affecting 85% of those with high blood pressure. [ 3][ 4] The remaining 15% is accounted for by various causes of secondary hypertension. [ 3]
Hypertensive heart disease is only one of several diseases attributable to high blood pressure. Other diseases caused by high blood pressure include ischemic heart disease, cancer, stroke, peripheral arterial disease, aneurysms and kidney disease. Hypertension increases the risk of heart failure by two or three-fold [ 7] and probably accounts ...
Hypertensive crisis. Severely elevated blood pressure (equal to or greater than 180 mmHg systolic or 120 mmHg diastolic) is referred to as a hypertensive crisis (sometimes termed malignant or accelerated hypertension), due to the high risk of complications. People with blood pressures in this range may have no symptoms, but are more likely to ...
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. Hypertension can be classified by cause as ...
