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, and shoulder pain.
Drug-induced intracranial hypertension (DIIH) or medication-induced intracranial hypertension is a condition of higher than normal intracranial pressure with the main cause being a drug. [15] This condition is similar to idiopathic intracranial hypertension , however the etiology in this instance is a drug. [ 16 ]
Idiopathic intracranial hypertension, or unexplained high pressure in the cranium, is a rare condition that can cause visual impairment, frequent severe headache, and tinnitus. It is most commonly seen in obese women, and the incidence of idiopathic intracranial hypertension is increasing along with increases in the number of people who are obese.
In terms of environmental factors, dietary salt intake is the leading risk factor in the development of hypertension. [7] Salt sensitivity is characterized by an increase in blood pressure with an increase in dietary salt and is associated with various genetic, demographic, and physiological factors— African American populations, postmenopausal women, and older individuals carry a higher ...
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]
The majority of patented methods for noninvasive monitoring of ICP are based on an assumption that changes in ICP affect the physical dimensions and/or acoustic properties of the cranial vault or intracranial structures (dura, brain tissue, brain ventricles, and/or intracranial vessels).
Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis. [5] Atherosclerosis narrows blood vessels in the brain, resulting in decreased cerebral perfusion.
Environmental and occupational risk factors are increasingly being associated with diseases classified as idiopathic. Emerging evidence indicates a complex relationship between intrinsic ( genetic ) and extrinsic (environmental and occupational risk factors) factors in disease physiopathology.
