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.
Intracranial hypertension (IH), also called increased ICP (IICP) or raised intracranial pressure (RICP), refers to elevated pressure in the cranium. 20–25 mmHg is the upper limit of normal at which treatment is necessary, though it is common to use 15 mmHg as the threshold for beginning treatment.
The non-invasive ICP meter based on this method gradually increases the pressure over the eyeball and intraorbital tissues so that the blood flow pulsation parameters in two sections of the OA are equal. At this pressure balance point, the applied external pressure (Pe) equals the intracranial pressure (ICP). This measurement method eliminates ...
Papilledema or papilloedema is optic disc swelling that is caused by increased intracranial pressure due to any cause. [ 1 ] The swelling is usually bilateral and can occur over a period of hours to weeks. [ 2 ] Unilateral presentation is extremely rare. In intracranial hypertension, the optic disc swelling most commonly occurs bilaterally.
Intracranial hemorrhage is a serious medical emergency because the buildup of blood within the skull can lead to increases in intracranial pressure, which can crush delicate brain tissue or limit its blood supply. Severe increases in intracranial pressure (ICP) can cause brain herniation, in which parts of the brain are squeezed past structures ...
Manage abnormal hormone levels [1] Empty sella syndrome is the condition when the pituitary gland shrinks or becomes flattened, filling the sella turcica with cerebrospinal fluid instead of the normal pituitary. [2] It can be discovered as part of the diagnostic workup of pituitary disorders, or as an incidental finding when imaging the brain.
Cerebrovascular disease. Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. Arteries supplying oxygen and nutrients to the brain are often damaged or deformed in these disorders. [2] The most common presentation of cerebrovascular disease is an ischemic ...
Intracranial hypertension can also be caused by cysticercotic encephalitis, which is a severe type of neurocysticercosis usually affecting younger women and children. [3] Cysticercotic encephalitis is characterized by seizures, intracranial hypertension, clouding of consciousness, papilledema , headache, reduction of visual acuity , and vomiting .
