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.
Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia.

Decompressive craniectomy is frequently performed in cases of resistant intracranial hypertension secondary to several neurological conditions and is commonly followed by cranioplasty. [15] Complications, such as infection and hematomas after cranioplasty occur in roughly about a third of cases. [15]
Intracranial hypertension will thus manifest in an increased diameter of the optic nerve sheath and will impede the blood flow through the central retinal vein that courses within the sheath, along and in part inside of the optical nerve.
Lumbar–peritoneal shunts are used in neurological disorders, in cases of chronic increased intracranial pressure to drain excess cerebrospinal fluid (CSF) from the Subarachnoid cavity associated with such conditions as hydrocephalus and Benign intracranial hypertension (BIH) also known as idiopathic intracranial hypertension (IIH) and ...

Cranial CSF leaks result from intracranial hypertension in the vast majority of cases. The increased pressure causes a rupture of the cranial dura mater, leading to a CSF leak and intracranial hypotension. [46] [47] Patients with a nude nerve root, where the root sleeve is absent, are at increased risk for developing recurrent CSF leaks. [48]
