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.
Symptoms of increased intracranial pressure – such as headache and vomiting – should be questioned after. [32] [33] An elevation of ICP can be present in 4 to 20% of the children where only a single suture is affected. [32] [33] The incidence of ICP in children with more than one suture involved can be as high as 62%. [56]
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.
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.

Increased intracranial pressure (ICP) is a life-threatening surgical emergency marked by symptoms of headache, nausea, vomiting, decreased consciousness. [1] Symptoms are frequently accompanied by visual disturbances such as gaze paresis , reduced vision, and dizziness. [ 1 ]
A pilot study of Frank and colleagues that evaluated different modalities of OAE in 12 healthy volunteers and 5 patients with implanted ventricular catheters for direct ICP monitoring revealed that increased ICP or conditions known to increase ICP (e.g. posture changes, abdomen compression, coughing) were associated with notable decreases ...
A Cushing ulcer, named after Harvey Cushing, [1] [2] is a gastric ulcer associated with elevated intracranial pressure. It is also called von Rokitansky –Cushing syndrome. [ 2 ] Apart from the stomach , ulcers may also develop in the proximal duodenum and distal esophagus .
The treatment depends largely on the underlying cause. However, the root cause of papilledema is the increased intracranial pressure (ICP). This is a dangerous sign, indicative of a brain tumor, CNS inflammation or idiopathic intracranial hypertension (IIH) that may become manifest in the near future.
