	INTRACRANIAL PRESSURE
		Normal intracranial pressure in adults is 8 to 18mm Hg and in babies the pressure is 10-20mm less when measured through a lumbar puncture.
		There is a rise with cardiac systole (due to distention of intracranial arteriolar tree which follows) and a slower change in pressure with respiration, falling with each inspiration and rising with expiration.
		Intracranial pressure is a result of at least 2 factors, the volume of the brain (about 1400ml in an adult) being constant.

		It is believed that intracranial pressure is a reflection of the atmospheric pressure which is conducted through the large neck vessels.
		Accurate measurement of pressure in new born and infants is difficult to obtain but it is believed that in the first few months of life the intracranial pressure is lower.
		The most accurate method of measuring the intracranial pressure is by the use of electrodes with a sensor attached to its tip.

	Brain Tumor \| CancerBiopsies
		Large tumors or tumors with extensive perifocal swelling edema inevitably lead to elevated intracranial pressure (intracranial hypertension), which translates clinically into headaches, vomiting (sometimes without nausea), altered state of consciousness (somnolence, coma), dilatation of the pupil on the side of the lesion (anisocoria), papilledema (prominent optic disc at the funduscopic examination).
		In young children, elevated intracranial pressure may cause an increase in the diameter of the skull and bulging of the fontanelles.
		A bilateral temporal visual field defect (bitemporal hemianopia—due to compression of the optic chiasm), often associated with endocrine disfunction—either hypopituitarism or hyperproduction of pituitary hormones and hyperprolactinemia is suggestive of a pituitary tumor.

	Discovery Health :: Diseases & Conditions :: increased intracranial pressure
		Increased intracranial pressure (ICP) means that the pressure inside the skull is abnormally high, which may cause damage to the brain.
		Therefore, even a moderately increased pressure in the skull squeezes the brain and decrease blood flow to the brain cells.
		This is because if such a lesion is present, a spinal tap will create a pressure difference between the brain and spinal canal that could lead to protrusion of the brain stem through the base of the skull, a fatal outcome.

		It can also be due to increased pressure within the brain matter caused by lesions (such as a tumor) or swelling within the brain matter itself.
		The pressure itself can be responsible for further damage to the central nervous system by causing compression of important brain structures and by restricting blood flow through blood vessels that supply the brain.

	brain injury .com \| What is Intracranial Pressure (ICP)?
		The problem with increased ICP is that the fluid under pressure tends to deform the brain itself and pushes tissue in such a way as to cause injury to the brain itself.
		The results of increased pressure can often be seen in cases of a “slow bleed.” In cases like this, often involving either children who are unable to respond or older patients, a fall or other type of injury will occur, sometimes without even loss of consciousness.
		Often, the results of the subjection to pressure on the brain are not able to be visualized on MRI for several weeks following the pressure.

	(Industry News) Wireless Implant Measures Intracranial Pressure
		The condition is often treated with shunts—thin silicone tubes that drain excess cerebrospinal fluid into a body cavity, where it is absorbed.
		Small enough to be used for infants afflicted with the disease, the sensor is placed directly under the cranial bone by means of minimally invasive surgery.
		The implant is an alternative to intraventricular catheters, which measure and stabilize elevated intracranial pressure simultaneously, but the catheters are invasive and can only remain in the brain for a limited time.

	BioMed Central \| Abstract \| Short-term elevation of intracranial pressure does neither influence duodenal motility nor ...
		Patients with traumatic brain injuries and raised intracranial pressure (ICP) display biphasic response with faster gastric emptying during the early stage followed by a prolonged gastric transit time later.
		Duodenal luminal lactate, pyruvate, and glucose concentrations were measured during physiological state and during elevated intracranial pressure of 10, 20, 30, 40, and 50 mmHg in six pigs.
		The present study suggests that a stepwise and hourly increase of the intracranial pressure of up to 50 mmHg, does not influence duodenal motility activity in a significant manner.

	Intracranial Pressure and Cerebral Blood Flow (page 1)
		Maintenance of cerebral blood flow depends on a balance between the pressure within the skull, intracranial pressure (ICP) and the arterial pressure of the blood, mean arterial pressure (MAP).
		Similarly, when blood pressure rises, the same mechanism stops the blood flow from increasing to excessive levels.
		ICP intracranial pressure is the pressure within the rigid skull.
