Intracranial pressur: Intracranial pressure is measured typically by two ways. One is bur hole in the head with a catheter or monitor wire placed into the brain and attached to a monitor and read over 24 hours. The other is a spinal tap in the lower spine and a direct measurement of the opening pressure when the needle is placed into the spinal space. ...Read more

In what way can intracranial pressure(csf) be reduced?

In what way can intracranial pressure(csf) be reduced?

Intracranial pressur: Reducing intracranial pressure is really based on what is causing the pressure. In some cases a spinal tap can be done, there are medications available that can reduce fluid pressure and if do to an obstruction then a tube can be place (a shunt) to bypass the obstruction. ...Read more

HA & papilledema: Headache, and papilledema or elevated edematous optic nerve are the first signs of increased intracranial pressure. 95% of cases are pseudo-tumor cerebri or idiopathic intracranial hypertension, or "glaucoma of brain" same medication treats it. If in doubt we get the neurosurgeon to do a spinal tap. Real tumors are rare and usually have local signs, like dr. Chen has mentioned. ...Read more

Why the increasing in the intracranial pressure causing bradycardia?

Parasympathetic resp: Part Cushing Triad/reflex: Caused by the increased intracranial pressure (ICP) that initially increases heart rate and cardiac output to improve cerebral ischemia but then the aortic barorreceoptors detect it and trigger a parasympathetic response via the Vagus nerve (second phase of Cushing response). Direct distortion of the Vagus by elevated ICP can also trigger bradycardia directly. ...Read more
