Question 1

why does increased intracranial pressure cause projectile vomiting?

Accepted Answer

Not sure: Increased pressure in the brain/skull is often associated with vomiting.   We don't know exactly how the pressure triggers the vomiting center in the brainstem, it just does. Since sudden onset of headache and vomiting can be a sign of a serious condition see you doctor immediately. This is especially true if the vomiting occurs during the night while sleeping.

Question 2

will fludrocortisone 0.1mg cause a lot of increased intracranial pressure? just wondered.

Accepted Answer

Preesure: Yes it could cause increased intracranial pressure.

Question 3

could brain tumors always cause increased intracranial pressure?

Accepted Answer

It depends on size: There is limited space inside the skull. So any space occupying lesion causes rise in intracranial pressure once it gets to a size above 1 or 2 cms.

Question 4

if someone has increased intracranial pressure and starts taking doxycycline, will the doxycycline cause the intracranial pressure to increase even further? or is it not certain that this would happen?

Accepted Answer

: No, you can take if there is an absolute indication.

Question 5

why does hypertension cause increased intracranial pressure?

Accepted Answer

No it does not: Increase intracranial Pressure is the increase pressure inside the skull and thereby in the cerebrospinal fluid and brain itself.
But it is not caused by Systemic Hypertension

Question 6

when a benign brain tumor causes increased intracranial pressure, would doxycycline further increase the pressure?

Accepted Answer

: Doxycycline is not commonly used to decrease intracranial pressure or known to have this effect. Moreover, there have been described cases of tetracyclines as doxycycline increasing intracranial pressure. Would suggest discussing above concerns with prescribing physician.

Question 7

can bilateral mydriasis indicate increased intracranial pressure? both my pupils react evenly, but my doctor was still surprised at this.

Accepted Answer

Mydriasis: Or pupil dilation is quite common in younger people.  They tend to have naturally larger pupils.  As long as they are equal and both react well, then this is totally normal.  On the other hand, an increase in intracranial pressure can cause one or both pupils to dilate but typically they don't react well in this situation.

Question 8

if increased intracranial pressure(icp) is contraindicated in lumbar puncture, why one of the indication of this procedure is to decrease the icp?

Accepted Answer

Depends: Lp is contraindicated when the icp is due to some process that is creating a midline shift in the brain and sudden loss of pressure can cause herniation of the midbrain and consequent death.  You can reduce some icp with LP but better to place intraventricular drain and then decide whether permanent shunt may be necessary.

Question 9

why is a person with increased intracranial pressure  given the diuretic mannitol?

Accepted Answer

Mannitol: Mannitol works to reduce intracranial pressure through its diuretic properties.  It is usually used in the acute setting (after head trauma).

Question 10

can you get increased intracranial pressure 2 years later from a concussion where you didnt go unconscious?

Accepted Answer

A remote: possibility is an obstruction of the fluid outlet by an adjacent small blood clot......Just a guess but I would certainly ask about it!

Hope this is helpful!
