There might be a medical reason for it, so see a doctor to be safe.

There are any number of things it could be, a trapped or compressed nerve comes to mind first.  You need to have it checked out, better safe than sorry.

this is the best i found!\ninteresting discussions.\nApparently, the brain is short of oxygen and looses its functional ability.what really happens: you will have to check out the websites and see!\nthe first link takes you to other various links on this matter.\nthe second link gives detailed diagrams with explanations.

Anything near or having to do with the brain is serious and being that i'm not a doctor, I don't want to scare you or tell you about something, I know nothing about. I suggest you ask your doctor, or have your doctor refer you to someone, that specializes, in that type of profession.

The ventricles are larger. Why this makes a difference is unknown.

I hope that the answer is as simple as an inner ear infection, but the chances are it could be more serious.  My friend's son was vomiting every day at approximately the same time and after extensive tests they found a tumor in his head.  Everything has worked out fine and the little boy is doing well.  But I think that our bodies are amazing at letting us know when there is something wrong.  I am glad that she has a doctors appointment tomorrow.

The brain completly controls the human body, It depends on the part of the brain damaged by the tumaor, for example damage to the cerebellum could cause cerebal palsy or complete paralysis. damage to the midulla oblongatta could prevent functioning of autonomic functions and require life support.

yes, my daughter has suffered with this since she was 6, for 7 years medication controlled the seizures, and for the last 3, for no apparent reason, the medication has lost much of it's effectiveness, even though she has been on several. she has had 3 mri's, a pet scan, and ct's, which all show nothing abnormal. however, the eeg, and video eeg all show a right side focus, but cannot pinpoint where or why it happens. it could be something organic in her brain to begin with, or possibly hereditary, as my niece has also had seizures. it can be very frustrating when there is no apparent reason for the seizures, be it something organic or an injury. i'm sure by now you have seen a neurologist, and if it is an ongoing thing, i would discuss medication with him, and the medication is effective in 98% of people with epilepsy. good luck, the best thing is to be there for her, and help her through this.

Becuz all the blood is rushing toward your brain, causing it to swell.\nThe blood is also not getting to your heart.

CT\n\nIf you suspect a lesion in the posterior fossa or brainstem, CT is usually not even considered.  Go straight to MRI.  Something about "beam hardening" artifact that occurs when trying to image the posterior fossa with CT....

the ventricles of the brain hav cerebrospinal fluid in them.

I just passed my four year anniversary for the removal of my 4 x 7 cm left frontal meningioma. It was pushing the left side of my brain into the right. That first MRI was a scary one.\n\nTwo years ago, I was faded off dilantin/zonegran on the same slow and steady rate without problem. I hadn't had a seizure, but scans showed "abnormal activity" that could be seizure related. My neurologist said after surgery for a brain tumor you'd expect there to be some "abnormal activity".  Dilantin made me so tired it was great being free from it. \n\nGood Luck, there are more of us out there than you think.

1)  The hormone is growth hormone (GH) , pressure in the head is caused by increased skull thickness, which is a result of the pituitary tumor secreating too much GH.  The visual disturbances are caused by the enlarged pituitary (from the tumor) compressing the optic chiasm.  \n\n2) So hypothalymus hormones can go directly to the anterior pituitary (rapido action as dr. guru pattar says) without circulating throughout the whole body.

You should ask the doctor or surgeon treating the patient.  I wouldn't even guess unless you told me what part of the brain was damaged.

There could be any number of reasons for this, from the physical to the physiological to the psychological.  Please please PLEASE go see your doctor as soon as possible.
