Brain Cavities

Posted By Michelle on October 28, 1998 at 23:21:38:







I have many concerns about my 93 year old grandmother.  She has suffered with neuralgia for about the last 3 years
She recently began complaining of "hearing crickets" in her head and also describes hearing a sound much like "rocks rolling around inside her head"
if she moves her head to the side.  She has also begun to stumble when she stands up from a sitting or declining position.  She had an MRI a week ago that showed the nerve in the
face is not damaged, but her doctor did mention that the normal cavities in her brain that should contain fluid were "drying up or had dried up".  Can you explain what exactly would cause drying up of the cavities and what prognosis can we expect from this condition?
I am prepared to accept whatever response you offer so please be as direct as possible. Thank you so much. Michelle
