Hi, I have had one lumbar puncture subsequent to a brain MRI showing distended ventricals. After the lumbar puncture I was bed-ridden for a week and could hardly stand for more thana couple of minutes at a time and I experienced very bad headaches. I have had headaches of varying severity since then (beginning of June). I had another MRI last week to see if the CSF was blocking any of the ventricals and the report said the CSF flow is increased and the inflow stroke-volume is 55.6 microlitre, the outflow is 177.2 microlitre, conducive with NPH. However, as there is no obvious cause I'm reluctant to have a shunt installed - I've read that some people suffer very bad headaches after the VP Shunt has been installed which is not really the desired result.
Any ideas what could cause the headaches that should not be present in a normal NPH sufferer?
