my neuroligist says I have too much spinal fluid on brain ventricle and without surgery I will have dementia at early age some symptoms now

You doctor is likely thinking of a shunt. This is generally successful, though all surgery has risks. I'd seek a second opinion just to feel more comfortable, but since your mother has dementia, this may be a clue. Still, a second opinion is often a good idea.

dln - Are you the one with too much spinal fluid? How would anyone know that? I have never heard of such a thing before, but then... But I agree, a second opinion is definitely in order.

I had neverheard of this either. My husband kept telling me something was wrong and then other people would make comments but I have been under a lot of stress lately. The neurologist did an MRI which showed the ventricles enlarged thus pressing against parts effecting memory coordination forgetfulness etc. I really got scared especially surgery on the brain. It is strange to wonder if you have done something and then forgot. I am now having headaches. Anybody else heard of this please let me know. Thanks for those who have already responded

I have this to and my eye doctor found it i went threw puberty and it went dorment 2 days before my surgery all i had before that was spinal taps and its coming back slowly but i get really bad headachs and i try and throw up my pupils are dilated and i sleep they put me on meds but they are killing my kidneys i wish they have a cure for thiss. p.s im only 13 i had it when i was 10-11
