Alzheimer's Disease

Fluid on the Brain from Dementia



My mother had a CT for dementia or alzheimer disease. The doctor said there is fluid on her brain. Is it dangerous or is the brain shrinking?


Unfortunately, it would be impossible to make any comment on a scan that I have not seen. If there is shrinkage of the brain tissue than fluid would build up in its place naturally and the excess fluid would not have any inherent danger. If the fluid is trapped and is blocked from circulating, than there may be danger from this. I would call to ask your mother's doctor.
