1. A method, comprising:
- implanting a first electrode within a subarachnoid cavity of a brain of a subject who is asymptomatic of Alzheimer'"'"'s disease, and a second electrode outside of the subarachnoid cavity of the brain of the subject who is asymptomatic of Alzheimer'"'"'s disease; and
electroosmotically driving fluid between a site within the subarachnoid cavity of the brain of the subject and a site outside of the subarachnoid cavity of the brain of the subject who is asymptomatic of Alzheimer'"'"'s disease, by applying a treatment voltage between the first and the second electrodes in order to reduce risk for developing Alzheimer'"'"'s disease.

Abstract
Apparatus for driving fluid between first and second anatomical sites of a subject is provided, comprising (1) a first electrode, configured to be coupled to the first anatomical site of the subject; (2) a second electrode, configured to be coupled to the second anatomical site of the subject; and (3) a control unit, configured to (i) detect a pressure difference between the first and second anatomical sites, and (ii) in response to the detected pressure difference, drive fluid between the first and second anatomical sites by applying a treatment voltage between the first and second electrodes. Other embodiments are also described.

7. A method, comprising:
-
implanting a first electrode within a subarachnoid cavity of a brain of a subject, and a second electrode outside of the subarachnoid cavity of the brain of the subject; electroosmotically driving fluid between a site within the subarachnoid cavity of the brain of the subject and a site outside of the subarachnoid cavity of the brain of the subject, by applying a treatment voltage between the first and the second electrodes; and detecting a pressure difference between the site within the subarachnoid cavity of the brain of the subject and the site outside of the subarachnoid cavity of the brain of the subject, wherein applying the treatment voltage comprises applying the treatment voltage in response to the detected pressure difference, wherein detecting the pressure difference comprises detecting a voltage between the site within the subarachnoid cavity of the brain of the subject and the site outside of the subarachnoid cavity of the brain of the subject, and wherein applying the treatment voltage comprises applying the treatment voltage in response to the detected voltage. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
