WebOct 31, 2024 · A new study from Boston University is the first to illustrate that the brain’s cerebrospinal fluid pulses during sleep, and that these motions are closely tied with brain wave activity and blood flow. It may confirm the hypothesis that CSF flow and slow-wave activity both help flush toxic, memory-impairing proteins from the brain. WebThe calculated CSF stroke volume and the aqueductal CSF flow void score were compared with the surgical results. Results: All 12 patients with CSF stroke volumes greater than 42 microL responded favorably to CSF shunting. Of the six patients with stroke volumes of 42 microL or less, three improved with shunting while three did not.
