Q

Def: bleeding from a damaged blood vessel causes blood to accumulate at the surface of the brain. Blood fills a portion of the space between the brain & the skull & it mixes with the CSF. As blood flows into the CSF it increases pressure on the brain, which causes an immediate headache. Can lead to artery spasms which cause brain damage.
