What is the infarct? - correct answer ✔✔ region of cell death following energy failure resulting
in a reduction in blood flow
What is the pneumbra? - correct answer ✔✔ surrounding area of damaged tissue
, What are early warning signs of a stroke? - correct answer ✔✔ sudden weakness or numbness
of the face, arm, or leg

consequences? - correct answer ✔✔ University of Oxford ABCD scale
What pathogenesis occurs during acute infarct? - correct answer ✔✔ a portion of the affected
brain receives no blood, while a surrounding area receives sufficient blood from collateral
circulation to maintain viability but not to sustain function
The initial functional gains after the stroke are attributed to what? - correct answer ✔✔
reduction of cerebral edema, absorption of damaged tissue, and improved local vascular flow

obstruction within a blood vessel supplying blood to the brain

weakened vessel that ruptures and bleeds into the surrounding brain
How are stroke syndromes named? - correct answer ✔✔ according to the arteries that feed the
specific areas
