Ischemia
The word "ischemia" () is from Greek ἴσχαιμος "iskhaimos", "staunching blood" from ἴσχω "iskhο", "keep back, restrain" and αἷμα "haima", "blood".
Hypothermia cap
The use of hypothermia caps has also shown promise in inhibiting stroke paralysis. Studies are underway testing a combination treatment consisting of four drugs plus a hypothermia cap to try to slow the cell death that is triggered by an ischemic stroke. Ischemic strokes are caused when a clot blocks blood flow to the brain, and comprise roughly 80% of all strokes. The slowing of cell death is theorized to give the brain time to find an alternate blood supply through unblocked arteries, meaning patients may potentially avoid physical and speech impairments caused by ischemic strokes.
