Tracking the chemical calling card of a killer stroke: New research hopes to decode molecular messages in brain
It?s been called a ?thunderclap? headache ? a sudden intense pain that?s the hallmark of a rare but usually deadly type of stroke called a subarachnoid hemorrhage (SAH). If the initial event doesn?t kill, as many as 30% of patients will suffer further strokes within two weeks from a blockage caused by blood vessels in spasm. Now, a neurosurgeon is hoping to someday prevent these secondary strokes by decoding ? and harnessing - the frenzied molecular messages produced by a stroke-choked brain.
