Document Summary
Platelet aggregates (containing platelets and other blood cells) can form at and stick to the plaque surface: such an aggregate is known as a thrombus. Blood flowing past the plaque can break up the thrombus into smaller, free aggregates called emboli. For nat this meant for a time he couldn"t talk, as his speech centre was ischemic: the rest of his brain did receive a reasonable blood supply. This short period of ischemia with a specific loss of function is known as a tia: tias usually last less than 1 hour. Tias can result in temporary blindness (one or both sides), blurred vision, dizziness, blackouts, slurred speech (unintelligible), loss of sensation or movement on one side. So observe carefully your older relatives you could save their lives! After ct scan, knows that nat is not bleeding, no tumour, and no concussions. Nat is given aspirin and later has surgery to remove the plaque in his carotid artery.
