Risk Factors, Clinical Presentations and Predictors of Stroke Form

Instructions and help about Risk Factors, Clinical Presentations And Predictors Of Stroke

There are two main types of stroke: an ischemic stroke which is when there’s a blocked artery that reduces blood flow to the brain and a hemorrhagic stroke which is when an artery in the brain breaks, creating a pool of blood that damages the brain. Of the two, ischemic strokes are much more common, and the amount of damage they cause is related to the parts of the brain that are affected and how long the brain suffers from reduced blood flow. Now if symptoms self-resolve within 24 hours, it’s called a transient ischemic attack and there are usually minimal long-term problems. OK - let’s start with some basic brain anatomy. The brain has a few regions - the most obvious is the cerebrum, which is divided into two cerebral hemispheres, each of which has a cortex - an outer region - divided into four lobes including the frontal lobe, parietal lobe, temporal lobe, and the occipital lobe. There are also a number of additional structures - including the cerebellum, which is down below,
