Document Summary
Suffered a stroke that led to changes in behavior and personality. Right frontal cortex - precentral gyrus (primary motor cortex - m1) Interruption of blood flow to the brain that kills brain cells and causes sudden appearance of neurological symptoms (death of neurons) Ischemia - deficiency of blood flow to the brain due to functional constriction of to the actual obstruction of a blood vessel (causes about 80% of strokes) If arteries in brain had blood clot and blood could no longer reach brain areas. Can be treated with tissue plasminogen activator (t-pa) Allows return of normal blood flow to affected region. Needs to be given within three hours of stroke. Anticlotting drug decreases tissue death in ischemic stroke but aggravates cell deat in hemorrphagic stroke. Hemorrhagic stroke - burst of a blood vessel bleeding into brain (causes about 20% of strokes) If you sustained an injury and your blood vessels burst.
