Babies born at less than 37 weeks gestation (premature) have different nutritional needs than babies born at full term (after 38 weeks). Premature babies will often stay in the neonatal intensive care unit. There they are watched closely to make sure they are getting the right balance of fluids and nutrition.
Watershed Stroke. Watershed strokes. are usually the result of poor blood flow to the brain from occlusion of the arteries in the neck (from atherosclerosis) or periods of poor cardiac function, such as during a heart attack.
Causes. A stroke occurs when the blood supply to your brain is interrupted or reduced. This deprives your brain of oxygen and nutrients, which can cause your brain cells to die. A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke). Thrombotic stroke. 2  A thrombotic stroke occurs when a blood clot (thrombus) forms in one of the arteries that supply blood to your brain. 3  A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions. 4  Embolic stroke.
