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.
This leads to the death of some brain cells. Many strokes are caused by blockages of the largest arteries in the brain. A lacunar stroke involves smaller arteries deep in the brain that branch off the large arteries. Because the arteries are smaller, the amount of brain tissue they feed is smaller than the amount fed by the large arteries. Still, lacunar strokes can cause significant disability.
