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.
Ischemic stroke occurs because of a loss of blood supply to part of the brain, initiating the ischemic cascade. Brain tissue ceases to function if deprived of oxygen for more than 60 to 90 seconds [citation needed], and after approximately three hours will suffer irreversible injury possibly leading to the death of the tissue, i.e., infarction.
