<prompt> Hypernatremia causes all EXCEPT?SeizurePseudo- ParalysisBrain hemorrhageCerebral edema  <response>: Sudden shrinkage of brain cells in acute hypernatremia may lead to parenchymal or subarachnoid hemorrhages Brain cells accommodate to a chronic in ECF osmolality 48h by activating membrane transpoers- influx and intracellular accumulation of organic osmolytes- increase in ICF water and normalization of brain parenchymal volume. Cellular response to chronic hypernatremia predisposes these patients to the development of cerebral edema and seizures during overly rapid hydration
