Hypernatremia causes all EXCEPT?: (A) Seizure, (B) Pseudo- Paralysis, (C) Brain hemorrhage, (D) Cerebral edema
Answer is B. 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
