title: [Osmolality and ion concentration in the cerebrospinal fluid and blood serum in epilepsy and ischemic stroke].
abstract: A sharp (16.4%) increase of blood serum osmolality very close to the critical values was found in acute period of ischemic stroke, while sodiumemia exceeded the normal levels by 50 mmol/l and more. Meanwhile, the concentrations of Na ions in liquor of such patients was not significantly increased. The levels of Ca, K, Mg ions as well as the osmolality of blood serum and liquor were stable too. The alterations of these parameters were not significantly changed in epileptic patients out of fits. Both the analysis of the reasons of hyperosmia and hypersodiumemia development and the search for the methods of their prophylaxis and correction will be quite important in further investigations.
