Abstract
The brain is particularly vulnerable to disturbances of body fluid osmolality. Studies in animals indicate that brain adaptation to osmotic stresses is a very complex process involving transient changes in water content and sustained changes in electrolyte and organic osmolyte contents. Appreciation of the nature of the adaptation process enables a better understanding of the marked variations in neurological sequelae that characterize hyper- and hypoosmolar states and provides a basis for more rational therapy.
