Utility of Cognitive Function Assessment in Patients Undergoing Surgery on a Third Level Hospital in Mexico City

Abstract

The brain is the main site of action of anesthetic drugs. For many years, it was assumed that their effects did not go beyond their pharmacological action and that the brain was restored to its previous state once the agent was removed. However, there is increasing evidence that supports other notion. There may be long-term and even permanent anatomical and functional changes after the administration of anesthetic drugs.The brain may be more vulnerable at the first and final stages of life.
