Neurobehavioral investigation as a tool for revealing preclinical disorders

Abstract

This paper calls attention to the methodologies designed to investigate the higher cortical functions in order to elicit signis of encephalopathy in apparently normal conditions. This can be done by testing the blobal hemispheric funcionts or the interhemispheric functional balance. This shows up the clinical sequels that may precede or be the outcome both of transient pathological disorders, such as transient global anemia, migraine, TIAs and subarachnoid hemorrhage without apparent clinical consequences and of nontransient pathological conditions, such as epilepsy, occupational diseases, arterial hypertension and cerebral revascularization.
