We have considered two approaches, the classical view focused on hormonal influences in the regulation of aggression and the most recent view which accounts for the influences of aggressive behavior and social status on hormonal secretion. In this review we differentiate the organizational from the activational effects. The main conclusions are referred to the gonadal steroids effects both organization and activation of the neural subtract of aggression. Among them it seems that aromatizable androgens have the most important effects. On the other hand, the testosterone would be predictive for dominant social status, the corticosterone would be for submission and finally, the ACTH would be predictive for the aggressive behavior but not for submission. In addition to that the literature point that the defeat experience is the main factor in submission. Referred to the effects of behavior on hormonal secretions, all the studies point out that social interaction elicits sympathetic-medullar and gonadal activation in the dominant animals and cortico-adrenal activation in the submissive ones.</p>","PeriodicalId":8654,"journal":{"name":"Archivos de neurobiologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12502478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pathogenesis is largely disputed. An NMS case is presented which was triggered by flupentixol and was associated with severe hyponatremia (116 mmol/l upon admission). Both clinically and analytically, the hyponatraemia fulfills criteria to be considered secondary to an inappropriate secretion of antidiuretic hormone (SIADH). Other possible causes of hyponatraemia were ruled out. After early treatment with dopaminergic agonists and water restriction, both conditions improved in parallel. The different pathogenetic possibilities which may explain the temporal coexistence of both syndromes in the same patient are discussed.
