1/3. Behavioral treatment of psychogenic polydipsia.This report describes the behavioral treatment of psychogenic polydipsia in an autistic, severely mentally retarded woman who had a history of self-induced water intoxication. Treatment emphasized the use of edibles and reductions in activity demands to reward water refusal. Employing this procedure, paraprofessional staff normalized the client's water consumption, and thereby prevented further episodes of potentially-fatal water intoxication.- - - - - - - - - - ranking = 1keywords = intoxication (Clic here for more details about this article) |
2/3. Fatal compulsive water drinking.In two cases of psychogenic polydipsia, water intoxication developed and contributed to the patient's death. The treatment of the patient with psychogenic polydipsia has been based on the presumed reversibility of the condition. Treatment of such patients must be reconsidered in light of these deaths.- - - - - - - - - - ranking = 0.5keywords = intoxication (Clic here for more details about this article) |
3/3. Fatal water intoxication in a case of psychogenic polydipsia.The term "water intoxication" is used to describe a condition of agitation, delirium, convulsion, and coma brought on by excessive intake of water, resulting in severe hyponatremia. Psychogenic polydipsia (compulsive water drinking) has until recently been considered a relatively benign process. Since 1974, however, three fatal cases of water intoxication, resulting from psychogenic polydipsia, have been reported. All three individuals died while hospitalized, thereby permitting performance of blood electrolyte determinations and documentation of the associated electrolyte imbalance. In the authors' case, there was a well-documented prior episode of water intoxication in which serum electrolytes showed a pattern typical of this entity. Death, however, occurred at home, thus preventing valid serum electrolyte determinations to be performed. Analysis of the vitreous humor revealed a severe hyponatremia, thus substantiating the diagnosis of fatal water intoxication. This case, once again, points out the usefulness of electrolyte analyses on the vitreous humor as an aid to establishing a cause of death.- - - - - - - - - - ranking = 4keywords = intoxication (Clic here for more details about this article) |
