  • Title: [Psychogenic water intoxication].
    Author: Gebel F, Meng H, Michot F, Truniger B.
    Journal: Schweiz Med Wochenschr; 1989 Feb 11; 119(6):169-77. PubMed ID: 2648558.
    Abstract:
    Six new cases of psychogenic water intoxication are discussed in the light of 150 observations published in the literature since 1935. 87% of all patients were schizophrenic, and 13% had other psychoses and a variety of functional and organic psychopathies. Psychogenic polydipsia is a prerequisite of psychogenic water intoxication. Water intake either overrides an intact osmoregulation (46% of all cases) or, allied to an inadequate urinary dilutional capacity (54%), leads to a transitory, sometimes repeated, and (in 8% of all cases) lethal water intoxication and hypoosmolality. - The consequence of hypoosmolality is metabolic encephalopathy, with agitation, convulsions and coma as its most common symptoms. Profuse diuresis, enuresis and urinary retention, gastric dilatation, watery vomiting and watery diarrhea are diagnostically helpful symptoms of polydipsia typically denied by the patients. Hypoosmolality/hyponatremia are the hallmarks of water intoxication. However, fewer than 50% of all patients present with the expected maximal urinary dilution. Inadequate ADH activity and increased sensitivity of the renal tubule to antidiuretic hormone are the pathogenetic factors in this inappropriate urinary dilution, while psychosis, psychotropic drugs, diuretics, nicotine and alcohol withdrawal are possible causes and cofactors of polydipsia and inadequate urinary dilution. New aspects of treatment are discussed.
