All water: a case of acute hyponatraemia

MUDr. Jakub Pecl
Dětské oddělení, Orlickoústecká nemocnice

The case report presents a boy who was treated with desmopressin for polyuria and polydipsia, and was suspected to have central

diabetes insipidus. During the treatment, he developed generalized tonic-clonic seizures and disturbance of consciousness

due to acute hyponatraemia with water intoxication, a condition referred to as hyponatraemic encephalopathy. Following the

revision of diagnosis, a definitive diagnosis was made of psychogenic polydipsia with an underlying ADHD. The case report aims

to highlight the need to perform a complete examination algorithm in the differential diagnosis of polydipsia and polyuria, even

prior to commencing pharmacological treatment.

Keywords: psychogenic polydipsia, water intoxication, acute hyponatraemia, hyponatraemic encephalopathy
