    Psychogenic water intoxication, often seen in psychiatric patients, causes convulsive coma due to severe hyponatremia. This condition involves excessive thirst and a unique hormonal imbalance, resolving spontaneously after a hypotonic polyuric phase.

    Area of Science:

    • Endocrinology
    • Nephrology
    • Psychiatry

    Background:

    • Water intoxication can lead to severe neurological symptoms like convulsive coma.
    • Psychiatric patients are disproportionately affected by water intoxication, sometimes without other predisposing conditions.

    Observation:

    • A stereotyped clinical picture of "psychogenic" water intoxication emerges, characterized by polydipsia (excessive thirst) and altered consciousness preceding seizures.
    • Patients exhibit severe hyponatremia (low blood sodium levels) during these episodes.

    Findings:

    • Free water clearance and dynamic antidiuretic hormone (ADH) suppression tests reveal hypovasopressinism (low ADH levels) that is resistant to inhibition.
    • This is associated with a "lower osmoreceptor reset," indicating a shift in the body's thirst and water balance regulation.

    Implications:

    • Understanding this "lower osmoreceptor reset" is crucial for managing psychogenic water intoxication.
    • The transient and sometimes relapsing nature of this condition highlights the need for ongoing monitoring in affected individuals, particularly in psychiatric populations.
