[edit] Diabetes Insipidus Reference

While psychogenic polydipsia is usually not seen outside the population of those with serious mental disorders, it may occasionally be found among others in the absence of psychosis, although there is no extant research to document this other than anecdotal observations. Such persons typically prefer to possess bottled water that is ice cold, consume water and other fluids at excessive levels, and may be falsely diagnosed as suffering from diabetes insipidus, since the chronic ingestion of excessive water can produce symptoms and diagnostic results that mimic mild diabetes insipidus.

Can the author provide a reference for this? It seems to me that diabetes insipidus is NOT something that can be misdiagnosed or is rarely FALSELY diagnosed.

Look at the following from the DI entry in wikipedia:

Habit drinking (in its severest form termed psychogenic polydipsia) is the most common imitator of diabetes insipidus at all ages. While many adult cases in the medical literature are associated with mental disorders, most patients with habit polydipsia have no other detectable disease. The distinction is made during the water deprivation test, as some degree of urinary concentration above isosmolar is usually obtained before the patient becomes dehydrated.

This seems to suggest that a water deprivation test is sufficient to quickly discover a case of psychogenic polydipsia.
