Primary polydipsia or psychogenic polydipsia is a special form of polydipsia. It is usually associated with a patient's increasing fluid intake due to the sensation of having a dry mouth.
When the term "psychogenic polydipsia" is used, it implies that the condition is caused by mental disorders. However, the dry mouth is often due to phenothiazine medications used in some mental disorders, rather than the underlying condition.
Some forms of primary polydipsia are explicitly characterized as non-psychogenic.

Famous quotes containing the word primary:
“The primary function of myth is to validate an existing social order. Myth enshrines conservative social values, raising tradition on a pedestal. It expresses and confirms, rather than explains or questions, the sources of cultural attitudes and values.... Because myth anchors the present in the past it is a sociological charter for a future society which is an exact replica of the present one.”
—Ann Oakley (b. 1944)
