Gen Hosp Psychiatry. 2011 Jan-Feb;33(1):84.e9-10. doi: 10.1016/j.genhosppsych.2010.11.003. Epub 2010 Dec 13.


Polydipsia is a less examined but prevalent condition in patients with psychiatric disorders. It is usually described in schizophrenia but is rarely reported in bipolar affective disorder (BPAD). It is important to recognize and treat this entity as it can lead to serious complications. One needs to be cautious in choosing the mood stabilizer while treating this condition. We report the successful treatment of a patient with BPAD and polydipsia on a combination of valproate and risperidone.
