Primary hypoparathyroidism: psychosis in postpartum period.

We report a 30-yr-old lady who was being treated as postpartum psychosis. Patient had generalized tonic clonic convulsions and was found to have bilateral cataract. Her serum calcium, serum magnesium and serum parathyroid were low. On correction of serum magnesium her PTH did not increase. She was hence diagnosed as primary hypoparathyroidism. On correction of her serum calcium her psychosis improved.
