A. Kuruvilla et al., A STUDY ON SERUM PROLACTIN LEVELS IN SCHIZOPHRENIA - CORRELATION WITHPOSITIVE AND NEGATIVE SYMPTOMS, International clinical psychopharmacology, 8(3), 1993, pp. 177-179
Serum prolactin levels are determined in 116 schizophrenics and 120 co
ntrol subjects. Values of proclatin levels of the patients are compare
d with the values of controls of the same sex and age group. There is
no significant difference between prolactin levels of controls and tho
se with negative or positive symptoms of schizophrenia. Analysis, taki
ng age into account, also does not show any significant difference bet
ween patients with positive or negative symptoms and controls. The rel
ationship between nature of symptoms of schizophrenia and serum prolac
tin levels varies in different studies. The possible reasons for such
variations are discussed.
