Vitamin B6 as add-on treatment in chronic schizophrenic and schizoaffective patients: a double-blind, placebo-controlled study.
BACKGROUND Vitamin B6 , or pyridoxine , plays an intrinsic role in the synthesis of certain neurotransmitters that take part in development of psychotic states . Several reports indicate that vitamin B6 may be a factor in a number of psychiatric disorders and related conditions , such as autism , Alzheimer 's disease , hyperactivity , learning disability , anxiety disorder , and depression . Moreover , there are anecdotal reports of a reduction in psychotic symptoms after vitamin B6 supplementation of psychopharmacologic treatment of patients suffering from schizophrenia or organic mental disorder . The aim of this study was to examine whether vitamin B6 therapy influences psychotic symptoms in patients suffering from schizophrenia and schizoaffective disorder . METHOD The effects of the supplementation of vitamin B6 to antipsychotic treatment on positive and negative symptoms in 15 schizophrenic and schizoaffective patients ( DSM-IV criteria ) were examined in a double-blind , placebo-controlled , crossover study spanning 9 weeks . All patients had stable psychopathology for at least 1 month before entry into the study and were maintained on treatment with their pre study  psychoactive and antiparkinsonian medications  throughout the study . All patients were assessed using the Positive and Negative Syndrome Scale ( PANSS ) for schizophrenia on a weekly basis . Patients r and omly received placebo or vitamin B6 , starting at 100 mg/day in the first week and increasing to 400 mg/day in the fourth week by 100-mg increments each week . RESULTS PANSS scores revealed no differences between vitamin B6- and placebo-treated patients in amelioration of their mental state . CONCLUSION Further studies with larger population s and shorter duration of illness are needed to clarify the question of the possible efficacy of vitamin B6 in treatment of psychotic symptoms in schizophrenia
