The Influence of Vitamin D Supplementation on Serum Brain Derived Neurotrophic Factor Level and Cognitive Function in Schizophrenia Treated With Atypical Antipsychotic

The objective of the study is to evaluate the influence of vitamin D supplementation on Serum Brain Derived Neurotrophic Factor level and cognitive function in schizophrenia treated with atypical antipsychotic. Methods: The investigator will use randomized controlled trial design. 40 chronic schizophrenia patients with vitamin D insufficiency or deficiency treated with atypical antipsychotic, will be randomly assign (1:1 ratio) to receive either daily oral cholecalciferol 2000 IU or placebo for 8 weeks. Assessment of BDNF serum and cognitive function will be performed at baseline and after 8 weeks period.
