Primary Outcome Measures:
  • Determine positive symptom treatment response in omega-3 fatty acid deficient first-episode schizophrenia patients augmented with omega-3 fatty acid supplementation vs. placebo. [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • Determine negative and cognitive symptom treatment response in omega-3 fatty acid deficient first-episode schizophrenia patients augmented with omega-3 supplementation vs. placebo. [ Time Frame: 12 months ]

Enrollment: 0
Study Start Date: January 2008
Study Completion Date: November 2009
Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Essential omega-3 fatty acid replacement Dietary Supplement: Omega-3 Fatty Acids

  • Docosahexaenoic acid fish oil concentrate at 1.6 grams
Other Names:
  • EPA
  • DHA
Dietary Supplement: EPA fish oil concentrate; DHA fish oil concentrate
3.2 grams for EPA 1.6 grams for DHA
Other Names:

Other Name: Olive oil

Detailed Description:
The two aims of the study test the hypotheses that correcting omega-3 fatty acid deficiency in the early stages of schizophrenia improves positive symptom treatment response, negative symptom treatment response, and cognition symptom response.
