Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate efficacy and safety of Polyunsaturated Fatty Acid for the prevention of Posttraumatic Stress Disorder (PTSD) in patients with accidental injuries.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Accidental injuries, mostly motor vehicle accident, in civilian population are frequent events.For instance, nearly one-third of injured patients appear to develop trauma-related psychiatric illness and the major diagnoses are post-traumatic stress disorder (PTSD) and depressive disorder.Omega-3 Polyunsaturated Fatty Acid (Omega-3 PUFA) has some evidence of efficacy of treatment in patients with anxiety and mood disorders, but no evidence of preventing anxiety and mood disorders that occur subsequent to accidental injuries.We evaluate efficacy and safety of Omega-3 PUFA for the secondary prevention of Posttraumatic Stress Disorder (PTSD) and related psychiatric illness in patients with accidental injury
