简要总结
The purpose of this study is to determine if treatment with venlafaxine reduces symptoms of depression in persons with traumatic brain injury.
详细描述
The study evaluates the benefits of a promising antidepressant medication for the treatment of persons with traumatic brain injury (TBI) and major depressive disorder (MDD). The study is a randomized, double-blind, placebo-controlled trial of venlafaxine (a serotonin and norepinephrine reuptake inhibitor, also known as Effexor). Venlafaxine has been well established in the treatment of MDD in healthy individuals and is a recommended depression treatment agent for persons with TBI. By using a rigorous scientific methodology, this study will be an important first step in advancing the treatment of depression in this population beyond general impressions to proven treatments.
