Posttraumatic Stress Disorder | Neuroprotective/Neurotrophic Effect of Lexapro® in Patients With Posttraumatic Stress Disorder

Posttraumatic Stress Disorder research study

What is the primary objective of this study?

The objectives of the current study are 1. to evaluate the efficacy of escitalopram in treatment for post-traumatic stress disorder, 2. to find the structural changes of brain using magnetic resonance imaging and its association with the symptoms reduction, and 3. to look at the differences of brain imaging findings and symptoms changes according to genetic differences of brain-derived neurotrophic factor (a biological molecule facilitating neuronal growth in human).
