An estimated 8 percent of Americans are thought to be suffering from Post-Traumatic Stress Disorder at any given time. Many are victims of or witnesses to violence. Others have been neglected or abused. Some have experienced a traumatic accident or natural disaster. Still others have experienced the sudden and perhaps violent death of someone they love. No matter the cause, PTSD results in symptoms of acute stress, including anxiety, persistent thoughts or flashbacks, and a host of other physical, emotional, cognitive, social, and spiritual challenges.
