Post-traumatic stress disorder (PTSD) is associated with war veterans who may suffer flashbacks, nightmares, and depression triggered by reminders of trauma. But research has shown that PTSD affects more than 7% of the U.S. population and some 8 million adults annually—and most are women. In fact, scientists say physical and sexual violence explains most PTSD cases in the U.S. Researchers have found women’s trauma symptoms often are precipitated by rape and abuse… but shame and social stigma may keep them from seeking help, like counseling. Both men and women with PTSD may become emotionally numb, easily frightened, and lose interest in the things they once enjoyed. Harvard Chan School researchers have conducted studies linking trauma to a wide range of conditions, including type 2 diabetes, heart disease, and obesity. They are studying how the prolonged effects of PTSD and trauma may be passed down genetically or by other means through generations. By understanding the roots of PTSD and helping to erase the stigma often associated with it, researchers hope to help victims find relief and live life to the fullest.
