Post-Traumatic Stress Disorder

Posttraumatic stress disorder (PTSD, also rendered with a hyphen as post-traumatic stress disorder) is a severe anxiety disorder that can develop after exposure to any event which results in psychological trauma. This event may involve the threat of death to oneself or to someone else, or to one’s own or someone else’s physical, sexual, or psychological integrity, overwhelming the individual’s ability to cope. As an effect of psychological trauma, PTSD is less frequent and more enduring than the more commonly seen acute stress response.

Bulimia nervosa

Bulimia nervosa is an eating disorder characterized by recurrent binge eating, followed by compensatory behaviors. The most common form is defensive vomiting, sometimes called purging; fasting, the use of laxatives, enemas, diuretics, and over exercising are also common. The word bulimia derives from the Latin (būlīmia), which originally comes from the Greek βουλιμία (boulīmia; ravenous hunger), a compound of βους (bous), ox + λιμός (līmos), hunger.
