What are stress and post-traumatic stress disorder ( PTSD ) ?

Stress is a state of physiological or psychological strain caused by adverse stimuli, physical, mental, or emotional, internal or external, that tend to disturb the functioning of an organism and which the organism naturally desires to avoid. Post traumatic stress disorder ( PTSD ) is an emotional illness that develops as a result of a terribly frightening, life-thretening, or otherwise highly unsafe experience.
