Post-traumatic stress disorder (PTSD) is a mental disorder that can develop following exposure to a traumatic event.
His diagnosis, recognized in the DSM 5 (Diagnostic and Statistical Manual of Mental Disorders and Psychiatric Disorders) and the ICD 11 (eleventh revision of the International Classification of Diseases), is defined by specific criteria evolving for more than a month after the event.
PTSD alters the social, family and professional functioning of the individuals it affects, plunging them, in many respects, into often disabling difficulties. Their quality of life, and that of those around them, is greatly diminished, with devastating consequences on an individual level: stress, falling self-esteem, development of a resignation mentality, etc.
