Post-traumatic stress disorder (PTSD) symptoms can significantly impact daily life. Learn about symptoms of PTSD, post-traumatic stress disorder diagnosis.Post-traumatic stress disorder (PTSD) signs and symptoms can severely impact day-to-day life and that's why it's important to get PTSD help as soon as possible. Post-traumatic stress disorder is a mental illness that develops after experiencing, or being exposed to, an event that physically harms or threatens to physically harm someone. This harm, or threat of harm, may be directed towards the sufferer or another individual.

Post-traumatic stress disorder (PTSD) symptoms include the persistent reliving of the trauma, avoidance of any place that is a trauma-reminder, trouble sleeping and many others. PTSD symptoms can be terrifying and life-altering, as the person tries to avoid any situation that may bring about severe anxiety. This avoidance can make a person's world much smaller and allow them to do fewer and fewer things as they fear the re-emergence of their post-traumatic stress disorder symptoms. They may even turn to drugs to numb the psychological pain caused by their symptoms.

Prior to 1980, symptoms of PTSD were seen as a personal weakness or character flaw and not as an illness. It is now known, however, that post-traumatic stress disorder symptoms are caused by physical changes in the brain and not due to a person's character.
