Post-traumatic stress disorder (PTSD) is a type of anxiety perceived in people who have been victims or who have witnessed acts of extreme violence. These acts end up causing psychic, physical and emotional changes in people to the point that they are unable to live a normal life and need psychiatric monitoring.
In many situations, PTSD victims need to treat this disorder with the use of medications. However, the drugs used to treat PTSD provide minimal benefits for the treatment of PTSD. This is because people with this disorder are in a constant state of stress, feel that they are threatened at all times, making them always ready to fight or flee. Medicines suppress these sensations, causing mental wear and tear in individuals, which can make them apathetic, depressive.
