PTSD (Post Traumatic Stress Disorder) is a very complex diagnosis and often times those who have it may not be aware. If you have a child who has been witness to a traumatic event such as physical, verbal, sexual abuse, sudden loss of a loved one, or victim of a tragedy such as a car crash, etc, it is important to look out for certain indicators. These may include separation anxiety, avoidance of triggers reminding the child of the event, nightmares, repetitive play that reflects the traumatic event, frequent mood changes and irritability, etc.
Adults have similar yet variable symptoms which may include nightmares, avoidance of triggers reminding them of the event, anger, irritability, hostility, isolation, alcohol and drug use, a constant sense of fear, flashbacks or a sense of reliving the event, etc.
