Post-traumatic stress disorder (PTSD) is a mental health condition that can affect kids who have experienced something very upsetting. They have extreme anxiety that causes issues like trouble sleeping, being easily annoyed, or feeling detached from others.  Experiences that might be traumatic include violence, abuse, natural disasters, or bad accidents. Kids with PTSD might have experienced the upsetting event themselves. PTSD can also happen if the child sees it happen to someone else or hears about it happening to someone they’re close to. It’s normal for kids to be upset when something traumatic happens. The difference is that kids with PTSD are still very anxious months later.  PTSD isn’t common in young people, but both children and teenagers can experience it. Getting a lot of support right after the upsetting event can help them avoid developing PTSD.
