  • What causes PTSD in some people but not others?
    MedlinePlusMay 2026

    Researchers don't fully understand why some people develop PTSD after trauma while others don't, but genetics, brain chemistry, risk factors, and personal circumstances all play a role. It's not about being weak or strong—it's about how your brain and body respond to the traumatic event.

  • Why do I feel stressed long after my trauma is over?
    MedlinePlusMay 2026

    With PTSD, your brain and body stay in a stressed state even after the danger has passed, so you continue to feel frightened and on alert. Most people naturally recover from trauma over time, but people with PTSD don't feel better without help.

  • Is it normal to have flashbacks or nightmares about past events?
    MedlinePlusMay 2026

    Yes, flashbacks and nightmares are common PTSD symptoms where your mind replays the traumatic event as if it's happening again. These symptoms can feel very real and scary, but they're a sign that your brain is struggling to process what happened.
