PTSD

PTSD is a common and treatable mental health condition that can develop after experiencing or witnessing trauma. Learn about symptoms, causes, diagnosis and available treatments.

Posttraumatic stress disorder, or PTSD, is a mental health condition that can develop after a person experiences or witnesses a traumatic event, such as combat, sexual or physical assault, serious accidents, natural disasters or other situations that threaten life or safety. PTSD is not a sign of weakness. It is a common, treatable response to extreme stress.

Common Symptoms of PTSD

  • Intrusive memories: Distressing thoughts, flashbacks or upsetting dreams related to the event.
  • Avoidance: Efforts to avoid thoughts, places, people or activities that remind you of the trauma.
  • Negative changes in thoughts and mood: Ongoing negative beliefs, difficulty feeling positive emotions, feeling detached from others or memory problems related to the trauma.
  • Changes in arousal and reactivity: Being easily startled, feeling tense or on guard, irritability or anger, trouble concentrating or difficulty sleeping.

When Symptoms Start and How PTSD Progresses
Symptoms often begin within weeks of a traumatic event, but they may appear months or even longer afterward. For a PTSD diagnosis, symptoms typically last more than one month and cause significant distress or problems in daily life. When similar symptoms last less than one month, they may be referred to as acute stress disorder.

Causes and Risk Factors
PTSD develops after direct or indirect exposure to trauma. Factors that increase risk include:

  • Severe or prolonged traumatic experiences
  • A history of anxiety or depression
  • Limited social support
  • Ongoing life stressors
  • Certain genetic or biological factors
    Women are statistically more likely to develop PTSD, but anyone can be affected.

Diagnosis and Assessment
PTSD is diagnosed by a qualified clinician through a clinical interview and established diagnostic criteria. Evaluation may include:

  • Clinical interviews focused on symptoms and history
  • Screening tools such as the PTSD Checklist (PCL-5)
  • Structured interviews like the Clinician-Administered PTSD Scale (CAPS-5)
    Assessment also looks for related conditions, such as depression, substance use or traumatic brain injury, which can affect diagnosis and treatment planning.

If you or someone you care about continues to struggle after a traumatic event, speaking with a trained clinician can help clarify what is happening and connect you with effective care. If there is concern about immediate harm to yourself or others, seek urgent help.

What is PTSD?
PTSD is a mental health condition that can develop after experiencing or witnessing trauma. It involves intrusive memories, avoidance behaviors, negative changes in mood and thinking and heightened arousal or reactivity.

Who can get PTSD?
Anyone can develop PTSD, including adults, adolescents and children. Risk varies based on the type of trauma, personal history, social support and biological factors.

How soon after a trauma do symptoms appear?
Symptoms may begin within days or weeks, or they may be delayed for months or longer. Symptoms lasting more than one month and affecting daily life may indicate PTSD.

How is PTSD diagnosed?
A trained clinician uses clinical interviews and standardized criteria to diagnose PTSD. Screening tools and structured interviews help assess symptom severity and rule out other conditions.

Is PTSD a sign of personal weakness?
No. PTSD is a medical condition related to how the brain and body respond to trauma, not a personal failing.

Is PTSD treatable?
Yes. Effective treatments include trauma-focused therapies such as cognitive behavioral therapy, prolonged exposure, cognitive processing therapy and certain forms of EMDR. Medication may also help reduce symptoms for some people.

What should I do if I think I have PTSD?
Reach out to a primary care practitioner or a mental health professional for an evaluation. If you are in immediate danger or thinking about harming yourself, seek emergency care or contact a crisis line right away.

Can children have PTSD, and how is it different?
Yes. Children can develop PTSD, and symptoms may look different, such as reenacting trauma during play, regression, bedwetting or increased clinginess. Care should be age-appropriate and involve caregivers when possible.

What helps day to day while getting treatment?

  • Building predictable routines
  • Staying connected with supportive people
  • Practicing healthy sleep habits
  • Limiting alcohol and substance use
  • Using grounding techniques for distressing memories
  • Following a coping plan developed with a clinician
    Support from family, friends or support groups can also be helpful. If you have questions or concerns, a confidential conversation with a healthcare professional can provide guidance tailored to you.
