PTSD (Post-Traumatic Stress Disorder)
A reaction to trauma that can be treated
Quick Facts
- Type: Trauma-related mental health condition
- Trigger: Experiencing or witnessing trauma
- Key symptoms: Flashbacks, nightmares, avoidance, hypervigilance
- Treatments: Trauma-focused therapy, medication
Overview
Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after a person experiences, witnesses, or learns about a frightening or life-threatening event. Examples include serious accidents, physical or sexual assault, combat, natural disasters, and abuse.
Most people who go through trauma have distressing reactions that ease over time. In PTSD, these reactions persist for more than a month and interfere with daily life. The condition involves reliving the trauma, avoiding reminders of it, feeling constantly on guard, and changes in mood and thinking. PTSD is not a sign of weakness, and it can affect anyone. It is treatable, and trauma-focused therapies and medication help many people recover or manage symptoms well.
Symptoms
PTSD symptoms usually fall into four groups and last longer than a month.
- Re-experiencing: Intrusive memories, flashbacks where the event feels like it is happening again, nightmares, and intense distress at reminders.
- Avoidance: Staying away from people, places, activities, or thoughts that recall the trauma.
- Negative changes in mood and thinking: Persistent fear, guilt, or shame, feeling detached or numb, loss of interest, and difficulty remembering parts of the event.
- Increased arousal: Being easily startled, feeling on edge, irritability or angry outbursts, trouble sleeping, and difficulty concentrating.
Symptoms may begin soon after the trauma or appear months later, and they can come and go. Children may show symptoms differently, such as reenacting the event in play.
Causes
PTSD is triggered by exposure to a traumatic event, but not everyone who experiences trauma develops it. Several factors influence the risk.
- The trauma itself: More severe, prolonged, or repeated trauma, and trauma involving personal harm, increase risk.
- Biological factors: Differences in how the brain and stress-response systems handle fear and memory, and inherited tendencies.
- Previous experiences: Earlier trauma, including in childhood, and prior mental health problems.
- Lack of support: Limited support after the event, or additional stress afterward.
Risk Factors
- Experiencing intense, prolonged, or repeated trauma
- Previous traumatic experiences, especially in childhood
- A personal or family history of anxiety, depression, or other mental illness
- Jobs with high trauma exposure, such as military, emergency, or healthcare work
- Lack of social or family support after the event
- Additional life stress, or problem alcohol or drug use
Diagnosis
PTSD is diagnosed by a mental health professional through a clinical assessment.
- Clinical interview: Discussing the traumatic event and the pattern, duration, and impact of symptoms.
- Diagnostic criteria: Symptoms from the re-experiencing, avoidance, mood, and arousal groups lasting more than a month and causing significant distress or impairment.
- Screening tools: Questionnaires that help identify and measure symptoms.
- Medical review: To check for coexisting conditions such as depression, anxiety, or substance use.
Treatment
PTSD is treatable, and trauma-focused psychological therapies are the cornerstone of care.
- Trauma-focused psychotherapy: Approaches such as trauma-focused cognitive behavioral therapy, prolonged exposure, cognitive processing therapy, and eye movement desensitization and reprocessing (EMDR) help people process the trauma.
- Medication: Certain antidepressants (SSRIs and SNRIs) can reduce symptoms and are often used alongside therapy.
- Skills and support: Learning grounding and relaxation techniques, improving sleep, and building support networks.
- Treating related problems: Addressing depression, anxiety, and alcohol or drug use that often accompany PTSD.
Self-Care and Coping
- Seek support from trusted people and consider professional help early
- Learn grounding and relaxation techniques to manage distress
- Keep to a routine, with regular sleep, meals, and activity
- Stay physically active, which can ease stress and improve sleep
- Avoid using alcohol or drugs to cope, as they tend to worsen symptoms
- Be patient with yourself; recovery takes time and is possible
When to See a Doctor
See a doctor or mental health professional if distressing reactions to a traumatic event last more than a month, get worse, or interfere with your daily life, work, or relationships. Effective treatments are available, and getting help does not mean you are weak. Seek emergency help immediately, or contact emergency services or a suicide and crisis helpline, if you have thoughts of harming yourself or others, or feel unable to keep yourself safe. Support is available, and these feelings can improve with treatment.
Frequently Asked Questions
What is PTSD?
Post-traumatic stress disorder is a mental health condition that can develop after experiencing or witnessing a traumatic event. It involves reliving the trauma through flashbacks and nightmares, avoiding reminders, feeling on edge, and changes in mood and thinking that last more than a month.
Does everyone who experiences trauma get PTSD?
No. Most people have distressing reactions after trauma that ease over time. PTSD develops in some people when these reactions persist beyond a month and interfere with daily life, and certain factors such as the severity of the trauma and lack of support raise the risk.

Can PTSD develop long after the event?
Yes. While symptoms often begin within a few months of the trauma, they can sometimes appear or worsen months or even years later, particularly when triggered by reminders or new stress. It is still treatable whenever it emerges.
