Overview

  • PTSD is a psychiatric disorder that may occur in people who have experienced or witnessed a traumatic event. Children, teens, and adults can all develop PTSD. Anyone, at any age, can be affected — not only veterans, though those who experience deliberate harm or repeated trauma are at greater risk.
  • According to NAMI, PTSD affects 3.6% of U.S. adults (~9 million people). Women are significantly more likely to experience PTSD than men. About 37% of those diagnosed are classified as having serious symptoms.
  • PTSD differs from a normal trauma response in that symptoms persist beyond one month and significantly impair functioning. Symptoms can appear within a month of the event or not until years later.
  • PTSD symptoms fall into four categories: intrusion (flashbacks, nightmares), avoidance, arousal and reactivity, and changes in cognition and mood. It frequently co-occurs with depression, anxiety, and substance use disorders.
  • Causes include experiencing or witnessing trauma. Not everyone who experiences trauma develops PTSD — risk factors include prior mental health history, lack of support, and genetics.
  • PTSD is treatable. Therapy (especially CPT, prolonged exposure, and CBT) and medication (SSRIs, SNRIs) are most effective. Take our PTSD assessment as a first step.

Symptoms of Post Traumatic Stress Disorder

PTSD is distinguished from a normal stress response when symptoms persist beyond one month and impair functioning. PTSD often co-occurs with substance use disorders, depression, and anxiety. 

  • Intrusion: Flashbacks, nightmares, vivid unpleasant memories, and intense mental or physical distress when reminded of the trauma.
  • Avoidance: Avoiding people, places, or situations that trigger memories; avoiding related thoughts or feelings; emotional numbing or detachment from daily life.
  • Arousal and reactivity: Feeling on edge, easily startled, irritability, angry outbursts, reckless or self-destructive behavior.
  • Cognition and mood: Negative thoughts about oneself or the world; distorted guilt or blame; loss of interest in previously enjoyed activities; difficulty remembering the traumatic event; increasing detachment from others and emotions.

Causes of PTSD

PTSD can develop after experiencing or witnessing a traumatic event or prolonged traumatic exposure. Per the DSM-5, exposure to “actual or threatened death, serious injury, or sexual violence” is required for a PTSD diagnosis. Not everyone who experiences trauma develops PTSD. 

  • Pre-existing depression or anxiety
  • Lack of support from family or friends
  • History of repeated or childhood trauma
  • Genetic factors: a large genetic study found genetics accounts for 5–20% of variability in PTSD risk following a traumatic event.

Types of PTSD

  • Complex PTSD (C-PTSD): Results from multiple traumas (ongoing abuse, domestic violence, repeated war exposure). Often co-diagnosed with borderline or antisocial personality disorder or dissociative disorders. Treatment takes much longer. See: What Is C-PTSD?, C-PTSD vs. PTSD.
  • Dissociative PTSD: Characterized by dissociative episodes (depersonalization, derealization) rather than reactive episodes. Associated with high PTSD severity, significant early life trauma, and higher rates of co-existing psychiatric disorders.
  • Comorbid PTSD: PTSD alongside one or more additional mental health conditions and/or a substance use disorder. Extremely common. Both conditions should be treated simultaneously.

Treatment

PTSD symptoms can be treated. You may need to try different approaches to find what works best. Always seek treatment from a professional experienced with PTSD. 

1. Therapy

Talk therapy helps people learn new ways to react to triggers, manage anxiety and anger, and process shame or guilt from trauma. 

  • CPT (Cognitive Processing Therapy): CPT focuses on how the traumatic event is perceived and processed. Involves discussing the trauma and writing about it in detail, then examining and reframing thoughts about the experience.
  • Prolonged Exposure (PE): Gradually approaches trauma-related memories, situations, and emotions. The goal of exposure therapy for PTSD is to reduce avoidance of trauma reminders.
  • CBT: Trauma-focused CBT identifies, understands, and modifies thought patterns and behaviors related to the trauma.
  • Stress Inoculation Training (SIT): Teaches breathing techniques and methods to stop negative thoughts; builds coping skills for PTSD-accompanying stress.
  • EMDR: Patients focus on a sound or back-and-forth movement while thinking about the trauma memory.
  • Present Centered Therapy (PCT): Non-trauma-focused; addresses current stressors related to PTSD rather than processing the trauma directly.

2. Medication

  • SSRIs: Most commonly prescribed for PTSD. Examples include Zoloft, Paxil, and Prozac.
  • SNRIs: Less common but can be effective. Your provider can help determine the best fit.

3. Natural Remedies & Coping Strategies

Journaling, meditation, and exercise can all support recovery. Avoid alcohol and drugs — they can worsen outcomes over time.

Types of PTSD

Research has shown that there are what can be considered several different types of PTSD, depending on how symptoms present and trauma circumstances. Researchers continue to explore PTSD symptoms that can require different treatment methods.

Complex PTSD is also known as complicated PTSD and is the result of multiple traumas. This type of PTSD is common in situations involving abuse or domestic violence or repeated exposure to war. Individuals who experience this type of PTSD are often diagnosed with borderline or antisocial personality disorder or dissociative disorders, too. As a result, treatment for this type of PTSD can take much longer.

What are the common signs of PTSD?

The most recognizable signs are persistent symptoms following a traumatic event that last beyond one month and impair daily functioning. These fall into four categories: intrusion (flashbacks, nightmares, vivid memories), avoidance (avoiding triggers, emotional numbness), arousal and reactivity (hypervigilance, angry outbursts, recklessness), and changes in cognition and mood (negative self-view, guilt, loss of interest, detachment). PTSD often co-occurs with depression, anxiety, and substance use disorders. Take our PTSD assessment as a first step.

How do you get diagnosed with PTSD?

Diagnosis is made by a licensed mental health care provider. While it is natural to have some PTSD-like symptoms for a few weeks after a traumatic event, a clinical diagnosis applies when symptoms persist longer and significantly impair functioning. Per the DSM-5, the person must have been exposed to actual or threatened death, serious injury, or sexual violence. The clinician will assess which of the four symptom clusters are present, duration, and functional impairment. Take our PTSD assessment before your first appointment.

Who can diagnose PTSD?

Psychiatrists, psychologists, and licensed clinical therapists are qualified to diagnose PTSD. A primary care physician can conduct initial screening and refer to a mental health specialist. Because PTSD frequently co-occurs with depression, anxiety, and substance use disorders, an experienced clinician familiar with trauma-related conditions is important for an accurate diagnosis and effective treatment plan.

Can an online therapist diagnose PTSD?

Yes. Licensed therapists and psychiatrists practicing via telehealth can evaluate and diagnose PTSD. Online therapy is also an effective treatment option — CBT, CPT, and prolonged exposure therapy, the most evidence-based approaches for PTSD, are all available in online formats. An online psychiatrist can also support medication management.

What type of therapy is best for PTSD?

CPT (Cognitive Processing Therapy), Prolonged Exposure (PE), and trauma-focused CBT are the most evidence-based therapies for PTSD. CPT focuses on how the trauma is perceived and reframed; PE gradually reduces avoidance of trauma reminders; CBT directly targets the thought patterns and behaviors sustaining PTSD. EMDR, SIT, and PCT are also used depending on individual circumstances. In most cases, therapy is most effective when combined with medication.

When should you seek professional help for PTSD?

Seek professional help if symptoms related to a traumatic event have persisted for more than one month and are meaningfully disrupting your ability to work, maintain relationships, or function in daily life. Do not wait until symptoms become severe. Many people experience PTSD for years before seeking help; early treatment leads to significantly better outcomes. If you are experiencing thoughts of self-harm, seek help immediately.

Can PTSD be treated?

Yes. PTSD symptoms can be treated. A combination of therapy and medication is the most effective approach for most people. Therapy — especially CPT, prolonged exposure, and CBT — helps process trauma and change how you respond to triggers. SSRIs and SNRIs can help manage symptoms. Natural strategies like journaling, meditation, and exercise also support recovery. You may need to try different treatments to find what works best.

What are the different ways to treat PTSD?

Your mental health care provider may use any of the following, or a combination, based on your symptoms and experiences.

Each person’s PTSD recovery journey is different. Past trauma (including childhood trauma) can impact life years later. A combination of talk therapy and medication is most common, but the right approach is individualized.

  • CPT: Examines and reframes how you perceive and process the traumatic event.
  • Prolonged Exposure (PE): Gradually approaches trauma-related memories and situations to reduce avoidance.
  • CBT: Identifies and modifies thought patterns and behaviors related to the trauma.
  • SIT: Teaches stress and anxiety management techniques; builds coping skills.
  • EMDR: Focuses attention on a sound or movement while thinking about the trauma memory.
  • PCT: Non-trauma-focused; addresses current stressors related to PTSD symptoms.
  • SSRIs: Zoloft, Paxil, Prozac. See: Medications to Treat PTSD.
  • SNRIs: Less common but effective for some. Your provider can determine the best fit.

How prevalent is PTSD?

According to NAMI, PTSD affects 3.6% of the U.S. adult population — approximately 9 million individuals. About 37% of those diagnosed are classified as having serious symptoms. Women are significantly more likely to experience PTSD than men.
