For many years, it was assumed that post-traumatic stress disorder (PTSD) only affected people who had been in active combat in the military. Today, however, it’s understood that PTSD can also affect those who have experienced a variety of different dangerous situations or other traumas in their lives. It’s estimated that around 6% of the US population will experience PTSD at some point in their lives. 

When it comes to making an official diagnosis, mental health professionals typically compare the symptoms an individual is experiencing against the guidelines set out in the Diagnostic and Statistical Manual of Mental Disorders (DSM). We’ll explore these guidelines below. Remember that an official, clinical diagnosis of any mental health disorder can only come from a licensed, qualified healthcare professional.

Are you experiencing symptoms of PTSD?

Criterion A

First, the individual must have experienced a traumatic incident in order for a PTSD diagnosis to be possible. The event must have involved them experiencing, witnessing, or learning that a loved one experienced actual or threatened death, serious injury, or sexual violence.

Criterion B

Next, the individual must persistently relive or re-experience the event in at least one of the following ways: 

  • Unwanted upsetting memories
  • Flashbacks
  • Nightmares
  • Emotional distress when recalling the incident
  • A physical reaction in response to triggers

Criterion C

The individual must also demonstrate marked avoidance of trauma-related triggers and events after the initial trauma has occurred. This may include the evasion of thoughts about the incident or people, places, or activities that remind them of it in some way.

Criterion D

In this category, the individual must experience at least two of the criteria to continue in the process towards a possible diagnosis. First, they must have negative thoughts or feelings that started or became worse after the trauma. Second, those thoughts or feelings must have changed based on:

  • Their inability to recall specific aspects of the event
  • Overtly negative thoughts about themselves
  • Negative affect
  • Decreased interest in activities once enjoyed
  • Feelings of isolation
  • Exaggerated self-blaming for the trauma that occurred

Criterion E

The individual must experience at least two of the criteria in this category as well to be considered for a PTSD diagnosis. First, they must experience some form of arousal or reaction that started or became worse after the trauma. This could include:

  • Risky and/or destructive behavior
  • Hypervigilance
  • A heightened startle reflex
  • Trouble sleeping
  • Difficulty concentrating
  • Irritability
  • Aggression

Second, these feelings must be different from those that may have been felt prior to the trauma.

Criteria F–H

To meet these three criteria, the individual must have been experiencing symptoms for more than a month. These may create a level of distress or functional impairment, and they must not be related to any form of medication, substance use, or other illness.

Types of PTSD

If a provider determines that a diagnosis of PTSD applies, they may also decide whether a subtype of the disorder is applicable. Subtypes of PTSD include:

  • Dissociative specification, which means that the individual meets all of the required criteria discussed above, but also experiences either depersonalization or derealization. These additional symptoms must be considered severe.
  • Delayed onset specification, which means that the symptoms that fit a PTSD diagnosis do not present until approximately six months or more after the trauma occurred. (With classic PTSD, symptoms usually present within three months of the event.) In this situation, the individual may start to feel some of the emotions and symptoms immediately, but full onset takes longer. As a result, they may be delayed in receiving an official PTSD diagnosis.

Treatment options for PTSD

Effective treatment for PTSD is possible, even years after the event has occurred. Since aggressive or risky behavior, substance use issues, and suicidal thoughts and behaviors can be symptoms of post-traumatic stress disorder, seeking professional help is usually important. Treatment typically consists of some form of psychotherapy, sometimes in tandem with medication. 

If you or someone you know is experiencing suicidal thoughts or behaviors, seek help immediately. The National Suicide Prevention Lifeline can be reached 24/7 by dialing 988.

One form of therapy commonly used to treat PTSD is cognitive behavioral therapy, or CBT. A cognitive behavioral therapist can help an individual learn to recognize and shift distorted thoughts about the event they experienced and learn healthy coping mechanisms for dealing with symptoms. 

Eye movement desensitization and reprocessing (EMDR) is another type of therapy that may be suggested for individuals with PTSD. It involves a therapist guiding a client through a verbal recollection of the traumatic event while having them make specific eye movements. Other types of therapy may also be recommended; meeting with a therapist for an evaluation is generally the best way to find out which type of treatment might be best for the symptoms you’re experiencing.

Seeking professional support for PTSD symptoms

If you’re experiencing symptoms of PTSD or another mental health disorder, support is available. Meeting with a therapist or other qualified mental health care provider is typically a recommended first step, as they can evaluate your symptoms and suggest the appropriate treatment. If you’d prefer to meet with someone in person, you can search for a provider in your local area. If you’d feel more comfortable meeting with someone from the comfort of your own home or somewhere else you have a reliable internet connection, you might consider online therapy. 

Virtual therapy is often a more cost-effective option, and it’s more convenient for those who can’t easily leave home, have trouble locating a provider in their area, or experience anxiety at the thought of meeting with someone in person. With an online therapy platform like BetterHelp, you can get matched with a licensed therapist who you can meet with via phone, video call, and/or online chat to address the challenges you may be facing. Research suggests that online therapy can offer similar benefits to in-person sessions, with one study indicating that it can be “a viable treatment alternative for PTSD” in particular.

Takeaway

PTSD is a serious mental health condition that may manifest as intense anxiety symptoms after undergoing or witnessing a traumatic event. In order to receive a clinical PTSD diagnosis, an individual must meet certain criteria as outlined in the DSM-V. Effective treatment for this disorder is available and typically consists of some form of psychotherapy, sometimes in combination with medication.
