Subthreshold PTSD can be associated with distress and impairment consistent with what is seen among people with a PTSD diagnosis. To officially have a diagnosis of PTSD, you need to have a certain number of re-experiencing, avoidance, and hyperarousal symptoms.

PTSD Symptoms

PTSD symptoms can begin up to three months after a traumatic event, but sometimes do not appear until years after the event. These symptoms cause significant problems in social or work situations and in relationships. PTSD symptoms are generally grouped into four types: intrusive memories, avoidance, negative changes in thinking and mood, or changes in emotional reactions.

Intrusive Memories

Symptoms of intrusive memories may include:

Recurrent, unwanted distressing memories of the traumatic eventReliving the traumatic event as if it were happening again (flashbacks)Upsetting dreams about the traumatic eventSevere emotional distress or physical reactions to something that reminds you of the event

Avoidance

Symptoms of avoidance may include:

Trying to avoid thinking or talking about the traumatic eventAvoiding places, activities or people that remind you of the traumatic event

Negative Changes in Thinking and Mood

Symptoms of negative changes in thinking and mood may include:

Negative feelings about yourself or other people Inability to experience positive emotions Feeling emotionally numb Lack of interest in activities you once enjoyed Hopelessness about the future Memory problems, including not remembering important aspects of the traumatic event Difficulty maintaining close relationships

Changes in Emotional Reactions

Symptoms of changes in emotional reactions (also called arousal symptoms) may include:

Irritability, angry outbursts or aggressive behaviorAlways being on guard for dangerOverwhelming guilt or shameSelf-destructive behavior, such as drinking too much or driving too fastTrouble concentratingTrouble sleepingBeing easily startled or frightened

Intensity of Symptoms

You may have more PTSD symptoms when you’re stressed in general, or when you run into reminders of what you went through. For example, you may hear a car backfire and relive combat experiences. Or you may see a report on the news about a sexual assault and feel overcome by memories of your own assault.

When to See a Doctor

According to the Mayo Clinic, if you have disturbing thoughts and feelings about a traumatic event for more than a month, if they’re severe, or if you feel you’re having trouble getting your life back under control, talk to your healthcare professional. Get treatment as soon as possible to help prevent PTSD symptoms from getting worse.
