Block, MD on February 19, 2021 Print Arief Juwono / Moment / Getty Images Subthreshold PTSD refers to the experiencing of some post-traumatic stress disorder (PTSD) symptoms after a traumatic event, but not quite enough to meet criteria for a PTSD diagnosis. 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 event Reliving the traumatic event as if it were happening again (flashbacks) Upsetting dreams about the traumatic event Severe 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 event Avoiding 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 behavior Always being on guard for danger Overwhelming guilt or shame Self-destructive behavior, such as drinking too much or driving too fast Trouble concentrating Trouble sleeping Being 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. PTSD symptoms can vary in intensity over time. 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.
