Post-traumatic stress disorder (PTSD) develops after experiencing or witnessing a terrifying, life-threatening, or deeply distressing event (combat, sexual assault, serious accidents, natural disasters, sudden loss, childhood abuse, etc.). Not everyone who goes through trauma gets PTSD about 6–8% of adults will develop it in their lifetime.
The four main symptom clusters (DSM-5 criteria) must last more than one month and cause significant distress or problems in daily life:
- Intrusion symptoms (at least 1 required)
- Repeated, unwanted memories of the event
- Nightmares related to the trauma
- Flashbacks (feeling like the event is happening again)
- Intense distress or physical reactions when reminded of it (racing heart, sweating)
- Avoidance (at least 1 required)
- Deliberately avoiding thoughts, feelings, or conversations about the trauma
- Avoiding people, places, or activities that trigger memories
- Negative changes in mood and thinking (at least 2 required)
- Persistent negative beliefs about yourself or the world (“I’m broken,” “No one can be trusted”)
- Blame of self or others for what happened
- Feeling detached or estranged from others
- Inability to feel positive emotions (numbness)
- Memory gaps about important parts of the event
- Hyperarousal / reactivity changes (at least 2 required)
- Irritable or aggressive behavior
- Reckless or self-destructive behavior
- Being easily startled
- Hypervigilance (constantly “on guard”)
- Problems concentrating
- Sleep disturbances (trouble falling or staying asleep)
Other signs: feeling “on edge” most of the time, survivor’s guilt, loss of interest in life, or physical symptoms like chronic pain or stomach issues without clear medical cause.
Important: Only a qualified mental health professional (psychiatrist, psychologist, or licensed therapist) can diagnose PTSD. Self-diagnosis is not reliable. If several of these symptoms started or worsened after a traumatic event and have lasted longer than a month, seek a proper evaluation. Early treatment (trauma-focused therapy such as CPT, PE, or EMDR, and sometimes medication) works very well.
You’re not weak for having these reactions PTSD is a normal brain response to abnormal events. Help is available and recovery is possible.
