Post-Traumatic Stress Disorder (PTSD) is a psychiatric condition that can develop after a person experiences or witnesses a life-threatening or deeply disturbing event. For veterans, these events may include combat exposure, IED blasts, the death of fellow service members, military sexual trauma, or prolonged exposure to high-threat environments.
PTSD is not a sign of weakness. It is a neurobiological response to extreme stress — one that fundamentally alters how the brain processes threat, memory, and emotion.
Core Symptom Clusters
The DSM-5 organizes PTSD symptoms into four categories:
- Intrusion. Unwanted re-experiencing of the traumatic event, including flashbacks, nightmares, and intrusive memories that feel involuntary and vivid.
- Avoidance. Deliberately staying away from people, places, thoughts, or feelings associated with the trauma. Many veterans withdraw from family, crowds, or situations that feel unpredictable.
- Negative alterations in cognition and mood. Persistent feelings of guilt, shame, or blame; emotional numbness; loss of interest in previously enjoyed activities; difficulty experiencing positive emotions.
- Hyperarousal and reactivity. Heightened startle response, hypervigilance, irritability, sleep disturbance, and difficulty concentrating. Veterans may feel constantly on guard even in safe environments.
How PTSD Affects Daily Life
PTSD rarely affects just one area of functioning. Veterans living with PTSD often experience significant disruption across multiple domains — work performance, intimate relationships, parenting, social engagement, and physical health. Many also develop secondary conditions such as depression, anxiety, insomnia, or substance use disorders as a result of untreated or under-treated PTSD.
PTSD and VA Disability
PTSD is one of the most commonly service-connected mental health conditions. To establish service connection, a veteran generally needs a current PTSD diagnosis, documentation of a qualifying in-service stressor, and a medical opinion connecting the two.
The VA rates PTSD under the General Rating Formula for Mental Disorders, using a scale of 0, 10, 30, 50, 70, or 100 percent based on occupational and social impairment.
How an Independent Evaluation Can Help
VA C&P exams are often brief and may not capture the full severity of a veteran’s symptoms — particularly for veterans who minimize their experiences or present well under pressure. An independent forensic psychological evaluation provides a comprehensive, documented assessment of how PTSD is actually affecting your life, which can strengthen an initial claim, support an appeal, or substantiate a request for a rating increase.
