To "prove" PTSD, you need a formal diagnosis from a mental health professional (psychiatrist, psychologist) by demonstrating specific symptoms (re-experiencing, avoidance, negative mood/cognition, hyperarousal) for over a month, impacting daily life, often using structured interviews like the CAPS-5 or checklists like the PCL-5, after detailing your traumatic event exposure. The "proof" comes from this clinical assessment, not self-declaration, though self-screening tools can help you prepare.
For physical health problems, this could include labs (like bloodwork), tests (like an x-ray, scan or biopsy) or a physical exam. For PTSD, an assessment includes answering questions about your thoughts, feelings and behaviors. PTSD is most often diagnosed, or confirmed, by a mental health provider.
If you think you're experiencing post-traumatic stress disorder (PTSD) or complex post-traumatic stress disorder (CPTSD), we strongly encourage you to visit your GP and discuss your concerns.

For a PTSD claim as a veteran, you'll need evidence that shows a current PTSD diagnosis, an in–service incident that caused or worsened your PTSD, and a nexus between your PTSD and your service. Failure to provide this evidence can result in a VA Disability claim denial.
The VA frequently denies PTSD claims due to a lack of evidence establishing a service connection between a veteran's PTSD and their military service. A veteran can strengthen their claim on appeal by consulting a medical professional to obtain a nexus letter.
Criteria for Diagnosis
To receive a diagnosis of PTSD, a person must have at least one re-experiencing symptom, at least three avoidance symptoms, at least two negative alterations in mood and cognition, and at least two hyperarousal symptoms for a minimum of one month.
Directly experiencing the traumatic event(s). Witnessing, in person, the event(s) as it occurred to others. Learning that the traumatic event(s) occurred to a close family member or close friend. In cases of actual or threatened death of a family member or friend, the event(s) must have been violent or accidental.
We look at some of these conditions in more detail below.
All of them are a natural outcome of fearful situations or extended periods of trauma. With Post Traumatic Stress Disorder (PTSD) or C-PTSD, they can leave a lasting legacy and become a recurrent behaviour. This article explains what Fight, Flight, Freeze, Fawn and flop are.
PTSD is diagnosed by a psychiatrist through a mental health assessment. Your GP should carry out an initial assessment to decide what care you need. Your assessment should include information about your physical needs, mental needs, social needs, and risk.
The 5 core signs of PTSD fall into categories: Re-experiencing (flashbacks, nightmares), Avoidance (staying away from reminders), Negative Changes in Mood & Cognition (guilt, detachment, loss of interest), Changes in Arousal & Reactivity (hypervigilance, easily startled, irritability), and sometimes Physical Symptoms like chronic pain or headaches, all stemming from a trauma, though the exact symptoms vary.
Several self-assessments for PTSD can be found online. If you frequently find yourself asking "do I have PTSD," these tests may help you gain awareness of your PTSD symptoms, but only a licensed mental health professional can make a mental health diagnosis.
Though they cannot make a diagnosis, they usually have pathways into services better equipped to provide specialised support. This is usually in the form of a referral – which may require a written letter to a psychiatrist. Only a psychiatrist can make an official PTSD diagnosis.
Generally, PTSD symptoms are grouped into four types: intrusive memories, avoidance, negative changes in thinking and mood, and changes in physical and emotional reactions. Symptoms can vary over time or vary from person to person.
In addition to the symptoms that accompany PTSD, changes occur in the body at the level of cells and molecules, some of which can be identified from within blood.
abuse, including childhood or domestic abuse. exposure to traumatic events at work, including remote exposure. serious health problems, such as being admitted to intensive care. childbirth experiences, such as losing a baby.
Where trauma is the emotional response to a terrible event, PTSD is a far more severe disorder surrounding the event. Untreated trauma can progress into PTSD. However, proper guidance and care can help to minimize its effects and overall impact. PTSD does not exist without it.
How is PTSD diagnosed? Your doctor will ask you about your symptoms and whether you have experienced any trauma, and if necessary, work with you to build a mental health treatment plan. This is a plan that maps out your treatment goals and includes the services and resources available to you.
A mental health professional—such as a psychiatrist, psychologist, or clinical social worker—can determine whether symptoms meet the criteria for PTSD. To be diagnosed with PTSD, an adult must have all of the following for at least 1 month: At least one re-experiencing symptom. At least one avoidance symptom.
Avoidance and emotional numbing
This usually means avoiding certain people or places that remind you of the trauma, or avoiding talking to anyone about your experience. Many people with PTSD try to push memories of the event out of their mind, often distracting themselves with work or hobbies.
The PSS-I is a 17-item semi-structured interview useful for assessment and diagnosis. Respondents with a known trauma history identify a single traumatic event that causes the most current distress. The presence and severity of associated DSM-IV PTSD symptoms experienced in the past two weeks are assessed.
These triggers can be external, such as sights, sounds, smells, or locations that are associated with the trauma. They can also be internal, such as certain thoughts, emotions, or physical sensations that are similar to those experienced during the traumatic event.
Having recurrent thoughts about death or a wish not to wake up is considered a serious symptom for the 70% rating. The presence of these thoughts—not necessarily an intent to act on them—should be disclosed, as it is an important indicator of mental health severity for the VA.
