The easiest way to prove PTSD resulting from a car accident is to be formally diagnosed with the condition by a medical doctor or mental health provider. PTSD treatment can include both therapies focused on confronting the traumatic memory and working through the beliefs associated with the experience and prescription medication in some circumstances that can reduce the mental health conditions associated with PTSD, such as anxiety and depression. To diagnose PTSD, a medical doctor may perform a physical exam to ensure that no physical injuries are causing the condition. A psychological examination may determine if your symptoms align with the diagnostic criteria for the condition as listed in the Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association. Suppose you have not obtained a formal diagnosis of PTSD. In that case, you can often still seek compensation for the psychological impacts of your injury through witness testimony from your employer, family, or friends as to how the emotional trauma has affected your ability to work, socialize, or maintain the responsibilities of your day-to-day life.
