Post-Traumatic Stress Disorder Library
The Post-Traumatic Stress Disorder Library provides reliable and quality assessed information. This information comes from peer-reviewed systematic reviews covering over 200 topics on post-traumatic stress disorder, also known as PTSD. These topics include signs and symptoms, treatments, diagnosis, causes, outcomes, co-occurring mental and physical disorders, incidence and prevalence, the physical features of the disorder, and insights for families. Topics can be accessed by clicking on the links above. Or use the drop-down menu or search bar on the left or click on the tabs below.
There are two levels of information on each topic. The first is a Factsheet that provides general information describing the topic and the evidence that is available on that topic. The second is a Technical Commentary that provides more detailed information, including the topic’s background, methods, detailed results, and links to references. Printable PDFs of factsheets and technical tables are available to download from each topic page.

Diagnosis and assessment
A person needs to have been exposed to at least one trauma to receive a PTSD diagnosis. Common traumas include being exposed to illnesses, accidents, wars, pandemics, disasters, and violence. The severity of the trauma and its frequency influences the risk of developing PTSD. Whether the trauma is directly or indirectly experienced, such as being a victim of violence or witnessing violence, whether it was committed intentionally or unintentionally, and whether it was interpersonal also influences the risk. Other influencing factors include age, sex, personality traits, social factors, and cognitive and psychological factors. Core symptoms of intrusion, avoidance, hyperarousal, and negative thoughts and mood need to be present for a PTSD diagnosis. Dissociation, anxiety, anger, depression, and distress may also be present. Click on the tabs below to access the information, or navigate through the topics via the section on the left.

Signs and symptoms
This category provides information about the signs and symptoms of PTSD. Common PTSD symptoms include unwanted and upsetting memories, nightmares, flashbacks, emotional distress and physical reactivity after exposure to reminders, which leads to avoidance of these reminders. There may also be symptoms of poor sleep, negative thoughts and mood, depression, anxiety, dissociation, and anger. There may also be problems with cognition, including poor general cognition, memory, attention, executive functioning, social cognition, and difficulty processing new information.

Psychotherapies are considered first-line treatments for PTSD. These include cognitive behavioural therapy (CBT), exposure and cognitive therapies, and eye movement desensitization and reprocessing therapy (EMDR). These are sometimes combined with pharmacological treatments, including antidepressants, which may be administered without accompanying therapies. This category covers both pharmacological and psychological treatments, as well as non-pharmaceutical physical treatments such as transcranial magnetic stimulation (TMS).

Exposure to trauma is required for a diagnosis of PTSD. Traumas include illness, accidents, war and terrorism, pandemics, disasters, and violence and abuse, among others. Risk of PTSD can be influenced by trauma characteristics such as trauma severity and frequency, whether the trauma is experienced directly or indirectly, whether it was intentional or non-intentional, and whether it was interpersonal. Personal characteristics can also determine who will develop PTSD following exposure to trauma. These include certain personality traits, social factors, and cognitive and psychological factors including resilience.
