Posttraumatic stress disorder in the context of "Interoception"

Agoraphobia is an anxiety disorder characterized by symptoms of anxiety in situations where the person perceives their environment to be unsafe with no way to escape. These situations can include public transit, shopping centers, crowds and queues, or simply being outside their home on their own. Being in these situations may result in a panic attack. Those affected will go to great lengths to avoid these situations. In severe cases, people may become completely unable to leave their homes.

Agoraphobia is believed to be due to a combination of genetic and environmental factors. The condition often runs in families, and stressful or traumatic events such as the death of a parent or being attacked may be a trigger. In the DSM-5, agoraphobia is classified as a phobia along with specific phobias and social phobia. Other conditions that can produce similar symptoms include separation anxiety, post-traumatic stress disorder, and major depressive disorder. The diagnosis of agoraphobia has been shown to be comorbid with depression, substance abuse, and suicidal ideation.Without treatment, it is uncommon for agoraphobia to resolve. Treatment is typically with a type of counselling called cognitive behavioral therapy (CBT). CBT results in resolution for about half of people. In some instances, those with a diagnosis of agoraphobia have reported taking benzodiazepines and antipsychotics. Agoraphobia affects about 1.7% of adults. Women are affected about twice as often as men. The condition is rare in children, often begins in adolescence or early adulthood, and becomes more common at age 65 or above.

A trauma trigger is a psychological stimulus that prompts involuntary recall of a previous traumatic experience. The stimulus itself need not be frightening or traumatic and may be only indirectly or superficially reminiscent of an earlier traumatic incident, such as a scent or a piece of clothing. Triggers can be subtle, individual, and difficult for others to predict. A trauma trigger may also be called a trauma stimulus, a trauma stressor or a trauma reminder.

The process of connecting a traumatic experience to a trauma trigger is called traumatic coupling. When trauma is "triggered", the involuntary response goes far beyond feeling uncomfortable and can feel overwhelming and uncontrollable, such as a panic attack, a flashback, or a strong impulse to flee to a safe place. Avoiding a trauma trigger, and therefore the potentially extreme reaction it provokes, is a common behavioral symptom of posttraumatic stress disorder (PTSD) and post-traumatic embitterment disorder (PTED), a treatable and usually temporary condition in which people sometimes experience overwhelming emotional or physical symptoms when something reminds them of, or "triggers" the memory of, a traumatic event. Long-term avoidance of triggers increases the likelihood that the affected person will develop a disabling level of PTSD. Identifying and addressing trauma triggers is an important part of treating PTSD.

Wounded in action (WIA) describes combatants who have been wounded while fighting in a combat zone during wartime, but have not been killed. Typically, it implies that they are temporarily or permanently incapable of bearing arms or continuing to fight. Generally, the Wounded in Action are far more numerous than those killed. Common combat injuries include second and third-degree burns, broken bones, shrapnel wounds, brain injuries, spinal cord injuries, nerve damage, paralysis, loss of sight and hearing, post-traumatic stress disorder (PTSD), and limb loss.

For the U.S. military, becoming WIA in combat generally results in subsequent conferral of the Purple Heart, because the purpose of the medal itself (one of the highest awards, military or civilian, officially given by the American government) is to recognize those killed, incapacitated, or wounded in battle.

Reduced affect display, sometimes referred to as emotional blunting or emotional numbing, is a condition of reduced emotional reactivity in an individual. It manifests as a failure to express feelings either verbally or nonverbally, especially when talking about issues that would normally be expected to engage emotions. In this condition, expressive gestures are rare and there is little animation in facial expression or vocal inflection. Additionally, reduced affect can be symptomatic of autism, schizophrenia, depression, post-traumatic stress disorder, depersonalization-derealization disorder, schizoid personality disorder or brain damage. It may also be a side effect of certain medications (e.g., antipsychotics and antidepressants).

However, reduced affect should be distinguished from apathy and anhedonia, which explicitly refer to a lack of emotional sensation.
