Post Traumatic Stress Disorder

According to the National Institute of Mental Health, Post-Traumatic Stress Disorder, abbreviated PTSD, is an anxiety disorder that can develop after exposure to a terrifying event or ordeal in which grave physical harm occurred or was threatened. Traumatic events that may trigger PTSD include violent personal assaults, natural or human-caused disasters, accidents, or military combat. The more frequent or severe the traumatic experience, the more drastic the symptomes.

Signs and Symptoms:

People with PTSD have persistent frightening thoughts and memories of their ordeal and feel emotionally numb, especially with people they were once close to. They may experience sleep problems, feel detached or numb, or be easily startled. Many victims lack a sense of basic trust and a sense of hopelessness, often leading to learned helplessness. This is when a person feels that they have no control over the things that happen to them, so they might as well accept it. Virtually any trauma, defined as an event that is life-threatening or that severely compromises the emotional well-being of an individual or causes intense fear, may cause PTSD. (MedicineNet.com)

Three groups of symptoms are required to diagnose a patient with PTSD.

  1. Recurrent re-experiencing of the trauma (for example, troublesome memories, flashbacks that are usually caused by reminders of the traumatic events, recurring nightmares about the trauma and/or dissociative reliving of the trauma)
  2. Avoidance to the point of having a phobia of places, people, and experiences that remind the sufferer of the trauma and a general numbing of emotional responsiveness
  3. Chronic physical signs of hyperarousal, including sleep problems, trouble concentrating, irritability, anger, poor concentration, blackouts or difficulty remembering things, increased tendency and reaction to being startled, and hypervigilance to threat.

There are four types of PTSD:
  • Acute Stress Disorder- symptoms occur within four weeks of the traumatic event and last for more than 2 days, but less than 4 weeks.
  • Acute PTSD- symptoms last for more than 4 weeks.
  • Delayed Onset PTSD- may not appear until years after the initial traumatic experience.
  • Chronic PTSD- symptoms last for more than 90 days. You will likely experience lapses in symptoms for a number of days or weeks in a row, but your symptoms will always return.

PTSD is a disease that can affect dogs as well.
Man experts believe that the Fort Hood shooter, an army psychologist that treated soldiers with PTSD, was himself a victim of the disorder.






Examples of traumatic events that could cause PTSD-
fighting in war
sexual abuse
physical abuse
accident or disaster survivors
living in violent neighborhoods

Many people that suffer from PTSD will become addicted to some form of drug (ex. cocaine) to help cope with their nightmares.

Soldiers returning from war have been known to use dogs as a form of treatment for PTSD. Dogs that are used are often certified therapy dogs. They tend to lift spirits and help owners feel less stressed.
