Research indicates that 3.6% of those 18 and older in the United States alone live with post-traumatic stress disorder or PTSD per year. PTSD is considered a common mental health disorder, but there are some misunderstandings about post-traumatic stress disorder and what it is. There are many stereotypes and assumptions made about PTSD. One of the most common assumptions made about PTSD is that it affects adults in the military and does not affect anyone else. This could not be more or false; post-traumatic stress disorder is a disorder that can affect anyone who has experienced a traumatic event, and it affects people of all ages. So, what age group shows the most PTSD? In this article, we will go over the average age of onset for post-traumatic stress disorder and other PTSD statistics.

What Is PTSD?

Post-traumatic stress disorder or PTSD is a mental health condition or disorder that can develop after a traumatic event. Not all, or even most, survivors of traumatic events go on to develop post-traumatic stress disorder, but it is a disorder that is born out of trauma in some people

Symptoms or signs of post-traumatic stress disorder include but are not limited to:

  • Hypervigilance
  • Re-experiencing traumatic events, whether that is through flashbacks, nightmares, or something else
  • Irritability or agitation
  • Trouble sleeping or insomnia
  • Social withdrawal or isolation from others
  • Trouble focusing or concentrating
  • Difficulty trusting other people
  • Emotional detachment
  • Feelings of guilt
  • Self-destructive behaviors

Diagnostically speaking, to be diagnosed with post-traumatic stress disorder, you have to have experienced or witnessed a traumatic event. Symptoms of PTSD must affect your life and ability to function in social relationships or social situations, work, school, self-care, and so on to be diagnosed. It is normal to experience emotional consequences after trauma, but PTSD is more severe, and the impact is long-lasting. The good news is that post-traumatic stress disorder is a treatable condition. There are several studied treatments for post-traumatic stress disorder, including therapies such as cognitive-behavioral therapy or CBT and eye movement desensitization and reprocessing therapy or EMDR. For all information regarding specific treatments and therapies, make sure to speak with a medical or mental health professional who can give you individual medical or mental health advice.

What Age Group Shows The Most PTSD? 

Statistics from the national institute of Mental Health NIMH suggest that individuals aged 45 to 59 have the highest prevalence of post-traumatic stress disorder, followed by those aged 18 to 29. Here are the percentages found in those studies:

  • 4% of People ages 18 through 29 have post-traumatic stress disorder.

  • 3% of those 45 through 59 have post-traumatic stress disorder.
  • 1% of those aged 60 or older have post-traumatic stress disorder.

It is important to note that children can also experience PTSD. Symptoms of PTSD and children can differ from those seen in adulthood with post-traumatic stress disorder PTSD. Though some symptoms are the same, children might experience other symptoms, such as reenacting traumatic events through play. Sources say that, out of the children who experience trauma, the development of post-traumatic stress disorder in kids is more likely to occur in girls than in boys. More specifically, 3%-15% of girls and 1-6% of boys develop PTSD after a traumatic event.
