Post-Traumatic Stress Syndrome, shortened to PTSS, formerly known as Post-Traumatic Stress Disorder (PTSD), is a condition of persistent mental and emotional stress occurring as a result of injury or severe psychological shock. It is often received from either a single traumatic event that is witnessed or experienced to a series of enduring events subjected to a long period of time.

Causes and Symptoms

Although every person reacts to trauma differently, victims of PTSS have faced a shocking event or series of events, which include crimes like sexual or physical assaults, the death of a loved one, the effects of natural disasters, and the horrors of war. Symptoms include reliving the ordeal or projecting it in their surrounding environment, the avoiding of people or places that remind them of their traumatic event, increased emotions like fits of anger and sadness that are often triggered, and, in some cases, some depression.

On Criminal Minds

PTSS has referenced multiple times on the show and has been a driving force of criminals and other characters. Throughout the series, it is most commonly referred to by its former name, PTSD.

The following characters on the show suffer from PTSS:



  • Roy Woodridge's severe PTSS mostly stemmed from a single event where he disarmed and killed a child soldier in defense of his best friend. He would later believe he was still in the battle zone when committing his kills but made sure the children around him were safe.
  • After witnessing his fiancée Vickie being gang-raped and murdered, Jonny McHale's PTSS would lead him to target members of the gang responsible for Vickie's murder.
  • Ian Coakley's PTSS was a contributing factor to his delusions, where an accidental car crash caused by him that resulted in his wife's death was actually an intentional murder by a conjured-up driver.
  • Darrin Call would stay traumatized after witnessing his father's crimes against young boys.
  • Miranda Jakar developed PTSS after witnessing the Srebrenica massacre as a teenage girl, causing her to kill whenever she was reminded of the incident in some way.
  • Similar to Roy Woodridge, Luke Dolan would develop this mental illness while in the war, specifically when he was forced to kill two children.
  • Matthew Downs was traumatized after his years as a Marine, which caused him to retaliate against the American government and eventually become a homegrown terrorist.
  • William Taylor suffered from some aspects of PTSS due to the abduction and murder of his daughter Tatiana. Although not fully diagnosed, the alleged PTSS could have been the driving force in his kills.
  • Jake Logan was traumatized by his participation in a drone strike that mistakenly killed over 300 Afghani school children, mistaking the school for a terrorist training camp.
