What characterizes PTSD?

Post-Traumatic Stress Disorder (PTSD) is characterized by an array of symptoms that follow exposure to a traumatic event. One of the hallmark features of PTSD is the presence of intrusive thoughts or memories related to the trauma, which can present as flashbacks, distressing dreams, or persistent distress when reminded of the event. These intrusive thoughts are distressing and involuntary, significantly impacting the individual's daily life and emotional wellbeing.

While memory loss regarding a traumatic event can occur in some cases, particularly as a dissociative response, it is not a defining characteristic of PTSD. Instead, individuals with PTSD often have vivid recollections of the trauma rather than memory loss. Sustained euphoria is not a typical symptom of PTSD; rather, individuals may experience heightened anxiety, depression, or emotional numbing. Increased sociability also does not align with PTSD symptoms, as many individuals with PTSD may withdraw socially or avoid reminders of the trauma. Thus, recurring intrusive thoughts of a traumatic event is the most accurate characterization of PTSD.
