Approximately 30% of the variance in PTSD is caused by genetics alone. [1] For twins exposed to combat in the Vietnam War, a monozygotic (identical) twin with PTSD was associated with an increased risk of the co-twin having PTSD, as compared to dizygotic (non-identical) twins; [2] additionally, assaultive trauma (compared to non-assaultive trauma) was more likely to exacerbate these effects.
The DSM-5 asserts that PTSD manifests differently in children over six years old than in adults. Specifically that their flashbacks or intrusive memories may be explained by recreating their traumatic event(s) through their play. They may also experience reoccurring nightmares that are indirectly related to the event.
PTSD was classified as an anxiety disorder in the DSM-IV, but has since been reclassified as a "trauma- and stressor-related disorder" in the DSM-5. [1] The DSM-5 diagnostic criteria for PTSD include four symptom clusters: re-experiencing, avoidance, negative alterations in cognition/mood, and alterations in arousal and reactivity. [1] [4]
A revision of DSM-5, titled DSM-5-TR, was published in March 2022, updating diagnostic criteria and ICD-10-CM codes. [91] The diagnostic criteria for avoidant/restrictive food intake disorder was changed, [ 92 ] along with adding entries for prolonged grief disorder , unspecified mood disorder and stimulant-induced mild neurocognitive disorder .

This assessment has evolved since its development in 1985 to include changes made to DSM criteria and to allow for efficiency in assessment. In 1985, Calvin Fredrick worked with the UCLA Trauma Psychiatry Program to develop a measure to screen for PTSD in children and adolescents based on DSM criteria—the UCLA PTSD Reaction Index. [2]
Complex post-traumatic stress disorder (CPTSD, cPTSD, or hyphenated C-PTSD) is a stress-related mental and behavioral disorder generally occurring in response to complex traumas [1] (i.e., commonly prolonged or repetitive exposures to a series of traumatic events, from which one sees little or no chance to escape).
The DSM-5 trait model does not include a domain of anankastia, but in the initial version of the trait model there was a domain of compulsivity that is closely aligned with anankastia. [80] Both the DSM-5 Section III and ICD-11 dimensional trait models are aligned with the FFM.
