Here Is What the Clinical Science Actually Says.
Your adult child may have told you they have Complex Post-Traumatic Stress Disorder, or CPTSD. They may have said you caused it. Before accepting or rejecting that claim, you need to know what the clinical standard actually requires.
The DSM-5-TR stands for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision. It is published by the American Psychiatric Association. It is the peer-reviewed standard used by psychiatrists, psychologists, and licensed clinicians in the United States to diagnose and treat mental health conditions.
PTSD stands for Post-Traumatic Stress Disorder.
CPTSD stands for Complex Post-Traumatic Stress Disorder.

Criterion A requires exposure to actual or threatened death, serious injury, or sexual violence.
Then the DSM-5-TR requires measurable symptoms across four additional categories: intrusion, avoidance, cognitive/mood changes, and arousal changes. These symptoms must last more than one month, cause clinically significant impairment, and not be caused by substances.

The DSM-5-TR makes a primary distinction regarding the onset of posttraumatic stress disorder for children six years of age and younger. This distinction is separate from the adult criteria.
For children six years of age and younger, posttraumatic stress disorder can occur at any age beginning after the first year of life. Children six years of age and younger may develop posttraumatic stress disorder as a result of severe emotional abuse, such as the threat of abandonment, which the child can perceive as life-threatening.
Criterion A requires exposure to actual or threatened death, serious injury, or sexual violence. This exposure can occur by directly experiencing the event, witnessing the event in person as it occurred to others, especially primary caregivers, or learning that the traumatic event occurred to a parent or caregiving figure.
Criterion B requires the presence of one or more intrusion symptoms. Spontaneous and intrusive memories may not necessarily appear distressing and may be expressed as play reenactment. Children may report recurrent frightening dreams without recognizable content. Dissociative reactions can occur on a continuum and may be expressed as trauma-specific reenactment during play. Young children might not manifest fearful reactions at the time of exposure or during reexperiencing, and they may focus on imagined interventions in their play or storytelling.
Criterion C requires at least one symptom representing either persistent avoidance of stimuli associated with the traumatic event or negative alterations in cognitions and mood. Because young children have limitations in expressing thoughts or labeling emotions, negative alterations in cognition and mood primarily involve mood changes. Symptoms include efforts to avoid activities, places, physical reminders, people, or conversations associated with the trauma. Additional symptoms include a substantially increased frequency of negative emotional states, socially withdrawn behavior, persistent reduction in the expression of positive emotions, or markedly diminished interest in significant activities, which includes the constriction of play. In addition to exhibiting avoidance, children may become preoccupied with reminders of the trauma. Parents may report a wide range of emotional or behavioral changes in young children.
Criterion D requires two or more alterations in arousal and reactivity. These alterations include hypervigilanceA heightened state of alertness and scanning caused by traum... More, an exaggerated startle response, problems with concentration, sleep disturbances, and irritable behavior or angry outbursts, which can manifest as extreme temper tantrums.
Criterion E requires that the duration of the disturbance is more than one month.
Criterion F dictates that the disturbance must cause clinically significant distress or impairment in school behavior or in relationships with parents, siblings, peers, or other caregivers.
Criterion G requires that the disturbance is not attributable to the physiological effects of a substance or another medical condition.
When children experience chronic circumstances of trauma, they may not be able to identify the specific onset of their symptomatology. The onset for children six years of age and younger can also be categorized with the specifier "with delayed expression." This specifier applies if the full diagnostic criteria are not met until at least six months after the event, although the onset and expression of some symptoms may be immediate.

The Diagnostic and Statistical Manual of Mental Disorders attributes conditions stemming from severe social neglect to distinct diagnoses, specifically Reactive Attachment Disorder and Disinhibited Social Engagement Disorder.
The DSM-5-TR does address neglect. It does not ignore it. It categorizes it under its own diagnoses with their own criteria. It does not call it CPTSD. It does not place it under PTSD.

An MA-level therapist (not a psychiatrist, not a PhD psychologist) created a framework that expands CPTSD far beyond what the DSM-5-TR recognizes. Below are the specific claims compared directly against what the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision states.
The key and most fundamental difference is that this framework categorizes Complex Post-Traumatic Stress Disorder as a distinct diagnosis and an attachment disorder that can develop from ongoing childhood abuse or solely from emotional neglect. Conversely, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision does not recognize Complex Post-Traumatic Stress Disorder as an official diagnosis. The manual requires exposure to actual or threatened death, serious injury, or sexual violence to diagnose Posttraumatic Stress Disorder, while it attributes conditions stemming from severe social neglect to separate diagnoses, specifically Reactive Attachment Disorder and Disinhibited Social Engagement Disorder.
Secondary differences stem from this conceptual divide. The framework characterizes the condition using mechanisms such as an overgrown "inner critic" and emotional flashbacks that often lack visual or memory components, classifying trauma defenses into fight, flight, freeze, and fawn categories. The Diagnostic and Statistical Manual of Mental Disorders characterizes flashbacks as dissociative reactions involving intrusive memories wherein the individual feels or acts as if the traumatic event were actively recurring, and it outlines trauma responses under marked alterations in arousal and reactivity without recognizing the fawn response.
This is the process, step by step. No clinician is involved at any point.
