If the International Classification of Diseases (ICD) and the Diagnostic and Statistical Manual (DSM) were reorganized through an interpersonal neurobiology (IPNB) lens, an astonishingly large portion of it might fall under trauma or trauma-related disorders, making them thin volumes. This is because IPNB views trauma as a significant disruptor of the nervous system’s regulation and integration, affecting physical, emotional, and relational health. Here’s how this might look:

Trauma at the Root of Dysregulation

• Acute trauma (e.g., physical injuries, assault, accidents).
• Chronic trauma (e.g., neglect, abuse, systemic oppression, or ongoing stressors).
• Relational trauma (e.g., attachment wounds, betrayals, neglect from caregivers).
• These experiences disrupt the nervous system’s ability to achieve homeostasis, which IPNB views as the foundation of health.

Trauma and Physical Health

IPNB acknowledges the mind-body connection, emphasizing that trauma is stored not just psychologically but also physiologically. Many physical health issues might then be classified as trauma-related, such as:

• Chronic pain conditions (e.g., fibromyalgia, irritable bowel syndrome).
• Autoimmune disorders (e.g., lupus, rheumatoid arthritis).
• Cardiovascular issues (e.g., hypertension, heart disease) from prolonged dysregulation.
• Endocrine disorders (e.g., adrenal fatigue, thyroid issues) from prolonged stress and trauma responses.

Trauma and Mental Health

Most mental health diagnoses in the ICD and DSM might be grouped under trauma, as trauma is a primary dysregulator of neural integration:

• Anxiety disorders (e.g., generalized anxiety, panic disorder).
• Mood disorders (e.g., depression, bipolar disorder).
• Personality disorders, which IPNB would likely view as maladaptive survival adaptations to trauma.
• Addiction and substance use disorders, reframed as coping mechanisms for unresolved pain and dysregulation.

Intergenerational and Cultural Trauma

IPNB also highlights epigenetics and the impact of intergenerational trauma:

• Conditions influenced by epigenetic changes due to trauma.
• Social and cultural traumas (e.g., systemic racism, colonization, war) with significant health impacts.

Trauma and Relational Health

A reorganization might also emphasize disorders rooted in attachment and relational dynamics, such as:

• Attachment disorders (e.g., reactive attachment disorder, disorganized attachment).
• Disorders affecting relational capacity, such as some features of autism or social anxiety, reframed as adaptations to safety-seeking behaviors.

Reframing the Entire ICD and DSM

• Instead of labeling disorders by their symptoms, an IPNB-informed ICD and DSM might group them by the degree and type of nervous system dysregulation, the underlying trauma history, and the individual’s capacity for integration.
• For example, many conditions now seen as distinct (e.g., PTSD, depression, IBS) might be grouped under “Trauma-Induced Dysregulation Disorders.”

Bottom Line:
If the ICD and DSM were reorganized with an IPNB lens, trauma would be recognized as a primary root cause of a vast range of conditions, encompassing both physical and mental health. This shift would likely reframe the majority of the ICD and DSM as trauma-related, focusing on dysregulation, integration, and relational disruption rather than isolated symptoms.
