Trauma

The post-traumatic pattern: how it works, how it shows up, what helps.

Reviewed by Shariq Refai, MD, MBA

Trauma is upstream of more diagnoses than most people realize: PTSD, of course, but also a significant fraction of anxiety, depression, substance use, and dissociative presentations. This hub exists to give the post-traumatic cluster a single clinical landing page and to clarify what trauma-specific treatment actually involves.

Trauma is upstream of more diagnoses than most people realize. It's the obvious driver of PTSD and acute stress disorder, but it's also a major contributor to anxiety disorders, depressive disorders, dissociative disorders, substance use disorders, and several personality disorder presentations.

The post-traumatic cluster, hyperarousal, intrusive memories, avoidance, numbing, triggers, sleep disturbance, has its own logic. Treating it as ordinary anxiety usually doesn't work. Treating it as trauma usually does.

This hub maps the conditions, symptoms, and treatments where trauma is central. The trauma-specific treatments are well-studied and reliably effective when applied to the right cluster.

Conditions

Condition

Post-traumatic stress disorder

What PTSD is, the four symptom groups, why trauma stays stuck, and how trauma-focused treatment helps.

Strong Condition

Acute stress disorder

A trauma-related condition that can appear in the days after a traumatic event, with symptoms like PTSD that last from 3 days to 1 month.

Mixed Condition

Adjustment disorder

Emotional or behavioral symptoms in response to a clear stressor, more than ordinary stress but not major depression.

Mixed Condition

Complex PTSD

A trauma diagnosis in the WHO's ICD-11 that can follow prolonged, repeated trauma.

Mixed Condition

Dissociative identity disorder

What dissociative identity disorder actually is under DSM-5-TR, why social media misrepresents it, and what evidence-based phase-based treatment looks like.

Mixed Condition

Dissociative amnesia

What dissociative amnesia is, how it differs from organic memory loss and malingering, and what evidence-based treatment looks like.

Mixed Condition

Depersonalization-derealization disorder

What depersonalization-derealization disorder is, what triggers it, and what treatment helps.

Treatment Overview

Trauma focused therapies are the first line for PTSD and have the strongest evidence base in the trauma field. Three approaches have the most rigorous trial support: prolonged exposure (PE), cognitive processing therapy (CPT), and EMDR. All three are time limited (typically 12 to 16 weekly sessions) and all three produce durable improvement in the majority of patients who complete a full course. Medication has a secondary role. SSRIs (sertraline and paroxetine have FDA approval) and the SNRI venlafaxine reduce PTSD symptoms. Prazosin specifically helps with trauma related nightmares. Benzodiazepines are generally avoided in acute trauma because some evidence suggests they may worsen long term PTSD outcomes. For complex trauma (developmental trauma, prolonged interpersonal abuse), treatment usually takes longer and may incorporate phase based approaches that build stabilization skills before active trauma processing. Acute stress reactions in the first weeks after a trauma can sometimes be addressed with brief trauma focused CBT, which may reduce the rate of progression to PTSD. Generic talk therapy and reassurance don't move trauma the way the specific trauma focused therapies do.
