CPTSD Symptoms: What Complex Trauma Looks Like in Adults

CPTSD stands for complex post-traumatic stress disorder. The term describes the effects of prolonged trauma, often beginning in childhood, and involving harm from someone a person trusted. Complex PTSD includes the symptoms of post-traumatic stress disorder (PTSD), along with changes in how a person manages emotions, views themselves, and relates to others (National Center for PTSD, 2026a).

This article explores CPTSD symptoms in adults, how CPTSD differs from PTSD, symptoms that are easy to miss, and why trauma and substance use so often occur together.

CPTSD Symptoms in Adults

Complex PTSD (CPTSD) includes the core symptoms of PTSD, plus several others (National Center for PTSD, 2026a). The lists below separate the two. Only a mental health professional can determine whether symptoms meet the criteria for either condition (NIMH, 2023).

Symptoms of Both PTSD and CPTSD

• Reliving the event: Experiencing flashbacks, distressing memories, or nightmares, sometimes with physical reactions such as a racing heart or sweating.
• Avoidance: Avoiding people, places, objects, activities, or situations that serve as reminders of the trauma.
• Anxiety: Feeling on edge, being easily startled, trouble sleeping, difficulty concentrating, and increased irritability.
• Negative thoughts and feelings: Blaming yourself or others, persistent fear, feelings of guilt or shame, and withdrawal from previously enjoyed activities (NIMH, 2023).

Symptoms That Set CPTSD Apart

• Difficulty managing emotions: Feeling overwhelmed by intense emotions or struggling to regulate emotional responses.
• Negative self-perception: Persistent feelings of worthlessness, shame, or failure.
• Relationship difficulties: Struggling to trust others, withdrawing from relationships, or feeling emotionally distant.
• Disconnection or dissociation: Feeling detached from yourself or your surroundings, or having difficulty staying present (National Center for PTSD, 2026a).

PTSD is diagnosed when symptoms persist for more than a month and affect daily life, work, and relationships (NIMH, 2023). If you are having thoughts of suicide, call or text the 988 Suicide and Crisis Lifeline at 988. In a life-threatening emergency, call 911.

CPTSD vs. PTSD: What Is the Difference?

PTSD and CPTSD both develop after trauma and share the same core symptoms: reliving the trauma, avoiding reminders of it, and feeling constantly on guard.

What Is CPTSD?

CPTSD is an acronym for complex post-traumatic stress disorder, also sometimes called C-PTSD. "Complex" denotes the recurrent, personal nature of the trauma and the broader array of symptoms that can result from it (National Center for PTSD, 2026a).

Is CPTSD an Official Diagnosis?

Complex PTSD was recognized as a separate diagnosis in the World Health Organization's International Classification of Diseases in 2022 (ICD-11). The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR), commonly used in the United States, does not list CPTSD as a separate diagnosis. Instead, some symptoms associated with CPTSD may be captured under a PTSD diagnosis or other diagnoses (National Center for PTSD, 2026a).

What Kind of Trauma Leads to CPTSD?

CPTSD is often associated with prolonged or repeated trauma, particularly experiences involving interpersonal harm, such as childhood abuse, neglect, or abuse by someone a person depended on. This is not always the case, though. People respond to trauma differently: one person may experience childhood abuse and have few lasting symptoms, while another person may have lasting effects on their well-being and relationships after a single traumatic event (National Center for PTSD, 2026a).

Difficult childhood experiences are common. In an analysis of U.S. adults, nearly two thirds reported at least one adverse childhood experience, such as abuse, neglect, or exposure to violence before age 18, and about 17%, or roughly 1 in 6, reported four or more (Swedo et al., 2023). These experiences can contribute to health and mental health challenges, but they do not mean someone will develop CPTSD.

Trauma Symptoms That Are Easy to Miss

Some symptoms of trauma do not look like flashbacks. They may be mistaken for everyday stress, a medical problem, or a personality trait.

Can Trauma Cause Memory Loss?

Trauma can affect memory. Trouble remembering key parts of the traumatic event is a recognized symptom of PTSD (NIMH, 2023). Some people with complex trauma may also experience dissociation, which can make it hard to stay in the present moment because they feel disconnected from themselves and their surroundings, even after the traumatic event (National Center for PTSD, 2026a). If memory gaps or periods of feeling disconnected are affecting your daily life, bring them up with a health care provider.

What Is a Common Physical Reaction to Trauma?

Trauma can affect the body as well as the mind. Common physical reactions include a pounding heart, rapid breathing, and shakiness, along with stomach upset, changes in appetite, difficulty sleeping, and persistent fatigue. Some people get severe headaches when they think about the event, and existing medical problems can get worse (National Center for PTSD, 2026b).

Why Does Trauma Make Relationships Harder?

Because complex trauma often includes being harmed, hurt, or betrayed, it can make it difficult for a person to trust and feel safe with others and have healthy relationships. The person may pull away from relationships, avoid contact, or try to control everything themselves (National Center for PTSD, 2026a, 2026b).

Trauma and Substance Use: Why People Self-Medicate

People with trauma may turn to alcohol or drugs to try to numb the memories and manage the associated thoughts and feelings. Substance use may offer temporary relief from suffering, but it can also create further problems (National Center for PTSD, 2026b).

PTSD and substance use disorders (SUDs), which involve ongoing problems with alcohol or drug use, often occur together. In a large national study, about 45% of people who had PTSD at some point in their lives also met the criteria for an alcohol or other substance use disorder. On average, people living with both conditions face more medical, legal, financial, and social challenges than people living with either condition alone (Norman et al., 2025).

Treating Trauma and Substance Use Together

Some treatment approaches have required people to stop using substances before beginning trauma-focused therapy. Research suggests that treatment does not always need to wait until a person achieves abstinence. With appropriate clinical support, people experiencing both PTSD and substance use disorders can benefit from trauma-focused treatment, and integrated approaches that address both conditions at the same time show the greatest benefit (Norman et al., 2025).

At Sunview Wellness, trauma is treated alongside substance use, starting with safety and stability. Therapy may include Internal Family Systems (IFS) to understand protective patterns, dialectical behavior therapy (DBT) to build coping skills for managing strong emotions, psychodrama to work through experiences with guided role-play, and cognitive behavioral therapy (CBT) to identify and change unhelpful thoughts.

Psychiatric evaluation and medication management are part of every program. If substance use brings you to treatment, mention trauma symptoms during your assessment, even if you have not connected the two. A clinician can then plan care that addresses both, which is the focus of our dual diagnosis treatment.
