Structural Dissociation, A Framework To Understand Series Of Trauma

Structural dissociation is a theory that explains that severe or chronic trauma, especially in childhood, can result in a division of the self into different parts or subsystems. These parts, including apparently normal parts (ANPs) that help to function in daily life, and emotionally parts (EPs) (that hold trauma, memories, and responses), are not integrated fully and hinder the daily functioning and emotional regulation of a child or an adult. These parts do not merely represent different moods of roles but possess unique ways of thinking, feeling, and behaving.  This theory is often applied in the context of complex trauma, dissociative disorder, and related conditions. The division serves as a psychological mechanism to cope with overwhelming emotional experiences.

In children, this occurs when the child has grown up without emotional support from parents. This can deeply affect a person’s mind and emotions.

When a child has gone through neglect and abuse from narcissistic parents, it creates a type of trauma that is different from a single bad event. This is a series of traumas that comes from constant emotional pain and lack of empathy, instead of a single event.

What is structural dissociation? Getting to know about structural dissociation and its impact on a person is necessary to give psychiatric support to those who are suffering from this problem.

How It All Started?

As a child, you can’t leave or escape all the traumatic episodes, and your mind finds an eternal escape to cope with this constant pain. This is a type of hidden place within your own self, in your psyche, where the pain is stored away.

This is like creating a separate part of yourself that holds all the hurt and anger. Even if you don’t consciously remember these feelings, they are hidden inside you, frozen in time.

Psychology calls this condition or process “structural dissociation”. It is like building walls in your mind to separate and protect yourself from overwhelming emotions. This mechanism helps you survive by keeping the pain locked inside.

People don’t lose touch with reality like in schizophrenia. You still know who you are as one person. But certain triggers, like humiliation or rejection, can make you feel like different “parts” of yourself are taking over. These parts can have their own personalities, emotions, and behaviors. For example, one part might feel like a scared child, while another part feels like an angry teenager.

To simply understand this situation, it is like your mind split into two main parts, on is the “normal self” and the other is “traumatized self. The normal self is the part you show to the public, and it is in control and functional. The “traumatized self” is the hidden part that holds all the pain from past traumas.

On one hand, you look like you have everything together. But insight, you might feel empty, as if life has no meaning and you are just going through the motions. Society might praise you for being strong and functional. But this can even make you more disconnected from your true feelings.

The origin of structural dissociation theory

The theory of structural dissociation originated from the work of Pierre Janet, a French psychologist who studied trauma and dissociation in the late 19th and early 20th centuries. Later, Onno van der Hart, Ellert Nijenhuis, and Kathy Steele expanded on Janet’s ideas to develop the theory of structural dissociation. The theory suggests that personality can be divided into different parts, each with its own functions and memories.

Key Aspects of Structural Dissociation

Division Of The Self

In structural dissociation, a person usually experiences multiple “parts” or “ego states” rather than a single, unified sense of self. This division is manifest in various ways, which affect how a person perceives and interacts with the world.

Response to Trauma

Structural dissociation often arises as a response to severe trauma, especially when the person cannot escape or process the traumatic experience. This response helps the mind to manage the overwhelming emotions that are associated with the trauma.

Types of Structural Dissociation

Structural dissociation can manifest in various forms, but that depends on the severity and type of trauma experienced. The main types include primary, secondary, and tertiary dissociation.

Primary Structural Dissociation

Primary structural dissociation involves a division into two parts, the apparently normal part (ANP) and the Emotional Part (EP). The ANP handles daily life activities, such as work, social interactions, and routine tasks. The EP holds the traumatic memories and emotions associated with the trauma.

In primary structural dissociation, the ANP and EP can switch control of the person’s behavior and consciousness. The ANP may not be aware of the EP’s existence, which leads to gaps in memory and sense of detachment from certain experiences.

Secondary Structural Dissociation

Secondary structural dissociation involves a more complex division of the personality. In addition to the ANP, there are multiple Eps, where each holds different traumatic memories and emotions. This type of dissociation often occurs in people who have experienced prolonged or repeated trauma.

The ANP in secondary structural dissociation can still handle daily life activities, but the multiple Eps can cause significant disruption. The individual can experience frequent switches between different parts, which leads to confusion, memory gaps, and difficulty in maintaining a consistent sense of self.

Tertiary Structural Dissociation

Tertiary structural dissociation represents the most complex form of dissociation. In involves multiple ANPs and Eps, and each with its own functions and memories. This type of dissociation often occurs in individuals who have experienced severe and chronic trauma, such as childhood abuse or prolonged exposure to violence.

In tertiary structural dissociation, the different parts of the personality can have different identities, preferences, and behaviors. The individual can experience major life disruptions in daily life, including memory loss, identity confusion, and difficulty maintaining relationships.

Treatment and Management of Structural Dissociation

Treatment and management of structural dissociation typically involve a combination of therapy, medication, and self-care strategies. The goal is to help the individual fit in the different parts of their personality and develop a consistent sense of self.

Therapy

Therapy is incredibly important when it comes to treating structural dissociation. Many therapeutic approaches can help persons to understand and manage their symptoms effectively.

For example, trauma-focused therapy is designed to help people process and integrate trauma memories, with the use of techniques like eye movement desensitization and reprocessing (EMDR) and prolonged exposure therapy (PE) to reduce the intensity of these memories and foster healing.

Cognitive behavioral therapy is another valuable approach, as it helps people to identify and change negative or intrusive thought patterns and behaviors. It helps to create a coping strategy to manage emotional instability and improve relationships.

Another method is dialectical behavioral therapy, which is particularly useful for teaching skills in emotional regulation, distress tolerance, and interpersonal effectiveness, which can help people to manage intense emotions and enhance their relationships effectively.

Each of these therapies offers benefits and can be customized to meet the specific needs of people and according to their needs.

Medication

Medication can be a helpful part of managing structural dissociation, even though there is no specific medicine that is designed just for dissociation itself. Certain medicines can ease the related symptoms like anxiety, depression, and emotional ups and downs.

While medicines are not a cure-all, they can be a valuable tool in the overall treatment plan, which helps people feel more balanced and in control.

Structural dissociation provides a framework for understanding how the mind copes with overwhelming experiences. The division of the personality into different parts helps persons to function in their daily routines while it keeps away painful memories at bay. But if it disrupts the daily work of a person, it can be harmful. So, you need to see an experienced psychiatrists who know the situation and can give you a cure according to it.

At Solid Foundation Psychiatry, we have expert practitioners and psychiatrists who can deal with various challenges, treatment, and management strategies that can help you integrate the different parts of your personality and develop a consistent sense of self. With the right support and resources, you can learn to manage symptoms and improve your overall well-being.
