Living with Dissociative Identity Disorder: What Young Adults and Families Should Know

Young adulthood is already one of the most demanding transitions in a person’s life — a time of building independence, navigating relationships, and figuring out who you are. For young adults living with Dissociative Identity Disorder (DID), that process is far more complicated. Many describe feeling like they are watching their own life from the outside, detached from reality, their emotions, and their sense of self. This disconnection can make everyday tasks exhausting and relationships difficult to maintain. 

Despite how significantly it can affect a young person’s life, DID remains one of the most misunderstood mental health conditions. Much of this confusion stems from media portrayals that depict DID as dramatic and frightening with obvious switches between alters (alternate identity states). The reality, however, looks very different from what we see in movies or TV shows.

To better understand what Dissociative Identity Disorder actually looks like beyond the misconceptions, we sat down with Cristina Escobar, LCSW, Clinical Supervisor at The Dorm NYC to discuss the reality of the condition, the stigma surrounding it, and what treatment and long-term recovery looks like for young adults working toward functional, fulfilling lives.

How does Dissociative Identity Disorder present in young adults?

Cristina Escobar, LCSW: Dissociative Identity Disorder (DID) can present differently from person to person. It typically develops as a protective response to trauma, where a person’s identity fragments into distinct parts called “alters.” Alters are distinct psychological states with DID that each carry their own relatively stable patterns of perception, emotion, memory, behavior, and sense of self.  Different alters may emerge depending on the situation and what’s needed to cope in that moment.

The media often sensationalizes DID by depicting dramatic and obvious personality switches. In reality, transitions between alters are usually much more subtle: small changes in tone of voice, body language, clothing choices, or mannerisms that differ from what you typically expect from them. 

Some people with DID experience amnesia during shifts between alters, meaning they lose awareness of what happened while a different part was present. They would remember leaving for the store in the morning but suddenly find themselves back in their apartment in the evening with no recollection of what happened in between. During that missing time, a different part of their identity had been present. 

Friends and family may notice other distinct shifts in:

• Preferences
• Speech patterns
• Personality traits 

Young adults with DID may also discover evidence of these different parts in their own life. One client I had recalled finding their journal entries written in completely different handwriting and writing styles. This served as proof that an alter was present during a time they couldn’t remember.

Why is DID so commonly misunderstood?

Dissociative Identity Disorder is often misunderstood partly because the terminology around the disorder has evolved. Many people still know it by its former name, Multiple Personality Disorder. 

DID is also relatively uncommon compared to other mental health conditions; research suggests that approximately 1-1.5% of the general population has DID and often goes undiagnosed. This rarity contributes to widespread misunderstanding about the disorder, and means that young adults can go years without an accurate diagnosis or appropriate treatment.

Much of what people know about DID comes from media portrayals that depict it as violent and frightening. In the movie Split, for example, the main character switches into dangerous and vicious alters. These depictions shape public perception about the disorder in harmful ways, reinforcing the idea that people with DID are unpredictable or dangerous.

In my experience working with young adults who have DID, I’ve noticed they have profound feelings of shame around their diagnosis. Sharing their experiences is particularly difficult due to the stigma surrounding the condition and the fear of being misunderstood or judged by others. 

How does DID develop, and how does it affect everyday life?

DID typically develops in response to extreme trauma. When reality becomes too overwhelming or frightening to process, the mind fragments as a protective mechanism, creating separate identities to protect itself from reality. 

Since DID stems from trauma, young adults with this condition experience a range of trauma-related symptoms including:

• Hypervigilance
• Anxiety
• Nightmares
• Dissociation

Young adults diagnosed with DID will describe feeling constantly disconnected from their own lives. They report tiredness, heaviness, and a sense of being “out of body”. For young adults, this disconnection is especially disorienting when different alters manage different aspects of life. For example, if one alter handles friendships while another focuses on academics, the person may never feel fully present or connected to any part of their own experience. That fragmentation makes an already demanding stage of life even harder, complicating the work of building a stable identity while navigating school, careers, and relationships all at once.

In addition, individuals also have significant gaps in their own memory and understanding. For instance, in educational settings, memory gaps and dissociative episodes can make it difficult to retain information, attend classes consistently, or follow through on assignments. In intimate relationships, amnesia can cause the young adult to forget important conversations or shared experiences, which can be confusing and hurtful to partners and friends.  

If DID goes untreated, there is also the risk of being more vulnerable to re-traumatization. Without understanding why they lost time, act in ways they don’t remember or feel like different people in different contexts, they are more likely to engage in risky behavior or be exploited. Each new trauma can deepen and complicate the existing structure of the disorder. 

What do clinicians look for when diagnosing DID? 

In diagnosing DID, five criteria must be present:

• Two or more distinct personality states (alters) may be experienced by the patient
• Amnesia or recurring gaps in memory for everyday events
• Clinically significant distress or impairment in social, occupational, or other important areas
• Not attributable to substance use (e.g. blackouts from alcohol, seizure from medical condition)
• Not better explained by imaginary play in children, or by cultural/religious practices

Beyond the formal criteria, there are behavioral and experiential cues that can signal DID during clinical assessment such as referring to oneself in the third person, unexplained gaps in time, and inconsistent presentation across sessions. A significant childhood trauma history is also a common thread, though patients may not disclose it readily or may not have conscious access to it.

What makes the treatment journey for DID challenging?

One of the challenges in treating DID is that different alters may appear across therapy sessions. 

A person with DID can have many different alters, each with distinct characteristics, preferences, and memories. Working through this in therapy is like assembling a complex puzzle where pieces are missing or unclear due to the young adult’s gaps in memory and understanding. While alters serve a “protective function,” they don’t always use healthy or adaptive coping strategies. 

I had a client whose alter engaged in self-harm. This was a very scary experience for them because they would wake up with cuts or scars they didn’t recall inflicting. Therapy became challenging because my client who I typically worked with was motivated and receptive, actively learning and practicing coping skills that we discussed. However, when their alter appeared in sessions, they were resistant to treatment and unwilling to engage with therapeutic strategies. So I wasn’t just working with one person, I was working with multiple parts of the same person.

This is why working with the entire system is so important in treating DID. The goal isn’t to treat alters as separate personalities, but to recognize them as parts of the same person. This reduces internal conflict, builds communication between parts, and improves overall functioning. We can’t successfully treat one alter in isolation; we need to engage with the whole system.

The most effective treatment works toward helping the different parts learn to coexist and function cooperatively as a system, and integrating these parts so the individual can function more fully in life. 

What are the treatment modalities used in DID treatment?

Phase-based treatment is the clinical gold standard treatment for DID. Rather than jumping straight into trauma processing, treatment is sequenced deliberately across three phases:

• First phase: Establishing safety, stabilization, and symptom reduction.
• Second phase: Processing underlying traumatic material.
• Third phase:  Working toward integration and rehabilitation in daily life. 

This structure is important because processing trauma before a client is stable can be retraumatizing rather than healing. 

Psychoeducation is key across all phases. Learning about the diagnosis can be validating for young adults, especially since DID is relatively rare and often feels isolating due to stigma. Understanding that others share similar experiences helps with connection and reduces feelings of loneliness.

Within this framework, there are several therapeutic approaches that support treatment:

• Internal Family Systems (IFS), or parts work, helps clients identify, understand, and communicate with their different parts. The therapist works with the client to acknowledge each part’s role and purpose, with the goal of reducing internal conflict and fostering cooperation and harmony between parts.

• Trauma-Focused Therapy (psychodynamic trauma work) can be effective depending on the individual. When a client has some awareness of their traumatic experiences, it creates an opportunity for processing the underlying trauma while also working to improve communication and cooperation between identity states.

• EMDR (Eye Movement Desensitization and Reprocessing) uses guided eye movements to help clients reprocess distressing memories so they feel less overwhelming. EMDR protocols are modified for DID to account for the fragmented nature of traumatic memory across parts.

What does long-term recovery look like for young adults with DID?

The goal of treatment is to reduce internal conflict and improve quality of life, whether that means working toward greater integration of identity states or helping the different parts learn to coexist and function cooperatively as a system.

Someone with DID may not be aware of all of their alters, and alters may not be aware of each other. The therapist’s role is twofold: to get to know each alter individually, and to help the client build a relationship with their alters. This includes understanding each alter’s role and purpose, their personal narrative, and especially in trauma work, what that alter has experienced and carried.

During treatment, individuals also learn skills to manage anxiety and trauma triggers. As they learn to manage their symptoms, dissociative episodes become less frequent because it reduces the need to switch alters as a protective mechanism. 

Progress looks different for each person. For some, it may involve alters gradually integrating over time. For others, progress looks like improved communication between parts, reduced internal conflict, and greater stability in daily functioning. The goal is to help young adults feel more present and connected to daily life. 

With the right treatment and support, young adults with DID can go on to live stable, fulfilling, and meaningful lives. Receiving a diagnosis is the first step to understanding and healing. For young adults, earlier intervention means they have more time to build coping skills, engage in therapy, and establish a strong foundation to better handle the full weight of adult responsibilities going forward.
