Upstream Counselling offers therapy for dissociative identity disorder, also known as multiple personality disorder. We can help manage this mental health condition impacting identity.

Living with dissociative identity disorder can feel really confusing and exhausting. People with dissociative identity disorder often experience dissociative symptoms, dissociative amnesia, and identity confusion, and it can sometimes feel like their different identities are working against each other. At Upstream Counselling in Kitchener-Waterloo, we help patients with dissociative identity disorder understand their different identities, navigate dissociative phenomena, and start to feel a stronger sense of self again.
In therapy, individuals with dissociative identity disorder learn how to recognize dissociated identity states, communicate between alters, and reduce the fragmentation of identity. Many people notice overlapping symptoms with posttraumatic stress disorder or borderline personality disorder, and working on these together can really help in building a more unified identity.
DID therapy is helpful for anyone diagnosed with dissociative identity disorder or showing symptoms like identity confusion, severe dissociative symptoms, or dissociative amnesia. Our therapists guide patients with dissociative identity disorder in managing symptoms, understanding identity states, and slowly reclaiming a clearer sense of identity—so it’s not just theory, it’s practical support you can actually feel.

At Upstream Counselling, we want you to feel comfortable with the counselling process. Here are some of the most frequently asked questions about talking to a therapist about this type of therapy.
Sometimes it feels like parts of yourself are disconnected, or you can’t quite remember things you should. Recognizing these experiences can be the first step toward understanding and support.
Shifts in personality states: Dissociative identity disorder usually includes different personality states, often called split personality disorder or multiple personality disorder. One identity may or may not be aware of the others.
Memory gaps: Dissociative amnesia can make it hard to recall events, conversations, or even parts of your day. Symptoms cannot simply be explained as normal forgetfulness.
Emotional ups and downs: Symptoms of depression, PTSD symptoms, and other psychological symptoms are often considered symptoms of dissociative disorders. You might notice sudden mood swings or feelings that don’t match what’s happening around you.
Alters with unique traits: Dissociative identity disorder includes alters who might have their own habits, voices, or ways of seeing the world. Symptoms may appear stronger during stressful times or reminders of past trauma.
Physical or sensory changes: Some people notice changes in posture, voice, or handwriting when a different personality state is present.
Triggers and stress: Symptoms depend on emotional stress, trauma reminders, or environmental factors. Dissociative disorders may become more noticeable when life feels overwhelming.
Other dissociative types: Dissociative disorder not otherwise specified (DDNOS) and other major dissociative disorders involve similar symptoms but may not meet the full criteria for DID.
Getting a diagnosis can feel like relief and uncertainty at the same time, but it’s all about understanding your experiences better.
Structured assessments: Diagnosis of dissociative identity disorder using tools like the dissociative experiences scale helps clinicians see patterns of dissociation over time.
Symptom check: Symptoms must include changes in personality states, dissociative amnesia, and other psychological symptoms. Clinicians ensure symptoms cannot be explained by another psychiatric disorder.
Differential diagnosis: Dissociative identity disorder and schizophrenia, factitious disorder, or other identity disorder and dissociative disorder conditions must be ruled out.
History and context: People who develop dissociative disorders often have a history of trauma. The development of dissociative identity disorder usually begins in childhood or adolescence.
Observation of patterns: One identity may or may not appear in certain situations, and symptoms are often mainly dissociative.
Collaboration: Friends or family may provide insight into how dissociative behaviours appear in daily life.
Comprehensive evaluation: Making the diagnosis also includes checking for major dissociative disorders, dissociative disorder not otherwise specified, PTSD symptoms, and symptoms of depression.
Alters are a natural response of your mind to stress or trauma. Understanding them can make the experience feel less confusing.
Alters explained: Dissociative identity disorder includes multiple personality states, sometimes called multiple personality disorder or split personality disorder. Each alter may have its own voice, behaviour, and perspective.
Memory gaps: Dissociative amnesia happens when an alter is in control, and memories from other identities are not accessible. Symptoms may include missing time or forgotten conversations.
Control and awareness: One identity may or may not know about the others, affecting how you behave and remember things.
Triggers: Dissociative disorders may develop as a protective response to trauma. PTSD symptoms or stressful events can trigger an alter to take over.
Behavioural differences: Alters may act, speak, or respond differently depending on which personality state is present. Symptoms depend on stress, context, and life events.
Factitious disorder consideration: While DID is real and not factitious, clinicians sometimes check to ensure symptoms cannot be intentionally produced.
Starting treatment for dissociative identity disorder (DID) can feel overwhelming, but it’s really about learning to live more comfortably with your personality states and managing symptoms in a safe, supportive way. Many people find that just understanding their alters and how they interact is a huge relief.
Symptom-focused care: Dissociative identity disorder treatment helps manage PTSD symptoms, dissociative amnesia, symptoms of depression, and other psychological symptoms. Symptoms must be addressed gradually, because trying to tackle everything at once can feel exhausting. Symptoms of the disorder often depend on stress levels and life events, so therapy adapts to each person’s experience.
Comorbid conditions: DID often overlaps with other psychiatric disorders, such as borderline personality disorder. Treatment considers these conditions too, since the disorder is also frequently interconnected with dissociative symptoms. Therapists create a plan that treats both DID and comorbid conditions, helping people feel more balanced.
Managing alters: Using structured models of dissociative therapy, dissociative identity disorder treatment helps people communicate and cooperate among different personality states. One identity may gradually learn to coexist with others, reducing inner conflict and confusion.
Integration and awareness: Therapy can help reduce memory gaps, improve communication between alters, and support a stronger sense of self, making life feel more stable.
Coping strategies: Grounding, mindfulness, and stress management techniques help people handle triggers and lessen symptoms of the disorder, making daily life more manageable.
Long-term support: Treatment guides people who develop dissociative disorders through the development of dissociative identity disorder, offering ongoing support, understanding, and hope for a more peaceful, connected life.
DID is often misunderstood, but knowing the facts can help you feel validated and less alone.
Debunking myths: Dissociative identity disorder is real, not just split personality disorder or factitious disorder. Symptoms cannot be faked.
Trauma-based development: People who develop dissociative disorders often do so as a response to trauma. The development of dissociative identity disorder is often linked to childhood abuse or repeated stressful events.
Recognizing symptoms: Symptoms include multiple personality states, dissociative amnesia, PTSD symptoms, and symptoms of depression. Symptoms are often mainly dissociative.
Variability: One identity may or may not become dissociative at different times, and symptoms depend on triggers, context, and life experiences.
Scientific perspective: Dissociative disorders may involve overlapping symptoms with other major dissociative disorders. Symptoms must be carefully evaluated using models of dissociative functioning.
Etiology and causes: The etiology of dissociative identity disorder includes trauma, psychological coping mechanisms, and environmental factors. Disorder is also influenced by genetic and social contexts.
Normalizing experiences: Dissociative identity disorder and dissociative disorder conditions are part of the identity disorder in the general population, helping reduce stigma and validate experiences.
