Multiple Personality Disorder (MPD), now known as Dissociative Identity Disorder (DID)

Multiple Personality Disorder, also referred to as Dissociative Identity Disorder (DID), is a complex mental health condition characterized by the presence of two or more distinct identities or personality states within an individual. These alternate personalities, often referred to as "alters," may have their own thoughts, feelings, and behaviors that are different from those normally associated with the person.

Key Features:

• Presence of two or more distinct identities or personality states
• Alternation between these identities, which may be accompanied by memory gaps or amnesia
• Each identity may have its own speech, temperamental, and behavioral patterns
• Often developed as a result of severe trauma, abuse, or stress during early childhood

Symptoms:

• Memory lapses or gaps in recollection
• Difficulty recalling specific events or experiences
• Feeling disconnected from one's thoughts, feelings, or actions
• Presence of multiple identities or personalities within an individual

Causes and Risk Factors:

• Severe trauma, abuse, or stress during early childhood (typically before the age of 5-6)
• History of neglect, abandonment, or emotional abuse
• Presence of other mental health conditions, such as depression or anxiety disorders

Prevalence:

• Approximately 1.5% of the population internationally has been diagnosed with dissociative identity disorder [11]
• More common among individuals who have experienced severe trauma or abuse during childhood

[1] - According to the DSM-5-TR, early childhood trauma places someone at risk of developing dissociative identity disorder (DID) [6]

[2] - Dissociative identity disorder is associated with overwhelming experiences, traumatic events, and/or abuse that occurred in childhood [7]

[3] - DID is defined by the presence of two or more distinct identities or personality states that recurrently take control of behavior [8]

[4] - People with dissociative identity disorder often experience amnesia, which means they don't remember what happens when another part of their identity is in control [15]

Dissociative Identity Disorder (DID) Signs and Symptoms

Dissociative Identity Disorder, previously known as Multiple Personality Disorder, is a complex mental health condition characterized by the presence of two or more distinct identities or personalities within an individual. The signs and symptoms of DID can vary from person to person but often include:

• Change between two or more separate personalities: This is one of the most common symptoms of DID, where individuals may experience sudden changes in behavior, mood, or thoughts, indicating a shift between different personalities.
• Anxiety: Individuals with DID often experience anxiety, which can manifest as feelings of fear, worry, or unease.
• Depression: Depression is another common symptom of DID, characterized by persistent feelings of sadness, hopelessness, and loss of interest in activities.
• Self-harm: Some individuals with DID may engage in self-destructive behaviors, such as cutting or burning themselves, as a way to cope with their emotions.
• Substance use disorder: People with DID may also struggle with substance abuse or addiction as a means to escape their emotional pain.
• Thoughts about suicide: Unfortunately, some individuals with DID may experience suicidal thoughts or feelings of wanting to harm themselves.

Other symptoms

In addition to the above-mentioned symptoms, people with DID may also experience:

• Memory loss: Individuals with DID often have difficulty recalling specific events, times, or details.
• Dissociation: This can manifest as feeling detached from one's body or surroundings.
• Out-of-body experiences: Some individuals with DID may report experiencing out-of-body sensations, where they feel as if they are observing themselves from outside their physical body.

Diagnostic Tests for Dissociative Identity Disorder (DID)

Dissociative identity disorder, formerly known as multiple personality disorder, is a complex mental health condition that involves experiencing shifts between at least two separate identities or personalities. While there isn't a single test that can diagnose DID, various diagnostic tools and assessments are used to help identify the condition.

• Psychological testing: Some measures commonly used in psychological testing, such as the Rorschach Inkblot Test, Minnesota Multiphasic Personality Inventory–2, and Wechsler Adult Intelligence Scale, may be used to assess symptoms of dissociative identity disorder [9].
• Diagnostic criteria: The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) provides diagnostic criteria for dissociative identity disorder, which includes experiencing shifts between two or more distinct identities or personality states within a single individual [12].
• Self-assessment tests: Some online resources offer self-assessment tests, such as the one provided by The Recovery Village, to help individuals determine whether they might have symptoms of DID [12]. However, these tests should not be relied upon for an official diagnosis.
• Clinical evaluation: A comprehensive clinical evaluation, including a physical examination and laboratory tests, may be necessary to rule out other conditions that may be causing the symptoms [6].

It's essential to note that only a qualified mental health professional can accurately diagnose dissociative identity disorder. If you're concerned about your symptoms or those of someone else, it's crucial to consult with a qualified healthcare provider for an official diagnosis and proper treatment.

Medication as a Part of Treatment

While therapy remains the most effective treatment for dissociative identity disorder (DID), medication can also play a role in managing symptoms and co-occurring conditions.

• Selective Serotonin Reuptake Inhibitors (SSRIs): Some studies have reported success with SSRIs, such as fluoxetine (Prozac) and sertraline (Zoloft), in reducing symptoms of depression and anxiety in individuals with DID [3].
• Tricyclic Antidepressants: Tricyclic antidepressants, like amitriptyline (Elavil), have also been used to treat co-occurring depression and anxiety disorders in individuals with DID [3].
• Monoamine Oxidase Inhibitors (MAOIs): MAOIs, such as phenelzine (Nardil), may be effective in treating symptoms of depression and anxiety in individuals with DID, although their use is generally limited due to potential side effects [3].

Important Considerations

• Medication should not be used as a replacement for therapy but rather as an adjunctive treatment to help manage symptoms.
• The effectiveness of medication can vary depending on the individual and the specific symptoms being treated.
• Co-occurring conditions, such as depression or anxiety disorders, may require separate treatment plans.

The differential diagnosis for multiple personality disorder, now commonly referred to as dissociative identity disorder (DID), involves ruling out other mental health conditions that may present with similar symptoms.

According to the diagnostic criteria outlined in the DSM-5 [5], the following conditions should be considered in the differential diagnosis of DID:

• Other specified dissociative disorder: This condition is characterized by symptoms of dissociation, such as depersonalization or derealization, but does not meet the full criteria for DID.
• Major depressive disorder: Patients with major depression may exhibit symptoms of dissociation, such as feeling disconnected from their emotions or surroundings.
• Bipolar disorders: Individuals with bipolar disorder may experience episodes of dissociation, particularly during manic or depressive episodes.
• Posttraumatic stress disorder (PTSD): PTSD can involve symptoms of dissociation, especially in individuals who have experienced trauma.

It's also worth noting that some researchers have suggested a possible link between DID and borderline personality disorder (BPD) [9]. However, the relationship between these two conditions is still a topic of debate among experts.

In terms of diagnostic criteria, the DSM-5 specifies that two or more distinct identities or personality states must be present in order to diagnose DID [5]. Additionally, the symptoms of dissociation must cause significant distress or impairment in social, occupational, or other areas of functioning.

It's essential for mental health professionals to carefully evaluate patients with suspected DID and consider these differential diagnoses when making a diagnosis.
