Problem 1 - Abnormal Psychology: An Integrative Approach

Question

Diagnose the dissociative disorders described here by choosing one of the following: (a) dissociative fugue, (b) depersonalization-derealization disorder, (c) generalized amnesia, (d) dissociative identity disorder, and (e) localized amnesia. Ann was found wandering the streets, unable to recall any important personal information. After searching her purse and finding an address, doctors were able to contact her mother. They learned that Ann had just been in a terrible accident and was the only survivor. Ann could not remember her mother or any details of the accident. She was distressed. ______________

Step-by-Step Solution

Answer

Ann is likely experiencing dissociative fugue.

Step 1: Identify Key Symptoms

Begin by reading the provided case scenario and identifying key symptoms and facts associated with the individual's behavior. In this scenario, Ann is found wandering without knowing her personal information and is unable to remember her mother or details of the recent accident.

Step 2: Analyze Dissociative Disorder Options

Examine the characteristics of the different dissociative disorders: - (a) Dissociative fugue involves sudden, unexpected travel away from home and an inability to recall one's past, often coupled with confusion about personal identity. - (b) Depersonalization-derealization disorder is marked by feelings of detachment from the self or reality. - (c) Generalized amnesia is a type of dissociative amnesia where the person forgets their entire history and identity. - (d) Dissociative identity disorder is characterized by the presence of two or more distinct personality states. - (e) Localized amnesia involves forgetting events from a specific period.

Step 3: Match Symptoms to Disorders

Let's match Ann's symptoms with the disorders: - Ann is unable to recall personal information (general knowledge), which doesn't fit localized amnesia, as localized amnesia involves forgetting events of a particular time. - Ann does not display multiple personalities, ruling out dissociative identity disorder. - She is wandering and unable to remember her identity, matching with dissociative fugue characteristics.

Step 4: Confirm Diagnosis

The primary symptoms of wandering, inability to recall personal information, and disorientation align well with dissociative fugue. The fact that this behavior followed a traumatic event (the accident) strengthens this diagnosis since dissociative fugue often occurs after trauma.

Key Concepts

Dissociative Fugue

A dissociative fugue is a rare but intriguing condition. It involves sudden and unexpected travel away from familiar environments which is accompanied by an inability to recall one’s past. Individuals in a fugue state may forget personal information, such as their name, address, or family members. This can result in total disorientation and confusion.

Key characteristics of dissociative fugue include:

• Sudden departure from home or work
• Inability to recall past events or personal information
• Confusion about personal identity or assumption of a new identity
• Occurrence often linked to traumatic events or stress

To illustrate, consider someone like Ann, described in our scenario. After surviving a traumatic accident, she was found wandering and confused, unable to recall crucial details about herself or her life. This onset after trauma is typical in such cases, making dissociative fugue a fitting diagnosis. It highlights the powerful effect traumatic experiences can have on an individual's mental state.

Generalized Amnesia

Generalized amnesia is another type of dissociative disorder characterized by an extensive loss of memory. Unlike localized amnesia, which involves forgetting events during a specific time period, generalized amnesia affects broad swathes of memory. This can include one’s complete life history and personal identity.

The symptoms of generalized amnesia can be particularly distressing for both the individual and their loved ones, as it may render them unable to remember who they are or recognize their family, home, or work.

Key features of generalized amnesia include:

• Inability to recall any aspect of one’s life history
• Loss of personal identity
• Can persist for a variable duration, often showing no structural brain damage detectable by imaging techniques
• Usually triggered by significant stress or trauma

Though Ann showed some symptoms that might initially suggest generalized amnesia, such as her inability to remember personal details, the wandering and identity confusion align more directly with dissociative fugue. The distinction is subtle but significant in terms of diagnosis and understanding.

Dissociative Identity Disorder

Dissociative Identity Disorder (DID), formerly known as multiple personality disorder, is characterized by the presence of two or more distinct and alternating personalities in a single individual. Each identity can have its own name, age, gender, history, and pattern of behaviors or preferences. This disorder is often a response to severe trauma during early childhood.

Key aspects of DID include:

• Presence of two or more distinct personalities
• Memory gaps regarding everyday events or personal information
• Significant distress or impairment in social and occupational areas of life
• Symptoms are not a part of the normal cultural or religious practices

Importantly, Ann does not display any of these symptoms, such as shifting between personalities or experiencing memory gaps related to more states than just the trauma-centric ones. This is why dissociative identity disorder was ruled out in our analysis of her condition. Understanding DID requires comprehension of its complex structure and triggers, distinguishing it from other dissociative disorders like the fugue state.
