Problem 2 - Abnormal Psychology: An Integrative Approach

Question

Diagnose the sleep problems of the cases here using one of the following: (a) nocturnal eating syndrome, (b) sleep terrors, and (c) nightmares. Sho-jen’s parents hear her piercing screams on many nights and rush to comfort her, but she does not respond. During these episodes, her heart rate is elevated, and her pajamas are soaked in sweat. When she gets up the next day, however, she has no memory of the experience. ______________

Step-by-Step Solution

Answer

Sho-jen's sleep problem is sleep terrors.

Step 1: Identify Key Symptoms

Sho-jen experiences piercing screams during the night, has an elevated heart rate, sweats excessively, and lacks memory of the episodes upon waking. These are critical symptoms to note.

Step 2: Analyze Symptoms for Diagnosis

Compare the identified symptoms with the characteristics of the three disorders: (a) nocturnal eating syndrome involves waking and eating, (b) sleep terrors involve screaming, sweating, increased heart rate, and no recall of the episode, (c) nightmares involve detailed recall upon waking. Sho-jen's symptoms align most closely with descriptions of sleep terrors.

Step 3: Match Symptoms to Diagnostic Criteria

For sleep terrors, the diagnostic criteria include loud screams, intense fear, autonomic arousal (such as an increased heart rate), and amnesia for the event. Sho-jen's symptoms match these criteria, confirming that her condition is sleep terrors.

Key Concepts

Nocturnal Eating Syndrome

Nocturnal Eating Syndrome (NES) is a disorder where individuals consume food during the night, often waking from sleep to do so. It is different from sleepwalking as those with NES are fully aware of their actions while eating. They may not wake entirely but may be semi-conscious during the eating episodes. This syndrome can lead to nutritional issues, sleep disruption, and even weight gain over time.

• People with NES often feel they need to eat to initiate or return to sleep at night.
• Unlike other sleep disorders, these eating episodes are paired with insomnia or difficulty in maintaining a restful state.
• NES can contribute to both physical and psychological distress, exacerbating mood disorders such as depression or anxiety.

Understanding NES is critical for appropriate diagnosis and management, as it requires distinguishing between physical hunger and habitual behavior associated with sleep disturbances.

Sleep Terrors

Sleep terrors, or "night terrors," are intense episodes of fear during sleep, often accompanied by screaming, thrashing, and a heightened autonomous response. They usually occur in the first third of the night during non-REM sleep, differentiating them from nightmares which occur during REM sleep.

• Typical symptoms include the following:
  • Loud screams causing awakenings.
  • Increased heart rate and sweating.
  • No recall of the event upon waking.
• Sleep terrors are more common in children, often resolving with adolescence.
• The individual experiencing a terror may seem awake, but they are actually not fully conscious and may not respond coherently.

Establishing this as a diagnosis can help family members know what to expect and how best to support someone experiencing these episodes.

Nightmares

Nightmares are unsettling dreams that cause strong feelings of fear, terror, distress, or anxiety. Typically, these vivid dreams occur during REM sleep, a phase of sleep characterized by rapid eye movements and increased brain activity.

• Nightmares are unique in sleep disorders because:
  • Individuals remember them clearly upon waking.
  • They can lead to difficulty falling back asleep or feelings of fear.
• Occasional nightmares are normal; however, frequent occurrences may indicate psychological concerns such as stress or trauma.
• Children may experience them more frequently, but they often decrease with age.

Managing nightmares often involves psychological strategies such as dream rehearsal therapy or addressing underlying stressors.

Symptoms Analysis

Analyzing symptoms is the cornerstone of diagnosing sleep disorders. It involves observing physical, emotional, and behavioral cues during episodes of disrupted sleep. Recognizing patterns in these symptoms allows healthcare professionals to match them with possible disorders.

• Sleep disorders symptoms often include:
  • Erratic sleep patterns or disturbances.
  • Physical signs like sweating or increased heart rate.
  • Behavioral manifestations such as screaming or thrashing.
• Memory of these events plays a crucial diagnostic role.
  • Amnesia suggests a non-REM disorder such as sleep terrors.
  • Detailed recall often points to conditions like nightmares.

Effective symptom analysis guides appropriate intervention strategies and provides a basis for exploring contributing factors.

Diagnostic Criteria

Diagnostic criteria are standardized signs and symptoms used to identify sleep disorders. These criteria provide a framework for healthcare providers to ensure accurate diagnosis and treatment.

• Key diagnostic elements for sleep disorders include:
  • Specific physiological responses during episodes (e.g., autonomic arousal during sleep terrors).
  • Behavioral and psychological conditions related to sleep phases.
  • History of symptoms and any patterns or triggers associated with their occurrence.
• Matching symptoms with established criteria allows for precise identification of the sleep disorder type.
• Diagnostic tools may include sleep studies, patient interviews, and questionnaires.

By adhering to these criteria, medical professionals can differentiate between disorders, ensuring a tailored and effective approach to sleep health management.
