Diagnostic Criteria for Nightmare Disorder

According to the International Classification of Sleep Disorders (ICSD-3) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the diagnostic criteria for Nightmare Disorder are:

1. Recurrent nightmares: Frequent occurrences of nightmares, defined as vivid, disturbing dreams that typically occur during REM sleep.

2. Distress and impairment: Nightmares cause significant distress, anxiety, or fear, and impair daily functioning, social relationships, or work performance.

3. Frequency and duration: Nightmares occur at least once a week for at least one month.

4. Content: Nightmares typically involve threat, danger, or horror themes.

5. Wake-up and recall: The individual wakes up from the nightmare and recalls the content.

6. Sleep quality: Nightmares disrupt sleep quality, leading to insomnia, daytime fatigue, or other sleep-related problems.

7. Exclusion criteria: Nightmares are not better explained by another sleep disorder, mental health condition, or medication/substance use.

Additional criteria

• Nightmares may be accompanied by sleep paralysis, sleep talking, or other sleep-related behaviors.
• Individuals may exhibit avoidance behaviors, such as avoiding sleep or using substances to reduce nightmares.
• Nightmare Disorder can co-occur with other mental health conditions, such as post-traumatic stress disorder (PTSD), depression, or anxiety disorders.

Signs and Symptoms

Signs and Symptoms of Nightmare Disorder (Dream Anxiety Disorder):

Common Symptoms

1. Recurring Nightmares: Frequent, vivid, and disturbing dreams that evoke strong emotions like fear, anxiety, or horror.

Differential Diagnosis

Differential Diagnosis of Nightmare Disorder (Dream Anxiety Disorder) involves considering other conditions that may present with similar symptoms, such as:

1. Sleep Terrors (Sleep Arousal Disorder): Characterized by sudden awakenings with intense fear, screaming, and thrashing. Unlike nightmares, sleep terrors occur during non-REM sleep and are often not remembered.

2. Post-Traumatic Stress Disorder (PTSD): Nightmares are a common symptom of PTSD, but the disorder also includes other symptoms like flashbacks, avoidance, and hyperarousal.

3. Anxiety Disorders: Generalized anxiety, panic disorder, and social anxiety disorder can all present with nightmares, but are distinguished by their characteristic anxiety symptoms.

4. Mood Disorders: Major depressive disorder and bipolar disorder can include nightmares, but are primarily characterized by mood symptoms.

5. Sleep-Related Eating Disorder: Characterized by eating during sleep, often accompanied by nightmares.

6. REM Sleep Behavior Disorder: Characterized by acting out dreams during REM sleep, often with nightmares.

7. Substance-Related Disorders: Substance use or withdrawal can trigger nightmares.

8. Sleep Apnea: Pauses in breathing during sleep can lead to nightmares.

9. Nocturnal Panic Attacks: Panic attacks that occur during sleep, often with nightmares.

10. Nighttime Waking due to Medical Conditions: Pain, sleep apnea, or other medical conditions can cause nighttime waking, which may be mistaken for nightmares.

To accurately diagnose Nightmare Disorder, consider the following:

• Detailed sleep history
• Mental status examination
• Comorbid conditions
• Timing and content of nightmares
• Daytime symptoms
• Sleep stage (REM or non-REM)
