A 3-year-old awakened from deep sleep showed confusion and disorientation. Which statement best describes this pattern?

• A. This is a sign of nightmares.
• B. This is probably benign, temporary sleep disorder.
• C. This is a sign of sleep walking.
• D. This is a type of sleep terror which will resolve over time.

Answer: (B)

The key idea is recognizing a common, benign sleep phenomenon in young children: confusional arousals from deep sleep. When a preschooler is awakened during the deepest stage of non-REM sleep, they may appear confused, disoriented, and slow to respond, with little or no memory of the event afterward. This pattern is typically brief and self-limited, and it often improves with age or by improving sleep hygiene (regular bedtimes, adequate sleep, avoiding sleep deprivation). This differs from nightmares, which occur during REM sleep later at night and involve vivid dreams with distress and recall upon waking. It also differs from sleepwalking or sleep terrors (arousal disorders), which involve more dramatic behaviors during sleep and either partial or complete inability to be easily comforted, with different patterns of timing and memory.
