Stress and anxiety: Emotional stress can trigger episodes
Fever and illness: Physical illness can precipitate night terrors

Sleep-Related Factors

Irregular sleep schedule: Disruption of normal sleep patterns
Sleep environment changes: Unfamiliar surroundings can trigger episodes
Sleep fragmentation: Frequent arousals during sleep
Deep sleep disturbances: Arousals from stage 3-4 NREM sleep

Developmental Factors

Brain development: Immature central nervous system in children
Sleep cycle maturation: Development of normal sleep architecture
Hormonal changes: Puberty and other hormonal transitions
Stress sensitivity: Children may be more sensitive to stress

Medical and Neurological Factors

Sleep apnea: Breathing disturbances can trigger arousals
Restless leg syndrome: Sleep fragmentation increases risk
Migraine headaches: Associated with sleep disturbances
Seizure disorders: Sometimes mistaken for night terrors

Medication and Substance Factors

Medications: Certain medications can affect sleep architecture
Alcohol: Disrupts sleep patterns and can trigger episodes
Caffeine: Stimulates nervous system affecting sleep quality
Withdrawal effects: Coming off medications or substances

Night Terrors vs. Nightmares

Key Differences

Timing

Night terrors: Occur in first third of night during deep sleep
Nightmares: Occur in second half of night during REM sleep

Response to Waking

Night terrors: Difficult to wake, may become more agitated
Nightmares: Can be awakened and comforted

Memory and Recall

Night terrors: No memory of the episode
Nightmares: Often remembered in detail upon waking

Physical Activity

Night terrors: Often involve sitting up, thrashing, or getting out of bed
Nightmares: Usually minimal physical movement
