Night Terrors and Nightmares

Night terrors and nightmares are two distinct sleep-related disorders that can cause significant distress and disruption to an individual's sleep patterns.

Definition and Characteristics

• Night Terrors: Also known as sleep terrors, night terrors are a type of sleep disorder that occurs during deep sleep, typically in the first third of the night. They are characterized by intense fear, anxiety, or panic, often accompanied by screaming, thrashing, and flailing.
• Nightmares: Nightmares are vivid, disturbing dreams that occur during the rapid eye movement (REM) stage of sleep, typically in the latter half of the night. They can be highly distressing and may cause the individual to wake up feeling anxious or frightened.

Causes and Risk Factors

• Genetics: Family history can play a role in the development of night terrors and nightmares.
• Sleep Deprivation: Lack of sleep or disrupted sleep patterns can increase the risk of experiencing night terrors and nightmares.
• Stress and Anxiety: High levels of stress and anxiety can contribute to the development of night terrors and nightmares.
• Certain Medications: Certain medications, such as sedatives and antidepressants, can increase the risk of experiencing night terrors and nightmares.
• Underlying Medical Conditions: Certain medical conditions, such as sleep apnea, restless leg syndrome, and gastroesophageal reflux disease (GERD), can increase the risk of experiencing night terrors and nightmares.
