Insights

Preterm toddlers experience more nighttime awakenings and daytime activity compared to their term-born peers. This suggests unique sleep development patterns in children born preterm.

Area of Science:

  • Pediatric Sleep Medicine
  • Developmental Pediatrics
  • Neonatal Follow-up

Background:

  • Sleep problems are common in children born preterm.
  • Previous studies on preterm children's sleep show varied results due to different methodologies.
  • Reliable data on sleep characteristics in this population is needed.

Purpose of the Study:

  • To investigate differences in sleep properties between preterm and term toddlers.
  • To obtain reliable sleep data using objective actigraphy.

Main Methods:

  • Actigraphy was used to monitor sleep for 7 consecutive days in 97 preterm and 97 term toddlers (approx. 1.5 years old).
  • Parents also completed a child sleep diary.
  • Objective actigraphy provided detailed sleep metrics.

Main Results:

  • Preterm toddlers exhibited significantly more nocturnal awakenings.
  • Preterm toddlers demonstrated increased daytime activity levels.
  • Objective actigraphy revealed distinct sleep patterns.

Conclusions:

  • Preterm-born children may undergo a different sleep development trajectory.
  • Findings highlight potential sleep regulation differences in early development.
  • Actigraphy offers a reliable method for assessing pediatric sleep.

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Narcolepsy01:07

Narcolepsy

Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
