REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

470
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

235
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.
Understanding the concepts of physical dependence,...

Sleepwalking and Sleep Talking

351
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

Narcolepsy01:07

Narcolepsy

218
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.

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

175
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.

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

1.8K
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:

Area of Science:

  • Neurology
  • Sleep Medicine
  • Pediatrics

Background:

  • Healthy sleep is crucial for growth, development, and health.
  • Tourette Disorder (TD) is frequently associated with Attention Deficit Hyperactivity Disorder (ADHD), exacerbating sleep problems.
  • Sleep disturbances are a common and significant issue in individuals with TD.

Purpose of the Study:

  • To review the impact of Tourette Disorder on sleep patterns.
  • To identify common sleep abnormalities associated with TD.
  • To discuss the relationship between TD, ADHD, and sleep.

Main Methods:

  • Review of polysomnography studies in patients with TD.
  • Analysis of sleep onset and maintenance insomnia incidence.
  • Examination of potential links to parasomnias and hypersomnolence.

Main Results:

  • Patients with TD exhibit decreased total sleep time, lower sleep efficiency, and elevated arousal index.
  • Tics and movements persist during both REM and NREM sleep in TD patients.
  • Increased incidence of insomnia and potential parasomnias are noted, with hypersomnolence possibly secondary to sleep disruption.

Conclusions:

  • Sleep disturbances are a prominent feature of Tourette Disorder.
  • Addressing underlying TD is essential for managing sleep-related manifestations.
  • While not significantly linked to sleep-disordered breathing or circadian issues, TD profoundly impacts sleep architecture and quality.
