REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

1.3K
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...

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

2.7K
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:

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

391
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,...

Narcolepsy01:07

Narcolepsy

475
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

437
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.

Lucid Dreaming01:10

Lucid Dreaming

495
Lucid dreaming is a unique state of consciousness where an individual realizes they are dreaming while still in the dream. This awareness allows them to manipulate their dream environment consciously. Researchers like Stephen LaBerge have significantly contributed to the understanding of lucid dreams, highlighting that during these dreams, certain areas of the brain, such as the prefrontal cortex, that involve self-awareness and thought evaluation show increased activity.
Studies have shown...

Area of Science:

  • Neurology
  • Sleep Medicine
  • Psychiatry

Background:

  • Functional Neurological Disorder (FND) is a condition affecting brain function, leading to neurological symptoms.
  • Sleep disturbances are anecdotally reported in FND but require further investigation.

Purpose of the Study:

  • To explore sleep disturbance in functional neurological disorder (FND).
  • To investigate the impact of sleep disturbance on FND symptoms.

Main Methods:

  • An online questionnaire was developed with FND charities.
  • 373 adults with self-reported FND participated.

Main Results:

  • 86% of participants were women; 73% reported poor sleep quality.
  • 93% reported nonpositive dream content, 78% had weekly nightmares.
  • 46% noted symptom improvement after good sleep; 88% reported symptom worsening related to sleep.
  • 74% of those with functional seizures reported they occurred during sleep.

Conclusions:

  • Findings confirm poor sleep quality, nightmares, and negative dreams in FND.
  • Self-reported sleep and dream content may influence FND symptoms.
  • High risk for selection and recall bias acknowledged.
