Narcolepsy01:07

Narcolepsy

348
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.

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

2.5K
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:

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

992
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...

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

305
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.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

599
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Management of Insomnia01:19

Management of Insomnia

423
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Area of Science:

  • Neurology
  • Pediatrics
  • Sleep Medicine

Background:

  • Secondary narcolepsy results from hypothalamic lesions affecting wakefulness.
  • Data on pediatric secondary narcolepsy is limited compared to adults.

Purpose of the Study:

  • To retrospectively review the characteristics and outcomes of secondary narcolepsy in children.
  • To understand the variability and etiology-specific course of this condition in pediatric patients.

Main Methods:

  • Retrospective review of medical records for 10 pediatric patients diagnosed with secondary narcolepsy at Mayo Clinic.
  • Extraction of data on underlying neurological disorders, narcolepsy subtype, sleep studies, treatments, and outcomes.

Main Results:

  • Diagnosis age ranged from 6 to 17 years, with 50% experiencing excessive sleepiness within one year of the primary disorder.
  • 60% had narcolepsy type 1 (with cataplexy), 40% had type 2 (without cataplexy).
  • 80% required ongoing treatment for sleepiness 6.6 years post-diagnosis; one patient died, and one showed spontaneous remission.

Conclusions:

  • Secondary narcolepsy is a significant chronic condition following childhood brain lesions with diverse, etiology-dependent outcomes.
  • This study highlights the variable clinical course and the rare possibility of spontaneous symptom resolution in pediatric secondary narcolepsy.
