Insights

Early recognition of narcolepsy in children is crucial. This case highlights narcolepsy with cataplexy in a three-year-old, emphasizing the importance of polysomnography and MSLT for diagnosis.

Area of Science:

  • Neurology
  • Sleep Medicine

Background:

  • Narcolepsy, a chronic neurological disorder, presents with excessive daytime sleepiness, sleep paralysis, hallucinations, and cataplexy.
  • Early diagnosis in pediatric cases is vital for proper growth and development.

Observation:

  • A three-year-old girl exhibited symptoms suggestive of narcolepsy.
  • Diagnostic evaluations included brain MRI, 24-hour video-EEG, polysomnography (PSG) with multiple sleep latency test (MSLT), and HLA DQ typing.

Findings:

  • Brain MRI results were normal.
  • 24-hour video-EEG showed no epileptiform discharges and no changes during cataplexy events.
  • PSG with MSLT revealed a mean sleep latency of 2.5 minutes and four sleep-onset REM periods, with positive HLA-DQB1*0602 typing.

Implications:

  • The combination of clinical history, PSG, and MSLT facilitated the diagnosis of narcolepsy with cataplexy.
  • This case underscores the presentation of early-onset narcolepsy with excessive sleepiness and cataplexy in young children.

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.

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).

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...

Restless Leg Syndrome and Night Terrors

Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...
