Summary
Patients with narcolepsy with cataplexy (NC) have significantly higher rates of sleep-related eating disorder (SRED) and nocturnal smoking (NS). These compulsive nocturnal behaviors are strongly associated with NC, indicating a need for further investigation and management strategies.
Area of Science:
- Neurology
- Sleep Medicine
- Psychiatry
Background:
- Narcolepsy with cataplexy (NC) is a chronic neurological disorder affecting sleep-wake cycles.
- Compulsive behaviors, such as sleep-related eating disorder (SRED) and nocturnal smoking (NS), can significantly impact quality of life.
- The prevalence and association of SRED and NS in NC patients are not well-established.
Purpose of the Study:
- To determine the prevalence of SRED and NS in adult patients diagnosed with narcolepsy with cataplexy.
- To compare the occurrence of SRED and NS in NC patients versus a matched control group.
- To explore potential psychopathological traits associated with SRED and NS in NC.
Main Methods:
- A case-control study was conducted at a university hospital.
- Sixty-five adult NC patients and 65 matched controls completed validated questionnaires.
- Assessments included SRED, NS, restless legs syndrome (RLS), and psychopathological profiles (EDI-2, MOCI, BDI).
Main Results:
- NC patients exhibited significantly higher prevalence rates of SRED (32% vs 3%), NS (21% vs 0%), and RLS (18% vs 5%) compared to controls.
- NC patients showed increased eating disorder pathology (80% vs 46%) and depression (41% vs 18%).
- SRED and NS in NC patients were associated with specific psychopathological traits, including bulimia, social insecurity, perfectionism, and obsessive-compulsiveness.
Conclusions:
- This study demonstrates a strong association between SRED and NS and narcolepsy with cataplexy in adults.
- The findings highlight the importance of screening for these compulsive nocturnal behaviors in NC patients.
- Further research is warranted to understand the underlying mechanisms and develop targeted interventions.

01:07Narcolepsy
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.
01:24Sleep-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:

01:15REM 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.

01:17Sleepwalking and Sleep Talking
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...

01:21Sleep Apnea
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

01:28Obsessive-Compulsive Disorder
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
