Nightmares in narcolepsy: underinvestigated symptom?

Abstract

Objective Besides main disease symptoms, disturbing dreams are often found in narcoleptics and may contribute to disturbed sleep. Our main goal was to study different types of oneiric activity in narcolepsy with cataplexy (NC) and narcolepsy without cataplexy (N).Methods We have analyzed the medical history of 118 narcoleptics (64 men, 86 with NC, 32 with N, mean age 41.6±15 years). Their most frequent dreams were divided into four groups: (A) low recall/mundane dreams, (B) vivid dreams without disturbing negative emotion, (C) nightmares, (D) reduction of nightmares, possibly by medication. Associations with other features of the disease were statistically analyzed.Results Nightmares were found in one-third of the patients, proportionally distributed in N and NC groups; not negatively charged vivid dreams appeared more frequently in NC patients (P<0.005). No/mundane dreams occurred with higher prevalence in men (48%) than in women (20%), (P<0.005), without any significant influence of age. Occurrence of nightmares was significantly higher in patients with REM sleep behavior (P<0.05), but lower in patients with obstructive sleep apnea (P<0.005). Polysomnographic correlation of N and NC nightmare groups showed more wakefulness (P<0.05) and higher percentage of NREM1 stage (P<0.05) in NC patients with nightmares.Conclusion Compared with the general population, nightmares seem to be significantly more prevalent in both NC and N, and they are not sufficiently investigated and treated. The neurobiological basis of narcolepsy and patients' dreaming activities appear to be closely related.

  • The percentage of nightmares in the narcoleptic group was 33%.

    “It has been found that the percentage of nightmares in the narcoleptic group was 33% (Pisko et al., 2014), while the prevalence of nightmares in general population was around 5% (Li et al., 2010; Sandman et al., 2013).”

  • Nightmares occur with a certain frequency in narcolepsy, likely because of daytime stress due to impairments caused by narcolepsy.

    “Also, nightmares seem to occur with a certain frequency in this population (Schredl, 1998; Schredl et al., 2012; Pisko et al., 2014), likely because of daytime stress due to the impairments caused by narcolepsy (Rak et al., 2015).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
