“…Other abnormalities of state boundaries, whereby elements of one state of being intrude into another, have been reported and have been considered as elemental forms of SD: hallucinations and narcolepsy after sleep‐deprivation, lucid dreaming, and even NREM parasomnias such as the confusional arousals 1, 2. As for the lesion site, abnormal REM sleep without atonia and RBD were reported with pontine lesions in human patients10, 11 and lesioning the dorsal pontine tegmentum in the cat released muscle tone and motor behaviour during REM sleep 12–15. In our patient, however, RBD were only part of the clinical picture.…”

After surgery for a tegmental ponto-mesencephalic cavernoma, a patient developed sleep-related excessive fragmentary myoclonus, diffuse myoclonic jerks, simple quasipurposeful movements of the limbs, and rapid eye movement (REM) sleep behaviour disorder as motor features of status dissociatus, a condition in which elements of one state of being (wake, NREM and REM sleep) pathologically intrude into another.

Narcolepsy involves abnormalities of rapid-eye-movement (REM) sleep, including a short latency to the onset of REM sleep, hypnagogic hallucinations, and sleep paralysis. In addition, persistence of muscle tone by electromyographic criteria or excessive muscle twitching during REM sleep or both have been reported in treated and untreated narcoleptic patients. We report that another previously described abnormality of REM sleep, REM sleep behavior disorder, may also be a symptom of narcolepsy. This disorder was found in 10 narcoleptic patients during routine clinical evaluations involving polysomnography and multiple sleep latency tests. During REM sleep, 7 additional narcoleptic patients displayed persistent muscle tone and/or excessive twitching, which we believe to be subclinical components of REM sleep behavior disorder. These 17 patients, diagnosed by established criteria for narcolepsy and for REM sleep behavior disorder, ranged in age from 8 to 74 years. Seventy-one percent were male. Narcolepsy and REM sleep behavior disorder most commonly emerged in tandem. In 3 patients, treatment of narcolepsy-cataplexy with stimulants and tricyclics either induced or exacerbated REM sleep behavior disorder.
