State Dissociation

Wakefulness, rapid eye movement (REM) and non-REM sleep are not always mutually exclusive conditions, as commonly assumed. In some cases, the declaration of any state may be incomplete and states can fluctuate rapidly, resulting in peculiar behavioural syndromes such as narcolepsy, REM sleep behaviour disorder and status dissociatus. We briefly introduce this topic and discuss three suggestive clinical cases.

Rem Sleep Behaviour Disorder

BackgroundRapid eye movement (REM) sleep behaviour disorder is a relatively new diagnostic category. It has never before been associated with a treatable depressive condition.AimsTo repot on a 74-year-old man with a history of depression and REM sleep behaviour disorder, associated with mild cognitive impairment.MethodAssessment using brain CT, MRI, PET, electroencephalography, neuropsychological testing and nocturnal polysomnography.ResultsDepression was treated with sertraline. Sleep laboratory studies supported a diagnosis of REM sleep behaviour disorder, which was treated with clonazepam. Sleep apnoea, revealed later, was treated with nasal continuous positive airways pressure. Brain MRI showed mild atrophy, but neuropsychological testing indicated no progressive cognitive deterioration.ConclusionsThis case draws attention to REM sleep behaviour disorder and its potential interaction with depression and cognitive impairment, producing symptoms which can be mistaken for early dementia. The diagnosis of REM sleep behaviour disorder is easily missed, and it requires careful history-taking and sleep investigation in all suspected sufferers. Associated neurological, sleep and psychiatric conditions (including depression and cognitive impairment) may confound the diagnosis.

IntroductionBecause the association between rapid eye movement sleep behaviour disorder (RBD) and impulse control disorders (ICDs) in Parkinson’s disease (PD) has been debated, we assessed the sleep characteristics and the frequency of RBD using video-polysomnography (v-PSG) in patients with PD with versus without ICDs.MethodsEighty non-demented patients with PD consecutively identified during routine evaluation at three movement disorders centres were enrolled in a case–control study. Forty patients (22 men; mean age: 62.6±9.7 years, Hoehn & Yahr: 2.1±0.6) with one or more current ICDs were age-matched and sex-matched with 40 patients with no history of ICDs (22 men, mean age: 64.9±7.8 years, Hoehn & Yahr: 2.2±0.6). They underwent a detailed sleep interview followed by a full-night in-lab v-PSG. Sleep was scored blindly to ICDs condition and RBD diagnosis included a clinical complaint of enacted dreams and/or documented behaviour during rapid eye movement (REM) sleep, with the presence of quantified REM sleep without atonia (RSWA).ResultsPatients with ICDs had a higher arousal index and higher RSWA than those without ICDs (51.9%±28.2%vs 32.2±27.1%, p=0.004). In addition, RBD was more frequent in the ICD group (85%vs53%, p=0.0001). RBD was still associated with ICDs in a multivariate regression analysis including age of onset, PD duration and severity, treatment duration, levodopa-equivalent and dopamine agonist-equivalent daily doses and antidepressant use (OR: 4.9 (95% CI 1.3 to 18.5), p=0.02).ConclusionsThis large, controlled series of patients with PD with ICDs assessed by v-PSG confirms the association between ICDs and RBD. Increased surveillance of symptoms of ICDs should be recommended in patients with PD with RBD.

Purpose:To describe an association of Tourette's syndrome with rapid eye movement sleep behaviour disorder (RBD) in a prepubescent boy.Methods:A four year longitudinal single-case study.Results:The co-existence of Tourette's syndrome and RBD was confirmed after polysomnographic studies using the standard criteria. The authors propose possible overlap in the pathophysiological mechanisms underlying the two disorders.
