Howl: Nightmare or REM Sleep Behavior Disorder?

Nightmare disorder consists of the appearance of unpleasant and vivid, repeated dreams, with a situation of discomfort and anguish on awakening. Its prevalence is 3%-4% in adults. They do not associat... We present the case of a 41-year-old man referred for vivid and unpleasant dreams, beginning in the last year, related to work stress.... The polysomnography showed the loss of atony in the REM phase and emission of a prolonged howl after which the patient continues in the REM phase.... Prolonged howling is a very rare symptom in sleep disorders, and very atypical in RSBD, so polysomnography is essential to confirm the diagnosis and rule out other parasomnias....

Clinical and neuroimaging markers of neurodegeneration in first-degree relatives of patients with REM sleep behavior disorder with and without isolated rapid eye movement sleep without atonia: A case-control clinical and dopamine PET study.

The current study aimed to examine the neurodegenerative implication of isolated REM sleep without atonia (RSWA) among first-degree relatives of patients with REM sleep behaviour disorder (RBD).... This cross-sectional case-control study recruited three groups of subjects: First-degree relatives of RBD patients with isolated RSWA (n = 17), first-degree relatives of RBD patients without isolated ... In contrary to our hypothesis, the three groups did not differ in their pre- or post-striatal dopaminergic transmission function, and their Prodromal Parkinson's Disease likelihood ratio. However, the... FDRs of RBD patients with isolated RSWA did not have increased neurodegenerative markers compared to FDRs of RBD patients without isolated RSWA and normal control, despite an paradoxical increase in f...

Oligomeric Alpha-Synuclein and STX-1A from Neural-Derived Extracellular Vesicles (NDEVs) as Possible Biomarkers of REM Sleep Behavior Disorder in Parkinson's Disease: A Preliminary Cohort Study.

REM sleep behavior disorder (RBD) has a tighter link with synucleinopathies than other neurodegenerative disorders. Parkinson's Disease (PD) patients with RBD have a more severe motor and cognitive im...

REM and NREM Sleep Parasomnia in Anti-NMDA Receptor Encephalitis.

Encephalitis with anti-N-methyl-d-aspartate receptor antibodies (anti-NMDARe) is a rare disorder characterized by cognitive impairment, psychosis, seizures, and abnormal movements. Abnormal behaviors ... Patients were monitored by video-polysomnography on a first night followed by multiple sleep latency tests and 18 hours of bed rest.... Two patients with anti-NMDARe developed during the acute and postacute phase parasomnias including REM sleep behavior disorder and continuous finalistic quiet gesturing during a mixed N2/R sleep. The ... Video-polysomnography avoids misdiagnosing these parasomnia behaviors for seizure or movement disorders and allows adequate treatment....

Imaging progressive peripheral and central dysfunction in isolated REM sleep behaviour disorder after 3 years of follow-up.

Most patients with isolated rapid eye movement sleep behaviour disorder (iRBD) convert to Parkinson's disease (PD), dementia with Lewy bodies, or multiple system atrophy within 15 years of diagnosis. ... Twenty-two iRBD patients were included at baseline and 14 participated in follow-up after 3 years. Colonic transit time (CTT) was examined using radio opaque markers, colonic volume was defined on abd... iRBD patients displayed increased CTT (p = 0.001) and colonic volume (p = 0.01) at follow-up compared to baseline. Furthermore, [123I]MIBG uptake and [18F]FDOPA uptake showed progressive reductions at... Using objective markers, the present study documented that intestinal dysfunction and cardiac sympathetic degeneration worsen in the majority of iRBD patients over a 3-year period. The absent correlat...

Early cortical atrophy in REM sleep behavior disorder.

The presence of cortical atrophy (focal or diffuse) prior to the development of symptoms of cognitive impairment could predict the earliest cases of neurodegenerative disease in patients with REM slee... Retrospective observational descriptive analysis of patients diagnosed with RSBD from October 2012 to October 2022. All with cranial CT or MRI, evaluated by a neuroradiologist.... 54 patients were included, 21 women (38.88%), 33 men (61.12%), mean age at diagnosis of RSBD: 69.04±12.625 years. Of the 54 patients, 44 (81.48%) had imaging tests consistent with their age, and 10 ha... Almost half of our series have developed a neurodegenerative disease in the first 10years of evolution. The majority of them presented global cortical atrophy measured by the GCA scale in the first ye...

Acetyl-DL-leucine in two individuals with REM sleep behavior disorder improves symptoms, reverses loss of striatal dopamine-transporter binding and stabilizes pathological metabolic brain pattern-case reports.

Isolated REM Sleep Behavior Disorder (iRBD) is considered a prodrome of Parkinson's disease (PD). We investigate whether the potentially disease-modifying compound acetyl-DL-leucine (ADLL; 5 g/d) has ...
