Rem Sleep Without Atonia

Abstract Background Isolated REM sleep without atonia (RSWA) as a main polysomnograhic feature of REM sleep behaviour disorder (RBD) is thought to be a prodromal or subclinical state of the disease. RSWA/RBD occurence in psychiatric population is much more frequent than in general population but its associated factors are still not known. Methods We invited 88 psychiatry in-patients to undervent video-polysomnography. The visual scoring was focused on RSWA in submentales and flexores digitales superficiales muscles. This parametr was subsequently correlated mainly with age/gender, their medication and mental status. Results The RWSA was mostly still in normal range despite the fact, that selected psychiatry patients (≤ 50 years) were taking several classes of psychoactive medication. 3,6% had convincingly RBD, although 35.7% reported rare lifetime occurence of dream-enacting behaviour and 62.8% sporadic nightmares. We found correlation between RSWA and SNRI medication class (p = 0.015), specifically venlafaxine (p = 0.029) as well as quetiapine (p = 0.030). Another significant associated factors were current anxiety (p < 0.001) and depressive symptoms (p = 0.05), but we found no relation between RSWA and given diagnosis. Conlucions Isolated RSWA in younger psychiatry patients might be a result of multiple factors, including medication and current mental status but these factors are in most cases not sufficient to manifest RBD.

Abstract Introduction While REM sleep without atonia (RSWA) in REM sleep behavior disorder (RBD) is associated with male sex, age greater than or equal to 50 years, alpha-synucleinopathies, and narcolepsy, the characteristics of patients with RSWA/persistent periodic limb movements of sleep in REM sleep (RSWA/PLMS-REM) without dream enactment behaviors are unexplored. The aim of this study was to compare the demographics, comorbidities, and concomitant medication use between RSWA/PLMS-REM patients and non-RSWA/non-PLMS-REM controls. Based on anecdotal clinical observations, we hypothesized that these patients are more commonly young, women, have psychiatric or neurological diseases, and use antidepressants. Methods We conducted a retrospective review of the Mayo Clinic electronic medical record to identify all patients with RSWA/PLMS-REM between November 2018 and November 2020. After excluding all patients with RBD, restless legs syndrome, narcolepsy, and RSWA/non-PLMS-REM, we identified 27 patients. All in-lab polysomnograms (PSGs) were reviewed to calculate the periodic limb movement index per hour of REM sleep (REM-PLMI). We also identified a control group of 15 individuals without RSWA, reviewed their PSGs, and calculated the REM-PLMI. Results The mean REM-PLMI of patients with RSWA was 64 +/- 8.3 (standard error of mean (SEM)) per hour versus 1 +/- 0.6 (SEM) per hour in non-RSWA controls (p &lt; 0.001). Patients with RSWA/PLMS-REM and non-RSWA controls had similar age and gender, 62 +/- 3 (SEM) versus 58 +/- 3 (SEM) years and 81% versus 87% men, respectively. However, psychiatric diagnosis, neurological disorders, and antidepressants use were more common among RSWA/PLMS-REM patients compared to non-RSWA controls with p = 0.0002, p = 0.0035 and p = 0.0074 respectively (Fisher’s Exact Test). Conclusion Psychiatric diagnosis, neurological disorders, and antidepressant use are more common among RSWA/PLMS-REM patients compared to non-RSWA/non-PLMS-REM controls. Further research to determine the implications of a diagnosis of RSWA/PLMS-REM for the future development of alpha-synucleinopathies are needed and currently ongoing. Support (if any):

Neuroleptic drugs cause many forms of extra-pyramidal syndromes. One of these, tardive dyskinesia,1 occurs only after the patient has been taking the drug for some time (‘tardive’ refers to the late onset). The movements are involuntary and repetitive usually involving the face and tongue, but they may also affect the limbs and trunk. Tongue protrusion, licking and smacking of the lips, sucking and chewing movements, grimacing, grunting, blinking and furrowing of the forehead have all been described and attributed to long-continued medication with neuroleptic drugs of the phenothiazine, butyrophenone and thioxanthene groups. The patient can inhibit the movements, but anxiety makes them worse. Many of these symptoms were noticed in schizophrenic patients before neuroleptic drugs were introduced2 and they can occur in otherwise normal untreated elderly people. Nevertheless it is generally accepted that in most cases tardive dyskinesia is an unwanted effect of neuroleptic medication. Despite suggestions to the contrary, the abnormal movements are not necessarily associated with high dosage of neuroleptic drugs or with pre-existing brain damage.3 4 Tardive dyskinesia has been reported in 3–6% of a mixed population of psychiatric patients5 and over half of a group of chronic schizophrenics on long-term treatment.4 The more careful the neurological examination, the greater the apparent incidence.

Rem Sleep Without Atonia

Abstract Purpose Compare agreements between polysomnography-based (PSG) diagnosis of isolated REM-sleep-behavior-disorder (iRBD) and Non-REM-Hypertonia (NRH), a novel biomarker independently associated with synucleinopathy-related neurodegenerative diseases. Methods Sixteen patients with histories of dream-enactment-behavior (DEB)(women=38%; age:64.6±13.0) underwent PSG with simultaneously-recorded Sleep Profiler (SP). Two boarded sleep neurologists independently characterized iRBD. Physician1 combined abnormal qualitative REM-sleep-without-atonia (RSWA) by submental electromyography, with video-confirmation of probably DEB. Physician2 relied solely on qualitative RSWA. SP was auto-staged, technically reviewed, and reprocessed for automated abnormal NRH detection. Kappa scores measured physician and NRH agreements. Results In the 14 records with REM sleep, iRBD was characterized in: Physician1=64%, Physician2=79%, NRH=71% of the records. Across the three methods, unanimous iRBD agreement occurred in 57% of the records (positive=7, negative=1). The between-physician agreement in iRBD classifications was fair (kappa=0.32). The agreement between NRH and Physician1 was moderate (kappa=0.52) versus slight with Physician2 (kappa=0.05). NRH comparisons to consensus physician agreement yielded one false-positive and one false-negative iRBD finding. Physician2 classified: a) iRBD in two cases that were negative by Physician1 and NRH, and b) one negative case that Physician1 and NRH characterized as iRBD. Physician1 identified one negative case that was classified iRBD by Physician2 and NRH. Additionally, NRH was abnormal in one of the two records with no REM sleep. Discussion NRH may assist in iRBD risk assessment, given it agreed with at least one physician in 86% of the cases and the between-physician iRBD agreement was only fair. NRH also characterized iRBD-risk in patients with insufficient REM sleep for RSWA assessment.
