AI Article Synopsis

  • - The study investigated the prevalence of probable rapid eye movement sleep behavior disorder (pRBD) among middle-aged and older adults visiting a psychiatric outpatient clinic, finding that 15.9% of participants screened positive for pRBD.
  • - A survey of 2907 individuals aged 45-80 revealed that factors like chemical exposure, family history of psychotic disorders, delayed mental health care, and certain medications were linked to an increased likelihood of having pRBD.
  • - The research underscores the need for clinicians to identify sleep behavior disorders in patients with mental health issues, particularly those with neurological and mood-related disorders.

Article Abstract

Objective: Rapid eye movement sleep behavior disorder (RBD) is often underdiagnosed among people living with mental disorders. The present study aimed to investigate the prevalence of probable RBD (pRBD) and its associated factors among middle-aged and older adults in a psychiatric outpatient clinic.

Methods: We conducted a cross-sectional survey among 2907 people aged 45-80 years who visited the outpatient clinic between March 1 and August 31, 2022 in a psychiatric hospital. A cutoff score ≥5 on the RBD Screening Questionnaire (RBDSQ) was used to indicate the presence of probable RBD (pRBD). Potential factors associated with pRBD were also assessed with a structured checklist. The association between these factors and the presence of pRBD was examined with logistic regression.

Results: The response rate was 64.3 %. Among 1868 respondents [age 58.5 ± 9.6 years, male n = 738 (39.5 %), female n = 1130 (60.5 %)], 15.9 % (95 % CI 14.2-17.6 %) screened positive for pRBD. Occupational exposure to chemicals; positive family history of psychotic disorders; a late start of mental health care; a medical history of autonomic dysfunction; mood problems; and use of antidepressants, hypnotics, and acetylcholinesterase inhibitors were associated with an increased likelihood of having pRBD (P < 0.05 for all).

Conclusion: pRBD is common among outpatients with mental disorders, especially in mental disorders due to neurological diseases and physical conditions, mood disorders and anxiety or somatoform disorders. The findings highlight the importance of identifying sleep behavior disorders among people living with mental disorders in clinical practice.
