Abstract

IMPORTANCE: Sleep disturbances are recognized as a common nonmotor complaint in Parkinson disease but their etiology is poorly understood. OBJECTIVE: To define the sleep and circadian phenotype of patients with early-stage Parkinson disease. DESIGN, SETTING, AND PARTICIPANTS: Initial assessment of sleep characteristics in a large population-representative incident Parkinson disease cohort (N=239) at the University of Cambridge, England, followed by further comprehensive case-control sleep assessments in a subgroup of these patients (n=30) and matched controls (n=15). MAIN OUTCOMES AND MEASURES: Sleep diagnoses and sleep architecture based on polysomnography studies, actigraphy assessment, and 24-hour analyses of serum cortisol, melatonin, and peripheral clock gene expression (Bmal1, Per2, and Rev-Erbα). RESULTS: Subjective sleep complaints were present in almost half of newly diagnosed patients and correlated significantly with poorer quality of life. Patients with Parkinson disease exhibited increased sleep latency (P = .04), reduced sleep efficiency (P = .008), and reduced rapid eye movement sleep (P = .02). In addition, there was a sustained elevation of serum cortisol levels, reduced circulating melatonin levels, and altered Bmal1 expression in patients with Parkinson disease compared with controls. CONCLUSIONS AND RELEVANCE: Sleep dysfunction seen in early Parkinson disease may reflect a more fundamental pathology in the molecular clock underlying circadian rhythms.

  • Compared with healthy aged people, individuals with AD or PD show considerably lower melatonin rhythm amplitudes and excessive sleepiness, as well as other sleep-wake cycle disturbances, such as later sleep onsets.

    “Compared with healthy aged people, individuals with AD or PD show considerably lower melatonin rhythm amplitudes and excessive sleepiness, as well as other sleep–wake cycle disturbances, such as later sleep onsets254–258.”
  • In a cohort of 239 individuals with Parkinson's disease, sleep latency is significantly increased, sleep efficiency and REM are reduced, melatonin levels are reduced, and BMAL1 serum expression rhythms are lost.

    “This study shows significantly increased sleep latency, reduced sleep efficiency and reduced REM, along with reduced melatonin levels and a loss of BMAL1 serum expression rhythms, in a cohor of 239 individuals with PD.”
  • A lack of time-dependent variation in Bmal1 expression in Parkinson's disease patients was recently confirmed in another study.

    “A lack of time-dependent variation in Bmal1 expression in PD patients was recently confirmed in another study (Breen et al., 2014).”

  • Both studies reported decreased amplitude of melatonin secretion in Parkinson's disease.

    “However, both studies reported decreased amplitude of melatonin secretion.”

  • Two other recent studies did not show alterations in the circadian phase of melatonin secretion in Parkinson's disease.

    “Two other recent studies did not show alterations in the circadian phase of melatonin secretion (Breen et al., 2014, Videnovic et al., 2014a, Videnovic et al., 2014b).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
