Article Synopsis
  • - The study investigates isolated REM sleep behavior disorder (iRBD) and its links to neurodegenerative diseases, focusing on gender differences and younger adults, which are less explored compared to older males.
  • - Researchers followed 372 participants (186 women and 186 men with iRBD), finding that women were diagnosed at a younger age than men and that over 12% converted to a neurodegenerative disorder within roughly 6 years.
  • - Key findings indicate that older age at diagnosis is a significant factor for phenoconversion risk, with lower risk observed in those using antidepressants or having chronic pain, while higher risk was noted in individuals with vascular issues.

Background And Objectives: REM sleep behavior disorder (RBD) is a parasomnia characterized by dream enactment. The International RBD Study Group developed the RBD Symptom Severity Scale (RBDSSS) to assess symptom severity for clinical or research use. We assessed the psychometric and clinimetric properties of the RBDSSS in participants enrolled in the North American Prodromal Synucleinopathy (NAPS) Consortium for RBD.

Introduction: Autonomic dysfunction is common in α-synucleinopathies such as Lewy Body dementias (LBD), Parkinson's disease (PD), and isolated REM Sleep Behavior Disorder (iRBD). We analyzed pulse-rate changes during sleep to index autonomic nervous system (ANS) dysfunction in patients with α-synucleinopathies vs. non-synucleinopathy groups expected to have normal ANS function.

β-Amyloid Load on PET Along the Continuum of Dementia With Lewy Bodies.

Background And Objectives: β-Amyloid (Aβ) plaques can co-occur with Lewy-related pathology in patients with dementia with Lewy bodies (DLB), but Aβ load at prodromal stages of DLB still needs to be elucidated. We investigated Aβ load on PET throughout the DLB continuum, from an early prodromal stage of isolated REM sleep behavior disorder (iRBD) to a stage of mild cognitive impairment with Lewy bodies (MCI-LB), and finally DLB.

Methods: We performed a cross-sectional study in patients with a diagnosis of iRBD, MCI-LB, or DLB from the Mayo Clinic Alzheimer Disease Research Center.

Endothelial Cells Induced Progenitors Into Brown Fat to Reduce Atherosclerosis.

Circ Res

July 2022

Dianne Nunnally Hoppes Laboratory (K.P., Q.L., H.Y., E.M., T.S., R.S.L., Q.L., S.K., J.F., H.P., I.-H.W., M.G.Y., H.S., G.L.K.), Harvard Medical School, Boston, MA.

Background: Insulin resistance (IR) can increase atherosclerotic and cardiovascular risk by inducing endothelial dysfunction, decreasing nitric oxide (NO) production, and accelerating arterial inflammation. The aim is to determine the mechanism by which insulin action and NO production in endothelial cells can improve systemic bioenergetics and decrease atherosclerosis via differentiation of perivascular progenitor cells (PPCs) into brown adipocytes (BAT).

Methods: Studies used various endothelial transgenic and deletion mutant mice of insulin receptors, eNOS (endothelial NO synthase) and ETBR (endothelin receptor type B) receptors for assessments of atherosclerosis.

REM sleep atonia loss distinguishes synucleinopathy in older adults with cognitive impairment.

Neurology

January 2020

From the Mayo Center for Sleep Medicine (S.J.M., G.M.T., D.J.S., P.C.T., K.L.J., A.R.M., R.S., M.M.M., B.F.B., M.H.B., E.K.S.L.) and Departments of Neurology (S.J.M., P.V., B.F.B., M.H.S., E.K.S.L.), Health Science Research (R.S., M.M.M.), Psychology (M.M.M.), Radiology (K.K.), and Medicine (E.K.S.L.), Mayo Clinic and Foundation, Rochester, MN; Department of Neurology (H.-Y.J.), Providence Neurological Specialties-West, Portland, OR; and University of Minnesota Duluth (A.R.M.).

Objective: To determine whether quantitative polysomnographic REM sleep without atonia (RSWA) distinguishes between cognitive impairment phenotypes.

Background: Neurodegenerative cognitive impairment in older adults predominantly correlates with tauopathy or synucleinopathy. Accurate antemortem phenotypic diagnosis has important prognostic and treatment implications; additional clinical tools might distinguish between dementia syndromes.
