AI Article Synopsis

  • Fibrils of the protein α-synuclein are linked to diseases like Parkinson Disease, Lewy Body Dementia, and Multiple System Atrophy.
  • There has been extensive research on different forms of α-synuclein fibrils using solid-state NMR, with various resonance assignments documented.
  • This study presents new carbon and nitrogen assignments specific to fibrils derived from postmortem brain tissue of a Lewy Body Dementia patient.

Article Abstract

Fibrils of the protein α-synuclein (Asyn) are implicated in the pathogenesis of Parkinson Disease, Lewy Body Dementia, and Multiple System Atrophy. Numerous forms of Asyn fibrils have been studied by solid-state NMR and resonance assignments have been reported. Here, we report a new set of C, N assignments that are unique to fibrils obtained by amplification from postmortem brain tissue of a patient diagnosed with Lewy Body Dementia.

US clinical practice guidelines for the diagnostic evaluation of cognitive impairment due to Alzheimer's disease (AD) or a related dementia (ADRD) are two decades old. This evidence-based guideline was developed to empower all clinicians to implement a structured approach for evaluating a patient with symptoms that may represent clinical AD/ADRD. An expert workgroup conducted a review of 7374 publications (133 met inclusion criteria) and developed recommendations as steps in an evaluation process.

US clinical practice guidelines for the diagnostic evaluation of cognitive impairment due to Alzheimer's disease (AD) or AD and related dementias (ADRD) are decades old and aimed at specialists. This evidence-based guideline was developed to empower all-including primary care-clinicians to implement a structured approach for evaluating a patient with symptoms that may represent clinical AD/ADRD. Through a modified-Delphi approach and guideline-development process (7374 publications were reviewed; 133 met inclusion criteria) an expert workgroup developed recommendations as steps in a patient-centered evaluation process.

Proteomic signatures of Alzheimer's disease and Lewy body dementias: A comparative analysis.

Alzheimers Dement

December 2024

Department of Neurobiology, Care Sciences and Society, Center for Alzheimer Research, Division of Neurogeriatrics, Karolinska Institutet, BioClinicum, Stockholm, Sweden.

Introduction: We aimed to identify unique proteomic signatures of Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and Parkinson's disease dementia (PDD).

Methods: We conducted a comparative proteomic analysis of 33 post mortem brains from AD, DLB, and PDD individuals without dementia focusing on prefrontal, cingulate, and parietal cortices, using weighted gene co-expression network analyses with differential enrichment analysis.

Results: Network modules revealed hub proteins common to all dementias.

Co-pathologies modify hippocampal protein accumulation patterns in neurodegenerative diseases.

Alzheimers Dement

December 2024

Department of Laboratory Medicine and Pathobiology and Department of Medicine, University of Toronto, Toronto, Ontario, Canada.

Introduction: Limited research has extensively analyzed neurodegenerative disease-related protein deposition patterns in the hippocampus.

Methods: This study examined the distribution of proteins in hippocampal subregions across major neurodegenerative diseases and explored their relation to each other. The area density of phosphorylated tau (p-tau), amyloid beta (Aβ), α-synuclein, and phosphorylated TDP-43 protein deposits together with pyramidal cell density in each hippocampal subregion, including CA1-4, prosubiculum (ProS), and subiculum was assessed in 166 cases encompassing various neurodegenerative diseases.
