Early cortical atrophy in REM sleep behavior disorder.

Introduction: The presence of cortical atrophy (focal or diffuse) prior to the development of symptoms of cognitive impairment could predict the earliest cases of neurodegenerative disease in patients with REM sleep behavior disorder (RSBD). We reviewed the usefulness of cranial CT and MRI as early markers of cortical atrophy in patients with RSBD at our center.

Patients And Methods: Retrospective observational descriptive analysis of patients diagnosed with RSBD from October 2012 to October 2022.

Translating NIA-AA criteria into usual practice: Report from the ReDeMa Project.

Introduction: Biomarker-informed criteria were proposed for the diagnosis of Alzheimer's disease (AD) by the National Institute on Aging and the Alzheimer's Association (NIA-AA) in 2011; however, the adequacy of this criteria has not been sufficiently evaluated.

Methods: ReDeMa () is a regional cohort of patients attending memory and neurology clinics. Core cerebrospinal fluid biomarkers were obtained, NIA-AA diagnostic criteria were considered, and changes in diagnosis and management were evaluated.
