Loss of Insight in Syndromes Associated with Frontotemporal Lobar Degeneration: Clinical and Imaging Features.
Am J Geriatr Psychiatry
December 2024
Department of Clinical and Experimental Sciences (DA, BB), University of Brescia, Brescia, Italy; Molecular Markers Laboratory (BB), IRCCS Istituto Centro San Giovanni di Dio Fatebenefratelli, Brescia, Italy. Electronic address:
Objectives: The present study aims to assess the prevalence, associated clinical symptoms, longitudinal changes, and imaging correlates of Loss of Insight (LOI), which is still unexplored in syndromes associated with Frontotemporal Lobar Degeneration (FTLD).
Design: Retrospective longitudinal cohort study, from Oct 2009 to Feb 2023.
Setting: Tertiary Frontotemporal Dementia research clinic.
Pragmatic Algorithm for Visual Assessment of 4-Repeat Tauopathies in [F]PI-2620 PET Scans.
Neuroimage
January 2025
Department of Nuclear Medicine, University Hospital, LMU Munich, Munich, Germany; German Center for Neurodegenerative Diseases (DZNE) Munich, Munich, Germany. Electronic address:
Aim: Standardized evaluation of [F]PI-2620 tau-PET scans in 4R-tauopathies represents an unmet need in clinical practice. This study aims to investigate the effectiveness of visual evaluation of [F]PI-2620 images for diagnosing 4R-tauopathies and to develop a straight-forward reading algorithm to improve objectivity and data reproducibility.
Methods: A total of 83 individuals with [F]PI-2620 PET scans were included.
Protective role of apolipoprotein A and B in Parkinson's disease: A prospective study from UK Biobank.
Parkinsonism Relat Disord
January 2025
Department of Neurology, Laboratory of Neurodegenerative Disorders, National Clinical Research Center for Geriatric, West China Hospital, Sichuan University, Chengdu, China. Electronic address:
Introduction: Evidence have indicated relation between apolipoproteins and neurodegenerative disorders (NDDs). However, previous studies have produced inconsistent results, and a comprehensive analysis of apolipoproteins in NDDs is currently lacking.
Methods: Using Cox proportional hazards regression analysis based on data from UK Biobank, we examined the association between baseline serum levels of apolipoprotein A (ApoA) and apolipoprotein B (ApoB) and risk of Parkinson's disease (PD), Alzheimer's disease, amyotrophic lateral sclerosis, frontotemporal dementia, and multiple sclerosis.
Prospective Multicenter Evaluation of the MDS "Suggestive of PSP" Diagnostic Criteria.
Mov Disord
January 2025
Department of Neurology, LMU University Hospital, Ludwig-Maximilians-Universität (LMU) München, Munich, Germany.
Background: The recent Movement Disorders Society (MDS)-progressive supranuclear palsy (PSP) diagnostic criteria conceptualized three clinical diagnostic certainty levels: "suggestive of PSP" for sensitive early diagnosis based on subtle clinical signs, "possible PSP" balancing sensitivity and specificity, and "probable PSP" highly specific for PSP pathology.
Objective: The aim of this study was to prospectively validate the criteria against long-term clinical follow-up and characterize the diagnostic certainty increase over time.
Methods: Patients with "possible PSP" or "suggestive of PSP" diagnosis and clinical follow-up were recruited in two German multicenter longitudinal observational studies (ProPSP and DescribePSP).
Mechanism of P-Hydroxy Benzyl Alcohol Against Cerebral Ischemia Based on Metabonomics Analysis.

Stroke is the leading cause of death and disability worldwide, with ischemic stroke accounting for the majority of these. HBA is the active ingredient in and has potential therapeutic effects on central nervous system diseases. In this study, the cell model of cerebral ischemia was replicated by the culture method of oxygen-glucose deprivation/reoxygenation, and the rat model of vascular dementia was established by the two-vessel occlusion method.
