Optical Coherent Tomography as a Potential Biomarker for Logopenic Variant Primary Progressive Aphasia: A Cross‐Sectional Prospective Study [PDF]

open access: yesAlzheimers Dement
Abstract Background The logopenic variant of Primary Progressive Aphasia (lvPPA) is a neurodegenerative disorder affecting primarily language functions. In 86% of lvPPA cases, the underlying pathology is amyloidopathy, as seen in Alzheimer's disease (AD).

The Neural Basis of Logopenic Progressive Aphasia

open access: yesJournal of Alzheimer's Disease, 2012
Logopenic progressive aphasia (LPA) is defined clinically by impairments of naming and sentence repetition. The relationship between these impairments and their neural basis has, however, not yet been determined. We aimed to localize cortical thinning associated with naming and repetition deficits using cortical thickness measurements.

Structural, Microstructural, and Metabolic Alterations in Primary Progressive Aphasia Variants

open access: yesFrontiers in Neurology, 2018
Neuroimaging studies have described the brain alterations in primary progressive aphasia (PPA) variants (semantic, logopenic, nonfluent/agrammatic). However, few studies combined T1, FDG-PET, and diffusion MRI techniques to study atrophy, hypometabolism,

Diagnosing Dementia in the Clinical Setting: Can Amyloid PET Provide Additional Value Over Cerebrospinal Fluid? [PDF]

open access: yes, 2016
Cerebrospinal fluid (CSF) measures of amyloid and tau are the first-line Alzheimer's disease biomarkers in many clinical centers. We assessed if and when the addition of amyloid PET following CSF measurements provides added diagnostic value.
