Optical coherence tomography is a simple, high-resolution technique to quantify the thickness of retinal nerve fiber layer (RNFL). Previous studies have shown that degenerative changes occur in optic nerve fibers and are manifested as thinning of RNLF in patients with Alzheimer's disease (AD). However, there are no studies on the thickness of the RNLF in(More)
The logopenic variant of primary progressive aphasia (lvPPA) has been associated with Alzheimer disease, although this relationship is still subject to debate. The purpose of this study is to determine the frequency of amyloid biomarkers in patients with lvPPA, and record any potential clinical or topographic differences between patients with and without(More)
Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is an uncommon neuro-ophthalmologic syndrome consisting of both eyes primary position exotropia and bilateral internuclear ophthalmoplegia. It is thought to be caused by medial midbrain lesions involving both bilateral medial longitudinal fasciculi and medial rectus subnuclei. We report the clinical(More)
OBJECTIVE Apathy is one of the most common and disabling syndromes of dementia and presents at all stages of the disease. Comprehensive and structured methods to assess apathy in dementia are still needed. Lille's Apathy Rating Scale (LARS) has shown good psychometric properties for apathy evaluation in Parkinson disease but has not been validated in(More)
BACKGROUND AND PURPOSE Although primitive reflexes (PRs) are inhibited during the first years of childhood, they may reappear with brain injury. PRs have been linked to frontal lobe dysfunction, but their precise topography has not yet been defined. The purpose of this study was to map which regions of the brain display a reduced glucose metabolism in(More)
BACKGROUND Positron emission tomography (PET) images with amyloid tracers show normal uptake in healthy white matter, which suggests that amyloid tracers are potentially useful for studying such white matter diseases as multiple sclerosis (MS). METHODS Twelve patients diagnosed with MS (5 with RRMS, 5 with SPMS, and 2 with PPMS) and 3 healthy controls(More)
INTRODUCTION Lobar frontotemporal degeneration (FTLD) encompasses a group of molecular disease defined by the deposition of an abnormal protein in the central nervous system. Behavioural variant frontotemporal dementia (bvFTD) is the most frequent clinical presentation of FTLD. The past two decades of research have contributed to a better understanding of(More)
Primary progressive aphasia (PPA) may be the onset of several neurodegenerative diseases. This study evaluates a cohort of patients with PPA to assess their progression to different clinical syndromes, associated factors that modulate this progression, and patterns of cerebral metabolism linked to different clinical evolutionary forms. Thirty-five patients(More)
BACKGROUND New consensus criteria have been proposed to classify primary progressive aphasia (PPA) into three variants: agrammatic, semantic, and logopenic. Some studies have subsequently addressed the usefulness of these criteria, with controversial results. We aimed to determine the correlation between the clinical diagnosis according to the new criteria(More)
Diagnosing progressive primary aphasia (PPA) and its variants is of great clinical importance, and fluorodeoxyglucose (FDG) positron emission tomography (PET) may be a useful diagnostic technique. The purpose of this study was to evaluate interobserver variability in the interpretation of FDG PET images in PPA as well as the diagnostic sensitivity and(More)
