Posterior cortical atrophy is a dementia syndrome with symptoms of cortical visual dysfunction, associated with amyloid plaques and neurofibrillary tangles predominantly affecting visual association cortex. Most patients diagnosed with posterior cortical atrophy will finally develop a typical Alzheimer's disease. However, there are a variety of(More)
BACKGROUND Primary progressive aphasia (PPA) is a progressive language disorder associated with atrophy of the dominant language hemisphere, typically left. Current PPA criteria divide PPA into three variants: non-fluent (nfvPPA), semantic (svPPA) and logopenic (lvPPA). The classification of PPA into one of the three variants may be performed at 3 levels:(More)
OBJECTIVES Patients with frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17) may be agraphic. The study aimed at characterizing agraphia in individuals with a P301L MAPT mutation. METHODS Two pairs of siblings with FTDP-17 were longitudinally examined for agraphia in relation to language and cognitive deficits. RESULTS All(More)
BACKGROUND According to recent investigations, the eradication of Helicobacter pylori (H. pylori) may influence levodopa (LD) pharmacokinetics (PK) and improve the motor function of infected patients with Parkinson disease (PD). The aim of this study was to compare PK of LD and its metabolite 3-O-methyldopa (3-OMD), between H. pylori-positive (HP+) and(More)
Fluent primary progressive aphasia (fPPA) is very often confused with semantic dementia (SD), due to the ambiguity of the latter term. We present a case of fPPA with neuropsychological and neuroimaing data, not fulfilling the diagnostic criteria for SD. The language disturbance profile is presented, resembling transcortical sensory aphasia. The results of(More)
Olfactory dysfunction is associated with normal aging, multiple neurodegenerative disorders, including Parkinson's disease, Lewy body disease and Alzheimer's disease, and other diseases such as diabetes, sleep apnea and the autoimmune disease myasthenia gravis. The wide spectrum of neurodegenerative disorders associated with olfactory dysfunction suggests(More)
Although the clinical and neuroanatomical characteristics of behavioral and personality changes have been well-defined in frontotemporal dementia syndromes, relatively little is known about the behavioral and personality changes in frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17). Thus, the aim of this study was to longitudinally(More)
BACKGROUND The overlap between progressive supranuclear palsy (PSP) and progressive non-fluent aphasia (PNFA) is being increasingly recognized. In this paper descriptive writing in patients with Richardson syndrome of progressive supranuclear palsy (PSP-RS) is compared to writing samples from patients with PNFA. METHODS Twenty-seven patients participated(More)
A drawing may elucidate a cognitive profile in neurodegenerative conditions, as illustrated here. A 64-year-old woman with early-onset Alzheimer disease exhibited impaired visual perception (poor copying), which contrasted with good access to acquired constructional representations or motor routines (well-constructed spontaneous drawings) (figure 1).
