Frontotemporal dementia is an important neurodegenerative disorder accounting for a significant proportion of dementia cases with onset before 60 years of age. Apart from the well recognized behavioral changes the disease has many other distinctive features like predominant language involvement
V.H., a 68-year-old right-handed woman, presented with a progressive deterioration in her ability to recognize faces of familiar people, including friends and relatives. Neuropsychological testing on two occasions separated by 9 months indicated no deterioration in general intellectual ability from
F.G., a 71-year-old right-handed man, presented with a slowly progressive deterioration in his ability to recognize faces of familiar and famous persons, contrasting with the relative preservation of other cognitive domains. His primary face perception skills were intact. Along with his
We present the case of a 78 year old man admitted to the hospital with progressive memory disorder. Neuropsychological examination showed inability to recognize familiar faces (prosopagnosia). MRI documented cortical atrophy, which did not explain the neurological deficit. CT did not show
Patients with posterior cortical atrophy may have dorsal visual system (occipital-parietal) dysfunction (optic ataxia, visuospatial disorientation, and simultanagnosia), ventral visual system (occipital-temporal) dysfunction (pure alexia, prosopagnosia, visual anomia, and agnosia), or both. We
OBJECTIVE
In posterior cortical atrophy (PCA), visual hallucinations are rare symptoms and mirror sign has not been described.
METHODS
Single case report.
RESULTS
We reported a 60-year-old woman with PCA who reported complex visual hallucinations, such as a man walking in her room, and mirror sign,
We describe clinical and biomarker findings in an index patient with the onset of Alzheimer's disease (AD) symptoms at age 57 and a family history consistent with an autosomal dominant pattern of inheritance. She had the atypical early features of visual agnosia and prosopagnosia followed by
BACKGROUND
Posterior cortical atrophy (PCA) is a clinically and radiologically defined syndrome, in which predominant symptoms focus on higher visual dysfunction with progressive course and association with cortical atrophy or hypometabolism that predominates in the posterior part of the
A case of "apractognosia", a syndrome of minor hemisphere, and prosopagnosia was described. A 68 years old, right handed, hypertensive man who had experienced an episode of left hemiparesis of several weeks' duration developed a syndrome of minor hemisphere, metamorphopsia, visuoconstructive
Prosopagnosia, the inability to recognize faces, has a history going back to Charcot and Hughlings-Jackson, but was first named by Bodamer in 1947. Its anatomical loci are still unclear. However, progressive prosopagnosia is normally linked to right dominant temporal lobe atrophy, and diagnosed as
Covert person recognition was investigated longitudinally over a three-year period in a patient suffering from "Crossmodal Familiar Person Agnosia", possibly due to a fronto-temporal dementia in its right temporal variant (Gentileschi et al., 2001). The progressive neuronal degeneration in the
OBJECTIVE
Variants of frontotemporal lobar degeneration (FTLD) are associated with distinct clinical, pathological, and neuroanatomical profiles. Lines of emerging research indicate a rare variant with focal atrophy of the right temporal lobe (RTLA). The objective was to present case data and
Posterior cortical atrophy (PCA) is a syndrome that involves distinct neuropsychological deficits. This paper presents the clinical and neuropsychological findings recorded in four patients with PCA and reviews the characteristics of the syndrome and other conditions that need to be considered in
