1/16. Progressive dysarthria. case reports and a review of the literature.Two patients presenting with progressive dysarthria as the single initial manifestation of a neurodegenerative condition are described. The nature of the dysarthria as well as the additional symptoms that developed in the course of the disorder are very different in these two cases. Nevertheless, neuroimaging findings are strikingly similar and suggest bilateral involvement of posterior inferior frontal lobe structures, mainly in the dominant cerebral hemisphere. The clinical syndrome of these patients can therefore be considered an example of frontotemporal degeneration presenting without dementia or compartmental alteration, at least in the early stages. This broadens the clinical spectrum of frontotemporal degeneration and demonstrates the need for a syndromal subclassification of this nosological entity.- - - - - - - - - - ranking = 1keywords = degeneration (Clic here for more details about this article) |
2/16. paraneoplastic cerebellar degeneration as the first manifestation of cancer.paraneoplastic cerebellar degeneration (PCD) is a type of paraneoplastic syndrome that primarily affects women with gynecological cancers. patients typically experience pancerebellar symptoms, including gait ataxia, dysarthria, nystagmus, and truncal and appendicular ataxia. We present the case of a 50-year-old woman with PCD and presumed ovarian cancer who initially complained of ataxia and dysarthria. PCD was diagnosed on the basis of her symptoms, diagnostic imaging, and laboratory work. PCD symptoms may precede the diagnosis of malignancy by months or years. early diagnosis and treatment of these syndromes, including rehabilitation, may result in improvements in quality of life for this population of patients.- - - - - - - - - - ranking = 445.70114078197keywords = cerebellar degeneration, degeneration, paraneoplastic (Clic here for more details about this article) |
3/16. rehabilitation treatment options for a patient with paraneoplastic cerebellar degeneration.paraneoplastic cerebellar degeneration is a neurologic syndrome associated with carcinoma. Medical management is limited to treatment of the underlying malignancy with excision, plasmapharesis, immunosuppression, or chemotherapy. We report on the case of a woman with paraneoplastic cerebellar degeneration who showed improvements in functional mobility after 3 wk of comprehensive inpatient rehabilitation. This case demonstrates the functional improvements of one patient with paraneoplastic cerebellar degeneration after intensive rehabilitation and describes the specific treatment interventions utilized.- - - - - - - - - - ranking = 2251.2679309727keywords = paraneoplastic cerebellar degeneration, cerebellar degeneration, degeneration, paraneoplastic (Clic here for more details about this article) |
4/16. Corticobasal syndrome with novel argyrophilic glial inclusions.A 42-year-old, left-handed woman first noted impaired dexterity of the dominant hand, soon followed by dysarthria and cognitive decline. Over a 4-year period, she developed severe left-sided apraxia with eventual neglect of the left arm and progressive extrapyramidal signs. Cognitive testing showed progressive executive, visuospatial, fluency, and naming impairment with relative preservation of memory. Single-photon emission computed tomography demonstrated asymmetric right posterior frontal and superior parietal hypoperfusion. The clinical impression was corticobasal degeneration. At autopsy, severe atrophy was seen in the perirolandic and frontal regions. There was marked neuronal loss and gliosis in the posterior frontal and precentral regions and less severe pathology in prefrontal, temporal, and parietal areas. Mild to moderate gliosis and neuronal loss were also seen in the putamen, globus pallidus, subthalamic, and dentate nuclei. Gallyas silver stain revealed numerous inclusions adjacent to oligodendrocyte nuclei in white and gray matter of affected cortical and subcortical regions. The gracile inclusions were wavy, slender, and stained positively with antibodies to ubiquitin and alphaB-crystallin but not to microtubule-associated proteins (tau, MAP1B, MAP2), tubulin, neurofilaments, glial fibrillary acidic protein, or alpha-synuclein. The argyrophilic inclusions identified in this case are distinct from those previously described in neurodegenerative diseases.- - - - - - - - - - ranking = 0.5keywords = degeneration (Clic here for more details about this article) |
5/16. Clinical insights into paraneoplastic cerebellar degeneration.neuroimaging is usually unremarkable in paraneoplastic cerebellar degeneration (PCD), at least in the early stages of the disease. A patient with proven PCD is reported in whom it could be shown that cerebellar atrophy evolved very rapidly and was present in early imaging studies. Even with the use of the whole spectrum of modern diagnostic tools, the underlying malignancy can be difficult to diagnose. In addition to mammography, MRI is recommended in these cases and repeat FDG-PET may be necessary.- - - - - - - - - - ranking = 1801.8435726359keywords = paraneoplastic cerebellar degeneration, cerebellar degeneration, degeneration, paraneoplastic (Clic here for more details about this article) |
6/16. A case of frontotemporal lobar degeneration with progressive dysarthria.We investigated the evolution of the neurological and neuropsychological characteristics in a right-handed woman who was 53-years-old at the onset and who showed personality changes and behavioral disorders accompanied by progressive dysarthria. She had hypernasality and a slow rate of speech with distorted consonants and vowels, which progressed as motor disturbances affecting her speech apparatus increased; finally, she became mute two years post onset. Her dysarthria due to bilateral voluntary facio-velo-linguo-pharyngeal paralysis accompanied with automatic-voluntary dissociation fit the description of anterior opercular syndrome. She showed personality changes and behavioral abnormalities from the initial stage of the disease, as is generally observed in frontotemporal degeneration (FTD), and her magnetic resonance image showed progressive atrophy in the frontotemporal lobes; thus, she was clinically diagnosed with FTLD. This patient's symptoms suggest that FTLD, including bilateral anterior operculum degeneration, causes progressive pseudobulbar paretic dysarthria accompanied by clinical symptoms of FTD, which raises the possibility of a new clinical subtype in the FTLD spectrum.- - - - - - - - - - ranking = 3keywords = degeneration (Clic here for more details about this article) |
7/16. An autopsy case of frontotemporal dementia with severe dysarthria and motor neuron disease showing numerous basophilic inclusions.We report a clinicopathological study of a patient suffering from frontotemporal dementia (FLD) with severe dysarthria and concomitant motor neuron disease (MND). The patient was a 52-year-old woman with almost simultaneous emergence of severe dysarthria and FTD. The severe dysarthria subsequently evolved into anterior opercular syndrome. Motor neuron signs then emerged, and the patient developed akinetic mutism approximately 2 years after the onset of the disease. The patient died of pneumonia after a 7-year clinical illness. Pathologically, severe and widespread degeneration in the frontal and temporal lobes, including the anterior opercular area, limbic system, basal ganglia, spinal cord and cerebellum, and frequent ubiquitin- and tau-negative basophilic inclusions were observed. The pyramidal tracts and anterior horns of the cervical cord also showed marked degeneration. Cases showing basophilic inclusions reported so far have been divided into two groups: early onset FTD and MND with basophilic inclusions. Our case presented clinicopathological features of both FTD and MND, which suggests that cases showing basophilic inclusions may constitute a clinicopathological entity of FTD/MND.- - - - - - - - - - ranking = 1keywords = degeneration (Clic here for more details about this article) |
8/16. Progressive loss of speech output and orofacial dyspraxia associated with frontal lobe hypometabolism.Three patients are described with slowly progressive loss of speech and dysarthria associated with orofacial dyspraxia, initially with intact written language, who subsequently developed more widespread cognitive abnormalities. Positron emission tomography (PET) revealed bifrontal hypometabolism in all of the patients, most marked in the inferior and lateral portions of both frontal lobes, with some extension into the parietal and temporal cortices in one case. These patients may represent a further example of focal progressive cortical degeneration.- - - - - - - - - - ranking = 0.5keywords = degeneration (Clic here for more details about this article) |
9/16. Opercular syndrome without opercular lesions: Foix-Chavany-Marie syndrome in progressive supranuclear motor system degeneration.A patient is described with slowly progressive supranuclear motor system degeneration (primary lateral sclerosis) characterized by pure bulbar spasticity for six years until a spastic tetraparesis developed. Clinically and electrophysiologically there was and still is no evidence of lower motor neuron involvement. Recently the patient presented with a syndrome of complete inability to move face and tongue voluntarily with preservation of the ability to move them "automatically", e.g. within gestures: automatic-voluntary motor dissociation. Loss of voluntary innervation of the facio-pharyngo-glossomasticatory muscles with preservation of involuntary innervation are the features of the Foix-Chavany-Marie syndrome, which to date has most often been described in association with bilateral vascular lesions of the opercula or their cortigofugal projections.- - - - - - - - - - ranking = 2.5keywords = degeneration (Clic here for more details about this article) |
10/16. Chronic progressive spinobulbar spasticity. A rare form of primary lateral sclerosis.Although it was first described over a century ago (by Charcot in 1865; by Erb in 1875), the concept of primary lateral sclerosis (PLS) is still not universally accepted. Despite this skepticism, several well-documented cases of isolated degeneration with varying degrees of involvement of corticospinal pyramidal pathways have been reported in the literature. The clinical manifestations in these cases can take one of two forms, ie, isolated spasmodic paraplegia or tetraplegia on the one hand or spasmodic tetraplegia associated with a pseudobulbar syndrome featuring severe spastic dysarthria (chronic progressive bilateral spinobulbar spasticity) on the other hand. Obviously, without firm pathologic data, PLS is a hazardous diagnosis for isolated paraplegia or tetraplegia. Conversely, for bilateral spinobulbar spasticity, it would appear to be the only diagnosis possible once investigate findings have eliminated the other possibilities, such as a pyramidal form of amyotrophic lateral sclerosis or a spinal form of multiple sclerosis. To underscore this point, in this report, five cases of chronic progressive bilateral spinobulbar spasticity developed over 5, 10, 12, 10, and 28 years, respectively, for which the only possible diagnosis was PLS. It was concluded that there are three forms of degenerative diseases of the principal motor pathways: one involving both central and peripheral neurons, ie, amyotrophic lateral sclerosis; one involving only peripheral neurons, ie, spinal amyotrophy; and one involving only central motor neurons, ie, PLS.- - - - - - - - - - ranking = 0.5keywords = degeneration (Clic here for more details about this article) |
