A 61-year-old woman with a history of photosensitive dermatitis and recurrent mouth ulcers presented with progressive weakness typical of amyotrophic lateral sclerosis (ALS), and subsequently underwent extensive neurologic and rheumatologic testing. We investigated whether ALS-like motor neuron disease associated with a positive antinuclear antibody (ANA) is really ALS or rather neuropsychiatric systemic lupus erythematosus (NPSLE). On neurologic evaluation, she had prominent bulbar involvement with dysarthria and dysphagia associated with profound lingual fasciculations and a denervating pattern on electromyogram. MRI showed no evidence of cerebral ischemia. Laboratory studies revealed a positive ANA (1:2560 titer), positive antiphospholipid antibodies (GPL and MPL), circulating lupus anticoagulant, and depressed C3 and C4. Repeat MRI studies at 4 and 11 mo revealed an evolving infarct in the paramedian pons consistent with the presence of NPSLE. Therapy was initiated with corticosteroids and intravenous cyclophosphamide, and the neurologic condition did not improve, but also did not progress inexorably as would be expected with ALS. NPSLE, presumably through the mechanism of ischemic vasculopathy, may present as motor neuron disease clinically indistinguishable from ALS.

We report an autopsy-confirmed case of amyotrophic lateral sclerosis (ALS) accompanied by syndrome of inappropriate secretion of antidiuretic hormone (SIADH). A 67-year-old man was admitted to our hospital with muscle weakness, dysarthria and dysphagia. During hospitalization, respiratory insufficiency was ingravescent, and hyponatremia, hypo-osmolarity, elevated osmotic pressure of urine, and elevated urinary sodium excretion were noted. Based on these findings we diagnosed ALS with SIADH, and treatment with infusion of concentrated NaCl was started. However, the patient died of respiratory failure on day 50. We assumed that severely restrictive ventilatory impairment was the cause of SIADH in this case.

We report a 63-year-old right-handed Japanese man with progressive bulbar dysfunction and alexia of kanji (Japanese morphograms). He was well until his 62 years of age, when he noted difficulty of reading kanji, which was followed by disturbances in his speech. Reading of kana (Japanese phonograms) was preserved. He also showed naming difficulties with semantic memory loss for words, which were characterized for word meaning aphasia or semantic dementia. He showed dysarthria and mild dysphagia with atrophy and fasciculations of the tongue. The electromyographic studies disclosed diffuse neurogenic pattern. He was diagnosed as having bulbar type amyotrophic lateral sclerosis. Cranial magnetic resonance imaging and single-photon emission computed tomography revealed bilateral involvements of the temporal lobes. Our patient appeared to meet the clinical criteria for frontotemporal degeneration of motor neuron disease type, and is the first case of amyotrophic lateral sclerosis showing alexia of kanji and word meaning aphasia.

This report concerns an autopsy case of amyotrophic lateral sclerosis (ALS) with circumscribed temporal atrophy. The patient was a Japanese woman without hereditary burden who was 71-year-old at the time of death. She developed dysarthria and gait disturbance at age 69, followed by dysphagia. A neurological examination about 1 year 11 months after the onset of the disease revealed absence of character change and of dementia. Neuroradiological examination disclosed circumscribed atrophy of the anterior part of the right temporal lobe. The patient died of respiratory failure 2 years after the disease onset. No respirator administration was performed throughout the clinical course. Macroscopically, neuropathological examination showed circumscribed atrophy of the right first temporal gyrus. Histologically, there was neuronal loss in the cerebral cortex, including the first temporal gyrus, the parahippocampal gyrus, subiculum, amygdala, substantia nigra, brain stem motor nuclei, and anterior horns of the spinal cord, in addition to loss of Betz cells, obvious degeneration of the pyramidal tracts, and the presence of Bunina bodies. Ubiquitin-immunoreactive intraneuronal inclusions were present in the hippocampal dentate granular cells, frontotemporal cortical layer II neurons, and motor neurons in the brain stem and spinal cord. Based on these clinicopathological findings and a review of the literature, we concluded that our case was atypical ALS without dementia, showing temporal lobe atrophy macroscopically, in addition to pathological hallmarks compatible with ALS with dementia. We also note the possibility that there is a forme fruste of ALS with dementia showing no overt dementia clinically.

We describe a patient with amyotrophic lateral sclerosis with dementia (ALS-D) displaying a long clinical course. A 68-year-old Japanese male with no family history of note was admitted complaining of severe dysarthria and dysphagia. At 63 years old, Pick's disease was diagnosed on the basis of abnormal behavior, such as "Denkfaulheit" and moria, and temporal lobe atrophy observed on magnetic resonance imaging (MRI). Five years after onset, dysarthria and dysphagia emerged, and gradually worsened. On admission, muscular weakness of the upper extremities, fasciculation, and exaggerated tendon stretch reflexes were noted. Needle electromyography performed on the left upper and lower extremities revealed neurogenic pattern changes. Based on these findings and clinical course, ALS-D was diagnosed. Due to severe bulbar palsy, verbal communication was impossible. However, neither specific symptoms of dementia nor abnormal behavior was demonstrated, although this latter had been observed 5 years ago, with only short-term memory impairment apparent. MRI disclosed severe knife-edge atrophy of bilateral temporal lobes, most prominently in the anterior regions. SPECT images revealed decreased uptake of tracer in bilateral inferior temporal lobes, predominantly on the left side. The patient died suddenly 4 months after admission, and post-mortem examination was not conducted. Total clinical course was about 8 years. Several cases of ALS-D have displayed similar clinical courses to the presented case. Some of these would also have initially been diagnosed as Pick's disease. We speculate that cases displaying psychiatric symptoms for several years and initially diagnosed as Pick's disease may finally be diagnosed as ALS-D upon the eventual emergence of motor symptoms(bulbar palsy).

We report a case of amyotrophic lateral sclerosis (ALS) with IgM antibody against gangliosides GM2 and GD2. A 57-year-old woman presented with slowly progressive muscular weakness of the upper extremities and dysarthria. She fulfilled the clinical and electrophysiological criteria of ALS, and died from sudden suffocation about 3 years after the onset of illness. The patient's serum IgM antibody was shown to recognize the structure shared by GM2 and GD2. Since anti-GM2 antibodies have been implicated in motor neuropathy or motor neuron syndrome, this rare case might contribute to the understanding of the immunological aspects of ALS.

Hallervorden-Spatz syndrome (HSS) is a neurodegenerative disorder characterized by progressive dementia, dystonia, ataxia, and rigidity. An atypical form of adult-onset HSS was observed in a 36-year-old man presenting with progressive dysarthria. Markedly dysarthric speech and a weak atrophic tongue associated with a neurogenic pattern of motor unit recruitment in bulbar-supplied muscles on electromyography led to an initial impression of bulbar amyotrophic lateral sclerosis (ALS). Lack of expected progression of symptoms, however, prompted reinvestigation. Repeat brain magnetic resonance imaging demonstrated an "eye-of-the-tiger" pattern in the basal ganglia, characteristic of HSS, thus requiring genetic studies. DNA analyses of the pantothenate kinase gene (PANK2) was conducted and revealed two novel, disease-causing exon 3 missense mutations (Cys231Ser and Tyr251Cys). This case broadens the genotypic and phenotypic spectrum of HSS to include a late-onset syndrome resembling bulbar-onset ALS.

Phonatory dysfunction is a frequent component of dysarthria and often is a primary feature noted in clinical assessment. But the vocal impairment can be difficult to assess because (a). the analysis of voice disorder of any kind can be challenging, and (b). the voice disorder in dysarthria often occurs along with other impairments affecting articulation, resonance, and respiration. A promising assessment tool is multi-parameter acoustic analysis, such as the Multi-Dimensional Voice Program (MDVP). Part 1 of this paper recommends procedures and standards for the acoustic analysis of voice, including (1). selection of the sample to be analyzed, (2). signal quality requirements, (3). availability of normative data for both genders and different ages of speakers, (4). reliability of analysis, and (5). correlation of acoustic results with results from other methods of analysis. In Part 2, acoustic data are reviewed for the dysarthria associated with Parkinson disease (PD), cerebellar disease, amyotrophic lateral sclerosis (ALS), traumatic brain injury (TBI), unilateral hemispheric stroke, and essential tremor. Tentative profiles of voice disorder are described for these conditions. These profiles may serve as hypotheses for future research. Although several issues remain to be resolved in the acoustic analysis of voice disorder in dysarthria, steps can be taken now to promote the reliability, validity, and clinical utility of such analyses. (1). As a result of this activity, the participant will be able to describe ways in which an optimal multi-dimensional analysis of voice can be performed with modern acoustic analysis systems. (2). As a result of this activity, the participant will be able to apply multi-dimensional acoustic analysis of voice to individuals who have a dysarthria-related voice disorder. (3). As a result of this activity, the participant will be able to identify major sources of normative data on the Multi-Dimensional Voice Program.

Articulatory discoordination is often said to be an important feature of the speech production disorder in dysarthria, but little experimental work has been done to identify and specify the coordination difficulties. The present study evaluated the coordination of labial and lingual gestures for /u/ production in persons with Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and in control participants. Both tongue backing/raising and reduction of the area enclosed by the lips can produce the characteristic low F2 of /u/. The timing of these articulatory gestures with respect to the acoustic target of a low F2 was inferred from X-ray microbeam data. Pellet motions of the tongue dorsum and lips revealed the timing of the lingual and labial gestures to be strongly linked together (synchronized), predictive of the temporal location of the lowest F2 within the vocalic nucleus, and scaled proportionately to the overall vowel duration in control participants. Somewhat surprisingly, essentially the same findings were obtained in the speakers with dysarthria. These relationships were noisier among the speakers with dysarthria, but the global synchronization patterns applied to all 3 groups. Further analyses revealed the synchronization to be less well defined and more variable across speakers with ALS, as compared to speakers with PD and the controls. Results are discussed relative to concepts of coordination in dysarthria.

Progressive dysarthria is a common sign of several degenerative disorders of the central nervous system; it may also be a distinct nosographic entity. We identified nine patients in which progressive dysarthria remained the sole neurological sign for at least 2 years after onset. At least a year after hospital admission, the following diagnoses were made: two cases of corticobasal degeneration, one of frontotemporal dementia, one of primary progressive aphasia, one of motor neuron disease (MND)-dementia, one of ALS, and one of ALS-aphasia. In the remaining two patients progressive dysarthria remained the only neurological sign at latest examination. We conclude that in most cases progressive dysarthria is the presenting sign of an established neurodegenerative disease (generally degenerative dementia or motor neuron disease), although the possibility that progressive dysarthria is a distinct entity cannot be excluded. To clarify this issue, studies (probably multicenter) on more patients with longer clinical follow-up and pathological confirmation are required.
