A 68-year-old right-handed woman was admitted to Tokyo Metropolitan Geriatric Hospital because of slowly progressive dysarthria and writing disability over 2-year period. On admission, severe dysarthria was observed, but no dysphagia. The dysarthria mostly resembled a type of pseudobulbar palsy, although it was associated with effortful speech production. An oro-facial apraxia was also found. She could name objects, and could understand spoken words correctly. Examination using the Western Aphasia Battery showed diminution of word fluency, impaired repetition and perseveration and writing errors. On the Wechsler Adult Intelligence Scale-R verbal IQ was 100 and performance IQ was 87. These scores did not suggest any significant degree of general intellectual deterioration. Wisconsin card sorting test disclosed mild frontal dysfunction. Magnetic resonance imaging showed cortical atrophy in the bilateral frontal and temporal lobes. Measurements of regional cerebral metabolic rate by 18F-FDG-PET demonstrated decreased uptake in the latero-dorso-inferior area of the bilateral frontal lobes, especially on the left side. The present case showed slowly progressive dysarthria and progressive aphasia without generalized dementia, and without typical aphasia. These symptoms are speculated to be related to the atrophy in the bilateral frontal and temporal lobes shown by MRI and the decreased metabolic rate in the left dominant bilateral frontal lobes on PET study. The pathologic process responsible for these lesions remains obscure.

Atypical dementias confront the adequacy of current diagnostic concepts. The two patients with atypical dementia syndromes described here shared common postmortem features of numerous neocortical neuritic (senile) plaques and microvascular amyloid, sparing of hippocampus and substantia nigra, and the virtual absence of neurofibrillary tangles. Microscopically, the two differed only by the presence of a few subcortical Lewy bodies in case 1. These similar morphologic features were associated with dramatically different clinical presentations. In the first patient, visual hallucinations, Capgras' syndrome, cognitive slowing, myoclonus, parkinsonism, and primitive reflexes evolved over 3 years. Memory and language were relatively spared. In the second, dysphagia, nonfluent aphasia, hypophonia, motor perseveration, and a severe disorder of attention developed during this 18-month illness. At autopsy, an unrecognized colon malignancy was found. Despite high neuritic plaque counts in cortex, neither the clinical nor the pathologic criteria for Alzheimer's disease adequately describe either case. The cases will be examined first as clinical, then as neuropathologic, entities. From this approach, we conclude that a specific clinical dementia syndrome may be expressed by several neuropathologic "diseases" and that a variety of clinical syndromes may represent a single neuropathologic diagnosis. This strategy identifies a conceptual dichotomy between Alzheimer's syndrome and postmortem Alzheimer's disease. Meticulous clinical and neuropathologic observation is essential in advancing an understanding of the relationship between the two.

We report a 71-year-old woman showing rapidly progressive non-fluent aphasia and dementia accompanied by motor neuron disease (MND). There was no family history of dementia or motor neuron disease. There was 10 months history of dysarthria and dysphagia. On examination, she showed profound difficulty in articulation. Her comprehension was impaired in that she was unable to obey three-stage command. Her written language was also impaired with phonological spelling errors, syntactic errors, and perseveration. Neuroradiological investigations showed atrophic changes and hypoperfusion of left temporal and bilateral parietal region revealed by MRI and SPECT, respectively. Her subsequent decline was rapid. It might be likely that aphasia is much more common in dementia with bulbar MND than is currently recognized because bulbar palsy might mask the language disorder.
