The number of patients with intractable epilepsy undergoing surgical management in China is increasing rapidly. We retrospectively reviewed 435 consecutive cases of intractable epilepsy receiving surgical resection from 2005 to 2008 in our hospital, looking specifically at the neuropathological findings. The three most common causes of intractable epilepsy(More)
We report the autopsy findings of an 82-year-old woman who exhibited slowly progressive upper motor neuron signs (pseudobulbar palsy, muscle weakness and positive Babinski's sign) in the absence of lower motor neuron signs, which were followed by progressive dementia and frontotemporal atrophy, and who died 7 years and 4 months after onset of the disease.(More)
BACKGROUND Multiple system atrophy (MSA) is diverse in clinical phenotype, disease progression, and prognosis. Sudden death is a leading cause of death in patients with MSA. OBJECTIVE To determine what clinical factors affect the progression and survival prognosis of those with MSA. DESIGN A retrospective review of the medical records of 49 consecutive(More)
Due to brain tissue heterogeneity, the molecular genetic profile of any neurotransmitter-specific neuronal subtype is unknown. The purpose of this study was to purify a population of dopamine neurons, construct a cDNA library, and generate an initial gene expression profile and a microarray representative of dopamine neuron transcripts. Ventral(More)
Sporadic amyotrophic lateral sclerosis (ALS) is a fatal neurological disorder affecting adults. We studied the neuropathology and clinical correlations in 102 autopsy cases of ALS. The age at onset of the disease was significantly higher for the bulbaronset form (30 cases) than for the limb-onset form (72 cases). Dementia was confirmed in 7 cases. These 102(More)
Abnormalities in tau mRNA splicing cause frontotemporal dementia and parkinsonism linked to chromosome 17, and similar alterations are suggested in sporadic tauopathies such as progressive supranuclear palsy (PSP) or corticobasal degeneration (CBD). We have analyzed the expression of three-repeat (3R) and four-repeat (4R) tau isoforms in brains with(More)
Alpha-synuclein has an important role in the pathogenesis of Parkinson disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), comprising a new disease concept, that of alpha-synucleinopathies. Cerebellar degeneration with Purkinje cell depletion is present in the majority of MSA cases. By contrast, cerebellar pathology has not(More)
We report early-onset parkinsonism and dementia of 18 years' duration in a 52-year-old man whose grandfather and father had suffered from a similar neurological disease. In this patient, we found neuronal loss in various brain regions including the substantia nigra and cerebral cortex, Lewy bodies, cotton wool plaques, corticospinal tract degeneration,(More)
Tau is the pathological protein in several neurodegenerative disorders classified as frontotemporal lobar degeneration (FTLD), including corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP). We report an unusual tauopathy in three Japanese patients presenting with Parkinsonism and motor neuron disease (neuroimaging revealed(More)
We report two patients who exhibited frontotemporal dementia (FTD) with unusual neuropathological features. The ages of the patients at death were 65 and 67 years, the disease durations were 6 and 5 years, and the clinical diagnoses were Pick's disease and corticobasal degeneration (CBD), respectively. At autopsy, both cases exhibited neuropathological(More)
