Current and Past Project
  • Clinicopathological study on dementia: the Hisayama study.
    The Hisayama study is a prospective population-based study in a Japanese subrural community, Hisayama Town, which has been carried out by Department of Medicine and Clinical Science, Kyushu University since 1961. The characteristic of the town is that the age, occupational status and nutrient intake of the population are almost identical to those of the general Japanese population. Postmortem examinations of most deceased subjects were performed in Kyushu University Hospital to confirm causes of death and to examine brain pathology. These features have allowed a reliable estimation of the frequency of neurodegenerative diseases relating dementia in a general population and for a detailed analysis of the difference between dementia and non-dementia. Our database based on the Hisayama study would have benefits to examine clinicopathological features of neurodegenerative diseases in a general population.

Breteler, Hiroyuki Honda, Carol Brayne, The changing prevalence and incidence of dementia over time current evidence, Nature Reviews Neurology, 10.1038/nrneurol, 13, 6, 327-339, 2017.06, Dementia is an increasing focus for policymakers, civil organizations and multidisciplinary researchers. The most recent descriptive epidemiological research into dementia is enabling investigation into how the prevalence and incidence are changing over time. To establish clear trends, such comparisons need to be founded on population-based studies that use similar diagnostic and research methods consistently over time. This narrative Review synthesizes the findings from 14 studies that investigated trends in dementia prevalence (nine studies) and incidence (five studies) from Sweden, Spain, the UK, the Netherlands, France, the USA, Japan and Nigeria. Besides the Japanese study, these studies indicate stable or declining prevalence and incidence of dementia, and some provide evidence of sex-specific changes. No single risk or protective factor has been identified that fully explains the observed trends, but major societal changes and improvements in living conditions, education and healthcare might have favourably influenced physical, mental and cognitive health throughout an individual’s
life course, and could be responsible for a reduced risk of dementia in later life. Analytical epidemiological approaches combined with translational neuroscientific research could provide a unique opportunity to explore the neuropathology that underlies changing occurrence of dementia in the general population.

The incubation period has ranged from 1 to 30 years and the age at onset from 15 to 80 years. Here, we report a 77-year-old male Japanese autopsied dCJD case with the longest incubation period so far in Japan. He received a cadaveric dural graft at the right cranial convexity following a craniotomy for meningioma at the age of 46. At 30 years post-dural graft placement, disorientation was observed as an initial symptom of dCJD. He rapidly began to present with inconsistent speech, cognitive impairment and tremor of the left upper extremity. Occasional myoclonic jerks were predominantly observed on the left side. Brain MRI presented hyperintense signals on diffusion-weighted and T2-weighted images, at the right cerebral cortex. The most hyperintense lesion was located at the right parietal lobe, where the dura mater graft had been transplanted. Single-photon emission CT scan showed markedly decreased cerebral blood flow at the right parietal lobe. EEG revealed diffuse and slow activities with periodic sharp-wave complex discharges seen in the right parietal, temporal and occipital lobes. He died of pneumonia 9 months after onset. Brain pathology revealed non-plaque-type dCJD. Laterality of neuropathological changes, including spongiform change, neuronal loss, gliosis or PrP deposits, was not evident. Western blot analysis showed type 1 PrPCJD . Alzheimer-type pathology and PSP-like pathology were also observed..

Masahiro Shijo, Hiroyuki Honda, Satoshi O Suzuki, Toru Iwaki, Association of adipocyte enhancer-binding protein 1 with Alzheimer’s disease pathology in human hippocampi, Brain Pathology, 10.1111/bpa.12475., Epub ahead of print, 2016.12, Adipocyte enhancer binding protein 1 (AEBP1) activates inflammatory responses via the NF-jB pathway in macrophages and regulates adipogenesis in preadipocytes. Up-regulation of AEBP1 in the hippocampi of patients with Alzheimer’s disease (AD) has been revealed by microarray analyses of autopsied brains from the Japanese general population (the Hisayama study). In this study, we compared the expression patterns of AEBP1 in normal and AD brains, including in the hippocampus, using immunohistochemistry. The subjects were 24 AD cases and 52 non-AD cases. Brain specimens were immunostained with antibodies against AEBP1, tau protein, amyloid b protein, NF-jB, GFAP and Iba-1. In normal brains, AEBP1 immunoreactivity mainly localized to the perikarya of hippocampal pyramidal neurons, and its expression was elevated in the pyramidal neurons and some astrocytes in AD hippocampi. Although AEBP1 immunoreactivity was almost absent in neurons containing neurofibrillary tangles, AEBP1 was highly expressed in neurons with pretangles and in the tau-immunopositive, dystrophic neurites of senile plaques. .
