Recently, the accumulation of various proteins, such as tau, trans\u2010activation response DNA binding protein 43\u2009kDa (TDP<\/jats:styled-content>\u201043), and alpha\u2010synuclein (\u03b1S<\/jats:styled-content>yn), was reported in the brains of patients with ALS<\/jats:styled-content>\/PDC<\/jats:styled-content> in G<\/jats:styled-content>uam. To confirm whether similar findings are present in K<\/jats:styled-content>ii ALS<\/jats:styled-content>\/PDC<\/jats:styled-content>, we neuropathologically examined the brains and spinal cords of 18 patients with ALS<\/jats:styled-content>\/PDC<\/jats:styled-content> (clinical diagnoses: eight ALS<\/jats:styled-content> and 10 PDC<\/jats:styled-content>) in H<\/jats:styled-content>ohara V<\/jats:styled-content>illage, which is the eastern focus of K<\/jats:styled-content>ii ALS<\/jats:styled-content>. The average age at death was 71.6\u2009years, and 16 patients (88.9%) had a family history of ALS<\/jats:styled-content>\/PDC<\/jats:styled-content>. Autopsy specimens were immunohistochemically examined with antibodies against four major proteins. Neurofibrillary tangles, including ghost tangles, and tau\u2010positive astrocytes were distributed widely in all of the brains examined, and TDP<\/jats:styled-content>\u201043\u2010positive neuronal cytoplasmic inclusions were observed mainly in the limbic system. Synuclein pathology was present in 14 patients (77.8%). These patients were classified into three pathological subtypes according to the most prominent proteinopathy: the tauopathy\u2010dominant type, the TDP<\/jats:styled-content>\u201043 proteinopathy\u2010dominant type, and the synucleinopathy\u2010dominant type. Five patients with severe tau deposition showed clinical features of atypical parkinsonism and dementia with or without motor neuron disease. Eight patients were predominated by phosphorylated TDP<\/jats:styled-content>\u201043 inclusions and clinically showed ALS<\/jats:styled-content>, and five patients were predominated by synuclein pathology and clinically showed signs of PDC<\/jats:styled-content>. Based on the common characteristic tau pathology, three subtypes seemed to be pathologically continuous on a spectrum of a single disease. Thus, we conclude that ALS<\/jats:styled-content>\/PDC<\/jats:styled-content> in the H<\/jats:styled-content>ohara focus of the K<\/jats:styled-content>ii P<\/jats:styled-content>eninsula is a single disease characterized neuropathologically by a multiple proteinopathy, even though the clinical manifestations of the three subtypes differed from each other. It remains unclear whether the coexistence of the three proteinopathies was incidental or pathogenetically related.<\/jats:p>","DOI":"10.1111\/neup.12434","type":"journal-article","created":{"date-parts":[[2017,10,24]],"date-time":"2017-10-24T04:36:39Z","timestamp":1508819799000},"page":"98-107","source":"Crossref","is-referenced-by-count":51,"title":["Amyotrophic lateral sclerosis and parkinsonism\u2010dementia complex of the H<\/scp>ohara focus of the K<\/scp>ii P<\/scp>eninsula: A<\/scp> multiple proteinopathy?"],"prefix":"10.1111","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3452-0963","authenticated-orcid":false,"given":"Maya","family":"Mimuro","sequence":"first","affiliation":[{"name":"Department of Neuropathology Institute for Medical Science of Aging, Aichi Medical University Nagakute Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mari","family":"Yoshida","sequence":"additional","affiliation":[{"name":"Department of Neuropathology Institute for Medical Science of Aging, Aichi Medical University Nagakute Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigeki","family":"Kuzuhara","sequence":"additional","affiliation":[{"name":"School of Nursing Suzuka University of Medical Science Suzuka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasumasa","family":"Kokubo","sequence":"additional","affiliation":[{"name":"Kii ALS\/PDC Research Center Mie University, Graduate School of Regional Innovation Studies Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,10,23]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/mds.20548"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.100"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/84.4.662"},{"key":"e_1_2_8_5_1","first-page":"924","article-title":"Neurofibrillary degeneration in amyotrophic lateral sclerosis\/parkinsonism\u2010dementia complex of Guam.
