Journal ArticleDOI
Tau in cerebrospinal fluid: A potential diagnostic marker in Alzheimer's disease
Hiroyuki Arai,Masanori Terajima,Masakazu Miura,Susumu Higuchi,Taro Muramatsu,Nobuo Machida,Hisatomo Seiki,Sadao Takase,Christopher M. Clark,Virginia M.-Y. Lee,John Q. Trojanowski,Hidetada Sasaki +11 more
TL;DR: The results suggest that cerebrospinal fluid tau might reflect the progressive accumulation of altered tau due to the progressive death of neurons in the AD brain, and that the enzyme‐linked immunosorbent assay of cerebro Spinal Fluid tau may prove to be a reliable and early diagnostic test for AD.
Journal ArticleDOI
Elevated Plasma Homocysteine Levels and Risk of Silent Brain Infarction in Elderly People
Toshifumi Matsui,Hiroyuki Arai,Takefumi Yuzuriha,Hiroshi Yao,Masakazu Miura,Setsuko Hashimoto,Susumu Higuchi,Sachio Matsushita,Masatoshi Morikawa,Atsushi Kato,Hidetada Sasaki +10 more
TL;DR: Community-dwelling elderly people aged ≥66 years who participated in the present study underwent brain MRI and standardized physical and neuropsychological examinations as well as blood biochemistry determinations, and pHcy level is associated with age and nutritional and other lifestyle factors, and it contributes to a risk for Silent brain infarction.
Journal ArticleDOI
Cerebrospinal fluid tau levels in neurodegenerative diseases with distinct tau-related pathology.
Hiroyuki Arai,Yu Ichi Morikawa,Makoto Higuchi,Toshifumi Matsui,Christopher M. Clark,Masakazu Miura,Nobuo Machida,Virginia M.-Y. Lee,John Q. Trojanowski,Hidetada Sasaki +9 more
TL;DR: This study suggests that tau may accumulate in the CSF of patients with certain neurodegenerative diseases other than AD and that measurement of CSF-tau may not distinguish AD from DLB.
Journal ArticleDOI
No increase in cerebrospinal fluid tau protein levels in patients with vascular dementia
Hiroyuki Arai,Takuma Satoh-Nakagawa,Makoto Higuchi,Yu Ichi Morikawa,Masakazu Miura,Hisako Kawakami,Hisatomo Seki,Sadao Takase,Hidetada Sasaki +8 more
TL;DR: It is suggested that VD constitutes a group of dementias that can be separated from AD by normal CSF-tau levels, and CSF/ml determinations in combination with other clinical findings may provide another diagnostic aid in the differential diagnosis between VD and AD.
Journal ArticleDOI
Cerebrospinal fluid tau protein levels in demented and nondemented alcoholics.
Yu Ichi Morikawa,Hiroyuki Arai,Sachio Matsushita,Motoichiro Kato,Susumu Higuchi,Masakazu Miura,Hisako Kawakami,Makoto Higuchi,Nobuyuki Okamura,M. Tashiro,Toshifumi Matsui,Hidetada Sasaki +11 more
TL;DR: It is suggested that alcohol-induced organic brain disorders are a group of dementias that are characterized by normal CSF-tau levels, and that the CSF examination for tau in combination with other clinical findings may help in differentiating alcohol- induced Organic brain disorders from AD.
