Journal ArticleDOI
123I-MIBG myocardial scintigraphy for differentiating Parkinson's disease from other neurodegenerative parkinsonism: a systematic review and meta-analysis.
TL;DR: The present meta-analysis confirmed high sensitivity and specificity of (123)I-MIBG myocardial scintigraphy for differentiating PD from other neurodegenerative parkinsonism in both early and delayed imaging phases and was highly effective for distinguishing early PD.
Journal ArticleDOI
Randomized, double-blind, placebo-controlled trial of vitamin D supplementation in Parkinson disease
Masahiko Suzuki,Masayuki Yoshioka,Masaya Hashimoto,Maiko Murakami,Miki Noya,Daisuke Takahashi,Mitsuyoshi Urashima +6 more
TL;DR: Vitamin D3 supplementation may stabilize PD for a short period in patients with FokI TT or CT genotypes without triggering hypercalcemia, although this effect may be nonspecific for PD.
Journal ArticleDOI
Shortening of simple reaction time by peripheral electrical and submotor-threshold magnetic cortical stimulation
Yasuo Terao,Yoshikazu Ugawa,Masahiko Suzuki,Katsuyuki Sakai,Ritsuko Hanajima,Kieko Gemba-Shimizu,Ichiro Kanazawa +6 more
TL;DR: Much of the effect of TMS on simple reaction time is due to intersensory facilitation, although part of it may be ascribed to a specific effect on the excitability of motor cortex.
Journal ArticleDOI
Adenosine A2A Receptors Measured with [11C]TMSX PET in the Striata of Parkinson's Disease Patients
Masahiro Mishina,Kiichi Ishiwata,Mika Naganawa,Yuichi Kimura,Shin Kitamura,Masahiko Suzuki,Masaya Hashimoto,Kenji Ishibashi,Keiichi Oda,Muneyuki Sakata,Makoto Hamamoto,Shiro Kobayashi,Yasuo Katayama,Kenji Ishii +13 more
TL;DR: It is suggested that the A2ARs in the putamen compensate for the asymmetrical decrease of dopamine in drug-naïve PD patients and that antiparkinsonian therapy increases the A1A receptors in thePutamen.
Journal ArticleDOI
Impaired myocardial 123I-metaiodobenzylguanidine uptake in Lewy body disease: comparison between dementia with Lewy bodies and Parkinson's disease.
Masahiko Suzuki,Akira Kurita,Masaya Hashimoto,Nobuyoshi Fukumitsu,Masahiro Abo,Yasuhiko Ito,Mitsuyoshi Urashima,Kiyoharu Inoue +7 more
TL;DR: The findings suggest that cardiac sympathetic function in DLB is severely impaired even in the early disease stage, and 123I-MIBG uptake of the myocardium was significantly lower in patients with early DLB than in controls.
